AprilAire E080 Whole-Home Dehumidifier review

The AprilAire E080 is a stationary, whole-home dehumidifier for a homeowner planning a permanent drain and either ductwork or a dedicated below-grade air path. Its headline “80 pints per day” rating is tied to 80°F and 60% relative humidity; the current ENERGY STAR record uses the separate Appendix X1 test and lists 65 pints per day. It is not a wheeled room appliance with a tank to empty.

This assessment uses AprilAire’s exact E080 product page, its whole-house directory and FAQ, the exact ENERGY STAR E080 record, and AprilAire installation-and-owner manual 10020792B (02.24), hosted by a distribution partner. That manual names E080/E100, not E080W.

AprilAire links this clean, isolated cabinet image from the exact E080 product page. The image appears to be a studio-style rendering, but the manufacturer does not identify it as a photograph or render. It shows an inlet collar and the cabinet only; it does not prove how a particular home should be ducted.

Read the two capacity figures before comparing it

AprilAire calls this an 80-pint-per-day model and its E080/E100 manual specifies 80 pints at 80°F, 60% RH, and zero external static pressure, with 185 CFM airflow. ENERGY STAR’s current E080 record lists 65 pints per day under Appendix X1, an integrated energy factor of 2.35 L/kWh, annual energy use of 632 kWh, and a case volume of 3.3 cubic feet. These numbers are not a simple correction from 80 to 65: they are results under different capacity procedures. The E080’s name and manufacturer headline use 80; use the 65-pint Appendix X1 figure when you specifically need that standardized comparison. Neither test result predicts how much water a particular basement will produce each day.

The EPA record identifies E080 as a U.S. whole-home model, ENERGY STAR certified and Most Efficient, but not connected-capable. AprilAire describes an onboard digital control that can sit on top or at the inlet side; the exact E080 page does not establish Wi-Fi or app control. AprilAire lists a distinct E080W Wi-Fi model, whose capability must not be transferred to E080.

Make a drain and installation plan first

The E080 has no collection bucket to carry and empty. AprilAire sells it through its Healthy Air Professional network and includes 10-inch inlet and outlet collars, a backdraft damper, leveling feet, a barbed drain fitting, an eight-foot power cord, and a washable MERV 8 filter. For the simplest water route, the manual describes a continuously sloped drain line to a floor drain or a suitable exterior discharge. The drain must keep falling; a lift or a sag in soft tubing can stop gravity flow. The manuals also describe installing an external condensate pump as a separate device. That is not a built-in pump, is not in the listed box contents, and does not give the E080 a model-published vertical pump limit. A request for an integral pump and verified uphill lift should therefore rule it out.

Installation is a larger decision than plugging in a portable unit. AprilAire routes buyers through its professional network. For ducted distribution, the installer must account for the manual’s 0.4-inch-water-column maximum external static pressure. The unit can also serve below-grade spaces; “up to 4,400 square feet” is a manufacturer application claim, not a sizing answer for every house. Ask how air will enter and leave, where condensate will go, and how the layout will be checked.

Size, temperature and maintenance are part of ownership

The manufacturer lists a 15-inch-high, 14-inch-wide, 26-inch-deep cabinet. The E080 manual gives a 63-pound unit weight and 115-volt, 4.8-amp operating current. Leave service room to pull the filter and reach the drain; it is not a compact object to move room to room. The E080 manual specifies dehumidification inlet conditions from 50°F to 104°F and a 40°F minimum dew point. AprilAire explains that its units remove airborne moisture, not liquid condensation on cold windows or other surfaces. If the space routinely falls below its stated conditions, measure the actual temperature and humidity and talk through the application rather than treating the capacity label as a cold-weather guarantee.

Maintenance is modest but not zero. The manual says to check and clean the washable filter and drain every six months. Reinstall the drain insert before operation; the manual warns that running without it can cause condensate leaks. Filter care means rinsing and refitting it in the marked airflow direction. Unlike a bucket portable, there are no tank-emptying rounds, but the drain, filter and service access still need attention.

Who should choose the E080?

It makes sense when you want a fixed whole-home or below-grade installation, have a downward drain route, and can plan placement and ducting. Its 80-pint rating is tied to 80°F/60% RH; the separate 65-pint Appendix X1 figure matters when comparing current standardized labels. ENERGY STAR certification and 2.35 IEF are comparison facts, not a promised utility bill.

It is a poor fit if you need a built-in lift pump, a removable bucket, easy relocation, or confirmed app control. A portable model such as the Midea MAD50PS1QWT has a very different water-handling plan: its manual documents a fitted bucket and an integrated pump, while the E080 is gravity-drain-first and has no bucket. Do not choose between them by pint count alone. Compare where air must be moved, where water can drain, and whether your home needs a permanent system or a single-room appliance. For a larger whole-home requirement, AprilAire’s E100 and E130 listings are separate rated models—not automatic substitutes based only on house area. Confirm sizing, duct layout, drain connection and service access for the exact model before purchase.
