How to Get Rid of Dehumidifier Smell
A musty smell from your dehumidifier comes from the water bucket, where standing water sits and grows mold and bacteria, and the machine then blows that smell back into the room. Empty and clean the bucket, wipe the filter and coils, and empty it regularly, and it clears.
We make small-batch beeswax candles in Far Rockaway, so a room that truly smells clean is our whole focus, and that always starts at the source rather than the scent. Below is where the smell comes from, how to clear it step by step, and how to keep the space fresh afterward, with the full the MBur beeswax candle collection here as you read.
Why a dehumidifier smells musty
The whole job of a dehumidifier is to collect water, and that water sits in the bucket, warm and still, which is ideal for mold and slime. If you do not empty it, or it drains slowly, it grows.
The fan blows air past that bucket, so the smell spreads through the room, and the filter and coils collect grime too. Cleaning the bucket and filter is the fix.
How to clean it, step by step
- Empty the bucket. Pour out the standing water.
- Wash the bucket. Scrub it with hot soapy water and a vinegar solution to kill mold and slime, then rinse and dry it.
- Clean the filter. Remove and rinse or wash the air filter per the manual, and dry it before it goes back.
- Wipe the coils and grille. Gently vacuum or wipe the intake grille and coils to remove dust and mold.
- Drain it properly. Empty the bucket regularly, or set up continuous drainage with a hose to a floor drain so water does not sit.
Continuous drainage solves it for good. If you can run a hose to a drain, the water never sits in the bucket long enough to grow the smell.
Keep it from coming back
Empty the bucket often, or use continuous drainage, and clean it and the filter regularly.
Run the unit in a ventilated spot, and empty and dry it fully before storing it.
Freshen the whole room once the source is gone
With the moldy bucket handled, the air itself is the last step. A clean candle is the finishing touch here, best lit once the space is already clean. From there it is the fastest way to make the room read fresh rather than merely neutral.
For your home, Just to Clarify fits well. It is clean and crisp, with bergamot, lemon, and green tea, and like every MBur candle it is poured from 100% beeswax with a wooden wick and phthalate-free non-toxic fragrance oils, so freshening the air never means adding soot on top.
