What are these?

Hey gang,

Saw something today that was a first;

On some duct work in a crawl space, saw these two, large…“pods” in line between the furnace and a vent for a bedroom at the end of the run. There is nothing between the furnace and the vent except for these “pods” and maybe…30ft of duct work; straight shot too. There are no wires (I was thinking some kind of inline fan to help push the heat) or valves or anything other than these two “pods”.

I have never seen anything like this. Any ideas?

I can think of only one thing and that is additional filtering for ASTHMATIC in the bedroom.

Nice look at that I have only seen this on exhaust not supply for Lennox units.
About time someone came up with this design or has it been here awhile but I have never seen it in Inspections.

Thanks for the feedback guys;now I know. I thought the homeowner was getting creative and installed some glass pack mufflers from his hot rod!\:D/

I think the manufacturer of the muffler product is missing a great marketing opportunity by not labeling the product. Put a name on it and make it easier for us guys in the field…and maybe sell more product. Sorry guys…January is marketing month for me so sales is on my mind.

Good idea I sent them a letter …Roy
