Boost Your Residences Air Quality with These 3 Best Air Purifiers

February 04, 2021

If you live in a newer house in Racine, it was likely constructed with energy efficiency as a priority. This means more insulation and windows and doors with better seals. While these advances are good for keeping your heating and cooling expenses economical, they’re not so fantastic for your indoor air quality.

Your HVAC system needs to operate with a filter. But if you’re using a flat filter, you won’t be receiving ample filtration. This model only gives the lowest level of protection by blocking dust from infiltrating your home comfort system.

While you can upgrade to a pleated filter or one with a higher MERV rating, it still might not be ample filtration, especially 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 installed within ductwork to provide effective filtration around your house. Depending on the type you select, you’ll be able to remove allergens, odors and even some viruses under certain airflow conditions.

Here are our favorite 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 guard scientists as they worked on the atomic bomb. Today, they’re must-have in hospitals and other medical applications.

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

The PureAir™ S Air Purification System works with all HVAC brands and easily connects with with your smart home. It combats the three major types 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, 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 eliminates approximately 50% of household odors and chemical vapors within 24 hours.

The PureAir S is equipped with sensing features that make it easy to maintain. When linked with an iComfort® S30 smart thermostat, you’ll get a notification to install a new 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 available in a variety of MERV ratings to match your needs. This rating determines how capable filters are at trapping contaminants. The greater the number, the better the filtration.

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

The Healthy Climate 13 Media Air Cleaner is recommended for families who are looking for improved protection from viruses and bacteria. This filter catches 99% of larger particles including 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 an excellent air purifier for allergies and in residences with pets. It removes 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 effective filtration without driving up the bill for using your HVAC system.

These three media air cleaners work with any brand of HVAC system. However, it’s critical to be aware that some of the denser ones, such as MERV 16 and 13, may restrict your system’s airflow. This can inflate your heating and cooling costs.

3. UV Air Purifiers

The sun’s UV rays are to blame when you get a blistering sunburn. But this kind of light has a beneficial application when installed 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 reduce the concentration of airborne microorganisms by 50% in as fast as 45 minutes.5 This light destroys cell structure, which halts these microorganisms from growing and infiltrating throughout your residence.

And this UV air purifier can also help keep your HVAC system clean and running properly. It takes care of germs, mold and fungi lurking inside ductwork and your system itself. This UV light air purifier achieves all this work without making lung-irritating ozone.6
