Save on O2 CANADA Filters with this 5 pack bundle of individually sealed O2 Curve Filters!

The O2 Curve Electrostatic Filters (formerly known as O2 Commuter Filters) are charged with pockets of both negative and positive ions. They attract, trap and neutralize small particles. The O2 Curve filters are capable of blocking particles as small as 0.1 microns. They trap mechanical pollutants found in pollution as well as bacteria and diseases, and based on average use the filter can last up to 2 weeks.

Note: The filter goes inside your mask and needs to be changed at regular intervals depending on usage.

**Change filters weekly or every 2 weeks. If you don’t use it everyday, you can change after more than 2 weeks or once the side facing the shell starts to discolor or build up dust
