CPAP Filters

CPAP filters are essential accessories designed to purify the air drawn into the CPAP machine before it is delivered to the user during sleep. They help protect the airways and maintain optimal device performance.

A clean CPAP filter improves air quality, reduces internal device contamination and supports effective, comfortable therapy.

What is a CPAP filter used for?

A CPAP filter traps dust, particles and allergens present in ambient air. It protects both the user (cleaner inhaled air) and the CPAP device (less internal buildup).

Using a properly maintained filter is especially important for people with allergies, dusty environments or pets at home.

What types of CPAP filters are available?

Depending on the brand and model, CPAP filters typically include:

• standard filters (foam or fiber): basic particle protection,
• fine filters (ultra-fine): enhanced filtration of small particles,
• hypoallergenic filters: recommended for sensitive or allergic users.

How often should CPAP filters be replaced?

Replacement frequency depends on the filter type, the environment and manufacturer recommendations. Regular replacement helps maintain good air quality and optimal device performance.

• Disposable filters: replace regularly based on use and condition.
• Reusable filters: clean as recommended and replace when worn.

A filter that appears grey, dark or clogged should be replaced immediately.

How to choose the right CPAP filter?

When selecting a CPAP filter, it is important to check:

• compatibility with the CPAP brand and model,
• desired filtration level (standard, fine or hypoallergenic),
• exact filter dimensions,
• personal needs (allergies, dust exposure, pets).

Using an incompatible filter may reduce device performance and compromise therapy effectiveness.

Frequently asked questions about CPAP filters

What happens if I do not replace my CPAP filter?
A dirty filter can reduce airflow, increase device wear and lower the quality of the air you breathe.

Can CPAP filters help with allergies?
Yes. Fine or hypoallergenic filters may improve comfort for sensitive users by reducing exposure to airborne allergens.

Can I wash my CPAP filter?
This depends on the filter type. Some filters are reusable and washable, while others are disposable and must be replaced.
