Cheap Furnace Filters vs. Good Furnace FiltersPicture of Cheap Furnace filter

Are you currently using cheap furnace filters? Everyone loves to get stuff cheap but the old adage “you get what you pay for” certainly applies to the furnace filter products that are available today. Cheap furnace filters are available everywhere but are they a good choice for your family? Investing in a quality air filter for your HVAC furnace system will not only improve the performance of the furnace but also remove dust and allergens from your home.

Fiberglass Furnace Filters

If you are using cheap furnace filters that are made of fiberglass, you may want to reconsider. First of all, did you know that cheap furnace filters are made of FIBERGLASS? Do you think the fiberglass used to make these cheap air filters stays in place and never leaves the filter? Normally cheap filters for the furnace will come in white or blue and has a cardboard frame. Many times fiberglass furnace filters are see through. How well do you think a see through filter works? I have had people brag to me that their cheap furnace filters lasts six to nine months. How much indoor air pollution can pass through a filter in six months?

How Much Dust is in My Home?Picture AirSafe 2000 Air Filter before and after - Cheap furnace filters

“It is also estimated that an average home accumulates more than 40 pounds of dust a year according to the University of Missouri Health Care ENT and Allergy Center. -University of Missouri Health. The problem with all that dust is, millions of dust mites thrive in that environment. One of the most economical ways to capture dust is with a good furnace filter that is changed regularly.”

Steps to Choosing a Good Furnace Filter

When choosing a furnace filter for the air quality and extending the life of your furnace, here are some things to consider.

  1. Make sure the frame seals to the return air grille
  2. Make sure the frame does not allow air to bypass the furnace air filter
  3. Disposable filters are less likely to allow mold and other allergens to grow
  4. The furnace filter should allow air to move through it easily
  5. Furnace filters with high MERV ratings can damage furnaces.
  6. Furnace filters with the ability to capture and hold dust are less likely to pollute your home
  7. Furnace air filters that fit in the garbage can and do not contain cardboard are more environmentally friendly

The AirSafe 2000 Furnace Filter System is a great choice as a way to capture many of the particles that plague indoor air quality. They also allow air to move more freely through them than other high MERV rated filters on the market. When it comes to improving air quality by eliminating dust, dust mites, mold spores and more, you can’t go wrong with the AirSafe 2000 Furnace Filter System.

    I had to have my unit looked at because it was not cooling very well. The company that came out to check it told me the filters were too thick and were slowing the air flow therefore causing the cooling problems. They told me to get cheap filters!!!! So I have replaced the airsafe 2000 with a cheap filter and now have cool air!!!!! Go figure!!!!

      Hello Mary. Thank you so much for informing us about the problem with the AirSafe 2000 Furnace Filters working with your HVAC unit. I have done a bit of research and wanted to share what I have found. I hope this helps.I have studied some heat and air websites. Your return is approximately 10×24 or 240 square inches. Based on a 2 ton AC unit, the minimum return air grille size should be close to 600 square inches or a 20×30. You obviously made the right choice switching to a cheaper filter that allows air to flow more freely based on your HVAC tech recommendation. However, if it is in your ability to increase the size of the return air grille it would be a better choice for your HVAC unit as a whole. Even with a cheap furnace air filter the return may be undersized. Also, you may not have a 2-ton unit then the HVAC tech should calculate your return size based on your unit size. Again, thank you for the comment.
