Function & Filter Replacement

There are many variables to determining a precise filter life, such as the amount of pollution in your area. At Purar, we believe in sustainability and our mask is designed to be environmentally friendly without frequent disposal.

After purchasing the Purar Air Mask, you can change the inner filter whenever the current filter is damaged, deformed or dirty, or when you feel that the breathing resistance increases significantly during use. Our replaceable filters can last up to 100 hours on average, and we suggest changing the filter every second week or so for hygienic reasons.
