F&P Eson 2 Diffuser
This diffuser is a filter part for the Eson 2 nasal CPAP mask. The filter reduces noise and draft and is washable. The diffuser clips over the air vent on the mask elbow.
I like to order extras of these to have on hand. Since they changed the design of my mask I have to buy these instead of the less expensive filters. I like ordering from Respshop, they always have the items I'm looking for in stock.
