Foam CPAP Filter, Re-usable

Not sure what to think at this point. I found out that when I put a new one in the machine along with one of the little white filters, a new black filter turns that white one black within a few days. So whatever you do--always put a white one with it so you don't breathe any microscopic sponge particles into your lungs. This makes me wonder about the quality of the sponge material. Next time I want to buy them from someone else to compare this problem. Maybe they all do it, I don't know. However, I do know that the sponge that came with the machine didn't do that.

These filters are exactly as advertised, they are the correct size for the Phillips Respironic PR System One. They work just as well as other OEM filters I have used, and they price is even cheaper then my DME, even after 80% co-insurance! I recommend these if you are looking for a good price on filters for this CPAP model.

great product and good price, fast ship... the dimensions in the pic are wrong, is 1 3/4 long x 7/8 wide x 1/4 thick... I usually get mine from the VA but they have been slow.. so now I have a source..

Same filters available through Medicare providers at a much better price.

Same as the ones from the medical supply house at a fraction of the price.

I BOUGHT THESE BECAUSE THE SUPPLIER I HAD USED WAS TOO EXPENSIVE. THESE FIT PREFECTLY AND I CAN CHANGE THEM MONTHLY AND NOT HAVE TO WASH THEM ALL THE TIME.

These filters appear to be identical to those sold under the Respironics brand name...and are a bargain in comparison.

Don't waste your money on brand name filters. These do the job for a fraction of the price.
