CPAP filters are an important component of your CPAP machine and your sleep therapy. CPAP machines draw and compress ambient air, which is full of allergens, dust, and other particulates. CPAP machines have filtration systems that draw the air through the filter, removing airborne particles before the air is delivered to your lungs. Filters also protect and extend the lifetime of your CPAP machine by keeping particulates from accumulating in the machine. CPAP Filters need to be replaced regularly to prevent the possibility of more serious respiratory or sleep problems. Neglecting to clean and replace filters may cause complications such as respiratory infection due to poor air quality being pumped into the lungs.
