  • What is MERV
    High quality pleated furnace filters and pleated AC filters, made from a synthetic media can help keep your home's air clean for up to 90 days. Use pleated HVAC filters to remove small particles such as mold, dust and more that pass through cheap spun fiberglass filters. Pet dander, mold, secondhand smoke, household cleaning products and more all contribute to dirty air inside your home. The fact that people spend 90% of their time indoors, and that the air inside is often more dirty than the air outside, led the EPA to name Indoor Air Quality (IAQ) as a top five environmental health risk. Change your home air filters regularly to prevent temporary and long-term negative health effects from breathing in dirty air.
