PR System One REMStar Filters & Accessories

If you rely on a Philips Respironics PR System One REMStar CPAP or BiPAP machine, keeping it fitted with a fresh ultra fine filter is one of the simplest ways to protect both your device and the air you breathe. Over time, filters trap dust, pollen, and fine particulates — and a clogged or forgotten filter means your machine works harder and your airway gets less clean air. This collection focuses on the replacement filters that fit the System One REMStar line.

We carry the Sunset Healthcare Ultra Fine Filter (CF1009NT-2) and the Ultra Fine Filter for PR System One (CF1009NT-1), both in the no-tab design that seats correctly in the REMStar filter compartment. Ultra fine filters capture the smallest particles, so they're the layer most worth replacing on a regular schedule — many users swap them out roughly every two weeks, or sooner in dusty environments or during allergy season.

A common question: what's the difference between the tab and no-tab versions? The no-tab filters listed here are the standard fit for System One REMStar units, so if your original filter had no pull tab, these are the ones you want. They're disposable and not meant to be washed — replacing rather than rinsing keeps the ultra fine media working as intended.

Buying a few packs at once is the easiest way to stay ahead of your replacement routine and avoid running your machine on an old filter.
