Air filters help improve your indoor air quality by trapping unwanted contaminants and allergens from the air that your air conditioner circulates and cools. They require regular replacements to keep the air within your home clean. Here are three factors to consider when choosing an air filter for your HVAC system in Mercersburg, PA.
1. Type and Material of Filter
Different filters meet specific needs based on the kind of targeted pollutants. Also, the type of material determines its durability and filtration capabilities. Common air filter types include:
- Electrostatic filters
- Standard fiberglass or pleated filters
- Electronic filters
- Carbon filters
- Washable filters
Electrostatic filters are ideal for people with allergic reactions to dust, pet dander or pollen. On the other hand, carbon filters work best for poorly ventilated spaces with bad odors.
A standard fiberglass filter is a low-cost option with a trade-off of relatively low prices. Pleated filters are a better alternative to flat fiberglass filters but cost more. Generally, pleated filters are 4-inch thick, making them more durable than fiberglass.
The most expensive options are the washable air filters. Typically, the filters use polypropylene material to allow regular cleaning. In contrast, you should throw away fiberglass filters upon replacement.
Your selection should fit your heating and cooling system to yield the best results. You may want to refer to the manufacturer’s manual to see the dimensions and recommended filter type for optimal performance. Removing the existing filter and taking its measurements is an alternative if you lose your manual.
3. Efficiency and Performance
Each filter varies in its ability to trap particles from the surrounding air, measured by the minimum efficiency reporting value (MERV). A higher MERV rating translates to better filtration abilities. Keep in mind, though, that filters with the highest MERV ratings available belong in healthcare and commercial facilities rather than in your home. Home systems are not strong enough to pull air through these filters or HEPA filters.
