I have tried looking this up but can’t find one that looks like this model. It’s installed in the second level of a new build and is definitely venting to the exterior as viewed from the attic space. I didn’t see and identifiers other then the Honeywell logo.
What is the model # of the Honeywell unit?
Do you have a picture of it from the attic?
Did it have a condense drip line, etc…could it be AC?

I couldn’t find a model number on it but I didn’t take the cover off, it was one of those ones with the springs on the side that are a pain to put back on. I didn’t see any condensing drip.
I don’t think it’s part of the AC. It seemed to vent directly above, I couldn’t get close in the attic because space was limited and the insulation was pretty high and I didn’t want to condense it. The home is very high efficient so I was wondering if it might also be part of a pressure stabilizer.
Just found out what it is. It’s an EVR filter. The owner had it in their warranty video. Learn something new every day.

A Bing photos search comes up with the same thing.

Bing? Is that still a search engine?
Sometimes all it takes is the basic to come up with the information that you are looking for.

That’s true. I googled it but nothing came up but I am not afraid to ask questions even if they are dumb ones haha. The owner ended up finding out what it was and text me. Usually the other way around. Just glad I found out so I know what to look for in the future.

Note: It’s an ERV, not a EVR.
Also, it’s a ‘Spot’ versus ‘Whole home’ application.

This is the first time I’ve seen a spot ERV, thank you for the correction, which is why it through me off. I’ve seen a lot of the whole home ERV in some high-end homes and they are pretty obvious and in a utility room or basement but this is the first time I’ve seen in a standard home. It was also covered in the attic by insulation. Larry was right!
Thank you for all your wisdom and knowledge guys!

Good call, Jeffrey. I would have posted the same thing.
Energy Recovery Ventilator/ion Unit.
What I do not see is the duct work in the attic or wall vents. It is not a ductless unit. Should be 2 insulated ducts in the unconditioned attic space, at the minimum. From the manufacturer, Panasonic. ( ERV uses two (2) 4" inch ducts - one to exhaust stale air and the other to supply fresh air from outdoors.
Should spot 2 wall vents high on the exterior wall or the soffit. Those smaller ERV units do the same as the larger/bigger ERV’s or HRV’s units we run into on modern homes only smaller.
Good call.
