3 Best Air Purifiers for Boosting Your Homes Indoor Air Quality

February 04, 2021

If you own a newer home in Lafayette, it was probably made 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 economical, they’re not so great for your indoor air quality.

Your heating and cooling system needs to run with a filter. But if you have a flat filter, you won’t be experiencing adequate filtration. This model only delivers the bare minimum 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 adequate filtration, even more so if someone in your residence has allergies or other respiratory problems.

That’s where a whole-house air purifier can be a great solution. These systems are placed within ductwork to deliver strong filtration around your home. 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 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 the best filtration. These filters were first created to defend scientists as they made 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 larger irritants before the HEPA filter captures the remainder of miniscule irritants. Then, a charcoal filter takes care of odors and chemical vapors.

It’s also potent at decreasing or eliminating 90%1 of flu and cold viruses under certain airflow conditions. And, based on laboratory and field studies, it removes and eradicates approximately 50% of residential odors and chemical vapors within 24 hours.

The PureAir S comes with sensing features that make it easy to keep up. When linked with an iComfort® S30 smart thermostat, you’ll get a notification to change 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 measures how effective filters are at trapping contaminants. The higher the number, the finer the filtration.

The Healthy Climate Carbon Clean 16® Media Air Cleaner is great for families with allergy suffers and pets. This is a HEPA filter air purifier, since it has a MERV 16 rating for hospital-level filtration. And it gets rid of more than 95%3 of aggravating particles from your house’s air.

The Healthy Climate 13 Media Air Cleaner is great for homes who are looking for stronger protection from viruses and bacteria. This filter captures 99% of larger particles such as dust, pollen and lint. And up to 54% of finer particles down to 0.3 microns.4

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 provide this powerful filtration without driving up the bill for operating your home comfort system.

These three media air cleaners are compatible 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 limit your system’s airflow. This can increase your utility expenses.
