Types of Filters

What is a True HEPA filter?

HEPA stands for High Efficiency Particulate Air. A true HEPA filter is rated to remove 99.97% of all particles that are 0.3 microns in size or larger.  A micron, also known as a micrometer is one millionth of a meter.  As a reference point a human hair is approximately 60 microns in diameter and a grain of pollen is 5 microns.

What is washable foam filter?

Washable foam helps capture larger particles and can be easily cleaned. Simply remove the foam filter from your machine and wash it in warm, soapy water. Rinse and drip-dry the foam thoroughly before replacing it.

What is an ULPA filter?

ULPA, also known as Ultra-HEPA, filters are designed to trap up to 99.999% of all airborne particles 0.3 microns or smaller from the air that passes through the filter. These include tobacco smoke, household dust, and pollen.

What is a Carbon filter?

Carbon filters capture larger particles and help reduce unpleasant odors.

What is an Electrostatic Filter?

Electrostatic filters use static electricity. They have a static charge, which causes airborne particles to cling to the filter, just like static charged clothing sticks together.
