Why MERV rating and filter thickness is important?
MERV stands for Minimum Efficiency Reporting Value and is an industry standard to rate a filters efficacy. We recognize this is not very easy to understand for consumers, so we developed our simple to use application naming system. Simply pick the filter that suits your needs.
Allergies, pets, odors and smoking all can greatly affect the quality of your indoor air. Discount Filters offers many different types of air filters to help you breathe easier and choose the correct filter based on your specific needs.
Ensuring that your filter fits properly in your HVAC system means making sure that you have not only the right length and width, but also the thickness of your filter.
Most standard air filters are 1 - 2 inches in thickness. Whereas media filters are typically 3 to 5 inches in thickness. The best way to measure your air filter size is to get out the measuring tape and measure it directly. Also your current filter probably has the dimensions printed on the frame.
