Importance of Changing your Furnace Filter
The Environmental Protective Agency (EPA) states that indoor air is more polluted than outdoor air. In order to reduce indoor air pollution and improved operating environment, a good quality air/furnace filter is necessary for your heating and air cooling system. Consequently, an efficient system reduces energy costs, repair bills, and can prolong the life of your heating and cooling equipment.
Your furnace filter should be checked monthly. Typically, most manufacturerers recommend changing the filter every 3-6 months. Time between replacement is dependent on many factors. This can include the quality of the filter, time of year, presence of pets, allergy considerations, operation cycle of hvac equipment. Often, simply looking at the filter can indicate whether it needs to be changed.
There are several types of furnace filters available that differ in price, such as pre-cut media air filter pads, pleated furnace filters, electrostatic air filters, HVAC filters, and activated carbon air filters. The least expensive are fiberglass panel filters, and can be easily found at most hardware or big box stores. They are entry level and are considered monthly "throw-away" filters.
A step up from the basic filter is a disposable pleated paper filter, which will remove smaller particles like dust, pet dander, and pollen. These filters are more expensive but will last from three to six months before needing to replace them.
The most expensive filters are reusable electrostatic filters, which are designed to trap smoke and smaller airborne particles. They are rinsed clean with a garden hose, as needed. These filters can be reused for several years if properly maintained.
Some filters—in both disposable and reusable varieties—are rated as “antimicrobial” or “high efficiency particulate air” (HEPA) and are specially treated to trap microorganisms, including bacteria, mildew, fungus, mold, yeast and algae. If someone in your family has allergies, it may be worth investing in this filter type.
Changing the furnace filter is a fairly easy task. Consult your manual for proper procedure, but typically the process is as follows: turn off the furnace; locate the service panel and remove; slide out the existing filter (located near the intake/outtake blower fan); slide in a new filter and turn the furnace back on.
