Generic Outlet Bacteria Filter (10 Pack)

Can't judge it since I haven't used it yet.

Haven't needed to use yet

The filter gives me a less congested restful night's sleep than before I added the filter.

Even though it's a bit bulky at 2 1/2" in diameter (very good idea for airflow), one end slides nicely... onto my Philips Dreamstation machine at the base hose output where it is totally out of my way when I sleep (NOTE: this will NOT fit if you use the heated hose). Then the hose end simply slips over the other end. It is impossible to put it on "backward". I am especially happy to have this filter in place since my machine is under recall due to the soundproofing material possibly sloughing off (https://www.usa.philips.com/healthcare/e/sleep/communications/src-update), but my doctor recommends continuing my use of this machine while waiting for Philips to correct their problem. I sleep more securely with this in place to keep any little particles from entering my lungs, and I may contunue using these filters even with a new machine. more...

nice idea but if you use a heated hose to keep humidity from condensing in the tube, you have to... attach this at the end close to your face and unless you use one of the masks with air input on top of your head its not very comfortable. more...

I have filters in my APAP machine but this in-line filter needs to be replaced every month. So much for... no outlet bacteria filter. I RECOMMEND FOR EVERYONE. more...

Have been using these on discharge of my recalled PR DreamStation ASV at the advise of my doctor. Humidifier... setting of 3 or 4; Pressure setting of 10.5. No restriction of flow issues. No humidity in the filter issues. One month and the amount of "grey matter" removal is outstanding. Could not be happier unless Medicare gives me a new CPAP machine. That ain't gonna' happen since my Dreamstation was only six months old when it was recalled. Here's hoping my Dr. knows what's ok & what's not. Thanks to cpap.com I can still afford to sleep more...

I've been using these filters to give my CPAP "extra filtering" while in use. While the machine's "basic" filters... do a decent job, these in-line filters capture "The Little Bits" that make it past the Main Filters. I periodically examine the filter surface and, when it's "gray" , it's time to replace the filter. In short, if you live in an area with lots of "particulate" air pollution, you'll do yourself a big favor by adding these in-line filters to your CPAP hose! more...

Too soon to tell (only been using it for 5 days). Besides which, I have no equipment or other... tests to tell if there are dangerous bacteria present, much less whether the filter is stopping any. more...

Now that I can change out my Bacteria Filter more often then my Medical Insurance allows I am Not only... Breathing better I am sleeping better too. worth every dime I paid for it. more...

Can tell in my dusty home when I use this and when I dont. Especially during pollen in spring and... fall. more...

I HAVE BEEN USING THESE FILTERS FOR A FEW YEARS NOW AND CHANGE THEM OUT TWO TIMES A MONTH. ... IT IS AMAZING WHAT IS FILTERED OUT IN TWO WEEKS. I WOULD NOT THINK OF USING MY CPAP WITHOUT THEM. THEY ARE A 10 IN MY BOOK. more...
