The disposable replacement filters are brand specific.
The length, width, and height are specific to these devices and allow the air to be properly filtrated by the machine. The machines pull from the room air when providing the user a positive airway pressure and the filter is the last line of defense for air pollutants.
Two Types of filters:
Standard filters are typically made from basic materials that capture larger particles, such as dust or dirt. While they provide adequate filtration, they are not designed to filter out smaller allergens or provide the same level of protection for people with allergies or sensitivities. Packaging is 2 filters per pack.
Hypoallergenic CPAP Filters: These filters are made from materials designed to trap smaller particles, such as dust, pollen, pet dander, and other allergens. They are specifically created to be gentler on sensitive skin and to minimize allergic reactions. Hypoallergenic filters are ideal for individuals with allergies or respiratory conditions like asthma. Packaginf is 2 filters per pack.
The replacement of the filters regularly also ensures the user is being provided with the best quality of air possible.
