3 Best Air Purifiers for Improving Your Homes Indoor Air Quality

February 04, 2021

If you have a newly built house in Laurel, it was in all likelihood made with energy efficiency in mind. This means greater amounts of insulation and windows and doors with better seals. While these enhancements are good for keeping your energy costs affordable, they’re not so great for your indoor air quality.

Your home comfort system needs to run with a filter. But if you install a flat filter, you won’t be getting ample filtration. This model only delivers the bare minimum of protection by keeping dust out of your HVAC system.

While you can upgrade to a pleated filter or one with a better MERV rating, it still might not be ample filtration, especially if someone in your residence has allergies or other respiratory issues.

That’s where a whole-house air purifier can be a great solution. These systems are attached within ductwork to deliver mighty filtration across your house. Depending on the kind you choose, you’ll be able to remove allergens, odors and even some viruses under certain airflow conditions.

Here are our best styles 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 created to shield 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 significant particles before the HEPA filter captures the remainder of miniscule particles. Then, a charcoal filter wipes out odors and chemical vapors.

The PureAir™ S Air Purification System connects to all HVAC brands and smoothly connects with with your smart home. It combats the three major types of indoor air contaminants:

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

This air purifier can remove 99.9%* of pollutants, including mold spores, pollen, dust and pet dander. It’s also effective at decreasing or eradicating 90%1 of flu and cold viruses under certain airflow conditions. And, as the result of laboratory and field studies, it decreases and eliminates approximately 50% of residential odors and chemical vapors within 24 hours.

The PureAir S includes sensing features that make it simple to keep up. When linked with an iComfort® S30 smart thermostat, you’ll receive an alert to change the filter and UVA light.2 This home air purifier must be used 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 measures how good filters are at capturing contaminants. The better the number, the finer the filtration.

The Healthy Climate Carbon Clean 16® Media Air Cleaner is great for households 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 eliminates more than 95%3 of unhealthy particles from your house’s air.

The Healthy Climate 13 Media Air Cleaner is great for homes who are looking for improved protection from viruses and bacteria. This filter removes 99% of larger particles including dust, pollen and lint. And up to 54% of finer particles down to 0.3 microns.4

The Healthy Climate 11 Media Air Cleaner is a a great 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 finer ones down to 0.3 microns.4 It’s able to deliver this powerful filtration without running up the price of using your home comfort system.

These three media air cleaners can be used with any brand of HVAC system. Regardless, it’s critical to realize that some of the more substantial ones, like MERV 16 and 13, may limit your system’s airflow. This can hike up your utility costs.

3. UV Air Purifiers

The sun’s UV rays are to the reason why you get a stinging sunburn. But this type of light has a useful application when installed inside your ductwork. It’s also powerful enough to decrease germs, mold and fungi under certain airflow conditions.

In reality, the Healthy Climate UV Germicidal Light can decrease the concentration of airborne microorganisms by 50% in as little as 45 minutes.5 This light damages cell structure, which prohibits these microorganisms from growing and infiltrating around your residence.

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 hiding inside ductwork and your system itself. This UV light air purifier accomplishes all these things without developing lung-aggravating ozone.6
