I think most here would say a 4 or 5" thick,Merv 8 or 10,pleated media filter is a great choice,and the minimum to keep the equipment clean.
what air filter does everyone use on there furnace?

Lennox HC16 - MERV 16 media
Also considered the Aprilaire ones...
i have been using the 3m 1500. i know a lot of people on here dont like them that is why im asking. i have looked at lowes all they hay is 3m and the cheap blue one were do you all get them from? my furnace uses the one inch thick ones.
I have the Honeywell MERV 12 4" media on mine.
I notice that Lowes don't have a good choice of filters, Home Depot has the good basic Pleated filter in a 3pk for about $6, MERV 8. Anything higher than that like the 3M is hard on your equipment.
I use a disposable fiberglass filter. We also use a vaccuum cleaner around the house once in a while.
Anything other than 1" will likely require some sheet metal modifications. Like Dash said, call a contractor. There are lots of choices in 4 and 5" models. Some of which can be bought at HD/Lowes (I think I saw an Air Bear there once). You can always buy replacement filters online for almost any brand. But you gotta get the unit installed.
Why do those people not like them? As far as I know, they'll restrict airflow and reduce system efficiency just as well as other expensive filters designed to make the hardware store profits.
If all you have is a single medium to small sized filter serving the system then it's likely that you don't have enough surface area to properly support a high efficiency filter. It presents more restriction than the system is designed to handle. Unfortunately, many systems don't deliver proper airflow even with a non-restrictive filter. They're only made worse by the addition of a 3M or anything like it. In other words, Doc may have been steering you on the right course.
Consider too that you're not really going to have any great impact on air quality unless you run the furnace blower 24/7 or at the very least on a consistent circulate mode. You'll also need to keep the house closed up all the time. If you're ducts leak a lot and in the wrong places then that impact could be negative rather than positive.
There are numerous assumptions in my reply regarding your situation, such as the assumption that you're goal is improved air quality. Obviously I could be wrong. Suffice it to say that for most people slapping an expensive filter into a furnace often accomplishes little of what they want and results in other things they didn't expect.

if all 3 filters are for 1 system you wont have problems using the 3m filtrete filter
IMHO,no,but at best the must be changed in weeks,not months.
