How good are the standard blue throwaway filters?
In short, better than nothing, these throwaway filters that can be purchased for less than a dollar filter out about 15% of particulates (leaving 85% to go right on through to your coil and ductwork. However, if your unit is over 12 years old you may need to use these standard blue filters to ensure that there isn’t too much reduction in air flow. The health of your system as well as your family are important to us. Give Merritt Air a call or email us, we would be happy to review your filtration options with you.
