Need to know what filter i need for furnace

This is probably not a factory specified size. You need to look at the return to your furnace. There should be a frame or housing for the filter. Measure it to see what size you need. These are often customized by the installer to meet the configuration of your ductwork. You need to measure how tal and how wide, but also how deep (thick). If possible always get a pleated filter, and not one of those "horse hair" cheap ones.

What size filter do I use

Look for any tags on the unit, many times they will list the size needed. Otherwise, you will need to break out the tape measure and see what it says. Filter sizes are a little iffy, so you most likely wont find the exact size, it will tend to be off by a 1/2 inch or so.

Recommend a washable lifetime filter that can be custom fitted for your unit. There are many different brands of cut to fit and custom sized filters available.
The original filters supplied with the unit are usually washable as well although the manufactures are not including it all the time anymore.

I need to replace the air filter on this unit and I can't find the right size filter. What size do I need? I ave an Armstrong model # 64HWC303a-2B Serial # 8401H12194

If it's a plastic mesh filter, you can buy an uncut kit at most home centers and hardware stores. That you can cut to fit your unit.You'll probably have enough left over to make 2 filters.

Filters for a rudd model # rkkb-a120cm22e

get a tape measure and measure it. lets say the size is 20" x 24". the filter size will be 23 1/2" x 19 1/2" why they do this i dont know.

if it is a real old unit just go to publix or walmart (publix is only in florida) and get one of those crappy blue filters that you hose out. you can cut it with sicsors and it fits underneath that crappy metal u wire.

if you have the unit i think you should just run the old blue "hog's hair filter" it sucks but so does your old unit.....

Changing Air Filter

In general terms an electric unit uses a 20 x 20 x 1 filter and a gas system uses a 20 x 25 x 1 filter. If the return filter is somewhere other than at the unit, it will very greatly in size. Its the descretion of the installer as to what size filter they choose to install.

How do I find the filter on a lennox G8Q3904 furnace?

If you don't have a filter "rack" installed then you have to remove the blower housing door. Usually the filter is there if it is not located in the house where the return air supply is. Some units have a filter in what is called a return air filter grill. If there isn't a filter already installed in the unit then you will have to measure the inside dimensions and then use one that is similar in size. It's not imperative that you use the exact same size. You just want to cover the opening of the unit. If you don't have central air conditioning, then it's not necessary to use a filter.
