Boost Your Homes Air Quality with These 3 Best Air Purifiers

February 04, 2021

If you own a newly built home in San Jose, it was probably made with energy efficiency at the top of the list. This means increased insulation and windows and doors with enhanced seals. While these improvements are fantastic for keeping your heating and cooling expenses under control, they’re not so fantastic for your indoor air quality.

Your home comfort system needs to work with a filter. But if you’re using a flat filter, you won’t be experiencing ample filtration. This model only provides the lowest level of protection by stopping dust from getting into your heating and cooling system.

While you can install a pleated filter or one with a higher MERV rating, it still might not be ample filtration, particularly if someone in your home has allergies or other respiratory problems.

That’s where a whole-house air purifier can be a good option. These systems are attached within ductwork to provide effective filtration throughout your house. Depending on the kind you go with, you’ll be able to get rid of 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, gives top-of-the-line filtration. These filters were first made to shield scientists as they developed the atomic bomb. Today, they’re must-have in hospitals and other medical applications.

The Healthy Climate HEPA Filtration System features a three-step filtration process. A prefilter draws bigger particles before the HEPA filter traps the rest of tiny particles. 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 types of indoor air contaminants:

  • 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 capable of decreasing or eradicating 90%1 of flu and cold viruses under certain airflow conditions. And, based on laboratory and field studies, it reduces and eradicates approximately 50% of your home’s odors and chemical vapors within 24 hours.

The PureAir S comes with sensing features that make it uncomplicated to maintain. When paired 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 linked 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 work with your needs. This rating measures how capable filters are at trapping contaminants. The greater the number, the finer the filtration.

The Healthy Climate Carbon Clean 16® Media Air Cleaner is great for homes 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 gets rid of more than 95%3 of irritating particles from your home’s air.

The Healthy Climate 13 Media Air Cleaner is suggested for homes who want stronger protection from viruses and bacteria. This filter captures 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 great air purifier for allergies and in residences with pets. It traps more than 87% of bigger particles down to 3 microns and more than 28% of miniscule ones down to 0.3 microns.4 It’s able to deliver this powerful filtration without increasing the bill for turning on your HVAC system.

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

3. UV Air Purifiers

The sun’s UV rays are to the reason why you get a painful sunburn. But this type of light has a helpful application when concealed in your ductwork. It’s also tough enough to eliminate germs, mold and fungi under certain airflow conditions.

In fact, the Healthy Climate UV Germicidal Light can lower the amount of airborne microorganisms by 50% in as quickly as 45 minutes.5 This light wrecks cell structure, which prohibits these microorganisms from flourishing and spreading throughout your house.

And this UV air purifier can also help keep your heating and cooling system clean and operating efficiently. It wipes out of germs, mold and fungi that are hidden in ductwork and your system itself. This UV light air purifier achieves all this work without developing lung-irritating ozone.6
