Houston, TX, September 17, 2024—RectorSeal, a leading manufacturer of HVAC/R and plumbing accessories, has announced the launch of Dust Free Sixteen, a high-efficiency, low-resistance MERV 16 media air cleaner designed to provide superior whole-home air filtration with minimal maintenance and energy consumption. The Sixteen boasts a remarkable filter life of up to three years, making it a long-lasting indoor air quality solution.

Dust Free Sixteen integrates seamlessly into upflow, horizontal, attic, and basement HVAC systems. Its design features multiple pleated media filters, offering up to 280 square feet of long-lasting media surface area with a pressure drop that rivals less-efficient MERV 8 filters. The Sixteen captures allergens, smoke particles, and bacteria as small as 0.3 microns.

The Sixteen will provide years of reliable operation. It is solidly built with corrosion-resistant materials, including a 3003 aluminum cabinet, ABS plastic frame corners, and aluminum filter rails. It ships partially assembled for easy transport and quick field assembly. Available in 3-ton and 5-ton sizes, the Sixteen meets SEER 2 requirements for energy efficiency.

“Dust Free Sixteen sets a new standard for MERV 16 filtration,” said Gregg Burnett, VP and GM of Dust Free. “It offers cleaner and healthier air without compromising efficiency or convenience for our customers.”
