How to quiet a dehumidifier

Oct 04, 2006 Last reply: 6 years ago 24 Replies

I have put a dehumidifier in my basement to take some of the dampness out of the air. The problem is I can only run it during the day because my daughter's bedroom is in the basement and the dehumidifier is really noisy. Does anyone have a creative idea for quietening it down? (It's already on a carpet). Thanks.


I live in NJ and in my town bedrooms in the basement are not legal.

Build a plywood box around it. Line the box with carpet or some other soft material. Leave a few decent sized (3" ?) holes in the box to provide airflow.

That would help reduce the noise, however it could create a hazard. That could cause the unit to overheat, also it would not have adequate air circulation to dehumidify.

In addition to potentially overheating, it seems like it just wouldn't work as well, unless it had a really strong fan to circulate lots of humid air in through those 3" holes. The whole point is that it needs to pull in the humid air, pass it over cooling coils, and blow out dry air, which would not work well in a box. The air inside the box sure would be dry, but I have doubts about the rest of the basement. My advice: if it's a specific part of the dehumidifier that's rattling/vibrating, see if you can glue/clamp/rubberband/tie that part so it doesn't vibrate. If it's really the motor making all the noise, there's a chance that bearings could be bad or the fan blades could be unbalanced or something like that, but unless you're a confident DIYer, it would probably be more expensive to fix than it's worth. Try a new dehumidifier - pay attention to the return policy and try it for a week. Good luck, Andy

To the OP: Get a heavy duty timer. Shut the thing off during certain hours. Your daughter's entitled to silence when she's sleeping.

I live in Victoria, British Columbia, Canada and they are legal here. Maybe you should move.

Of course my daughter is entitled to silence when she's sleeping. That's why I want to know how to make the dehumidifier quieter. If it's running all day and then off at night, I'm just wasting energy as the humidity builds up when the dehumidifier is off.

1) If the basement's so damp that you notice buildup with the dehumidifier off for 8 hours, you should find the source of the humidity and deal with it. 2) Unless the basement's got VERY serious problems, dehumidifiers will run often when you first install them, and then run less as the various objects in the basement dry out (walls, rugs, stored items). This stabilization period can vary quite a bit depending on what's actually holding the humidity (besides the air itself). The bottom line is that you may notice little or no difference in comfort between running the thing all day, and shutting it off at night. 3) If you want to quiet the thing, build a box around it. Wood lined inside with carpet. 3 sides and a top. 1 side open.

Is it fan-noise or rattling thats the issue? The best solution is to find a quieter model dehumidifier, but failing that, gluing something heavy to the sheet metal may (or may not) help. Is the machine IN the bedroom? Can you do something about reducing the noise going through the wall/door?

If it is a Kenmore, don't worry. It will break in about 1 year and then it will be quiet. I am on my 3rd.

One of the great humors of this newsgroup is the number of people who assume that their local zoning is pretty much universal. As you have pointed out, that just isn't true.

In our area, the major zoning requirement for a basement bedroom is that two exits must exist. One exit is generally the stairway to the ground floor. The second exit can be a direct exit "to daylight", a window which qualifies as an "egress window", or a second stairway to the first floor.

My news server lost the OP's original message, so the thread began with "Re:" messages.

By the way: Please learn how to reply correctly within a newsgroup thread. Bottom post so your messages read in the way that's expected by the vast majority of literate people on the planet. It's not that difficult to do intelligently.

That last is mildly odd. The model codes require the separate means of egress to be separated by a fire assembly, (or something like that), meaning that a second stairway leading to the garage would be OK, but on set of stairs to the kitchen, and another one to the family room wouldn't be. (Unless the house is strangly constructed).

Apparently, the idea being that a fire that starts in one place shouldn't be able to block or smoke out both exits unless it's been burning for more than an hour.

Pulling the plug works best. You will barely hear it when you do.

You mean it won't emit the "death rattle"?
