A Filter is Just a Filter, Right?

filters mervUnfortunately, all filters are not created equally.  Improper sized filters or even dirty filters are the number one reason for furnace or air conditioner failure.  We are here to take the mystery out of filter shopping and make sure your furnace runs as long and efficiently as possible.

  1. Does Size Matter?
    • Size difference is pretty obvious, as some are rectangle, square, thick, thin, etc.  The most important thing to remember is the thinner filters actually need to be changed or at least checked monthly.  The 1″ filter panels usually don’t seal as well, resulting in air bypassing it, causing a shorter life span of your furnace. The thicker pleated filters (4″-5″ thick) only need to be changed twice a year. Also, the filter will do its job best when it is properly sized for your unit.
  2. img_0613What is MERV Rating?
    • MERV stands for Minimum Efficiency Reporting Value and so you would think the higher the MERV rating the better, right? Not according to Mike, Mike’s Heating and Cooling generally recommends the highest rating of MERV 8.  If you get much higher, the furnace has to work harder to draw air through the filter, which will hinder its efficiency and shorten the life of your furnace.
  3. Pleated vs Panel
    • Economy panel filters are sold 4-5 in a pack and are inexpensive. These filters simply do not filter much and you will be replacing them about once a month.
    • Pleated filters, can last six months to a year, and are 10% to 60% more efficient.
  4. Can I Upgrade My Filter?
    • Yes.  Mike’s Heating & Cooling would love to come to your location and if you have enough space around your furnace, we can add a cabinet so you can use a more efficient filter, enjoy cleaner indoor air, and save on your energy bill.
