Changing out your air filter on a monthly basis can not only keep dust, allergens, and other harmful airborne particles out of the air, but it can also greatly decrease the cost of your electric bill because your HVAC unit won’t have to work as hard to cool or heat your home. By reducing dust, air filters also lessen the residency of dust mites in your carpet and upholstery, which is particularly important since dust mite droppings can also cause allergy and respiratory issues.

When selecting an air filter for your air duct, consider the dimensions of the space available. If you purchase a filter that is too small or too large, dust and allergens can pass through the cracks and clog your HVAC unit over time—not to mention put you and your family at risk for illness. For the different types of HVAC units, there are also different types of air filters. Below is a list of the best filters, arranged from least to most expensive.

Carbon Air Filters: As oxygen passes through a Carbon air filter, its pores expand and become highly absorbent. These pores are what catch fibers and particles, effectively barring them from leaking through to your central heating and air conditioner. In addition to trapping dust and dander, Carbon filters also absorb cigarette smoke and other unpleasant odors. A Carbon filter can be purchased for about $20 online.

Ionic Air Filters: These filters (also known as “ionizers”) depend on voltage to charge air molecules. This means that they use negatively charged ions (“anions”) to attract dust and allergen particles in the air, the same way static electricity from a balloon can attract your loose hairs. Ionic air filters are most commonly used in commercial air filtration. A standard filter like this will typically cost up to $25.

HEPA Air Filters: Also known as “high efficiency particulate absorbing” filters, HEPA filters are, as the name suggests, more absorbent and efficient at removing particles from the air than Ionic air filters in sensitive applications. These filters, comprised of fiberglass fiber mats that trap airborne particles, can eliminate up to 99.97% of dust and allergens. Depending on the size of the filter, HEPA filters range from $25 to $55 online.

UV Light Air Filters: These filters work by using a chemical reaction that involves titanium dioxide and UV light. This photochemical process effectively neutralizes any carbon-based organic compounds, such as mold or bacteria, that pass through the filter by allowing UV light to break them down. These air filters are especially desirable for establishments that rely on antiseptic environments, such as doctor’s offices or hospitals. UV Light filters can be anywhere between $50 and $80.

Remember that just because an air filter is “more effective” in some situations does not mean that it is the best air filter to use on your HVAC unit. Be sure to investigate the proper dimensions for the air filter and check to make sure you’re getting the right filter for your specific system.

Monthly replacements of your air filter can greatly reduce dust, allergens and dust mites in your home, so you and your family can breathe easily knowing that you live in a sanitary atmosphere. However, even with the added precaution of installing the proper air filters for your HVAC unit, you should also have your carpet cleaned regularly.
