3 Best Air Purifiers for Boosting Your Houses Indoor Air Quality

February 04, 2021

If you live in a newer residence in Hamilton, it was likely constructed with energy efficiency as a priority. This means greater amounts of insulation and windows and doors with improved seals. While these improvements are excellent for keeping your energy costs under control, they’re not so great for your indoor air quality.

Your HVAC system needs to work with a filter. But if you install a flat filter, you won’t be getting enough filtration. This model only gives the smallest amount of protection by blocking dust from infiltrating your HVAC system.

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

That’s where a whole-house air purifier can be a good option. These systems are attached within ductwork to provide strong filtration across your home. Depending on the kind you go with, you’ll be able to remove 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 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 buildings.

The Healthy Climate HEPA Filtration System has a three-step filtration method. A prefilter draws significant particles before the HEPA filter catches remaining miniscule pollutants. 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 combats the three key 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 effective at decreasing or eliminating 90%1 of flu and cold viruses under certain airflow conditions. And, according to 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 uncomplicated to serviced. When used with an iComfort® S30 smart thermostat, you’ll be notified when 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 fit your needs. This rating measures how good filters are at capturing contaminants. The higher 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, as it has a MERV 16 rating for hospital-grade filtration. And it gets rid of more than 95%3 of unhealthy particles from your house’s air.

The Healthy Climate 13 Media Air Cleaner is great for homes who are seeking enhanced protection from viruses and bacteria. This filter catches 99% of larger particles such as 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 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 smaller ones down to 0.3 microns.4 It’s able to deliver this powerful filtration without running up the price of turning on your home comfort system.

These three media air cleaners are compatible with any brand of HVAC system. But despite that, it’s important to realize that some of the more substantial ones, like MERV 16 and 13, may decrease your system’s airflow. This can hike up your utility bills.

3. UV Air Purifiers

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