Sterra Mars™ True HEPA-13 Filter (3-in-1)

This layer uses a filter fabric to effectively sieve out the largest particles from the air—such as hair, dust, lint, and animal fur.

This powerful, medical-grade True HEPA-13 filter effectively gets rid of micron particles in the air.

It traps up to 99.97% of all airborne contaminants including viruses and bacteria that are 0.3 μm in diameter.

In addition, it blocks allergens such as pollen, animal dander, dust mite droppings, and more to keep you and your family protected, healthy, and safe.

These extremely porous pieces of charcoal that come in a granular or powdered block form absorbs air contaminants.

So it neutralizes odors in the air you don't want to inhale such as tobacco smoke, foul smell from pets, cooking smells, etc.
