If you own a newly constructed home in Huntsville, it was probably constructed with energy efficiency in mind. This means greater amounts of insulation and windows and doors with better seals. While these improvements are excellent for keeping your heating and cooling expenses in check, they’re not so great for your indoor air quality.

Your heating and cooling system needs to work with a filter. But if you have a flat filter, you won’t be getting adequate filtration. This type only delivers the bare minimum of protection by blocking dust from infiltrating your HVAC system.

While you can get a pleated filter or one with a higher 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 can be a good option. These systems are installed within ductwork to provide powerful filtration around your residence. Depending on the type you choose, you’ll be able to filter allergens, odors and even some viruses under certain airflow conditions.

Here are our favorite solutions 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 top-of-the-line filtration. These filters were first made to shield scientists as they developed the atomic bomb. Today, they’re a staple in hospitals and other medical applications.

The Healthy Climate HEPA Filtration System includes a three-step filtration method. A prefilter draws bigger particles before the HEPA filter captures the remainder of smaller pollutants. Then, a charcoal filter takes care of odors and chemical vapors.

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

  • 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 potent at 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 your home’s odors and chemical vapors within 24 hours.

The PureAir S includes sensing features that make it easy to service. When linked with an iComfort® S30 smart thermostat, you’ll receive an alert to replace 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 available in a variety of MERV ratings to work with your needs. This rating determines how effective 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 households with allergy suffers and pets. This is a HEPA filter air purifier, since it has a MERV 16 rating for hospital-strength filtration. And it removes more than 95%3 of unhealthy particles from your house’s air.

The Healthy Climate 13 Media Air Cleaner is suggested for households who are looking for stronger protection from viruses and bacteria. This filter catches 99% of larger particles like 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 homes with pets. It catches 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 powerful filtration without driving up the price of using your heating and cooling system.

These three media air cleaners work with any brand of HVAC system. However, it’s essential to know that some of the more substantial ones, such as MERV 16 and 13, may decrease your system’s airflow. This can hike up your energy expenses.

3. UV Air Purifiers

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

In actuality, the Healthy Climate UV Germicidal Light can lower the concentration of airborne microorganisms by 50% in as quickly as 45 minutes.5 This light damages cell structure, which halts these microorganisms from multiplying and infiltrating throughout your house.

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