\nWith any forced-air HVAC system, air filters play a key role. Thus, it\u2019s important to do more than just grab the first filter you see off the store shelf. Yes, there are different types available and getting familiar with them can help you identify what you need to make a smart choice.<\/p>\n
This type of filter is probably what you\u2019re most familiar with. These are the inexpensive, disposable options that are widely available in home-improvement retailers and even grocery stores. Fiberglass or synthetic filters are relatively efficient \u2013 catching up to 80 percent of particles that are 50 microns and larger. They can effectively minimize the buildup of dust and dirt on heat exchangers, fan motors and other surfaces of your HVAC system. <\/p>\n
Made from higher quality material, polyester filters trap and remove 80 to 95% of particles 5 microns or larger. With their greater effectiveness comes a higher price. Expect to pay approximately four times more for a polyester filter than a standard fiberglass\/synthetic filter. <\/p>\n
For even greater efficiency, choose a pleated filter that traps particulates 0.3 micron in size, including bacteria and viruses. Pleated filters also last longer than fiberglass\/synthetic filters. <\/p>\n
Electrostatic filters leverage the innovation of self-charging fibers to attract and remove particles from your air. Both disposable and washable electrostatic filters are available. <\/p>\n
High efficiency particulate air (HEPA) filters offer high filtration capabilities, capturing 99% of particles 0.3 microns or larger. It\u2019s important to consider that these filters are excellent at removing indoor pollutants and creating an easier-to-breath-in household environment. However, they can reduce your HVAC system\u2019s air flow, resulting in higher utility costs.<\/p>\n
Along with type, you also need to consider size when it comes to HVAC filters. You\u2019ll want to choose one that fits into the filter cabinet correctly to ensure there are no airflow obstructions that could hinder system performance. The most common sizes are:<\/p>\n
10 X 20, 14 X 20, 16 X 24, 18 X 30, 12 X 12, 14 X 24, 16 X 25, 20 X 20, 12 X 20, 14 X 25, 18 X 18, 20 X 24, 12 X 24, 14 X 30, 18 X 20, 20 X 25, 12 X 30, 15 X 20, 18 X 24, 20 X 30, 12 X 36, 16 X 20, 18 X 25, 4 X 24 and 25 X 25<\/p>\n
The importance of changing HVAC filters on a regular basis cannot be overstated. Over time, filters become clogged with pollutants \u2013 particularly here in Arizona. Forgetting to change your filter can cause costly airflow obstructions and can even damage your system. Stick to a set schedule of replacing or cleaning your HVAC filter at least once a month.<\/p>\n
