Routine maintenance of your HVAC system should include changing the air filter in your home regularly. There are different types of HVAC filters and when you know what you need, you can properly care for your furnace and air conditioner.

Different Types of HVAC Filters

Let’s go through the various HVAC filter types so you know how to choose the right one for your home.

Pleated Filters

Pleated filters are very common. These filters prevent dust from entering your HVAC system and trap particles and allergens such as dust mites and pet dander. Of the different types of HVAC filters, the disposable pleated filter is effective and economical.

There is a high-efficiency pleated filter, also. High-efficiency pleated filters are commonly found in hospitals due to their ability to trap even the finest particles, but they are expensive and not all HVAC systems are compatible for installation.

Basic pleated filters are essentially a step up from fiberglass filters; not bottom-of-the-barrel, but not high quality either. The good thing about being somewhere in the middle is that they are sufficient in many circumstances and cheap enough you can change every month or two to keep your air quality breathable.

Fiberglass Filters

Of the several different types of HVAC filters, fiberglass is the most common, least expensive, and least useful. These filters do little more than trap large particles from entering your HVAC system.

Disposable fiberglass filters are not generally good for people with asthma or allergies to use, as they really do nothing to actually help purify the air. These filters will help keep the HVAC system from becoming clogged but are not going to keep the air clear enough for anyone with respiratory sensitivities.

Electrostatic

Thankfully, one of the different types of HVAC filters is highly effective and won’t break the bank.

The disposable electrostatic filter combines cotton and paper fibers to create a static charge when in use. The charge attracts air particles like a magnet, which is fantastic for people with allergies or asthma symptoms.

There is also a permanent electrostatic filter which is washable and lasts up to eight years- great for people with pets or areas high in allergens.

  • Higher efficiency while still affordable
  • $40-$60 each

The type of HVAC filter you choose will determine how efficiently you can achieve cleaner air quality. It’s better to spend a little more money on a quality filter than to have household members suffering from allergies, asthma, or other respiratory distress.

So, how often should you change your air filter? Experts recommend at least every 3 months for an average household with no pets. If you have pets or family members with allergies, asthma, or other respiratory sensitivities, you should replace your air filter every 1-2 months.
