Overview

Good therapy starts with clean air—and that means a clean filter. These Purdoux disposable filters are sized to fit perfectly in your ResMed device and help block dust, pollen, and airborne particles that could interfere with your sleep or your machine.

This 3-pack gives you about a month’s worth of filters if you change them every two weeks. If you have pets or smoke at home, you’ll want to swap them out even more often. It’s a small detail, but one that makes a big difference in how your machine performs and how you feel every morning.

Clean Filters, Better Sleep

These disposable filters are made to fit snugly into your AirSense 10, S9, AirCurve, or AirStart device. They help reduce dust, pollen, and other particles from entering the airflow so your machine can deliver cleaner air—and your therapy stays on track night after night.

Sized Right for ResMed Machines

No trimming or forcing into place—these filters are cut to match your ResMed device exactly. That tight fit helps block fine particles from slipping through and affecting airflow. It’s a simple swap that supports better breathing and extends the performance of your CPAP machine.

Helps Protect Your Airways

Filters don’t just keep the machine clean—they also protect your lungs. Swapping them regularly helps reduce exposure to airborne irritants like pet dander or smoke. Clean filters mean fewer chances for particles to circulate while you sleep, especially important if you have allergies or sensitive airways.

Easy Replacement Schedule

Each pack contains three filters—enough for around one month of regular use if changed every two weeks. If you have pets, smoke indoors, or notice discoloration sooner, it’s a good idea to replace them more often. It’s a small step that can make a noticeable difference.

Supports Your Machine’s Lifespan

A dirty filter can strain your CPAP device, reducing airflow and making it work harder than necessary. Replacing filters regularly helps the machine stay efficient and prevents buildup that could interfere with long-term performance.

Important Tips

  • Replace your filter every two weeks, or more often if you have pets or smoke at home.
  • Never reuse these disposable filters—they're single-use to ensure optimal filtration.
  • Clean the filter area with CPAP wipes before inserting a new one.
  • Use a CPAP cleaning machine to keep your device’s interior dust-free and working efficiently.
  • Always store unused filters in a clean, dry place to protect them from moisture and contamination.
  • A clogged or dirty filter can affect air pressure and reduce the effectiveness of your therapy.
  • Make sure the filter is properly aligned to avoid any air bypass or leaks.
  • Pair your filter maintenance with hose cleaning using a brush set to keep airflow clear.
  • Using distilled water in your humidifier can help reduce airborne particles reaching the filter.
  • Regular filter changes also help protect your CPAP motor from dust and extend the device’s life.
  • For a full routine, explore CPAP cleaning supplies that support healthy, consistent therapy.
  • A fresh filter makes a real difference in both machine performance and how rested you feel.

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)

How often should I replace my CPAP filter?

Disposable filters: Every 2-4 weeks or sooner if dirty. Reusable filters: Wash weekly and replace every 3-6 months.

Can I clean and reuse a disposable CPAP filter?

No, disposable filters are designed for one-time use and should be replaced, not cleaned.

What happens if I don’t change my CPAP filter?

A dirty filter can reduce air quality, block airflow, and strain the machine, potentially causing damage.

How do I know when my CPAP filter needs changing?

If you notice discoloration, dust buildup, a musty smell, or reduced airflow, it’s time to replace the filter.

Do CPAP filters help with allergies?

Yes, ultra-fine filters help trap allergens like pollen and dust mites, improving air quality for users with allergies.
