Here in the Treasure Valley area of Boise, Idaho, we live in what is called the high desert. We have good share of dust and allegens from trees and desert grasses and weeds. So, let's talk about HEPA filters. HEPA is an acronym for 'High Efficiency Particulate Air'. A true HEPA is a type of filter that removes at least 99.97% of particulates such as dust, animal dander, smoke, mold and other allergens that are 0.3 microns or larger, from the air. Most residential heating and cooling systems are not able to accommodate such filters because of there physical dimensions and increase in airflow resistance. There are bypass HEPA air cleaning systems that are ducted off the heating and cooling system but only clean approximately 30 percent of the air traveling through the duct work.
Portable air cleaners, are the type that treat the air in the immediate vicinity of the unit and are not intended for whole-house filtration. Here is why I discourage using them.
1. They treat the air only in the room they are being used in.
2. Separate units are required for each room.
3. Often they are noisy and obtrusive in living areas.
4. May not be as energy efficient due to the need for multiple units.
5. Require more frequent cleaning and maintenance. Filters need changed every
one to three months.
All of that being said, why not consider the best solution for your home and health? A WHOLE-HOME air cleaning system. I know that sounds expensive, but in reality, they are not. They can improve the efficiency of the central heating and cooling system by as much as 25% by trapping and removing harmful dust, dirt, dander and hair that would otherwise settle on your equipment.
They are designed to last as long as your heating and cooling system, and filters require changing anywhere from 1 to 2 years, or some can be cleaned and used for up t 10 years before changing. Read more of my blogs at
