Micro Disk Filter for Respironics EverFlo Oxygen Concentrator - Set of FIVE (5)

I don’t know that much about the filter unit on the machine, I’ve changed that at suggested intervals and have HEPA filters throughout the house. But- if you are using an O2 concentration, well, we have issues with our lungs. More filtration can’t hurt. It doesn’t slow the 02 flow and is just one more way to ensure you are getting the cleanest O2 possible for sensitive lungs.Best to all !

Description says they're individually wrapped. Received a box of loose filters. How would you know they're even new? They're bacteria filters which should come sealed from the manufacturing facility. Now going through the process of trying to get my money back since they're not returnable.

I have added one in the output of my concentrator (because the vendor doesn't change the unit's filters often).I used a short section of hose intended for attaching a humidifier.(Note: you can not just cut the air tubing and push the ends on to the filter. There is enough back pressure that it won't get a good enough seal and it will leak. You need a hose end fitting on each side of the filter.)

The item received does not match the item pictured in the listing. The ones I received have thinner male ends that go in the hose and do not have the white casing around the filter. No returns either, so if your looking for what is pictured don't waste your money like I did.

happy

Perfect replacement.

Just needs a little more packing around it next time.People were very helpful
