for forced hot air furnace.

Pros & cons of the cheap throw aways versus the more expensive ones you wash.

the really cheap fiberglass vs. the pleated.

Is there any benefit to charcoal odor eliminators (when there is just normal household odors) --72.70.xxx.xxx

furnace filters (by 6x6 [TN]) Posted on: Jan 11, 2019 9:25 AM

In my SFH my tenants recently moved out of I changed the filter every 2 months. I used the pleated ones at first but then switched to the cheaper fiberglass ones and have had no problems. It is funny because these guys were slobs but the filters were going two months easy and I know it was the same filter I put in. If they were smokers or had pets I would use the pleated from Home Depot at about $9 for a pack of three and change every months. I don't want my 5k unit to brake. Don't use too thick of a filter or the unit can't breath and will brake. Hope this helps. --73.120.xx.xxx

The washerable ones are not that good at filtering. I use the low priced pleated ones. --99.23.xxx.x

I use the cheap fiberglass ones and have my helper change them monthly. Gives us a reason to have him inside every unit on a regular basis. --166.137.xxx.xxx

I prefer pleated...but towards the lower end of price. For rentals any MERV rating is ok, but in my personal home I use a MERV of 8 or higher. I change about every 2 months...some of my units' filters are filthy after 2 months and some are not...don't think it's the tenants but not sure why some get dirty faster than others....maybe SCFM of the blower unit causes more air exchanges on some units.

Don't know about odor eliminators.

I will tell one story...

I have a 1960s unit with a 2014 furnace. The new tenants moved in 2017 and said the furnace was not working right. I went over there and did not find anything wrong. They said it kept "cutting out"...then restarting on it's own...what I call "short cycling". After some investigation, I found they had put one of those really restrictive allergy filters in without permission (our lease says only I change filters). They said they prefer these. I told them that's probably what's causing the problem...they said I was crazy. I said "I'll tell you what, I'll call a professional HVAC person and if they say the same thing, you will pay for the service call." They agreed, and sure enough the pro said the same thing. They paid the service fee and went back to my standard filters. This was a unit with only one air return...you don't want to restrict them too much. --99.92.xxx.xxx

By the way I've never been a fan of washable filters...they just don't filter very much IMO. --99.92.xxx.xxx

Our HVAC techs recommend the cheapest filter we can find and replacing more often. Like once a month. --50.82.xxx.xx

furnace filters (by Gene [OH]) Posted on: Jan 11, 2019 11:48 AM

In my own personal residence, I have used the cheapest filters for about 35 years and the furnace is still doing a great job. We did have to replace the motor once during that time. The longer they are in the more effective they become, so I change the filter every 2-3 months depending on how dirty it is. --155.188.xxx.xx

furnace filters (by Ken [NY]) Posted on: Jan 11, 2019 12:01 PM

I use the cheap ones,i buy enough to leave right at the furnace to last a couple years then during heating season I change them or a handyman does when he is there roughly monthly.The most important thing is that they get changed occasionally,a friend of mine owns a heating company and he gets calls regularly for no heat where the problem is that the filter is so dirty no air can get through and it creates an emergency and a bill for a service call --72.231.xxx.xxx

furnace filters (by Ponari [TX]) Posted on: Jan 11, 2019 1:00 PM

Our hvac gut told us to use cheap. We were using expensive ones and he said they were too thick - the units were struggling. --47.188.xx.xx

furnace filters (by gevans [SC]) Posted on: Jan 11, 2019 4:27 PM

HVAC tech here. Use the cheap ones and change them often. The thick or high MERV filters are only good if your system is actually designed for them...and few are.


furnace filters (by Ed [PA]) Posted on: Jan 11, 2019 4:33 PM

I found it difficult get the reusable ones clean and tenants certainly won't clean them. For rentals I use the cheapest, for my home pollen grade filters but not the really thick ones. --71.112.xxx.xxx

furnace filters (by fred [CA]) Posted on: Jan 11, 2019 6:33 PM

Use the 99c filters and change them often. --99.59.x.xxx

furnace filters (by AllyM [NJ]) Posted on: Jan 12, 2019 7:29 AM

Several heater guys have told me that the expensive pleated ones will burn out the motor faster. They just use the fiber ones, blue or white here --73.248.xxx.xxx

furnace filters (by Robert J [CA]) Posted on: Jan 12, 2019 9:39 AM

I provide my tenants upon move-in with a case of six replacement furnace filters. I sometimes buy the filters with whistles. When the filters get clogged the air passing through the whistle starts to sound off letting them know it's time to change the filter. --47.156.xx.xx

furnace filters (by Ray-N-Pa [PA]) Posted on: Jan 15, 2019 5:30 AM

I use the cheapie ones and put two frabreeze sheets on them to circulate that fresh linen smell around. It works alright for a few days. Don't screw up that hack and put the sheets on the wrong side of the filter --72.23.xxx.xx
