Make Your Houses Air Healthier with These 3 Best Air Purifiers

February 04, 2021

If you live in a newer house in Newton, it was in all likelihood built with energy efficiency in mind. This means greater amounts of insulation and windows and doors with enhanced seals. While these enhancements are excellent for keeping your energy costs in check, they’re not so fantastic for your indoor air quality.

Your HVAC system needs to work with a filter. But if you rely on a flat filter, you won’t be experiencing ample filtration. This kind only gives the lowest level of protection by keeping dust out of your HVAC system.

While you can get a pleated filter or one with a better MERV rating, it still might not be enough filtration, particularly 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 deliver strong filtration throughout your home. Depending on the model you select, you’ll be able to get rid of allergens, odors and even some viruses under certain airflow conditions.

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

The Healthy Climate HEPA Filtration System includes a three-step filtration process. A prefilter catches larger pollutants before the HEPA filter catches the remainder of smaller irritants. Then, a charcoal filter wipes out odors and chemical vapors.

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

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

This air purifier can remove 99.9%* of pollutants, such as mold spores, pollen, dust and pet dander. It’s also capable of removing or eliminating 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 residential odors and chemical vapors within 24 hours.

The PureAir S is equipped with sensing features that make it easy to keep up. When used with an iComfort® S30 smart thermostat, you’ll be notified when to replace 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 are available 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 better the filtration.

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

The Healthy Climate 13 Media Air Cleaner is recommended for families who are looking for enhanced protection from viruses and bacteria. This filter traps 99% of larger particles such as 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 fantastic air purifier for allergies and in residences with pets. It eliminates 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 offer this powerful filtration without driving up the bill for turning on your HVAC system.

These three media air cleaners work with any brand of HVAC system. Regardless, it’s essential to be aware that some of the denser ones, including MERV 16 and 13, may restrict your system’s airflow. This can increase your heating and cooling bills.

3. UV Air Purifiers

The sun’s UV rays are to the reason why you get a stinging sunburn. But this kind of light has a beneficial application when placed inside your ductwork. It’s also strong enough to reduce germs, mold and fungi under certain airflow conditions.

In reality, the Healthy Climate UV Germicidal Light can decrease the number of airborne microorganisms by 50% in as little as 45 minutes.5 This light damages cell structure, which prohibits these microorganisms from multiplying and spreading throughout your home.

And this UV air purifier can also help keep your home comfort system clean and working properly. It wipes out of germs, mold and fungi lurking in ductwork and your system itself. This UV light air purifier achieves all these things without creating lung-irritating ozone.6
