Philips Respironics DreamStation Ultra Fine Filter - 6 pack

Filters are specific to each machine model, so you'll need the one made for your machine — an AirSense 10 filter won't fit a DreamStation, for example. Check your machine model against this product's listing, or ask our team and we'll confirm the right filter and how many you'll need.

As a general guide, replace disposable filters monthly, or sooner if you have pets, dust or hay fever. Reusable filters should be rinsed weekly and replaced every 6 months. A clogged filter makes the machine work harder and can affect air quality, so it's one of the cheapest and easiest parts to stay on top of.

Disposable filters are fine-particle filters you replace rather than clean — they trap smaller particles and pollen. Reusable filters are a coarser foam you rinse and re-use until they wear out. Many machines use one or both. If you have allergies, a hypoallergenic disposable filter is worth considering, and we stock both types for most machines.

Filters sit in a slot on the side or back of the machine and slide out by hand — no tools needed. Slide the old one out, slide the new one in the same way round, and you're done. Check your machine's guide or this listing for the exact location if you're unsure.
