3 Best Air Purifiers for Improving Your Homes Indoor Air Quality

February 04, 2021

If you have a newly constructed house in St. Louis, it was likely made with energy efficiency in mind. This means more insulation and windows and doors with better seals. While these improvements are good for keeping your energy bill under control, they’re not so great for your indoor air quality.

Your home comfort system needs to work with a filter. But if you install a flat filter, you won’t be receiving adequate filtration. This kind only gives the smallest amount 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 ample filtration, particularly if someone in your house has allergies or other respiratory troubles.

That’s where a whole-house air purifier can be a good option. These systems are installed within ductwork to deliver powerful filtration around your residence. Depending on the type you choose, you’ll be able to filter allergens, odors and even some viruses under certain airflow conditions.

Here are our favorite 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 top-of-the-line filtration. These filters were first developed to guard scientists as they created 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 process. A prefilter catches significant particles before the HEPA filter captures remaining tiny particles. Then, a charcoal filter takes care of odors and chemical vapors.

The PureAir™ S Air Purification System connects to all HVAC brands and easily integrates with your smart home. It reduces the three key kinds of indoor air pollutants:

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

This air purifier can get rid of 99.9%* of pollutants, like mold spores, pollen, dust and pet dander. It’s also potent at removing or eliminating 90%1 of flu and cold viruses under certain airflow conditions. And, according to laboratory and field studies, it reduces and eradicates approximately 50% of residential odors and chemical vapors within 24 hours.

The PureAir S comes with sensing features that make it uncomplicated to maintain. When linked with an iComfort® S30 smart thermostat, you’ll get a notification to change the filter and UVA light.2 This home air purifier must be installed with communicating Lennox systems and the iComfort S30.

2. Media Air Cleaners

Lennox Healthy Climate® Media Air Cleaners come in in a variety of MERV ratings to fit your needs. This rating determines how effective filters are at removing contaminants. The better the number, the greater the filtration.

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

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

The Healthy Climate 11 Media Air Cleaner is a a great air purifier for allergies and in residences 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 provide this powerful filtration without driving up the bill for turning on your heating and cooling system.

These three media air cleaners work with any brand of HVAC system. But despite that, it’s essential to know that some of the thicker ones, like MERV 16 and 13, may decrease your system’s airflow. This can increase your heating and cooling costs.

3. UV Air Purifiers

The sun’s UV rays are to blame when you get a painful sunburn. But this kind of light has a helpful application when installed in your ductwork. It’s also tough enough to decrease germs, mold and fungi under certain airflow conditions.

In fact, the Healthy Climate UV Germicidal Light can reduce the concentration of airborne microorganisms by 50% in as quickly as 45 minutes.5 This light destroys cell structure, which stops these microorganisms from growing and moving around your residence.

And this UV air purifier can also help keep your heating and cooling system clean and operating properly. It wipes out of germs, mold and fungi lurking inside ductwork and your system itself. This UV light air purifier achieves all these things without developing lung-irritating ozone.6
