44PCS Premium Filters for Airsense 10, HEPA Filters for Airsense 10, IBEET Supplies Filters for RSM 10, S9/S10

I bought these HEPA filters for use in my ResMed AirSense 11 CPAP machine. They arrive nicely boxed and wrapped in resealable plastic. They are visibly thicker than the standard filter but fit the machine perfectly and seem to filter air just fine. Using these is like having your own personal air purifier. And they are so inexpensive that it’s worth changing them every week. A box of these will easily last a year or longer and cost far less than the less effective standard filter. Just remember to install them with the smooth side facing the machine.

It is a nice thick filter. Got here quickly and a great price

I have a ResMed AirSense 11 CPAP machine. These filters are the perfect size for my machine. I change filters once or twice a month.GREAT PRODUCTGREAT PRICE $$

These filters are inexpensive enough that I can replace the CPAP air filter more frequently and breath clean(er) air. It would seem however that due to their higher density than filters normally supplied with my device, the CPAP motor has to work harder to suck in air. This might lead to premature wear and tear and a need for more frequent replacement of your CPAP machine.

Works well. Would definitely purchase again.

they seem to work

Perfect size. Great quality. Fits ResAir 11.

Not only are these a perfect replacement for my Airsense 11 Cpap, but they are many times cheaper than my usual supplier.
