HEPA Filters

HEPA filters are a type of media filter. It is made by randomly arranging fibers (usually fiberglass) into a mat. The mat is then folded and pleated to the desired size. In many air purifiers, air will go through several different layers of the mat. These types of filters are excellent for removing particles from the air. The particles removed are common allergens like pollen, dander, and dust.

These filters can remove 99.97% of particles as small as 0.3 microns. A micron is one millionth of a meter. For comparison, a hair on your head is about 80 microns. In order for these filters to work air must be forced through the filter so a strong fan is a must. This kind of filter will work great for allergy and asthma sufferers.

Activated Carbon

Activated carbon in nothing more than specially treated charcoal. After charcoal is created it is treated with chemicals or steam under high temperatures to activate it. This forms millions of tiny holes and greatly increases the surface area. This is what we want because the carbon is highly chemically reactive. A chemical reaction occurs between chemicals in the air and the carbon permanently bonding the chemicals to the carbon.

These filters are great at removing odors and chemicals from the air. They are a good choice for someone who needs smells removed from their house. A person with Multiple Chemical Sensitivities will also need an activated carbon filter to remove all the chemicals in the air.

Ionic Filters or Negative Ion Generators
