it works

I’m not a respiratory technician. I’m a patient that depends on an oxygen concentrator to provide me with a steady supply of O2 to my bi-Pap machine all night long. There is an air filter in my concentrator and this fit very nicely. I believe it is working well as my O2 flow is as it should be.

This item is physically the exact size of the manufactures filter including the location of ports. Where this filter goes beyond the manufacturers filter is this one has a clear cover which allows you to see the condition (dirt), of the filter material.Looking into the filter housing, the filtering layers of the item shows multiple layers. The more layers the better the filtration. It is unknown if the manufacturers filter is constructed in the same manner because the manufacturers filter has a solid color cover.I highly recommend this filter due to its "user friendly" design, ease of replacing the filter and reasonable cost.

Repeat purchase. Works well in my Everflo.

Purchased unit is light transparent blue in color which allows one to see how dirty. Pic is of original grey unit after > 1000 hours of use indooors but user started to complain of odor or heat. So after installing new clear unit, I tore apart the unit and too a pic of pulled apart filter ' paper' both sides and left part near outlet in place. Notice black-dark side is near outlet, filter side is sort of grey, back side is white. Not shown is 1/4 inch foam pad paper filter sits on with small cutout to allow room inlet air from top to go thru filter to reach exit at bottom. Foam is mainly a spacer and not a filter.

I could have ordered a filter from my provider and my insurance would have paid for it, but when I do that the oxygen equippent rep has to come in my home and install it himself. I do not want anyone coming in my home during the coronavirus pandemic so I took a chance and ordered this one. I had read a few other reviews that said this filter didn't fit quite right. But the one I got was perfect. It took less than a minute to install, the fit was exact and I'm now satisfied that my Everflo Oxygen concentrator is working a top efficiency. It was well worth the low cost.
