Disposable CPAP replacement filters are a highly popular kind of filter and are typically constructed of fine mesh material. If you have allergies or other sensitivities and are looking for the easiest option for maintaining your machine, disposable filters may be a good choice as reusable filters require some maintenance: ☆ Disposable, replace after 60 days ☆ Compatible with ResMed, Philips & Others Brand CPAP Machines. What is a CPAP filter? In most CPAP machines, at least one disposable filter is provided. Made of thin paper or paper-like material, it is electrostatically charged, which helps attract and catch the tiniest particles. The non-disposable filter, on the other hand, is made from absorbent foam and located at the back of the APAP machine.
