Notice to RV owners: Moisture is insidious. It can hide unseen in the dark depths of cabinets and lockers. Even small amounts can cause rust, mold and mildew to set in. The result can be anything from a blemish to the complete loss of an item. Air-Dryr from Davis Instruments is an inexpensive way to stave off damaging humidity.
Air-Dryr is engineered to operate 24/7. Plugged into a 110/120V outlet and placed as low as possible, it warms the damp air to above the dew point. As the dry air is released through the top vents, cool, damp air is drawn into the device and processed. For safety, a thermal cutoff turns off the device in the event that something falls on top of it and blocks the air flow.
Without any moving parts, Air-Dryr is completely silent. Its durable polycarbonate housing is built to withstand years of use. UL Listed, it’s completely safe to handle when plugged in.
Two sizes are offered. Air-Dryr 500 has a 70-watt heating element and handles up to 500 cu. ft., yet draws only 0.6 amps. It measures 14″ L x 5″ W x 4.5″ H.
With a 130-watt heating element, Air-Dryr 1000 takes care of up to 1,000 cu. ft. of space. Drawing only 1.1 amps, it is 13.5″ dia. x 4.25″ H.
You can find the Air-Dryr 5oo and the Air-Dryr 1000 on Amazon.

This is not a dehumidifier. It is simply a heater. Heating the air reduces the relative humidity, but does not remove water vapor. When the air cools to its original temperature, the relative humidity will be be back where it was to begin with.
I agree 100%, and the manufacturers answer to this does not answer anything. To reduce the water in the air the water has to go somewhere, and this device does not appear to remove any water.
I suspect this is just a simple heating element. Sort of like a 75-watt light bulb that doesn’t make any light. I would agree that it really can’t dehumidify anything, just raise the air temperature in its surrounding area by a few degrees.
I received a reply to your comment, John, from Dave Scott of the PR firm for Air-Dryr:
Hi, Bob,
John T. is correct that Air-Dryr is not a traditional dehumidifier. Air-Dryr’s simple, proven technology is an ideal “set and forget” alternative to a large dehumidifier with a tank that continually needs to be emptied. (It’s also a better solution than my father’s 60W lightbulb suspended from the ceiling and glowing all winter long!)
Air-Dryr and dehumidifiers both protect against moisture-induced damage, just in different ways.
A while back I remembered someone talking about packets of chemical for reducing moisture. When they were saturated you placed them in the sun to recharge. Does anyone remember this? I’m trying to find the product.
Hi, Elizabeth. Sorry for the delay in replying. Here’s a link to our article from last summer about the Moso Natural Air Purifying Bag. https://www.rvtravel.com/bamboo-charcoal-filled-bag-absorbs-odors-moisture-pollutants/ Thanks for asking. 😀 —Diane at RVtravel.com
