Quick answer: This is the genuine ResMed standard disposable filter for the S8 series (including S8 II models) CPAP/BiLevel machines — the blue/white felt filter that traps dust, pollen, and debris before air enters the machine. It's a disposable filter, replaced about every 30 days (or sooner if soiled). It also fits S7-series and C-Series Tango machines. Keeping a clean filter protects both your air quality and the machine. Sold in multi-packs. No prescription required.
What's included
- ResMed standard disposable filter(s) — pack quantity as selected (e.g. 1/ 2 / 6 / 12 / 50)
About this part
The air filter is the first line of defense for both your therapy air and your machine. This standard disposable filter is a thin blue/white felt insert that sits in the machine's filter compartment:
- Traps dust, pollen, and debris — cleaner air into the machine and to you.
- Protects the machine — a clogged or missing filter lets debris into the blower, which can shorten the machine's life or cause failure.
- Disposable — replace it about every 30 days, or sooner if it looks dirty or discolored (don't wash and reuse standard filters — that's for reusable foam filters).
- Standard vs hypoallergenic — this is the standard filter (basic particle filtration). A hypoallergenic version is also available for finer filtration if you have allergies.
Compatibility
Fits a wide range of older ResMed machines:
- All S8-series CPAP/BiLevel — S8 Compact, S8 Escape / Escape II, S8 Elite / Elite II, S8 AutoSet Vantage / AutoSet II, S8 VPAP S / ST / Auto / Auto 25
- All S7-series CPAP/BiLevel
- C-Series Tango
Note: this filter is for the S8/S7/Tango generation. The newer S9 and AirSense/AirCurve 10 & 11 machines use different filters — this one won't fit those.

Frequently asked questions
Which machines does it fit? All ResMed S8-series (including S8 II models), all S7-series, and C-Series Tango machines. It does not fit the S9 or AirSense/AirCurve 10 & 11 (those use different filters).
How often should I replace it? About every 30 days, or sooner if it looks dirty or discolored.
Can I wash and reuse it? No — standard disposable filters should be replaced, not washed. (Reusable foam filters are a different type.)
What's the difference from the hypoallergenic filter? This standard filter provides basic particle filtration. The hypoallergenic version offers finer filtration — a better choice if you have allergies or asthma.

Can I get it delivered in Brooklyn or shipped nationwide? Yes — Task Supply Corp offers USPS shipping throughout the continental U.S., plus local pickup and delivery in Brooklyn and all five boroughs of New York City.
