Lennox International, a global company in the heating, air conditioning, and refrigeration markets, is revolutionizing the commercial HVAC industry by introducing the rooftop unit Ultimate Indoor Air Quality system as part of its Building Better Air initiative.

The Ultimate IAQ system

With the ability to remove 99% of the virus that causes COVID-19 from the air, Lennox has developed a rooftop unit that can help commercial businesses improve the health of their building.

Using a factory-installed combination of MERV 16 filters and UVC Germicidal lamp, the Ultimate IAQ system has been third-party tested to show a 95% single-pass efficiency rate with a 70% virus reduction rate after five minutes and 99% reduction after 30 minutes.

Lab-test healthy building solution

"We are excited to bring to market a game-changing, healthy building solution with the Ultimate IAQ system," said Elliot Zimmer, EVP, president & COO of Lennox Commercial.

The Ultimate IAQ system has been lab-tested by a third party so the customers can feel confident 

"When we kicked off the Building Better Air initiative last year, we promised to continue to develop innovative solutions to help our customers improve the indoor air quality of their buildings. The Ultimate IAQ system has been lab-tested by a third party so that our customers can feel confident they are making a positive impact on the health of their buildings."

Promotes better air

The Ultimate IAQ system uses a variety of technologies to promote better air in commercial spaces. The MERV 16 Filter eliminates 95% of particles down to 0.3 microns, an industry first for light commercial rooftop units.

The factory-installed UVC lights target various viruses, bacteria, and mold spores by treating the interior surfaces of the unit. In addition to these purification technologies, the Ultimate IAQ system also uses Humiditrol™+ to efficiently remove excessive humidity from interior spaces and maintain year-round comfort for employees and customers.

A safe, comfortable building environment

"Our goal with the Ultimate IAQ system is to help businesses provide a safe, comfortable building environment for their customers and employees," said Bobby DiFulgentiz, vice president of commercial product management and marketing.

"Our development focus was to effectively integrate air purification and humidity control features into our Model L rooftop line to deliver the best indoor air quality solution in the light commercial market.”

“We are extremely proud to not only offer this to our customers but back it up with impactful testing data that confirms what the Ultimate IAQ system can do to improve a building's environment."
