Choosing the Right Air Filter for Your HVAC System Makes a Real Difference

Air filters are an essential part of the HVAC system. Not only do they keep dirt and other harmful contaminants away from HVAC components where they can cause damage, but they also remove those contaminants from the air you breathe.

But what kind of air filter should you use in your home? Which one will most effectively raise your indoor air quality?

Types of Air Filters

  • Fiberglass – Thin and flimsy, these filters are cheap but not particularly effective. They remove less than 10 percent of contaminants from the air.
  • Pleated – These have a similar construction to fiberglass filters, but they’re markedly better at their job, removing up to 45 percent of contaminants.
  • Electrostatic – Rather than simply creating a barrier to keep contaminants out, these actually have an electrostatic charge that attracts dust particles to it.
  • High efficiency – High efficiency air filters can remove around 85 percent of contaminants. However, they’re also very thick, restricting airflow. For this reason, they can’t be used in a regular HVAC system without damaging it. If your home needs a higher level of filtration, talk to your trusted technician to determine the best option for your HVAC system.

When looking for an air filter, check the minimum efficiency reporting value, or MERV rating. This reflects the percentage of contaminants the filter can remove and the size of the particles it can stop. Most HVAC systems should have a filter rated between 9 and 12.

Air Filter Maintenance

No matter what air filter you choose, it’s important to check it regularly. A dirty air filter restricts airflow, overworking the HVAC system as it struggles to heat or cool your home. This not only wastes energy, but it also shortens the system’s life span. A clogged filter will also fail to keep contaminants from circulating through your home’s air, lowering IAQ and exacerbating allergies and asthma. Air filters should be checked monthly and replaced at least every three months to maintain efficiency.

"Ernie & Mike did a superb job on my new furnace and A/C installation. Despite having more than a day’s work to do, they came in and stayed until the job was done. They were organized, efficient, and protected the rest of the house well. Got both furnace and A/C installed the same day. Ernie was courteous, informative, and clearly knew his job better than anyone I’ve encountered before. The units look so good guests now get The Tour of our new system. Apollo is clearly not a fly-by-night company. I would recommend them to anyone in need of a new furnace and/or A/C."

"I called Apollo because of a water leak I thought I had in our upstairs shower going into the kitchen. Robbie came and assured me everything was fine & looked at all the other plumbing. He ended up changing a few pipes for our washer & clearing a drain. He was very nice & knowledgeable with all my questions. I ended up signing up for the care plan & was very happy with my service."
- Cassandra B.
"The team at Apollo exceeded my expectations. As a business owner, my attention to the details and commitment to providing excellent service is high. From the sales rep. to the installation team, everyone’s performance was outstanding. For example, the installation team went to great lengths to protect our floors, placing floor runners and across the wood floors and up the stairs. They even were spot washing walls upon their departure. I highly recommend this company."

"We scheduled an estimate AND a tune-up. We knew something was wrong with our furnace, but hoped we could make it through the rest of the season. Upon telling Bill what our furnace was doing, he warned us immediately what the possible outcome was going to be; a cracked heat exchanger. He watched the flames roll backward, tested carbon monoxide levels, which were so high they meter’s last reading was 5,600 before saying “high”. He immediately shut it down, tagged it, and explained that with levels that high and children in our home he wanted off right away. He continued his inspection and showed us via a camera that not only was it cracked in multiple places, but had holes all over it. He gave us a few options for repairing it; his knowledge as well as genuine concern was beneficial and refreshing. Luckily we also scheduled an estimator, Micah, to come too and we were able to get costs between repairing and replacing (with several options). We decided to replace with a much higher efficiency furnace and one sized properly to our home. Hands down, not only did they both provide us great service and knowledge, but without sounding dramatic, they may have saved our lives. This was our first time calling Apollo, but it won’t be our last."

"Apollo is an excellent company. I always receive great service. Alex A. was professional and friendly. He kept me informed during the process of checking my furnace and heat pump to make sure they were working properly. The company makes sure you are notified who is coming and when they are on the way. All my interactions with the company have been wonderful."
