3 Best Air Purifiers for Boosting Your Houses Indoor Air Quality

February 04, 2021

If you live in a newer home in Tuscaloosa, it was probably built with energy efficiency in mind. This means greater amounts of insulation and windows and doors with better seals. While these advances are great for keeping your energy expenses affordable, they’re not so excellent for your indoor air quality.

Your home comfort system needs to work with a filter. But if you have a flat filter, you won’t be receiving enough filtration. This model only delivers the smallest amount of protection by blocking dust from infiltrating your HVAC system.

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

That’s where a whole-house air purifier comes in. These systems are placed within ductwork to give effective filtration around your house. Depending on the type you choose, you’ll be able to get rid of allergens, odors and even some viruses under certain airflow conditions.

Here are our top systems 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, gives the best filtration. These filters were first developed to shield scientists as they created the atomic bomb. Today, they’re necessary in hospitals and other medical buildings.

The Healthy Climate HEPA Filtration System features a three-step filtration procedure. A prefilter draws larger irritants before the HEPA filter catches the rest of tiny irritants. Then, a charcoal filter eradicates odors and chemical vapors.

The PureAir™ S Air Purification System works with all HVAC brands and seamlessly works with with your smart home. It reduces the three leading kinds of indoor air pollutants:

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

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

The PureAir S comes with sensing features that make it easy to serviced. When linked with an iComfort® S30 smart thermostat, you’ll receive an alert to replace 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 are made in a variety of MERV ratings to fit your needs. This rating calculates how good filters are at removing contaminants. The higher the number, the greater the filtration.

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

The Healthy Climate 13 Media Air Cleaner is recommended for households who desire stronger 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 fantastic air purifier for allergies and in houses with pets. It catches 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 effective filtration without increasing the cost of operating your HVAC system.

These three media air cleaners are compatible with any brand of HVAC system. However, it’s critical to be aware that some of the denser ones, including MERV 16 and 13, may decrease your system’s airflow. This can inflate your energy costs.

3. UV Air Purifiers

The sun’s UV rays are to blame when you get a painful sunburn. But this wavelength of light has a useful application when concealed inside your ductwork. It’s also powerful enough to reduce germs, mold and fungi under certain airflow conditions.

In reality, the Healthy Climate UV Germicidal Light can lower the amount of airborne microorganisms by 50% in as fast as 45 minutes.5 This light damages cell structure, which stops these microorganisms from multiplying and infiltrating across your home.

And this UV air purifier can also help keep your heating and cooling system clean and working properly. It takes care of germs, mold and fungi lurking inside ductwork and your system itself. This UV light air purifier does all these things without producing lung-irritating ozone.6
