These CPAP filters are used to capture large particulate matter such as dirt or hair. These should be rinsed clean as needed depending upon your environmental conditions. The reusable CPAP filter needs to be replaced once the foam begins to deteriorate.
Glad to find a supplier of filters for my 18 yr old CPAP

"I was glad I was able to find a supplier of these filters for my 18-year-old Healthdyne 7000 CPAP machine and they fit perfectly. Could be priced better than $9.99 per pair of filters + $7 S&H, though."
Great
