    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.
