The Eson 2 Diffuser Cover is an eco-friendly washable and reusable filter 1 per pack. It is recommended to be washed in warm water at least once a week. Leave out to dry. Typically you will want to replace the filter once it looks to be worn, damanged, or dirty.
his is a good replacement Velcro strap that fits my Mirage Quattro CPAP mask. The thing I like the most about it was the cost vs CPAP stores. Actually the CPAP stores normally wonât sell the strap by itself and try to sell you a new mask for a couple of hundred of dollars.
