What’s included: Product pages show the exact filter type and count per pack (e.g., 2-pack, 6-pack).
Compatibility: Filters are device-specific—match your machine’s brand/series/model to the product’s Compatibility notes before checkout. Some devices use two filters (a reusable foam + a disposable ultra-fine).


Types:

  • Reusable foam/pollen – washable; captures larger particles.
  • Disposable ultra-fine/hypoallergenic – single-use; captures finer particulates.


Replacement cadence:

  • Disposable filters: every 2–4 weeks (or when discoloured).
  • Reusable foam: wash weekly and replace about every 1–3 months. Replace sooner if airflow drops or odour persists.


Care & safety: Never operate without a filter or with a wet filter. Use manufacturer-approved or equivalent filters to maintain performance.
Returns & warranty: For hygiene, opened filter packs are final sale; unopened may be returnable—see Returns.

Common Questions

How do I know which filter fits my CPAP?

Match your device brand/series/model and check the product’s Compatibility notes.

What’s the difference between standard and hypoallergenic filters?

“Standard” usually refers to foam; “hypoallergenic/ultra-fine” are disposable and capture smaller particles. Many users run both when the device supports it.

How often should I replace my CPAP filters?

Disposable ultra-fine: every 2–4 weeks or sooner if darkened/damaged. Reusable foam: wash weekly and replace every 1–3 months. Environment (dust, pets, smoking) may shorten intervals.

Can I wash and reuse my CPAP filter?

Only the foam/pollen filter is washable (mild soap, rinse well, air-dry completely). Do not wash disposable ultra-fine filters; replace them.
