Two filters have been added to the portfolio of Filtrete™ Commercial HVAC filters. The MERV A13 and MERV A11 are designed with an innovative open filtration media structure, precision pleat structure, and high-surface area mini-pleat design, resulting in low pressure drop, thereby helping decrease energy use. The MERV A13 rated filter meets the minimum requirement for an Indoor Environmental Quality point toward LEED certification for new and existing buildings. The filter offers a unique combination of high in-use efficiency, low pressure drop, and a long filter life, all in a compact filter package, says the company. The MERV A11 features a robust design for a wide range of building HVAC environments due to its durable, moisture- and humidity-resistant, 100 percent synthetic filtration media, 100 percent metal-free filter design, and engineered frame construction.
