Ultra Fine Filters are made by Sunset Healthcare and are applicable with select Philips Respironics CPAP and BiPAP machines. The filters are made of white fibers and are 1 3/4" inches long and 7/8" inches wide.
Most commonly used in homes with high pollen or dust particles as well as homes with pets. If neither one pertains to you, you can still benefit from the use of an Ultra Fine Filter as it will add filtration of room air prior to you breathing it through the machine.
The filters are disposable and are not meant for cleaning! If you happen to get the filter wet, dispose of it and use a new filter. These filters are meant to be replaced every 1-2 months depending on the need for replacement. You will typically see the filter change from white to slightly grey or even black. It is extremely important to change this filter and should be considered as important as your Home Furnace filter!
The Ultra Fine Filter always goes in first with the Tab up and then the pollen filter follows. Each filter has a tab so you can easily remove the filter from the back of the machine.
