Air Dryers and Dehumidifiers Protect Your Boat from Mold and Mildew
Don’t let this happen to you! While the picture above is an extreme case of mold and mildew growth, the risk of humidity damage to your boat when in storage is not something to take lightly.
Boat air dryers and dehumidifiers are designed to lower the level of humidity in the air. By either absorbing water vapor or increasing the temperature so that water does not condense on surfaces, these products can prevent harmful mold and mildew buildup, odors, rot, and stains.
Check out this rundown of 3 different types of air dryers and dehumidifiers, and see which product works best for you:
Typical dehumidifiers work by soaking up moisture in the air and collecting it within water-absorbent crystals. Once these de-humidifiers are used, they must either be replaced, or the water-bearing crystals within need to be switched out. The Starbrite No Damp Dehumidifier bucket is a good example of these types of non-electric dehumidifiers, and can cover a range of either 900 or 1,800 cubic feet of space.
Pros: they are low cost, cover a good amount of space, and are widely available, functions in any environment.
Cons: the chemicals if spilled can corrode materials, and you have to dispose of older buckets and switch them out for new ones when they’re no longer of use.
An alternative to the typical dehumidifiers are the Eva-Dry Dehumidifiers. These battery-free, 100% reusable dehumidifiers are an eco-friendly way to prevent moisture damage. Silica gel crystals in the Eva-Dry Dehumidifier lock in moisture to eliminate odor and mildew that can cause damage to your boat. An easy-to-read gauge changes color as the unit saturates with water. Once the unit is completely saturated, you can easily remove it, plug it in a well-aerated area, and within 24 hours it will be dry and ready to use once more.
Pros: environmentally friendly, long-term usability, battery-free, functions in any environment.
Cons: there is some maintenance involved in checking whether the dehumidifier is full, and the time costs of recharging the unit to dry it out.
Electrical Air Dryers
Electrical air dryers gradually increase the temperature above the dew point in the environment. This prevents water from condensing on surfaces within your boat and creating mildew and rot. Electrical dryers have a built-in thermal cut-off switch that prevents units from overheating. These air dryers are designed for long-term use, and can be operated 24/7 for extended periods. Electrical air dryers like the DryWave 1000 Electric Air Dryer contain no moving parts that could cause sparking, and draw no more power than a light bulb. The DryWave units cover a range from 100 to 1000 cu. ft.
The best time to use electrical air dryers is during the fall, winter, and spring months when humidity is high and temperatures are between 32˚F and 65˚F. Air dryers work best when humidity is high and temperatures are cool, when conditions are perfect for the growth of mold and mildew.
Pros: low maintenance – plug it in and forget about it, covers a large amount of space, low energy expenditure.
Cons: needs access to electricity, does not work well in high temperature, high humidity areas.
Whatever product you choose, you can be sure that by using a boat air dryer or dehumidifier that your boat will be mildew-free and ready to sail when you’re ready to take your boat out of storage.
