Description
Protects against 98.6% of 2.5 micron particles*
* University of Waterloo study conducted at 32 L / min and particle size range from 0.5 microns to 4.7 microns

Capable of filtering infectious droplets containing bacteria and viruses.
The O2 Curve uses a triboelectric charged filtration system, which consists of a hydrophobic outer shell that sandwiches a layer of melt blown filter medium. This filter system works both mechanically and electrostatically, and particles that are too small to be filtered physically are attracted to the charged filter, for improved filter efficiency and performance.
- Provides exceptional protection from airborne particles like dust, mold, viruses, bacteria, and allergens
- Medical grade silicone provides a weightless seal for unsurpassed comfort and a personal breathing space
- Adjustable silicone ear loops are soft, comfortable and won’t disturb your hairstyle

Cherise Jackson –
Makes wearing a mask much more enjoyable than surgical or kn95 masks that need to be replaced all the time. These filters are also much more cost effective and last longer in my experience.
