What is MERV
    Today, people spend up to 90% of their time indoors. This makes the air we breathe inside important to our short and long-term health. Indoor air pollutants such as household cleaning products, mold and pet dander can be effectively cleaned from the air when a home's air filter is changed every 90 days or sooner. Don't risk you or your families health. Be sure to follow the manufacturer recommendations and even change your HVAC filter sooner if it is dirty when checked.
