furnace filter - DIY Chatroom

coldintx · 11-08-2009, 11:32 AM

Hello,

I just moved into a rental that has a Snyder General natural gas furnace as its heating source. The year of manufacter printed on the the data label is 1985 and I believe the company is no longer in business, or was bought out by Arco furnaces.

Problem is that there is a replaceable cartridge type fiberglass filter in there now & is not the correct one, and is the wrong size to boot. Also, this unit is so old, I don't think it takes a cartridge filter.

If anyone has any information as to which type of filter this unit takes I would greatly appreciate it.

Here are the specs on the furnace:

Manufacturer: Comfortmaker by Snyder General
Model: G-U 400050-08M
Date of Manufacture: 10-85

Thanks for the help.

You could always try the NaturalAire cut-to-fit air filter sold at Walmart.

That's what I plan on doing if I can't find the correct filter type that's supposed to go with this unit....if it's even made anymore. I was hoping that I could use the throw-away type instead of the cut ones, like you mentioned. Thanks for the suggestion.

If you do go the cut-to-fit route, I suggest cutting a metal coat hanger to the width of the determined filter size and weaving it into the filter material. This helps support and prevent the filter from being sucked up into the system. I use this filter and have three evenly spread out metal rods weaved into the filter for support.

Good idea. That's one of my concerns without there being a filter track to secure the filter....that the in-flow of air will lift up and go around the filter rendering it ineffective.

Thanks again for the help.
