When it comes to your HVAC system’s air filter, it’s important to know your options well. Your filter can ultimately affect the energy efficiency and performance of the entire HVAC system, and can impact your indoor air quality as well. That said, choosing the right air filter for your home is essential. Here reputable HVAC company AAA Air Conditioning, Inc. discusses some of the factors you should consider when purchasing a filter.
Disposable or Reusable
Reusable or washable air filters usually cost more than disposable filters. However, since they can be reused multiple times, washable filters can reduce long-term costs and generally prove to be more cost-effective. The major drawback is that they require removal or disassembly, and you have to wash them thoroughly at least once a month. Moreover, you may have to turn your HVAC system off while cleaning the filter.
You’ll probably hear about MERV from your HVAC contractor since this is an essential feature to consider. MERV (minimum efficiency reporting value) ratings are basically used to measure the percentage of particles that an air filter can trap. It ranges from 1 to 20, with the higher number indicating better filter efficiency. MERV 9 to 12, specifically, are recommended if someone in your home has allergies or asthma. But for normal household use, air filters with MERV ratings of 5 to 8 are generally okay.
Other types of air filters include the following:
Flat Panel Filters – These are flat panels made of fibrous material like polyester and fiberglass. They’re the cheapest filters on the market, but they’re also the least efficient. They can only keep bigger particles such as pollen, dirt, pet hair and lint out of the HVAC system.
Pleated Filters – These have an accordion-like pattern, which gives them more particle-trapping surface without increasing the thickness of the filter. They’re usually made of a cotton-polyester blend or other synthetic material. Pleated filters do a good job of improving indoor air quality.
HEPA (High-Efficiency Particulate Air) Filters – These can capture 99.97% of passing particles that are 0.3 micrometers or larger in size. They’re generally effective at keeping indoor air clean, but they may slow down airflow in your home in the process.
