3 Best Air Purifiers for Enhancing Your Residences Indoor Air Quality

February 04, 2021

If you live in a newly constructed house in Keokuk, it was in all likelihood made with energy efficiency at the top of the list. This means increased insulation and windows and doors with better seals. While these improvements are fantastic for keeping your utility expenses affordable, they’re not so fantastic for your indoor air quality.

Your home comfort system needs to operate with a filter. But if you rely on a flat filter, you won’t be getting adequate filtration. This model only provides the lowest level of protection by stopping dust from getting into your HVAC system.

While you can upgrade to a pleated filter or one with a increased MERV rating, it still might not be adequate filtration, especially if someone in your residence has allergies or other respiratory problems.

That’s where a whole-house air purifier comes in. These systems are attached within ductwork to deliver strong filtration across your residence. Depending on the kind you select, 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.
