CPAP Filters

Frequently replacing your CPAP filter improves your sleep therapy and helps you stay healthy. During the months of spring, pollen and dust can easily settle into a Bi-Pap or CPAP machine, clogging up the machine and preventing it from working to its best ability. Filters for CPAP machines also help to prevent from inhaling harmful . . . particles from tobacco smoke into your respiratory system at night.

When Should You Replace CPAP Filters?

When to replace filters differ with each individual and CPAP machine but in general, it is best practice to change your CPAP machine filters at least once a month. Patients who are sensitive to dust, pollen and those living with pets may find that replacing their filter more often provides them with a higher level of comfort during therapy.

May of our CPAP filters include three or six units per package, making sure you always have a replacement filter on hand when you need it. Our selection also includes both washable, foam filters and disposable ones for certain machines.
