HOUSTON — RectorSeal, a manufacturer of HVACR and plumbing accessories, has announced the addition of the Flow Right filter box to its extensive line of IAQ products for HVAC systems.

Flow Right air filter boxes complement RectorSeal's dust-free IAQ products by providing a unique knock-down design, a press release from RectorSeal said. Patented in 2015, Flow Right filter boxes are ready-to-assemble filter cabinets that are compatible with 1- and 2-inch air filters. They are packaged flat in easy-to-store cartons and take minutes to assemble, the press release said.

The filter boxes are adjustable from 4 inches to 18 inches in height and are available in galvanized or powder-coated options. When properly installed, Flow Right box filters can help to improve HVAC airflow by up to 20% in a ducted HVAC system, the press release said.

“The addition of Flow Right box filters ensures RectorSeal’s ability to deliver innovative, practical, and effective HVAC solutions to our customers,” said Gregg Burnett, vice president and general manager of dust-free IAQ products at RectorSeal.
