Plan ahead for 2018 - get a great deal on furnace filters from Global Filters. If you follow my advice of changing your furnace filters every three months, January is a great time to start. I really like the quality of the filters from Global Filter Source and the prices on their site are much cheaper than buying filters from Home Depot or Lowes.
Take a look at the website - the best deal is on the MERV 11 filters. All you need is your filter size and you can get enough filters to cover all your needs for the year. You can use the coupon below for an additional 10% off your order.
