ResMed AirMini Filters Hypoallergenic

The genuine ResMed AirMini Hypoallergenic Filter — high-efficiency capture of pollen, pet dander, mould spores, and fine dust. Designed exclusively for the ResMed AirMini travel CPAP. Available in 2-pack and 12-pack.

The ResMed AirMini Hypoallergenic Filter is the genuine high-efficiency replacement filter for the ResMed AirMini travel CPAP. Made from a hypoallergenic synthetic-fibre construction, it captures both fine and large airborne particles — pollen, pet dander, mould spores, and fine dust — making it ideal for allergy and asthma sufferers, or anyone travelling to areas with higher airborne particulate counts. Available in 2-pack (perfect as a backup for travel) and 12-pack (a year's supply at monthly replacement).

Key Features

• Hypoallergenic high-efficiency filtration: Captures both fine and large airborne particles — pollen, pet dander, mould spores, fine dust.
• AirMini-specific design: Sized and shaped exclusively for the ResMed AirMini — fits the small filter slot without modification.
• Disposable, latex-free: Replace rather than wash — slides into place in seconds with no tools required.
• Travel-ready packaging: Compact 2-pack ideal for tucking into the AirMini travel case as a spare.
• Genuine ResMed: Manufacturer-specified parts 38857 (2-pack) and 38858 (12-pack).

Compatibility

For use with the ResMed AirMini Travel CPAP only — including AirMini AutoSet and AirMini CPAP variants.

Not compatible with any other ResMed machine. AirSense 10, AirSense 11, AirCurve 10, AirCurve 11, AirStart 10, S9, and Lumis machines all use larger, differently-shaped filters that aren't interchangeable with this part. Check that the model name printed on your device reads "AirMini" before purchasing.

Standard or Hypoallergenic — Which Filter?

The AirMini Standard Filter is the default for everyday use in clean indoor environments. The hypoallergenic filter (this product) is worth the upgrade if:

• You have allergies, hay fever, asthma, or other respiratory sensitivities
• You travel to areas with higher pollen, dust, or smoke (rural areas, dry climates, peak hay-fever season)
• You're staying with friends or family who have pets
• You want a higher-filtration backup filter to keep in your travel case

Note from ResMed: Use of hypoallergenic filters can result in a small reduction in delivered pressure accuracy at high mask leak levels. The effect is minor and typically not noticeable in normal use, but it's worth being aware of if your therapy is leak-sensitive.

Replacement Schedule

Replace your AirMini filter approximately every month — the 12-pack is sized to last roughly a year of monthly replacement. Replace sooner if you notice visible discolouration, dirty patches, or a drop in airflow. After travelling to dustier or pollen-heavy environments, replace immediately on return as a precaution. Replace immediately if the filter has been exposed to liquids or visible debris.

Important — Do Not Wash

The hypoallergenic filter is disposable, not washable. Attempting to wash, rinse, or vacuum the filter damages the synthetic fibre matrix and reduces filtration effectiveness. Replace it on schedule rather than try to clean it.
