The HEPA tech for protecting your breath health.

Why choose HEPA?

High-Efficiency Particulate Air (HEPA) Filters are proven to be the most trusted filter technology on the market. The key to HEPA Filters is its tightly woven composition, making them an effective and safe solution to remove airborne particles that can aggravate:

Allergies
Virus
Athma attacks
Chemical sensitivity
Pollen
Settling dust
Mold growth
Pet-related allergies and odor
Smoke odor
Illnesses linked to viruses & bacteria
Long term respiratory health problems

How does HEPA work?
If you’ve ever seen heavy winds launch hundreds of ping pong balls into a rosebush, where most of them become embedded (who hasn’t?), you’ve essentially seen how a HEPA-flavored filter works. Just shrink the ping pong balls down into solid particulates, and shrink the rosebush branches down into microglass or synthetic fibers.


Material

HEPA is a flat, pleated sheet composed of millions of microscopic fiberglass threads, forming a complex maze which traps airborne particles.

Because particles 0.3 microns are the weakest point of the filter’s performance, a filter is only classified as HEPA if it removes 99.97% of particles that are 0.3 microns.




Three types of capture for HEPA

Interception

As particles flow by, they are attracted and stick to nearby HEPA filter fibers.

Impaction

Air flows smoothly around filter fibers, but particles collide and get embedded.

Diffusion

Microscopic particles move erratically, increasing the likelihood of being captured by interception or impaction.



What's the different between HEPA compare to HVAC filtration?

HEPA filters have the highest level of filtering. Most home HVAC systems are not designed to handle the strain of the high resistance filtering of a HEPA filter, so an HVAC filter with a tight weave may reduce air flow and ultimately lower air quality. HVAC filters come in different MERV ratings,but even the most efficient MERV-rated HVAC filter is less efficient than an HEPA air purifier. If HEPA filtration is required, we recommend an air purifier.
