Missing Parts and Lots of Dust

I went to change the furnace filter today. We have an early 80's Lennox furnace that uses a hammock style filter. This type of filter is basically a fiberglass sheet clamped onto a wire basket or frame that is inserted by the cold air intake.

Here are the instructions:


There is supposed to be a frame holding the hammock filter in place.

Here is what is actually IN my furnace:


It's just a 2'x3' sheet of fiberglass filter material shoved up there! It is free floating, and not attached or clamped to anything. No WONDER there is dust all over our house.

I called a few heating supply places in town; they don't sell to the general public, and don't even know if they can get the part needed.

Any ideas?

Can you make the part? I would try some wire fincing (not chicken wire) or some concrete wire, and fold it over to match the shape.

This kind of fencing

Got a wider angle picture? The house I grew up in had one like the drawing, and I remember my dad found a way to use "standard" 1" thick filters in it - the kind with the cardboard edging around 'em.

All things considered, if you can find a way to use regularly available filters you are much more likely to change the filters on a regular basis.

Hey Jen,
Your house inspector should have caught that. If you haven't had the furnace inspected since you moved in, DO THAT. They'll check to make sure you're not leaking CO3, that the heat exchanger is burning clean, and they'll replace the filter with the correct one. Will save you money in the long run.
A quick fix for the filter is to measure your space and temp. replace it with another. You can buy cheap ones at the hardware store--cut it to size.
But DO get the whole system looked over.
Much Love!

Jennifer- Muskego Jeff is right- I was talking to the HVAC Mechanic at work he suggested you measur and get 3 filters nad set them up this way:

HE said you then can use duct tape for the seams, and there ya go- a tripod "hammock" filter

Thanks Rob and Muskego Jeff~ We will try both of these to see what works! Thanks!

Barb~ The inspector didn't mention it... did tell us that the furnace was OLD but in good working condition. We'll ahve to get an inspector out here again.

Do you have an HVAC company that comes out regularly? Since our crap is so old we have them out twice a year to make sure it will all last another few months. They are pretty cheap (50 or 75 bucks a visit and they usually replace any missing screws, parts, etc. for a nominal fee. I think it's woth it. What's with that filter type? We have the same thing. I am skeptical that they do anything - but there is dust on it so I guess it is working.
