Recalls, humidistats, noise and upkeep
Updated
Check the model number of any dehumidifier you own, old or new, in the recall search at cpsc.gov. Millions of units have been recalled for overheating and fire risk, across many well-known brand names. Then buy a small separate humidity gauge, because the readout on the unit is often off by several points.
Recalls: check the one in your basement today
I searched the Consumer Product Safety Commission recall records on September 18, 2026. These are some of the dehumidifier recalls on file, by date and title. I am listing them so you know how common this is, not as a full list.
- September 2013: Gree recalled 12 brands of dehumidifiers for serious fire and burn hazards. The recall was expanded and reannounced in 2014 and 2016. The 2016 notice cites 450 fires and names Frigidaire and Soleus Air among the brands.
- November 2016: dehumidifiers made by Midea were recalled for serious fire and burn hazards.
- August 2021: two million dehumidifiers made by New Widetech, sold under well-known brand names, were recalled for fire and burn hazards.
- August 2023: Gree recalled 1.56 million dehumidifiers for fire and burn hazards, with reports of at least 23 fires.
Most of these cover units made years ago. That is the point. Dehumidifiers get handed down, left in rental basements and sold at yard sales. None of the recall titles I read named the seven models on my list. But titles do not show model numbers, and recalls are added all the time, so run your own search.
- Find the brand, model number and date code on the sticker on the back or inside the bucket bay.
- Go to cpsc.gov, open Recalls, and search "dehumidifier" plus the brand.
- If yours is listed, unplug it and follow the recall notice. Do not keep using it.
Basic fire sense
- Plug it straight into a wall outlet. No extension cords or power strips.
- Give it the clearance the manual asks for on all sides, so air can move.
- Clean the filter on schedule. A starved fan makes the machine run hot.
- If it smells hot, trips a breaker or the plug feels warm, unplug it and stop using it. Electrical questions belong with a licensed electrician.
Why the humidity readout is often wrong
The sensor sits inside the unit, right where the driest, warmest air in the room is. So the display tends to read lower than the far corner of the basement really is. Sensors also drift with age.
- Buy a small digital hygrometer and put it across the room, away from the unit and off the floor.
- Trust the hygrometer. If the unit says 45 and the gauge says 55, set the unit lower until the gauge reads what you want.
- Aim for 45 to 50 percent. The EPA suggests staying below 60 percent, ideally between 30 and 50.
- If the unit runs and the bucket stays dry while the gauge reads high, the unit may have failed. Several owner summaries I read mention units that stopped collecting water. Use your warranty.
Noise: what to expect
A compressor dehumidifier sounds like a window air conditioner on low: a fan, plus a compressor hum that clicks on and off. Makers rarely publish noise numbers you can compare. Of my picks, only the Waykar listing gave one, a claimed 42 dB. Owner summaries for the Midea Cube, the hOmeLabs pump model and the AlorAir HD55 were split between quiet and noisy.
- For a bedroom, run it during the day and let it rest at night, or pick a size up so it reaches the target sooner.
- Set it on a hard, level floor. A unit on a hollow platform or uneven tile will rattle.
- The Ivation Desiccant and the Pro Breeze Mini have no compressor, and owners call both quiet. Both are for small spaces only.
Upkeep checklist
| How often | What to do |
|---|---|
| Every time you empty it | Rinse the bucket |
| Every 2 weeks | Wash the bucket with mild dish soap. Rinse the filter, let it dry, put it back |
| Monthly | Check the drain hose for kinks, slime and low spots. It must slope downhill all the way |
| Each season | Unplug it and vacuum dust off the grilles. Search the recall database again |
| Before storage | Empty and dry the bucket, drain the hose, store it upright |
When a dehumidifier is not the answer
If you can see mold, smell it strongly, or someone in the home has breathing trouble, talk to a qualified professional. A dehumidifier helps keep dampness down. It does not clean up mold that is already there, and this site is not medical advice. If dust, smoke or pollen is the real problem, that is a job for an air purifier, which our sister site Right Size Air covers.
