The Accumulair Diamond is one of the highest efficiency Accumulair filter on the market. Given a MERV 13 filter rating, this filter is a high efficiency filter that removes particulates measuring from 0.3 microns to 1.0 microns. This means that this filter removes a large variety of indoor air pollutants, including dust mites/particles, mold spores, pet dander, pollen, tobacco smoke, some viruses, and all bacteria. Accumulair Diamond filters use electrostatic filtration, which uses a special synthetic filter media to attract particles. With a dust spot efficiency of 89-90%, the Accumulair Diamond is more than 30 times more efficient than regular fiberglass filters and has a filter efficiency almost equivalent to a true HEPA filter.

The Accumulair Diamond is specifically designed to achieve points towards LEED certification. LEED, Leadership in Energy and Environmental Design, is an organization that rates projects delivering better environmental and health performance. Accumulair Diamond filters do this by providing higher efficiency, cleaner air, and longer-lasting filtration. When constructing the Accumulair Diamond, even the smallest details are important for designing the best that Accumulair has to offer. Made of 100% high performance Tribo-Electric synthetic media, the Accumulair Diamond takes electrostatic filtration to the next level. This special material, made of a co-polymer blend, creates higher efficiency with low resistance to air flow. These specially made fibers are also hydrophobic, meaning they will not absorb moisture, and they will not support the growth of harmful microbes like bacteria, mildew&
