Heat Pump Filter in heating installation Gainesville, GA

We may not have seen snow yet, but many homeowners in northeast Georgia have already turned the furnace or heat pump on and are celebrating cooler weather. That means it’s time to change the furnace or heat pump filter. Have you ever noticed furnace filters get their own aisle at the home improvement store? Changing your heat pump filter is a simple thing you do to keep the air in your home healthy and your furnace running efficiently. Don’t let confusion over the different filter types prevent you from changing yours. We’re unraveling the mystery today and talking about the most common types of air filters you can buy for your heat pump.

Disposable Fiberglass Filters

They’re the most economical and do a fair job of preventing lint and other debris from clogging up your furnace. What they don’t do well is filter pollen, mold, bacteria, and tiny dust particles from the air. If you have allergy sufferers in your home, they’re not the best choice. You’ll also need to change them every 30 days.

Pleated Allergy Filters

Made from cotton or polyester paper, the pleated filter is also disposable but does a better job removing most allergens and dust particles from the air in your home. They’re a tad more expensive but usually give you about three months of use. Because they trap more dust particles, they may tax your HVAC system if you don’t change them often enough. Chat with your HVAC service company when they come out to take of your routine maintenance and see what they suggest about these filters.

Disposable Electrostatic Filters

For a price, you can install a washable electrostatic air filter, but for the budget-minded homeowner, why not use the disposable version? Full of self-charging fibers, an electrostatic filter attracts small particles and causes them to stick to the filter. This filter works great for households with kids and pets. They’re also suitable for a home with smokers.

HEPA Filters

There’s quite the buzz about High-Efficiency Particulate Air (HEPA) air filters. According to the EPA, HEPA filters can trap 99.97% of what you don’t want lingering in the air inside your home. Use caution when choosing a HEPA filter. True HEPA filters aren’t suitable for all residential furnace or heat pump systems. Contact someone qualified to do heating installation in Gainesville, GA, and ask if HEPA filters are compatible with your HVAC system.
