Masks Size Guide

CPAP filters help safely remove environmental particulates like dirt, dust and contaminants such as allergens, or bacteria so you can enjoy clean air during therapy. Select from standard or hypoallergenic filters.

Standard filters should be changed at regular intervals to ensure therapy air is filtered. Change frequently if you have house pets. 
Hypoallergenic filters are ultra-fine to provide additional filtration from airborne allergens. Recommended for users suffering from allergies.
