Philips | Ultra-Fine Filters (White) CPAPs, 6/pk | PR System One/M Series

The Philips Ultra-Fine Filters for my cpap were shipped to me fast with no issues. The filters work great on my cpap.

I'm always having trouble trying to get the filters to fit properly, even when they're supposed to fit my machine. These fit perfectly. No struggling, no trimming with scissors. They just drop right in! Great.

Thank you! So quick delivery! Great original filters, perfect package. Everything as expected.

I'm very happy with your service and i will do business again, I'm very happy with you, thanks.

Have been ordering these for my dad's machine. Always great experience.

Perfect fit. Catches fine particles that come through the foam filter resulting in cleaner air being forced into my nostrils.

Very easy to use and change the dirty filters. It is a good price-worth ratio. Recommend to get more at once.

Backup for Phillips fine filter. They are on sale nearly half price grab some for your stock.

It is good for maintainers purposes. Thanks, Respshop.

Always love free items, Thank you for supplying extra filters for my machine.

The picture does not do them justice they look better. They filter great. with my lungs being so bad and the area that I live being so dusty with the wind blowing most of the time. ( high plains ) These filters are very good I would suggest buying some extra they work so well. I have to change mine every two to three weeks.

For years I had been using the washable gray sponge filter only, but after talking to RespShop staff (they are very helpful), they recommended adding this pollen pre-filter to help with my allergies. I have noticed using this additional filter has made quite a difference for me, and I have not noticed any air restrictions at all from adding this extra filter. I will continue to use these filters, I just wish I had started using them sooner!

Great filter, provide double protection while it is working together with the black washable pollen filter. When I do a change of a filter, I found dusts filtered on the surface. I know I got protected.

Good Filters! And very good, you get some for free! Look FREE Gifts in the navigation bar on the left. I liked it also, that you can you use the Filters from my old machine in my current machine, too. Good compatibility!

Very hard filter to find. I'm glad you have them. Filters out all the bad stuff and keeps my machine clean.

Very good filter. When we have the windows open tat night the filter is black in a week....know it is filtering out the dirt from getting I to the machine as well as my lungs!

Great filter which double ensure the air is filtered for your health and your equipment is protected as well,make sure you change it max by 3 month.

Great filter. Know it is doing its job, you can see the dirt in it when it needs changed.

Great filter! Always performs well, change it about once a month unless we have our window open, then it is about once a week as we live on a gravel road.

Good filter, I know it is getting the dust and dirt out of the air before it passes into the machine (and my lungs) because it shows the dirt --then I know it is time to change it.
