I would get one of these if I were sure it would fit our Atwood Air Command unit. Have reached out to the company but not heard back yet.
Our unit is quieter than our previous AC but still too loud for my wifes' comfort.

I'd love to know how much this reduces overall cooling output. If I understand it correctly, it is simply a CFM reducer.

I don't think it reduces the CFM at all.

It works by adding a channel with sound absorbing sides to the return air side of the AC unit.

New member here.

My Dometic roof mounted non-ducted ac that came with my 2016 camper trailer is very noisy. I can't sleep well.

I installed a 1-ton ductless mini split inverter heat pump and problem solved. It was very quiet.

Man, you can't even imagine how familiar this problem is to me! I also wasn't allowed to use our air conditioner at night because of the noise that my neigbours couldn't bear and I totally underastand them.
I mean, I'm a heavy sleeper, so it's really hard to wake me up at night, but it was also really uncomfortable for me, especially during the summer when I couldn't keep the air conditioner on at night.
So I decided to buy a new one but wanted to opt for something cheap and at the same time quualitative. I found a good Toshiba air conditioner on the socool.sg site.
By the way, they also provide repair services, so if you don't want to buy a new one you can just ask them too help you repair it.
Hope this helps!

We have a ducked Dometic heat pump and installed the Dometic version of this sound reducer. I believe it was less than $50. It too does away with the rapid cooling vent and adds some sound deadening to the input area. Easy install and made a noticeable difference in overall noise level.

Gary can you please post a web link to this or some other information so that we can have a look and possibly order one as well.

Thanks,
Rob

Rob,
This is what I ordered from Amazon in 2018 based on this statement I found on irv2. Although it doesn’t specifically say, it did include a metal plate and some adhesive sound deadening.
“ While we were at the THOR diesel Club rally in Goshen, the Dometic rep told us that if we switched out the air return cover to the basic one (no grill opening for the blast of air) it would be much quieter.

Just did it and it is much better. Costs about $50 from Amazon. use search term Dometic
3105007.045.”.
Here is the link to the actual one I ordered.

It makes the air take a less direct path and that path is lined with sound absorbing material. The air filter is larger and might allow more flow. As far as I can tell there is no reduction in air flow or cooling. I did add a couple of extra vents to my ductwork to be sure that I could get enough cool air where I wanted it. In my opinion system performance is improved.
