Frequently Asked Questions
Eva-Dry model numbers are based on the maximum amount of cubic footage (L x W x H) the unit is designed to work within. Only the EDV-4000 model has the option to change modes based on your targeted RH%.
The EDV-4000 rotary desiccant technology is a more powerful compressor-less way to dehumidify that doesn’t omit the GWP gases that a compressor-based unit would since they use coolant. The EDV-4000 has a greater absorption rate than Peltier technology and works in the widest temperature range of all our electrical dehumidifiers.
Eva-Dry’s electric models are covered by a 1-year warranty, but like most electric products it depends on the preventative maintenance as to how long they will last.
Keeping the unit dust-free is important, as dust accumulation will cause the internal parts to have to work harder and can cause power cord failure over time. To keep it in optimal performance we recommend using compressed air quarterly to dust the outer vents and inside components to prevent and clear out dust accumulation. Make sure prior to using compressed air to clear the unit, turn off and unplug the unit, and remove the water reservoir.
Silica gel renewable models (E250, E333, E500, EDV365AD) do not require any power during the dehumidification process, only during the renewal process. The units use 22.5 Watts.
The Peltier models (EDV-1100, EDV-1200, EDV-2200, EDV-2400, & EDV-2500) vary from 22.5 watts for the EDV-1100 & EDV-1200 to up to 72 watts for the larger sizes. The EDV-4000 unit uses rotary desiccant technology and depending on the mode selected will use from 330 watts on low to 615 watts on high.
Next, know the size of your space, so that you can select a unit large enough to properly handle the area you’re trying to dehumidify. Since you are dehumidifying the entire room and not just the floor space, we advise you to know the cubic footage (L x W x H) of your space, not just the square footage (L x W).
Lastly make sure you’re selecting the proper type of technology to be able to meet your RH% goals for the space based on the atmospheric conditions.
Product Specific, Eva-Dry FAQ's
We recommend every 30-90 days to clean the unit with compressed air. Turn off the unit, unplug, remove water tank, and blow compressed air in all the vents and then up in where the water tank slides in to remove any dust that may have accumulated inside the unit during operation.
The indicator beads take up less than .004% of the beads in the unit, and are not the beads that do the dehumidification, they simply are intended as an indicator. The indicator beads have a chemical added to them that allows them to color change, and are separated from the clear working beads inside the unit. The color chemical added to the beads is sensitive, and may be affected by vapors in its environment (i.e. fragrances, cleaning products, metals, etc.).
Additional questions
The renewable units do not need to be cleaned, aside from occasional wiping with a damp cloth if the shell becomes dirty.
For the electric units, we recommend using compressed air quarterly throughout the year to dust the inside of the unit. Dusting is to be done while the unit is off, unplugged, and with the tank removed. Spray compressed air in the vents and up to where the water tank slides in to remove any dust accumulation from the fan and blocks inside the unit.
As for the water tank, use a mixture of baking soda and white vinegar mix to clean away any build-up that may form inside the tank. Start by adding the baking soda first then add the vinegar. The foaming action created will clear away build-up from the walls and bottom of the tank. You may also use a pipe cleaner for stubborn spots. We also sell replacement tanks if needed.
Although more than one unit can be used in your house if needed to reach the targeted RH%.
Electric models (Peltier and Rotary desiccant) also use heat to assist in drying air that is outputted from the unit, depending on the type of technology used. On the EDV-4000 the mode selected will determine how much heat is outputted from the unit during use.
If the EDV-2500 has a flashing blue light that is indicating a defrost cycle and the cool block inside has frozen. We recommend turning the unit off for an hour or two to defrost. Ensure this is done in an area warmer than 50°F.
If the EDV-2500 has a flashing red light the unit has an internal issue and you should contact customer support.
The EDV-4000 will have the LED light on when it has an internal issue.
The EDV-1100, EDV-2200, and EDV-2400 all have full light indicators separate from the power button. The EDV-2400 will have a flashing light when the RH% set on the humidistat has been reached.
A dehumidifier removes excess moisture from damp environments. They are usually used in the spring, summer, and through early fall when RH% gets high (above 60%). During these times you may smell musty odors, feel clammy, or start to notice mold and mildew. Keeping your relative humidity level below 50% will keep your spaces safe from moisture-causing issues that can also lead to health issues over time if left unattended.
