Furnace filter types: - Fiberglass particle filter - These inexpensive
disposable filters stop large particles from entering the furnace and being sent through the ductwork into the house. They
do not help filter particles that worsen allergies etc.
- Passive electrostatic filter - These washable
filters use a static charge to attract particles. They filter smaller particles than the fiberglass filter but are only able
to block a minority of particles in the air.
- Pleated filter - An increase in the surface area of
the filter helps trap a larger particles by allowing a finer mesh pattern without interrupting air flow to the furnace.
- Electronic
filter - One of the most effective options that comes with a price. Electronic air filters are expensive costing
several hundred dollars but they do trap as much as 80-90% of airborne particles. If you are concerned about allergies or
illness this is a good choice for your home.
- HEPA filter - Traps more air particles than any other
filter but are typically only used in commercial buildings.
