Features

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.

Removes up to 95% of small airborne particles.

Removes up to 95% of germs, viruses, and infectious bacteria like MRSA and other living microorganisms.

Removes up to 99% of medium airborne particles.

Removes up to 99% of allergy-aggravating particles like mold, mildew, pet dander, or smog.

Removes 100% of large airborne particles

Removes up to 100% of dust, pollen, lint and other large particles to make your home's air healthier. It does all this without adding to the cost of running your heating and cooling system.

Resources

Products that add to the performance of PureAir S Purification System

  • * 1 Removal efficiency based on third party testing results using MS-2 bacteriophage (ATCC 15597-B1). Bacteria representative of virus-sized particles like SARS-CoV-2, the virus that causes COVID-19. November 2020.
  • ** 2 When used properly with other best practices recommended by CDC and others, filtration can be part of a plan to reduce the potential for airborne transmission of COVID-19 indoors.
  • *** 3 Not intended for actual hospital use. Based on Application Guidelines, Table 1, ASHRAE Application Handbook, 2011.
  • † 4 Based on ozone removal testing conducted by third party testing results. May 2018.
  • ‡ 5 Based on competitive benchmarking of MERV 16 filters, Healthy Climate® filters have the lowest air flow restriction. Greater restriction of air flow creates a greater load on an HVAC unit’s fan motor, increasing energy consumption.
