Respironics Disposable Filter for M Series - 2pk

This 2-pack disposable filter is designed for Philips Respironics M Series, SleepEasy, and PR System One machines, offering fine particle filtration to help keep dust, tobacco smoke, and pollen particles out of the air your machine delivers.

Is This the Right Filter for You?

This is a fit if you own an M Series, SleepEasy, or PR System One machine and want fine-particle disposable filtration. If you'd prefer the tab-style handle for touch-free replacement, see the M Series Disposable Filter with Tab instead. If you'd rather clean and reuse a filter than replace it frequently, the Reusable Foam Filter is a lower-maintenance alternative.

Why Choose This Filter

Broad Machine Compatibility

Unlike some filters that are model-specific, this one covers three related machine families — M Series, SleepEasy, and PR System One — which simplifies stocking up if your household or clinic has more than one of these machines.

A First Line of Defense for Air Quality

This filter helps keep dust, tobacco smoke, and pollen particles out of the air path, supporting cleaner intake air alongside your regular mask and tubing cleaning routine.

Replacement Schedule

Replace this filter approximately every 2 weeks, or sooner if you notice visible damage or dirt buildup. It's a disposable, non-washable filter and should not be cleaned and reused like a foam filter.

Frequently Asked Questions

How often should I replace this filter?

Approximately every 2 weeks, or sooner if it looks dirty or damaged. (See the flag above — this figure comes from the site's own meta description rather than the original body copy, which stated 30 days; worth confirming the correct interval before relying on it.)

What's the difference between this and the tab version?

Both are disposable filters for the same machine families at the same price. The tab version adds a grip tab for touch-free removal and replacement.

Can I wash and reuse this filter?

No, this is a disposable, non-washable filter. See the Reusable Foam Filter if you'd prefer a washable option.

Does this fit my SleepEasy or PR System One machine?
