<p>The Accumulair Platinum is a superior choice for residential filtration and is a better solution for commercial use. This filter uses electrostatic filtration to remove 65-79% of air pollutants ranging in size from 1.0 microns to 3.0 microns. This means that it removes a large bulk of particles like dust mites, bacteria, pet dander, pollen, smoke, and mold spores. Though rated as a medium-efficiency filter, the Accumulair Platinum filter has special electrostatic filtration that is almost equal to that of a true HEPA filter, and it achieves a 60-65% dust spot efficiency. This feature makes the Accumulair Platinum filters 30 times more efficient than regular fiberglass filters. These filters made to fit any filter system.</p><strong>Features</strong><ul><li>MERV 11 Rating</li><li>Supercharged pleated panel filtering media ideally suited for capturing fine airborne allergens such as dust, smoke, dander, mold, pet dander, and dust mites attracts particulates like dust to a TV screen.</li><li>Uniform pleat shape enhances dust holding capacity and maximizes air flow.</li><li>Heavy duty construction frame prevents airflow bypass</li><li>Electrostatic filtration</li><li>Listed and rated by Underwriters Laboratories as U.L.

These filters are constructed of a special Tribo-Electric synthetic media, which ultimately leads to higher efficiency and low resistance to air flow. Not only do the co-polymer micro-fibers help produce higher efficiency, but they are also hydrophobic, which means the filter does not absorb moisture and will not support the growth and spread of microbes like mold, mildew, bacteria, and fungi. For more dependable structure, the pleated filter media is laminated to a recyclable, galvanized, and corrosion resistant metal backing, which also contributes to low resistance to air flow. This media pack is then bonded to the inside of a two-piece, die cut frame that is constructed of a heavy duty, moisture resistant, clay coated board; designed with diagonal and horizontal grid supports, this final product produces longer, stronger durability for the filter.</p>
