3 Best Air Purifiers for Improving Your Houses Indoor Air Quality

February 04, 2021

If you own a newly constructed home in New Castle, it was in all likelihood constructed with energy efficiency in mind. This means greater amounts of insulation and windows and doors with improved seals. While these enhancements are good for keeping your energy costs under control, they’re not so good for your indoor air quality.

Your HVAC system needs to run with a filter. But if you’re using a flat filter, you won’t be receiving enough filtration. This model only gives the smallest amount of protection by keeping dust out of your home comfort system.

While you can get a pleated filter or one with a better MERV rating, it still might not be ample filtration, even more so if someone in your house has allergies or other respiratory problems.

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

Here are our top options 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, provides premium filtration. These filters were first developed to guard scientists as they developed the atomic bomb. Today, they’re necessary in hospitals and other medical facilities.

The Healthy Climate HEPA Filtration System includes a three-step filtration method. A prefilter attracts significant pollutants before the HEPA filter captures remaining smaller particles. Then, a charcoal filter wipes out odors and chemical vapors.

The PureAir™ S Air Purification System connects to all HVAC brands and seamlessly links to with your smart home. It fights the three leading kinds of indoor air irritants:

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

This air purifier can eliminate 99.9%* of pollutants, including 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, based on laboratory and field studies, it removes and destroys approximately 50% of your home’s odors and chemical vapors within 24 hours.

The PureAir S includes sensing features that make it simple to keep up. When paired 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 made in a variety of MERV ratings to work with your needs. This rating measures how capable filters are at removing contaminants. The better the number, the finer the filtration.

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

The Healthy Climate 13 Media Air Cleaner is great for households who are looking for enhanced protection from viruses and bacteria. This filter captures 99% of larger particles including 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 houses 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 strong filtration without increasing 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 be aware that some of the denser ones, including MERV 16 and 13, may restrict your system’s airflow. This can increase your utility expenses.

3. UV Air Purifiers

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

In actuality, the Healthy Climate UV Germicidal Light can reduce the amount of airborne microorganisms by 50% in as little as 45 minutes.5 This light damages cell structure, which stops these microorganisms from multiplying and spreading throughout your residence.

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