  • What is MERV
    Pleated furnace filters and pleated AC filters will clean your home's air more effectively than low cost fiberglass air filters. Pleated home air filters are made from a synthetic media which can filter out much smaller particles from the air such as dust mites, mold, pet dander and even viruses in the case of high Merv rated filters. The EPA has named Indoor Air Quality (IAQ) as one of the top 5 environmental health risks. Today, people spend almost 90% of their time indoors exposed to air contaminants such as household cleaning products, pet dander, secondhand smoke, mold and more. Change your home air filters regularly to avoid temporary discomfort and the long-term health effects of breathing dirty air.
