If you own a newly constructed house in Covington, it was likely built with energy efficiency at the top of the list. This means more insulation and windows and doors with enhanced seals. While these improvements are excellent for keeping your heating and cooling expenses economical, they’re not so fantastic for your indoor air quality.

Your HVAC system needs to run with a filter. But if you have a flat filter, you won’t be getting enough filtration. This kind only gives the bare minimum of protection by stopping dust from getting into your home comfort system.

While you can get a pleated filter or one with a increased MERV rating, it still might not be enough filtration, even more so if someone in your residence has allergies or other respiratory issues.

That’s where a whole-house air purifier comes in. These systems are placed within ductwork to provide strong filtration around your residence. Depending on the model you choose, you’ll be able to filter allergens, odors and even some viruses under certain airflow conditions.

Here are our best solutions from Lennox, an industry leader in air purification.

Best Air Purifiers from Lennox

1. HEPA Air Purifiers

A HEPA air purifier, like the Healthy Climate® High-Efficiency Particulate Air Filtration System, delivers the best filtration. These filters were first made to guard scientists as they worked on the atomic bomb. Today, they’re a staple in hospitals and other medical buildings.

The Healthy Climate HEPA Filtration System features a three-step filtration procedure. A prefilter catches larger pollutants before the HEPA filter traps the rest of smaller particles. Then, a charcoal filter wipes out odors and chemical vapors.

The PureAir™ S Air Purification System works with all HVAC brands and seamlessly works with your smart home. It combats the three key varieties of indoor air contaminants:

  • Airborne particles
  • Chemical odors and vapors
  • Germs and bacteria, under certain airflow conditions

This air purifier can get rid of 99.9%* of pollutants, including mold spores, pollen, dust and pet dander. It’s also effective at reducing or eliminating 90%1 of flu and cold viruses under certain airflow conditions. And, based on laboratory and field studies, it decreases and destroys approximately 50% of household odors and chemical vapors within 24 hours.

The PureAir S is equipped with sensing features that make it simple to keep up. When used with an iComfort® S30 smart thermostat, you’ll be notified when to change the filter and UVA light.2 This home air purifier must be linked with communicating Lennox systems and the iComfort S30.

2. Media Air Cleaners

Lennox Healthy Climate® Media Air Cleaners are available in a variety of MERV ratings to work with your needs. This rating determines how good filters are at removing contaminants. The higher the number, the better the filtration.

The Healthy Climate Carbon Clean 16® Media Air Cleaner is recommended for households with allergy suffers and pets. This is a HEPA filter air purifier, since it has a MERV 16 rating for hospital-grade filtration. And it eliminates more than 95%3 of irritating particles from your house’s air.

The Healthy Climate 13 Media Air Cleaner is recommended for families who desire improved protection from viruses and bacteria. This filter removes 99% of larger particles like dust, pollen and lint. And up to 54% of smaller particles down to 0.3 microns.4

The Healthy Climate 11 Media Air Cleaner is a a great air purifier for allergies and in homes with pets. It removes more than 87% of bigger particles down to 3 microns and more than 28% of smaller ones down to 0.3 microns.4 It’s able to deliver this effective filtration without increasing the bill for turning on your home comfort system.

These three media air cleaners work with any brand of HVAC system. However, it’s critical to know that some of the more substantial ones, like MERV 16 and 13, may limit your system’s airflow. This can increase your energy expenses.

3. UV Air Purifiers

The sun’s UV rays are the fault of why you get a painful sunburn. But this wavelength of light has a helpful application when placed in your ductwork. It’s also powerful enough to decrease germs, mold and fungi under certain airflow conditions.

In fact, the Healthy Climate UV Germicidal Light can decrease the number of airborne microorganisms by 50% in as quickly as 45 minutes.5 This light wrecks cell structure, which stops these microorganisms from growing and infiltrating around your home.

And this UV air purifier can also help keep your heating and cooling system clean and running properly. It takes care of germs, mold and fungi that are hidden within ductwork and your system itself. This UV light air purifier does all these things without developing lung-aggravating ozone.6
