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.
HEPA stands for High Efficiency Particulate Air. These filters are designed to remove up to 99.97% of all airborne pollutants 0.3 microns or larger from the air that passes through the filter. These include tobacco smoke, household dust, and pollen.
The carbon filter is used as a pre filter to trap large particles. The carbon filter also helps in the reduction of room odors.
The carbon filter needs to be replaced every 3-6 months depending on usage, while the HEPA filter needs to be replaced every 12-18 months depending on usage.
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.
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.
The carbon filter helps reduce odors, such as smoking or cooking odors, and helps capture large airborne particulate.
