The standard filter is included when purchasing a CPAP unit. Manufacturers recommend changing it every 6 months or less for a better protection of your respiratory system and the unit itself. Please do not use more than one filter at a time. Do not wash with water or soap.

Hypoallergenic filters are better suited to trap fine particles that can infiltrate your unit, and ultimately harm your respiratory system. These filter types are not included with the purchase of a CPAP unit, and can be added afterward to offer a better protection against different allergens found in the ambiant air. Manufacturers recommend changing them after 6 months of use or less. Never use more than one filter at a time. Do not wash with water or soap.
