How Often Should You Change Your Furnace Filter?

RE: How Often Should You Change Your Furnace Filter? Post By jeff house (Guest Post) (05/03/2008) I do heat & air for a living. I've always been told, change the filter every month.

I have a HVAC system and I use the Flanders PrecisionAire 14x30x1 filters. A case of 12 covers you for the year and it's $20.00 at Ace Hardware online. Delivered to your door!! That's a small price to pay for cleaner & healthier air in your home, especially if you have kids like me. Report Spam or Abuse RE: How Often Should You Change Your Furnace Filter?

In "their" ratings, they listed the cheapy filters, do next to nothing for filtering. The reusuable filters, (pricey) clean even less than the cheapies. In their tests, the best cleaning filter is made by 3M. It filters extremely well and doesn't restrict airflow (In their words) I loaned my Dad that magazine, so I'm sorry that I don't know the exact name of that 3M filter. I do remember it was around $12 dollars though and they recommend changing the filter once a month. So it could get quite expensive for that particular filter. I still use the Ace Hardware cheepies though and DO change them monthly! Hope this helps!! Steve, Blair, Nebr Report Spam or Abuse RE: How Often Should You Change Your Furnace Filter?

In the Spring they put filters on sale so I just buy a box or two of filters then. With no central AC we used seven or eight a year here in Northern Lower Michigan. Now I have just went back to full time wood heat and that furnace just sit there waiting. It doesn't know when it will ever get to run again. 8>)) Report Spam or Abuse RE: How Often Should You Change Your Furnace Filter?

I always write the date on the front of the filter when installing it so I know when it's due to be replaced. Report Spam or Abuse RE: How Often Should You Change Your Furnace Filter? Post By Holly (Guest Post) (08/29/2007) I work for a heating and air conditioning company and the honest answer is, it depends on what type of filter you have. If you are talking about 1" temporary filters, then yes those should be changed monthly. I have a high efficiency 4" filter and those don't need to be changed but once every 6 months. Hope this helps! Report Spam or Abuse RE: How Often Should You Change Your Furnace Filter? Post By Ann (Guest Post) (10/16/2005) We have always changed ours every month, all 12 months. I don't know if this has anything to do with it, but our system is fairly old and when we had a heating/cooling guy in this summer for a problem, he said our system was in great shape. I know some of our neighbors have replaced theirs several years ago. Report Spam or Abuse RE: How Often Should You Change Your Furnace Filter?

Reuse & recycle whenever possible. Report Spam or Abuse RE: How Often Should You Change Your Furnace Filter? Post By (Guest Post) (10/11/2005) Filters should be changed every 3 months at a minimum. More frequent filter changes are needed more for AC than heat. Report Spam or Abuse RE: How Often Should You Change Your Furnace Filter? Post by smcarney (103) | (10/11/2005) Profile | Contact I've been told that you should change your furnace filter every three months and possibly more if your area is extremely dusty. For us, I get the very cheap kind and change them every three months. Some of the better filters are reuseable, but have you seen how dirty they get? Good luck! Report Spam or Abuse RE: How Often Should You Change Your Furnace Filter? Post By Glenda (Guest Post) (10/11/2005) You are correct. The cleaner your air filter is kept the more efficient you furnace will run. Thus you save money on heating and repair bills. If you have natural gas you will want to save every penny you can this coming winter with prices expected to be 70% more than last year. Report Spam or Abuse
