Although something as minor as an air filter may seem completely inconsequential to the overall functioning of your HVAC system, it might actually be the key, not just to keeping your energy costs in check, but also to increase the longevity of your air-conditioning and heating units. The filter is the first line of defense that your HVAC system has to limit the amount of dust and debris that makes its way into the system and can make your units work overtime and increase your energy bills. If you aren’t paying much attention to your HVAC filters, you might be doing your entire system a disservice.
There is a difference in the way that air filters work and what they do. Knowing what those differences are can help you to choose the right option for you and your system.
Fiberglass Filters
The most common type of air filter is the fiberglass filter. The most economical option, it is comprised of many layers of fiberglass material. The filters work by trapping the particles that are dense and stopping them from getting into the ductwork. The biggest disadvantage to fiberglass filters is that they can get clogged easily, and they aren’t as efficient at getting smaller particles as other alternatives.
Electrostatic Filters
Electrostatic filters are made from a type of material that emits an electrostatic charge to the air as it flows through them. The electrostatic charge works like a magnet to attract particles before they enter your HVAC system. They are generally more effective at catching particles than fiberglass filters, and are worth the extra cost for someone who has asthma or allergies. These types of filters need to be changed on a regular basis, just like their fiberglass counterparts, to keep your HVAC system working efficiently.
Electronic Filters
Electronic filters work by artificially generating an electrostatic charge to ionize the particles as they pass through the device, which can trap those particles that become airborne. These filters have to be plugged into a power source, and they have to be cleaned regularly instead of just replaced. They are usually considered the top-of-the-line in air filtration and are typically more expensive than other types of filters. The biggest advantage is that they can be washed instead of having to be replaced frequently.
Specialty Filters
There are other types of filters on the market that function as a good line of defense against particles getting into your ductwork. They work by preventing viruses and bacteria from getting into your system and being recirculated over and over again.
If you are ignoring your air filters, you may be doing your energy costs a huge disservice and putting undue wear and tear on your HVAC system. Not paying attention to your air filters and not changing them as needed might also be making your allergies worse and recirculating bacteria and viruses throughout your home. No matter which filters you choose, regular maintenance is critical to having a healthy and efficient HVAC system.
