AprilAire Dehumidifiers: Which Whole-House Model Fits Your Home?

AprilAire has made indoor air quality equipment since 1954, and its whole-house dehumidifiers are a step above the plastic tank models you carry from room to room. These are larger, heavier units designed to sit in a basement or crawl space, or to be ducted into your home’s heating and cooling system, and they drain continuously through a hose so there is no bucket to empty. Every model here runs on a set point: you choose a relative humidity (RH), the percentage of moisture in the air compared with the most it can hold, and the unit turns itself on and off to keep it there.
The six models differ in capacity and extras: the E070 (70 pints per day), E080 (80) and E100 (100) come in plain Pro versions, Pro bundles with extra accessories, and newer W versions with Wi-Fi app control.

AprilAire E100W Wi-Fi Dehumidifier
Best for: Large homes up to 5,500 sq. ft
Pros
- 100 pints per day
- Wi-Fi and Bluetooth app control
- 6-year warranty
- ENERGY STAR Most Efficient 2024
Cons
- Heavy at 64 lbs
- Pump and hanging kit not listed
The AprilAire E100W Wi-Fi Dehumidifier is the top of the range: it removes up to 100 pints of moisture per day (PPD) and covers homes, basements or crawl spaces up to 5,500 square feet. Pints per day is the standard way to rate how much water a dehumidifier can pull from the air in 24 hours under test conditions, so a higher number means it can handle a bigger or damper space.
It connects to Wi-Fi and pairs over Bluetooth in three minutes or less, and the Healthy Air App lets you adjust it, see alerts and diagnostics, and receive updates from your phone. It offers top or end air discharge, an 8-foot power cord, R32 refrigerant (a type with lower global warming potential), and it is rated ENERGY STAR Most Efficient 2024. The warranty is 6 years: 5 years of full replacement plus 1 year of parts. It weighs 64 pounds and measures 14 by 26 by 15 inches.
This suits large homes and anyone who wants to check humidity remotely, such as owners of a second home. For a smaller house or crawl space, it is more capacity than you need.
AprilAire E070W Wi-Fi Dehumidifier for Crawl Spaces
Aprilaire
AprilAire E070W Wi-Fi Dehumidifier – 70 PPD for Crawl Spaces, Basements, Whole Houses up to 2,200 Sq. Ft., Part of the AprilAire Healthy Air System

AprilAire E070W Wi-Fi Dehumidifier
Best for: Crawl spaces and smaller homes
Pros
- 70 pints per day
- Wi-Fi app alerts and diagnostics
- Compact 12.5 inch height
- 6-year warranty
Cons
- Covers only up to 2,200 sq. ft
- Hanging kit sold separately
The AprilAire E070W Wi-Fi Dehumidifier is the smallest Wi-Fi model, rated at 70 pints per day for spaces up to 2,200 square feet. AprilAire describes it as the perfect solution for crawl spaces, and its low 12.5-inch height helps it fit under a house. It can be ducted with 8-inch flex duct or hard pipe, and hung from joists with the Model 5822 Hanging Kit, which is sold separately.
It shares the E100W’s Wi-Fi and Bluetooth app control, R32 refrigerant, 8-foot cord and 6-year warranty. The specs list 696 watts, 200 cfm of airflow (cubic feet of air moved per minute) and 56 pounds. It suits a crawl space or a smaller home. Larger homes should step up to an 80 or 100 pint model.
AprilAire E070 Pro Dehumidifier Bundle with Extra Accessories
Aprilaire
AprilAire E070 Pro Dehumidifier Bundle – 70 Pint Whole House Dehumidifier – Full Complete Kit – Crawl Spaces, Basements, Whole Homes, Commercial up to 2,800 sq. ft – 5 Year Warranty Included
Price and specifications are read from the Amazon product page and can change.
AprilAire E070 Pro Dehumidifier Bundle
Best for: Basement owners wanting accessories included
Pros
- Drain hose, 2 filters, risers
- 70 pints per day
- No water tray to empty
Cons
- No Wi-Fi mentioned
- Several specs look inaccurate
The AprilAire E070 Pro Dehumidifier Bundle pairs the non-Wi-Fi E070 with accessories: a drain hose, duct collars, two filters (one extra) and a set of dehumidifier risers that lift the unit off the floor. The listing says it removes 70 pints per day and covers up to 2,800 square feet, which is more than the E070W’s 2,200 figure for a similar 70-pint rating, so treat coverage as a rough guide.
It is ENERGY STAR certified, recognized as Most Efficient of ENERGY STAR 2023 in the description, starts automatically when humidity rises above target, and has no water tray: you run a hose or set it over a floor drain. It comes with a 5-year warranty. Some specs look wrong, such as a 70-gallon tank, 20 speeds and a 33-inch width, so we would rely on the features. The listing does not mention Wi-Fi.
This suits a basement or crawl space owner who wants the spare filter and risers in the box and is happy to set humidity at the unit itself.
AprilAire E080W Smart Wi-Fi Whole-House Dehumidifier with Pump Kit
Aprilaire
AprilAire E080W Smart Wi-Fi Whole-House Dehumidifier, 80-Pint Energy Star Commercial Dehumidifier for Basement, Crawl Space & Home up to 4,400 Sq.Ft. with Pump, Drain Hose, Hanging Kit, MERV 11 Filter

AprilAire E080W Smart Wi-Fi Whole-House Dehumidifier
Best for: Installs without a nearby floor drain
Pros
- Condensate pump included
- Hanging kit and MERV 11 filter
- Wi-Fi app control
- 80 pints per day
Cons
- 63 lbs to install
- Warranty length not listed
The AprilAire E080W Smart Wi-Fi Whole-House Dehumidifier is the most complete kit here. It removes up to 80 pints per day in homes up to 4,400 square feet and includes a condensate pump with bracket and tubing, a hanging kit, a drain hose kit and a MERV 11 filter. A condensate pump pushes the collected water up and out when there is no floor drain nearby, which is often the deciding factor in a crawl space.
It has built-in Wi-Fi for app control and real-time humidity checks. The specs list 612 watts, 185 cfm and 63 pounds. The description says it removes 80 gallons per day, which is a mistake; the title and specs say 80 pints. The listing does not state the warranty length.
Choose this if your space has no drain close by or you want to hang the unit, and you want phone control. Our AprilAire whole-house dehumidifier guide covers installation in more depth.
AprilAire E100 Pro Dehumidifier Bundle for Big Basements
Best for: Big homes wanting a spare filter
Pros
- 100 pints per day
- Drain hose, 2 filters, risers
- Corrosion-resistant aluminum coils
- 5-year warranty
Cons
- No Wi-Fi mentioned

The AprilAire E100 Pro Dehumidifier Bundle is the 100-pint model with extras: drain hose, duct collars, two filters and risers. It removes up to 100 pints (12.5 gallons) per day in homes up to 5,500 square feet, carries ENERGY STAR Most Efficient certification and uses corrosion-resistant aluminum coils. There is no water tray, and it starts automatically when humidity rises above your target.
It is designed and assembled in the USA and has a 5-year warranty. The listing does not mention Wi-Fi or state a weight, and one spec lists continuous operation while the features describe automatic on and off. It suits large homes that want maximum capacity with accessories included but do not need app control. If you want Wi-Fi and a longer warranty, the E100W is the alternative.
AprilAire E080 Pro 80-Pint Whole-House Dehumidifier for Simple Control
Best for: Mid-size homes wanting simple controls
Pros
- 80 pints per day
- Top or front control panel
- Leveling feet
- Once-a-year filter care
Cons
- No Wi-Fi
- Accessories not bundled
The AprilAire E080 Pro 80-Pint Whole-House Dehumidifier is the standard 80-pint model without Wi-Fi or a bundle. It covers up to 4,400 square feet and helps prevent damp carpets, mold, mildew, odors, termites and wood rot in basements and sealed crawl spaces. It is ENERGY STAR Most Efficient certified and has corrosion-resistant aluminum coils.
The control panel can mount on the top or front, it has leveling feet and an interactive display, and the filter needs cleaning or replacing about once a year. Specs list 612 watts, 185 cfm and 63 pounds. It suits a mid-size home where someone will set the humidity once and leave it alone.
How to Choose the Right AprilAire Dehumidifier
Match pints to your space. 70 pints suits crawl spaces and smaller homes, 80 pints suits up to 4,400 square feet, and 100 pints suits up to 5,500. Very damp spaces may need to size up.
Decide on Wi-Fi. The W models (E070W, E080W, E100W) let you monitor and adjust from your phone. The Pro models are set at the unit.
Check drainage. All models drain through a hose. If you have no floor drain nearby, the E080W includes a condensate pump; for other models you would need to arrange one.
Know what a Pro bundle adds. The E070 and E100 Pro bundles include a drain hose, a second filter and risers. They do not add Wi-Fi.
Whole-house or portable. If you just need one damp room, a smaller portable unit may be enough. Our guide to an ENERGY STAR portable dehumidifier covers that style.
FAQ
What does pints per day mean?
It is how much water the dehumidifier can remove from the air in 24 hours under standard test conditions. A higher number handles bigger or damper spaces.
Do AprilAire dehumidifiers need a water bucket?
No. The listings say there is no water tray to empty; you drain through a hose to a floor drain, or use a pump like the one included with the E080W.
What is the difference between the E080 Pro and E080W?
Both are 80 pints for up to 4,400 square feet. The E080W adds Wi-Fi and comes with a condensate pump, hanging kit and MERV 11 filter.
How long is the AprilAire warranty?
The E070W and E100W list 6 years. The E070 and E100 Pro bundles list 5 years. The E080 listings do not specify.
Can I install an AprilAire dehumidifier myself?
The listings describe ducting and hanging options but do not say whether professional installation is needed. Many owners hire an HVAC installer for ducted setups.
