General Information

  • What is Sleep Apnea?

    Sleep apnea affects the way you breathe when you're sleeping. When left untreated your breathing is briefly interrupted or becomes very shallow during sleep. This typically will cause pauses that last between 10 to 20 seconds and can occur up to hundreds of times a night, jolting you out of your natural sleep rhythm. The end result is spending more time in light sleep and less time in the deep, restorative sleep that allows you to be energetic, mentally sharp, and productive the next day.

    This chronic sleep deprivation results in daytime sleepiness, slow reflexes, poor concentration, and an increased risk of accidents. Sleep apnea can also lead to serious health problems over time, including diabetes, high blood pressure, heart disease, stroke, and weight gain. In conjunction with treatment you can control the symptoms, get your sleep back on track, and start enjoy being refreshed and alert every day.

    Types of Sleep Apnea

    • Obstructive sleep apnea is the most common type of sleep apnea. It occurs when the soft tissue in the back of your throat relaxes during sleep and blocks the airway, often causing you to snore loudly.
    • Central sleep apnea is a much less common type of sleep apnea that involves the central nervous system, occurring when the brain fails to signal the muscles that control breathing. People with central sleep apnea seldom snore.
    • Complex sleep apnea is a combination of obstructive sleep apnea and central sleep apnea.

    What Are the Symptoms of Obstructive Sleep Apnea?

    • Daytime sleepiness or fatigue
    • Dry mouth or sore throat upon awakening
    • Headaches in the morning
    • Trouble concentrating, forgetfulness, depression, or irritability
    • Night sweats
    • Sexual dysfunction
    • Snoring
    • Sudden awakenings with a sensation of gasping or choking
    • Difficulty getting up in the morning

    Signs and symptoms of sleep apnea in children

    While obstructive sleep apnea can be common in children, it's not always easy to recognize. In addition to continuous loud snoring, children with sleep apnea may adopt strange sleeping positions and suffer from bed-wetting, excessive perspiration at night, or night terrors.

    If you suspect your child may have sleep apnea, consult a pediatrician who specializes in sleep disorders. Once obstructive sleep apnea is diagnosed, surgery to remove the child's tonsils or adenoids usually corrects the problem.

    Risk Factors for obstructive sleep apnea

    • Overweight
    • Related to someone who has sleep apnea
    • Commonly Male
    • Over the age of 65
    • A smoker

    Lifestyle changes that can help patients with sleep apnea

    • Quit smoking
    • Avoiding Alcohol
    • Avoiding caffeine and heavy meals
    • Maintaining regular sleep hours
    • Healthy diet and exercise Sleep Apnea test

    1. Do you snore more than three nights a week?
      Yes (2 points) No (0 points)
    2. Is your snoring loud (can it be heard through a door or wall)?
      Yes (2 points) No (0 points)
    3. Has anyone ever told you that you briefly stop breathing or gasp when you are asleep?

      Yes (2 points) No (0 points)

    Interpreting the score:

    • 0 to 5: Low probability of sleep apnea. You're sleep problems are more likely to be caused by something other than sleep apnea. Consult your doctor for a diagnosis.
    • 6 to 8: It's uncertain whether you have sleep apnea. You and your doctor should decide the next step based on other pieces of your medical history.
    • 9 +: You may have sleep apnea. You are a good candidate for a sleep study and should see your doctor immediately

    We have created these frequently asked questions to help smooth out the process and provide more information for our international customers.

    Do You Have Someone that Speaks my Foreign Language?

    Our employees are trained and provide translation service in most languages through our customer service chat room. Don't hesitate to give it a try.

    Do you ship CPAP machines, CPAP masks and supplies to My Country?

    Yes, we ship most items internationally. Ask an associate for details.

    Where can I find my estimated delivery date?

    Once your order has been submitted, a confirmation email will be sent to you. This email will include shipping and delivery time estimates. These estimates will also appear under "My Account”.

    Do you offer rush shipping?

    Expedited shipping is available, including 2-Day and Next Day (with the addition of Saturday Air under certain circumstances). Orders must be submitted prior to 11:00am Pacific Standard Time in order to receive expedited delivery in the time frame specified. Expedited orders placed after 11:00am Pacific Standard Time or on Saturday/Sunday normally ship the next business day. Some orders may be subject to verification of billing/shipping information and may therefore be delayed.

    We work tirelessly to have your shipment arrive within the specified time frame. During times of heavy order volume, expedited shipments may take longer to process. Therefore, we recommend you plan accordingly. To ensure delivery time frames, order early during peak times and holidays, such as Easter, Mother's Day, Thanksgiving, Christmas and New Year's, as well as when schools resume in late-August and mid-January.

    How can I calculate my shipping costs?

    When placing your order, you may choose from several methods of shipment and you will be able to select the method and pricing that best fits your needs.

    Does the shipping cost include duty or tax?


    What locations do you ship from?

    Stock orders ship from our distribution centers located in Redmond, WA, USA. Shipping charges are automatically calculated using the closest distribution center as the point of origin. We reserve the right to ship certain products or orders directly to a customer from the manufacturer. In these cases, freight costs, if any, will be calculated using the manufacturer as the point of origin.

    What shipping methods do you use?

    We ship orders to both commercial and residential addresses. Commercial addresses are defined as business addresses situated on commercially zoned real estate, as determined by the freight carrier. Businesses operated from a house, apartment or other dwelling are not considered commercial addresses and will be charged any applicable residential delivery fees.

    Will I be charged for freight fees?

    Orders of free freight eligible products that subtotal under $250 that are shipping to the same address will be assessed freight and handling charges, unless otherwise indicated. When ordering factory direct items not stocked in our warehouse, a freight charge may be assessed in accordance with the freight chart. After you finish adding items to the Shopping Cart, you will receive Standard Ground and Expedited shipping options to best meet your needs. Though not standard, inside delivery is available for an additional fee.

  • Order Information

  • Do you bill my insurance company?

    Currently does not directly bill Medicare or private insurances. We are not a participating provider with any insurance companies. However, we will provide our customers with any information needed to fill out an insurance claim form.

    Customers are advised to contact their insurance prior to making a purchase at Respshop. This is to ensure their out-of-network benefits will cover purchases made from out-of-network providers. Also, check with your insurance for documents needed from a physician i.e. a copy of a prescription, Letter of Medical Necessity, Medical Certification, Pre-Authorization letter/number, etc., to submit these documents along with their claim form. Please check also about your yearly deductible for your plan. In some cases, it is cheaper to purchase a CPAP machine from Respshop than to go through your insurance after meeting your requirements such as co-pays and deductibles.

    Most insurance companies will reimburse you, if Medicare pays. Normally Medicare will pay 80% of the total amount; a secondary insurance will pick up the 20% unless stated in their policy. If a customer has a third or tertiary insurance, it will pick up the remainder from the secondary insurance, otherwise the remaining amount is the customer’s responsibility.

    Insurance policies vary. Be sure to check with your specific provider before making any purchases.

  • CPAP Machine FAQ

  • How do I travel with my CPAP?

    Traveling with your machine can sometimes be a hassle. However, with proper preparation, it can be very easy. If you are flying with it, you can bring it on the plane with you and it will not count as one of your carry-on items. Never check your CPAP machine because through normal luggage handling procedures it can easily be broken. You may want to call ahead and find out airline procedures for carrying your machine on the plane to prevent any delays through security. We have learned that many airlines will not let you use your CPAP machine during the flight because it is not a life-sustaining device. You may want to contact your airline to see if you can make special arrangements. This link will also provide helpful information.

    If you are driving across country with your CPAP or are camping, you can still use your machine (depending on the make and model). If your machine has the ability to run off of 12V (check your owner’s manual) then you will be able to run your machine off of either a battery, or plug it into the cigarette lighter adapter in your car / RV if you purchase the proper cables. Respironics sells battery adapter cables for those who wish to bring their CPAP camping in the wilderness. A 12V deep cycle marine battery or a motorcycle battery is recommended for the longest life between charges. The life span of the battery depends on its rating and what your pressure setting is on your machine.

    10 Tips Traveling with your CPAP Machine

    Flying with Your CPAP. The Federal Aviation Administration (FAA) recently ruled that airline passengers must be allowed to use respiratory assistent devices, such as a CPAP machine (Nondiscrimination on the Basis of Disability in Air Travel – May 13, 2009). However, don't think that you'll just breeze by security checkpoints at the airport. Here are some common tips that are recommended when you fly with your CPAP machine:

    1. Never check your CPAP machine.
    2. Always have with you a prescription for your CPAP machine and your latest sleep study. You never know if your unit gets lost or stolen, or breaks down.
    3. Attach a medical equipment tag, identifying the contents as such.
    4. Let the TSA security agent know that you have a CPAP machine. Remove it from the back and have it scanned separately.
    5. Request that security agents change gloves and wipe down the table before inspecting your machine. Wrap your device in a clear bag while being scanned to prevent contamination with germs and other chemicals.
    6. Keep a record of the model and serial number in hand, just in case.
    7. If you're going to use your CPAP machine in-flight, check beforehand if there's an outlet next to your seat, and if you have the right adapter.
    8. If the flight attendant says something about your CPAP being another carry-on, let him or her know that it's a CPAP machine and under the Americans with Disability Act, it's not counted as an added carry-on.
    9. Consider having your doctor give you a letter describing the need for your CPAP machine.
    10. Most CPAP units will automatically convert to the correct local voltage. Check with your instruction manual or manufacturer to confirm this. You may, however, need a plug adapter, as well as an extension cord, in case your outlet is far away.

    What is CPAP?

    CPAP stands for Continuous Positive Airway Pressure. CPAP therapy provides a constant airflow which holds the airway open so that uninterrupted breathing is maintained during sleep. This eliminates Sleep Apnea and allows the patient to get a restful sleep. CPAP therapy is traditionally provided through a nasal mask that seals around the nose. However, more innovative, comfortable and better sealing options are beginning to emerge. Check out the CPAP machines here.

    What is an Auto CPAP machine?

    An Auto CPAP machine is a machine that uses two pressure settings; a high setting and a low setting. The machine starts at the lower setting (typically 3-4 cm below your normal CPAP pressure) and through the course of the night it senses when you are having an apnea occur. It then begins to slowly raise the pressure toward the set high pressure. Once the apnea is overcome, it will stay at that pressure for a period of time and then slowly begin to decrease back toward the low pressure. If another apnea occurs in the meantime, it will then begin to increase, so on and so forth. In this way, the machine automatically figures out the best pressure for you to be sleeping at for that particular night. This is a nice feature because your best therapy pressure is not always the same. It greatly depends on your daily activities and your personal habits. Check out the Auto CPAP machines here.

    Which Machine Should I Choose?

    There is a great deal of information on the internet concerning CPAP Machines. While most of this information is accurate, please seek out as much information as possible. Things to consider are: type of usage, do you travel; do you need humidification, weight of the machine, size of the machine, noise level, etc.

    Do your CPAP machines support 110v or 240v voltage?

    All machines we sell support 100v - 240v AC auto conversion. You can use these machines anywhere around the world without a problem. However you may need a plug converter which can be purchased in the most hardware stores for a few bucks

    Why do I have shortness of breath, while using the CPAP machine?

    • The ramp air pressure may be too low, once you raise the ramp air pressure you should no longer have shortness of breath.
    • If you are feeling anxious you might feel shortness of breath and will feel like you need to take quick brief breaths, at this time breathe normally, take big deep breaths and relax.
    • The machines function may not be at top performance, sometimes the mask may not be giving you enough air pressure. When exhaling not enough carbon dioxide is released, the pressure goes up and can make you feel tired. This could be the motor function, or other technical problems. To continue the use of the machine as it will hinder your treatment.

    What is a BiLevel (BiPAP) machine?

    A Bi-Level machine, or as some call it a BiPAP machine uses two pressure settings for your therapy: An respiratory pressure and an expiratory pressure. When you inhale, the therapy is delivered at the set respiratory pressure, when you exhale, the pressure is delivered at the set expiratory pressure. The respiratory pressure is always greater than the expiratory pressure. This type of machine is usually used for people who cannot tolerate a normal CPAP machine or for people who have other conditions along with their Sleep Apnea. Check out the BPAP/VPAP machine we sell online here and here.

    Why do I feel bloated when I wake up in the morning?

    Sometimes the air pressure is too high and the air can go into your stomach, you should see a professional to help adjust the settings.

    How often should I change my filters, tubing, and water chambers?

    For filters, if you are using the white, disposable filters, you should change them whenever you start to see them get fairly dirty. Remember, this is the air you are breathing at night! If you have the foam, reusable filters, then you should rinse them out and let them air dry at least once every other week. Medicare guidelines suggest that you replace your tubing every 30 days. This may be a little too often so we recommend replacing your tubing once every three months. This is because dirt and bacteria can build up in your tubing and that can cause you to become ill. Water chambers should be replaced at least once every 6 months.

    Which machine is the quietest?

    All new machines these days are extremely quiet compared to older model machines. Patients will hear the noise from the air venting out of their CPAP masks before they will ever notice the noise from their CPAP machine. This is why it is recommended that when you shop for a new machine; look for other features like size, comfort features or the option of an integrated humidifier.

    Are there DC/Battery operated CPAP machines?

    Most CPAP/APAP/Bipap-Vpap machine are designed to operate also in DC 12v/24v but manufacturers recommend to use the machine without humidifier for long lasting operation, There are machines that have a specific DC power cord to connect from battery to your machine and some machine designs such as Transcend and Z1 use a specific battery.

    Is there a maintenance schedule for my CPAP Machine?

    Contrary to what you may have been told by your local provider, maintenance is NOT required to be performed on the machine with the exception of changing the filters on a regular basis. Many providers will attempt to sell you maintenance packages for your equipment. Don't be fooled, be way of vendors who often try to up-sell you extra unnecessary things.

  • CPAP Humidifier FAQ

  • What is a Humidifier?

    When using a humidifier, it will add moisture to the filtered air by the CPAP machine, reducing that dry cotton mouth feeling. There are different types of humidifiers that can come with or without your CPAP machine. Listed below are the different types:

    • Integrated Humidifier : Integrated humidifier is used for a specific CPAP machine that will ONLY fit that machine
    • Built in Humidifier : Built in humidifier is designed as a part of the CPAP machine that CANNOT be removed from the CPAP machine
    • Heated Humidifiers : A heated humidifier uses heat to warm the water to add moisture to the air from the CPAP machine
    • Waterless Humidifiers: The waterless humidifier works by gathering moisture while you exhale and returning to your lungs upon inhalation. ResMed AirMini uses this to recycle humidity .

    Should I use special water in my humidifier?

    You should always use distilled water in your humidifier to prevent the buildup of mineral deposits on your water chamber. This will significantly prolong the life of you humidifier.

  • CPAP Mask FAQs

  • What causes dry mouth when you wake up?

    • Usually there are 2 possibilities, first the humidity in the humidifier may not be producing enough.
    • Second there may not be enough pressure keeping your mouth open causing the air to leak out, which can cause dry mouth.

    How do I know if the CPAP mask I want will work with my machine?

    All of the masks are standardized so that any mask will connect with any machine. However it has been said that with pressures over 12 cm of H2O, nasal pillow style masks may become uncomfortable for the user because of the high pressure being applied directly inside the nostrils.

    How do I clean my mask, tubing, water chambers?

    The best way to clean your mask is to use a product that we sell specifically designed for cleaning CPAP mask. This cleanser disinfects your mask without breaking down your mask cushion. Otherwise you can use a MILD soap that is NOT anti-bacterial. This is because the anti-bacterial soap will break down you mask cushion significantly faster. Tubing can be cleaned using a mild vinegar water solution (1 part vinegar, 3 parts water) and swishing is back and forth through your tubing. You can also use the Tube Cleaning Brush that we sell to assist you in the cleaning process. Water chambers can also be cleaned with the vinegar.

    Which CPAP mask is the right size for me?

    A general guide to choosing the correct CPAP mask
    • Nasal Mask: Having a triangle or pyramid shape, the nasal mask is the most widely used type of CPAP mask. This type of mask solely covers the nose and is for patients who are able to inhale and exhale well enough to sleep with a closed mouth
      • The usual construction of a nasal mask is a solid plastic type of frame that holds a soft silicone or gel-like cushion, which lies against the top lip, cheeks and bridge of the nose. A strap style headgear is used which can also be found with a forehead brace.
    • Nasal Pillow Mask: Being smaller in size and less obtrusive for CPAP users, the nasal pillow mask has become more popular over the last few years. The nasal pillow mask is a good alternative with patients who find a standard nasal mask to fit poorly or those who find a leak in the eye area. Nothing lays above the nose so those who have a shorter face or a narrow nose bridge will benefit most from the use of this mask. The typical construction of the nasal pillow mask is a multi-strap headgear that is attached to a frame which secures the soft silicone nasal pillow. Also some mask include a cradle which doesn’t enter the edge of the nostril, yet lies directly beneath the nostril
    • Full Face Mask: Covering both the nose and mouth, the full face mask is prescribed to patients who are mouth breathers. Some patients experiencing a dry mouth should also consider a full face mask. If you are experiencing an uncomfortable rubbing and soreness around the bridge of your nose maybe considering a total face mask would avoid further discomfort. Construction of this style mask includes a solid plastic type of frame that secures a soft inner cushion that rests directly on the face. The headgear is strapped and can include a forehead brace.

    Mask Sizing

    Currently there isn’t any specific standard for the sizing of CPAP masks. Sizing differs between all models of CPAP masks, even within manufacturers. The usual sizes of masks are petite, extra small, small, medium, large, and extra-large. Some manufacturers are starting to include a variety of cushion sizes within one mask package to help alleviate the issues sizing can bring up. In most cases the headgear included with a CPAP mask are one size fits most, while small or large headgear sizes are usually available if needed.

    Gauging the size of your face

    Manufacturers now offer sizing gauges for most of their mask products. These are very useful to use when determining the mask size. Although not always completely accurate because individuals have unique facial features, it is a great place to start.

    Mask Fit and Adjustment

    Upon choosing the mask size and style for your face, you will need to adjust it properly before sleep. While sitting upright on your bed, turn the machine on, and hold the mask against your face with the straps unfastened. Lie down in your normal sleeping position with your head on your pillow. Now gently and slowly pull the straps until you get a good seal, and then fasten the straps.

    When do I need to replace my CPAP Mask?

    In general, it is recommended to replace a masks cushion every 3 months and the complete mask every 6 months. A new and well-fitting mask will maximize the benefit of the CPAP treatment to all patients.

    Here are some signs it is time to replace your mask:

    1. The mask is not as tight as before or the seal is leaking air.
    2. Parts of the mask are worn out and are not in good shape.
    3. The construction of the mask, such as plastic or silicone begins to crack.
    4. The mask is deformed, causing leaking or discomfort.

    If your mask is newer, before you replace your mask, try to adjust the straps on the mask and attempt to fit the mask on differently. Most of the time this will fix the leaks which are the result of an improper fit. If the construction and seal of the mask are still in good shape and only parts are worn out, contact us @ to find out if it is possible to replace only the worn out parts. A lot of manufactures do provide replacement parts and provides a way to avoid unnecessary costs.

    Some CPAP users are reluctant to replace their old mask because they are afraid a new mask might not be as comfortable or that it takes time to for it to break in. Well, there are some great CPAP masks out there and companies are improving them all the time. If you do your homework and have a little patience, you may find a mask that you prefer over your old one.

    Here are some tips to help you find a new replacement mask:

    1. Find one that is optimized for comfort and is touted as highly seal-able so that the treatment is more effective.
    2. Try a well-fit and stable head gear which can be easily adjusted even when the mask is on the face.
    3. Head straps should be easily clipped-on and easy to remove.
    4. The airflow tube should be able to be rotated 360 degrees, so that it won't get in your way when you need to move your head around.
    5. The mask cushion should provide stability, comfort and will help seal from leaks.
    6. Make sure the tubing is able to be removed easily.
    7. Vents should disperse air very quietly and effectively, which means a good night’s sleep for you and your bed partner.
    8. A mask should be very convenient to use as far as adjusting, cleaning and wearing.
    9. Check to see if parts can be easily disassembled and replaced separately to help offset the cost of CPAP supplies.

    What’s the reason you take off your CPAP mask at night?

    • The pressure may not be enough and can make breathing hard for the patient. This can cause most people to stop breathing. By instinct most people feel uncomfortable and open their mouth and then an increased pressure blows out making you feel the need to take the mask off. During this time the patient may not be awake but in a light sleep, causing the user to find his/her mask off in the morning without recollection.
    • Also when you hold your breath for too long an increased amount of leaked air will come out and wake you up. This is not the machine however raising the maximum pressure setting or the minimum setting can help reduce the struggle.
    • You should seek professional help in changing pressure settings on your CPAP machine.

  • CPAP Machine Replacement

    CPAP machines do not necessarily have a shelf life, however in today's technologically fast paced world CPAP machines are constantly evolving. Keeping this in mind, your reaction and satisfaction of therapy will also change over time. It is very necessary to continually follow up with your sleep doctor and/or physician regularly to know where you are with your sleep apnea diagnosis.

    My last two CPAP machines seemed to be the same, why change?

    Sooner than you realize, the very CPAP machine you are using has been given a version update to perform certain functions and to update the internal software of the CPAP machine. This internal software, also known as an algorithm is used to interpret your sleep habits for data reports and for the machine to adjust on the fly to your therapy needs.

    So if they are updated so often, how do I know if I should replace my CPAP machine?

    As much as it is important to keep current on your sleep apnea therapy, it would not be cost effective to purchase a new machine when the newest released version is out. That being said, be sure to contact us at or your local DME for a side by side comparison and analysis to make sure your therapy is on the right track.

    So when is the best time to replace my CPAP?

    Medical insurance has a replacement time-line of 5 years, which may very well change soon due to the advancements that continue to evolve. At we recommend replacing your CPAP machine every 3 - 5 Years. Check out our CPAP machines selection and always feel free to contact us @ 1-866-936-3754 or email at [email protected] if you have any questions.

    CPAP Machine Filter Replacement

    Protecting the CPAP user from dust particles and other allergens, disposable filters for CPAP machines are the most cost effective and easiest way to improve your sleep apnea therapy. Each machine has its own unique filter fibers and are sized for the specific design of your machine.

    How do I know it's time to replace my filter?

    Check your filter every one to two days and look for an over-saturation of grey or brown coloring throughout the filter. This shows the sign of needing to be replaced. Look to our CPAP filter section for your CPAP machine replacements. Respshop recommends you swap out the disposable filters at least every three to six weeks.

    Machine Tubing Replacement

    CPAP tubing is the direct link from CPAP machine to CPAP mask user. As the air passes through the tubing, it can accumulate ambient bacteria that can accumulate in just a short period of time. Even by simply leaving tubing out during day time hours, dust, allergens and harmful bacteria accumulates.

    How do I avoid the bacteria from affecting my therapy?

    Maintaining a daily cleaning regimen is the first defense against the bacteria. One method of cleaning is to use a small tub, filled with warm water and a light detergent. Place the tubing in the water for a thorough rinse. For deeper cleaning pick up our innovative CPAP tubing brush . Use this tubing brush in combination with the above instructions for a more abrasive scrubbing motion. While cleaning your tube daily is great for upkeep, UN-removable bacteria will build over time and it is recommended you replace your tubing every 3 months.

    Humidifier H2O Tub Replacement

    While heated humidifiers aren't a required part of each CPAP users setup, the increased usage of humidifiers are apparent in today's sleep apnea culture. The water chamber inside the humidifier is a cleanable and replaceable component. It is highly suggested to use strictly distilled water for the tubs contents. The reason behind this is that minerals and calcium in tap or other water sources can create a film and/or mineral deposits that cannot be removed from the water tank. Calcium build up and minerals can lead to decreased effectiveness of therapy, causing your sleep apnea to suffer.

    My water chamber is dishwasher friendly, isn't this enough to prevent these issues?

    Yes, using the dishwasher will provide a longer life for the chamber however this does not completely resolve the long term conflict of calcium and minerals accumulating inside the chamber. It is recommended that your CPAP humidifier be changed every 6-12 months.

    Entire CPAP Mask Replacement

    CPAP masks are possibly the most important component of sleep apnea therapy as it directly connects the user to the CPAP machine. While inhaling/exhaling spreads germs throughout the mask components and tubing, each mask has the ability to be disassembled for a more thorough cleaning and the ability to swap out the individual mask parts. Replacing the cushion and headgear regularly is a great habit as it prevents you from breathing in harmful germs or bacteria.

    If I am swapping out the cushion and headgear, why should I buy a new entire mask?

    Keep in mind that over time all the components within the mask either wear out or accumulate harmful germs. Replacing the entire mask every 6 months will help achieve the highest quality of sleep apnea therapy.

    CPAP Mask Cushion Replacement

    Mask cushions are the most overlooked item that can lead to severe skin irritation, pneumonia and overall health. This piece touches your skin daily and most skin is very sensitive to the mask pressure and overall cleanliness. Health care professionals have continued to stress to our company that users need to be aware that the silicon and gels cushions today are not being replaced frequently enough. However when new cushions are replaced, most CPAP users immediately see less leaks, irritation and other allergies.

    But I have used my mask for 2 years and have no issues, duct tape and all?

    As much as we would like to make a CPAP mask last forever, the health risks are not worth the wait. We have seen very extreme cases of sores caused from the mask cushion contact leading to infection and then the end result is nearly irreversible skin disease. To prevent this make sure you sanitize your CPAP mask cushion daily and replace every 2 weeks.

    CPAP Mask Headgear Replacement

    Elastic and Velcro quickly lose their tightness and bond. You will notice mask leaks, frequent readjustment and therapy deteriorating while the headgear is near the end of its tenure. Not only will you experience therapy side effects, the oils, dirt and unsanitary build up over time can work its way into other issues.

    I don't mind tightening the mask when needed; I should be fine, right?

    Waking up in order to tighten the mask is similar to sleep apnea. Why compromise your therapy, when headgear replacement has so many benefits and only needs replacing every 3 months.
