Reusable Black Foam Filters for Tranquility Quest, Tranquility Auto, Tranquility Bi-Level, Tranquility Quest Plus (2 Pack)

I am using them for my face masks... they fit in there very well. Not stuffy or hard to breathe and I feel more protected then a coffee filter which was recommended.

Perfect fit.

Thank you so much for being there when I needed you! The C-PAP filters are a perfect fit. Your fast responce time allowed me to get the sleep I needed.

Just what I needed. Fits prefectly. Fast delivery.

Filters fit perfectly. Thank you.

I was very happy to be able to get replacement filters for my Tranquility Quest C-PAP unit. The unit is no longer available and my local supplier said they couldn't get any replacement filters for it.

The filters fit perfectly and the hose is incredible. My other hose was kind of old and had plastic ends. The new hose has rubber ones which seem to seal much better. I have slept the all night since I installed it. The snuggle hose cover is great too (no more ruff hose) Wow!!. I was impressed with how quickly I recieved the merchandise. You folks are great. Keep up the good work. I don't need to shop anywhere else for my needs. Thank you, Len P.
