Everything you need to know about the Filter

High-Quality Air Filtration

The ResMed AirSense 11 & AirCurve 11 Standard Filter keeps dust, dirt, and other particles out of the air you breathe during your CPAP therapy. It’s a small but important piece that helps ensure you’re getting clean, fresh air throughout the night.

Protects Your CPAP Machine

Keeping your filter clean isn't just about better air for you—it's also about taking care of your CPAP machine. By blocking dirt and debris, the filter helps prevent wear and tear on your device, keeping it running smoothly for longer.

Easy Replacement

Replacing your filter is simple. Just take out the old one, check for any dust or damage, and pop in a new one. It's an easy task that helps keep your CPAP working its best without any fuss.

Captures Fine Particles

The filter is made from polyester fiber material designed to catch small airborne particles like dust, dirt, and pollen. This helps reduce what gets into your machine and improves the overall air quality of your therapy.

Protects Your Device

Using a filter prevents buildup inside the machine. It keeps internal parts cleaner for longer and helps avoid blockages or unnecessary wear over time.

Fits AirSense 11 and AirCurve 11

This filter is shaped specifically for the ResMed AirSense 11 and AirCurve 11 models. It slides easily into place and sits flush inside the filter slot without any gaps.

Simple to Replace

Swapping out the filter takes just a few seconds—no tools or instructions needed. Check it weekly and replace it every two weeks or sooner if it looks dirty.

Available in Multipacks

Filters are sold in packs of 3 or 6, so you can stock up in advance. Keeping extras on hand makes it easier to stay on top of regular maintenance without running out unexpectedly.

Supports Better Breathing

Because all the air you inhale during therapy passes through this filter, changing it regularly ensures you’re getting the cleanest air possible while keeping the machine efficient.

Important Tips

Compatible only with ResMed AirSense 11 and AirCurve 11 machines.
Replace the filter every 2 weeks, or sooner if visibly dirty, to maintain airflow and performance.
Check your filter weekly if you have pets, smoke, or live in a dusty environment.
Do not wash or reuse the filter—these are single-use only.
Changing the filter regularly helps reduce allergens like dust and pollen during therapy.
Make sure the filter is inserted flush and fully seated in the machine to avoid airflow gaps.
For better results, pair with the ClimateLineAir Heated Tube and humidifier to reduce dryness.

What do CPAP filters do?

CPAP filters trap dust, allergens, and airborne particles, preventing them from entering the machine and your airways.

Are all CPAP filters the same?

No, there are two main types: - Disposable filters (made of paper or synthetic fibers, replaced every 2-4 weeks) - Reusable filters (washable foam filters, replaced every 3-6 months)
