What size unit do I need for my house?
The sizing chart below will help you determine which AprilAire dehumidifier is best for your home, but please consult with a Healthy Air Pro before making any purchases.
Sizing recommendations are based on homes with tight envelopes and forced air systems that complete 0.5 ACH (air changes per hour). In regions with high humidity, homes will require dehumidifiers to remove more moisture from the air. This will require the use of a higher-capacity AprilAire dehumidifier. Please contact your local Healthy Air Pro to help you find the right dehumidifier for your home.
|Crawl Space||Small Home/Basement||Whole-Home/Basement||Whole-Home/Basement|
|Up to 2,800 Sq. Ft.*||Up to 3,800 Sq. Ft.*||Up to 5,200 Sq. Ft.||Up to 7,200 Sq. Ft.|
|70 Pints/Day||70 Pints/Day||95 Pints/Day||130 Pints/Day|
*The maximum square footage associated with the Model 1820 pertains to just the area of a crawl space and not the whole home.
How often do I need to change the filter?
The filter does not need to be replaced. It is a cleanable filter and should last the lifetime of the AprilAire dehumidifier. After installation, the air filter should be cleaned every six months. The CLEAN FILTER service reminder will display on the on-board control screen every six months as a reminder.
If the filter is damaged, you can purchase a replacement at our shop.
Filter Cleaning Procedure
- Turn the ON/OFF switch OFF.
- From either side of the dehumidifier, remove the filter access door.
- Slide the filter out of the dehumidifier.
- Flush the filter with warm water and a mild detergent solution.
- Shake off the excess water from the filter.
- Place the newly cleaned filter into the unit, making sure the filter is secured in both the top and bottom filter rails.
- Replace the filter access door.
- Turn the ON/OFF switch ON.
- Press the UP and DOWN buttons simultaneously for 3 seconds to clear the service message.
Display Codes on Your AprilAire Dehumidifier
Please note: When your dehumidifier is displaying a code, it has stopped working. Please contact your installing Healthy Air Pro to remedy all display codes except E8.
I’m seeing an E2 on my dehumidifier’s display. What does E2 mean?
An E2 code means high refrigeration temperature. There are several reasons for an E2 code, but high refrigeration temperature generally results from poor airflow through the dehumidifier which could be a result of a dirty filter, restricted air ducts, or a fan experiencing some kind of mechanical issue. To remedy this issue, please contact your installing Healthy Air Pro.
I’m seeing an E3 on my dehumidifier’s display. What does E3 mean?
It means that your AprilAire dehumidifier has been configured to look for a Model 76 Digital Wall Mount Dehumidifier Control and it cannot locate one. Either the setting is wrong or the Model 76 is not reachable. To remedy this issue, please contact your installing Healthy Air Pro.
I’m seeing an E4 on my dehumidifier’s display. What does E4 mean?
This means your AprilAire dehumidifier is having a difficult time reaching its desired set point. To clear this code, turn off the power to the dehumidifier using the ON/OFF switch, which is located near where the power cord enters the dehumidifier. You can also unplug the dehumidifier. If the problem persists, contact your installing Healthy Air Pro.
I’m seeing an E7 on my dehumidifier’s display. What does E7 mean?
It means that the float switch safety is reading a fault mode (open). Check the float switch connection at the control board. If you are not using a float switch, verify the jumper is between float switch terminals on the dehumidifier control board. To remedy this issue, please contact your installing Healthy Air Pro
I’m seeing an E8 on my dehumidifier’s display. What does E8 mean?
It means that the incoming air conditions are out of range for dehumidification. It is self-correcting. The E8 code will display if the incoming air temperature is below 50°F or above 104°F. The code will also display when the dew point is below 40°F. When the incoming air is within the acceptable range, your AprilAire dehumidifier will resume operation.
Does my AprilAire dehumidifier come with a drain hose?
Can I run my AprilAire dehumidifier in the winter?
Yes, if the air temperature is 50°F or above. Otherwise, you may see an E8 code display.
