Lennox Air Purification

The ultimate in whole-home air purification, offering hospital-grade filtration and smart sensing features.

This is the ultimate in safe, healthy, whole-home air purification. Offering hospital-grade3 filtration featuring the Lennox Healthy Climate® Carbon Clean 16® air filter that removes over 99% of the virus that causes COVID-191 from the air2, as well as even smaller viruses, bacteria, and fungal spores. Also, unlike other purification systems, the PureAir™ S produces zero lung-irritating ozone and actively removes existing ozone found in the home4. And its filter features a design that ensures the least airflow resistance5 for unmatched efficiency and consistently clean, perfect air.

A Signature of Excellence

The PureAir™ S Air Purification System is equipped with smart and sensing features that make maintaining your system a breeze. Built-in sensors monitor the life of both the filter and the Purifier UVA light so you don’t have to. When it’s time to change the filter or the Purifier, the PureAir™ S lets you know through your Lennox S40 Smart Thermostat.

Save energy, save money

Lennox proprietary filter design provides powerful, efficient filtration without restricting airflow, which can help lower utility bills and prolong the life of your heating and cooling system by helping to keep it free from dirt and dust buildup. Our deep pleat design absorbs more particles before having to replace the filter, potentially saving you money every year.

Reduces Ozone

Provides filtration throughout your home while reducing ozone, a known lung irritant. It helps remove harmful ozone from your home’s air and convert it into cleaner, healthier oxygen.

Chemical vapors and household odors are neutralized

As part of a natural and efficient purification process, carbon inside the filter that’s been treated with oxygen reacts with odors, neutralizing them before they can recirculate into your home. That means your air is free of household odors and volatile organic compounds (VOCs) from sources like cooking fumes, pets, cleaning supplies, paints and solvents, and carpeting and upholstery.
