What's the Quietest Aprilaire Dehumidifier?

[@elenay.9536]

Hi. Thank you for the video. Where did they measure a noise level? Is it 45dB right next to dehumidifier? 10 Ft away from it in the crawl space? is it in a room right above it? What floors? Also, what about the noise from the the blower and pumps? Subfloor vibration?

I am sorry I do not know the answer to those questions. I was not involved in the testing.

Thank you!!

I was told by an installer that adding ducting would make the dehumidifier unit less efficient, making it work harder than necessary. Is this true?

[@CrawlSpaceNinja]

Not if its within the Dehumidifier's coverage. This is a common practice with dehumidifiers designed for Crawl Spaces and Basements

@@CrawlSpaceNinja Thanks; I had my doubts. I need ways to reduce the sound decibels significantly. I'm thinking only 4 or 6 feet, not 20 or 30 feet. Should I put the ducts on both the exhaust and the intake or just one or the other? What else can I do? Wrap the unit in sound attenuation of some sort or would that make it overheat?

I'm sorry but we don't at this time.

dang I managed to get the loudest one... it's in my unfinished basement a d I definitely notice it.. I'd be interested in a video about ducting basics when you aren't doing standard wall registers.. I'd like to quiet things down even though I don't technically need vents in any particular location.

Although these machines aren't quiet by nature, we can still reduce the noise they produce with the help of some common materials. A tried-and-true method is to use plywood and carpet or high-density foam together. You can create your own dehumidifier platform if you purchase a small 2x2 piece of plywood, some simple carpet, and a stapler. This absorbs vibrations as well as dissipates noise. Alternatively, you can purchase a block of high-density acoustic foam. Vibrations move through the casing of the dehumidifier, which is why this works so well. If a surface is too hard, off level, or the legs of the dehumidifier are not touching the floor evenly, the vibrations continue (from the motor down to the base). In this case, acoustics work very simply. Carpet and high-density foam are soft, absorbent materials that spread noise over a large surface area, leaving only the humming noise of your dehumidifier.

The location im planning to put the dehumidifier id directly below my bedroom. Will i be able to hear one of these when they kick on at 3am and im trying to sleep?

[@CrawlSpaceNinja]

It is possible that you will hear it turn on. If not the dehumidifier then possibly the condensate pump as it clicks on and off. It would be better if you could move it away from the bedroom.

[@canonman223]

When you say they're quieter when the dehumidifier is "ducted", do you mean ducted with flexible duct that has fiberglass in the sleeving? Or straight metal duct? Or plastic duct?

[@CrawlSpaceNinja]

DavidJ - Michael is referring to the 9" HVAC Insulated Duct that fits the collars.

@@CrawlSpaceNinja thanks!

Flex duct absorbs sounds coming from within the unit. Kinda acts like a supressor to absorb sound. You should pull it tight to minimize static, & switch to hard duct when passing through walls to seal it best.

How does one determine what size Aprilaire unit to purchase? I have 2600 sq. ft. ranch home with high humidity in the warmer months, some wetness on the northside cinder blocks, & no water/flooding ever in the basement.....

[@CrawlSpaceNinja]

Hey RJ, normally you will base your dehumidifier needs on the square footage of the crawl space. Here is a video we did comparing all of the Aprilaire dehumidifiers we carry and should help you determine which one will fit your needs. kzbin.info/www/bejne/ZqfacoKfnrx5r9k

I have a question. I'm looking to monitor my crawlspace humidity levels. I currently have an AprilAire E-080 and separate battery operated wireless humidity sensors that I have to replace 4x year. Is there a humidity monitor with a 10 - 20 ft cord that I can leave in the crawlspace and have the monitor in the house ....so I don't need to keep going into the crawlspace unnecessarily...just to change batteries. Thanks.

[@CrawlSpaceNinja]

What we do have is a Aprilaire Wifi Thermostat that is installed in the crawl space but you can monitor your dehu via the Aprilaire App! Here is a link - diy.crawlspaceninja.com/aprilaire-s86-wmupr-programmable-wi-fi-thermostat-multi-stage-universal-with-iaq-control/

I will have a 70 next week. Hope I cannot hear it in house. Painful hearing? Try a T37 trainer air craft. Took a lot of my ears in 1960s!🦇

Yikes! Hope the best for you
