Size Name: 500 cubic ft
I have this AND the larger mold-zapper - we live in a 35 year old building in a foggy part of San Francisco and without these two (1 in bedroom, 1 in living room) the mold build-up on the window rails in winter was just awful. These have made all the difference - including to our mold allergies. As a plus they warm up just enough to take the chill off the room, without being warm enough to be any kind of hazard. EXCELLENT product, totally worth it

We love ours so much that we purchased another as a gift for a friend. We use this in our motorhome to keep the pipes from freezing in the winter, keep the moisture down and keep our toes warm while camping. Uses very little electricity, just warm enough and no worries about fire hazard.
Wouldn't hesitate to buy again.

Size Name: 1000 cubic ft Verified Purchase
This review is for the 1000 cubic foot model , so measure your room .
Example 10X10X8 feet high = 800 cubic feet .
Works as described while using very little electricity .
With my electric rates this costs less than $6.00 a month if left on 24/7 .
No moving parts , nothing to empty , very gentle warmth ... hands down good deal .
This is not a dehumidifier , it works moving the air by convection .
Warm air rises , pulling moisture and drying out things along the way .
If your room is pretty well sealed , give it a try .
If your room is air tight go with a dehumidifier .
You'll need a little air exchange with the Davis ,
otherwise the heat and moisture will have nowhere to escape .
Most rooms are nowhere near airtight , so don't worry too much .
The lower to the ground the better , but raise it slightly .
18" inches is great , this will allow for ample ground air pull
and maximum rise creating a nice airflow column .
Keep the bottom as unobstructed as possible .
Since it already sits almost flush to the ground ,
I've put mine on a bucket with two 8 inch long two by fours
one each at 3 and 9 o'clock underneath the diameter of the unit
as close to the outside diameter as safely possible .
Block the bottom grate as little as possible , again to increase airflow .
Thermal dynamics baby !

We have used these dryers for years. AWESOME product. We have several collector cars that we put them in year round. We use them in them in our RV and in our closet with our leather motorcycle clothing. WAY better than using a light-bulb or heater. Would recommend them to anyone that has a moisture or high humidity problem.

Size Name: 500 cubic ft Verified Purchase
My mother has used these in her basement for the last 10+ years, and I'm currently using two of them in my basement. Between both houses never issues with moisture and no musty smell.

The Air-Dryrs definitely work as advertised, I don't know why more people haven't heard of them and why anyone would prefer to deal with a dehumidifier instead.

Totally safe for babies as well; my 18 month son keeps making his way over to see and touch it but the surface is just not hot enough to be dangerous.

The only serious danger this unit poses is if it gets covered (smothered) for an extended period of time.

Based on my history with these dryers, I have to give 5 stars.

Size Name: 500 cubic ft Verified Purchase
I was so impressed with this little dehumidifier I purchased two more. We live in a motorhome in a high-humidity part of Washington state, and the first unit was put below a window that never sees sun in the winter and has a lot of condensation. Now the window stays almost completely dry. The second unit was put under the front dash, keeping the windshield much drier as well. They aren't powerful units that dry areas completely, but will make about a 20% difference in a small high-humidity space. They use little power, and don't get hot enough to worry about leaving them on all the time. Definitely worth the money!

Had to wait a few weeks to see if it actually worked and it does. I have a space that is not air conditioned off my bath and it would smell musty in the summer or when it was humid. It seems to be working because it has been humid and I do not have the musty smell.
