CPAP Filter FAQS

When do I replace my CPAP filter?

If you’re using a disposable filter, change it like a furnace filter, every 3 months, but check it weekly for signs of wear and tear.


How do I know when to replace my CPAP filter?

Look for signs of dirt and debris. For example, you might notice a change in color. Dust and smoke can cause a white filter to go grey — you may see black particles on the filter. If this happens, change your filter to maintain maximum effectiveness.


Are CPAP filters universal?

No, different types of CPAP filters work with certain machines. Speak with one of our team or read the product description to find one compatible with your CPAP machine.
