Our Aprilaire E070 review covers performance, design, cleaning, pros and cons, and who should buy it. Plus top alternatives. Updated 2026. Updated for 2026.
A damp crawl space or basement rarely stays a small problem. Moisture spreads into musty odors, warped wood, and mold growth that reaches the rooms above. This aprilaire e070 review looks at a different kind of fix from the portable unit you wheel from room to room. The E070 is a compact whole home dehumidifier built to dry the air for the entire house.
Below, we walk through its capacity, drainage, controls, upkeep, and costs, plus the types of homes it suits and the cases where a simpler room unit makes more sense. The comparison table below sums up how this class of machine stacks up against portable options.
The Short Answer: Who the E070 Suits Best
The E070 makes sense if humidity is a whole home problem rather than a single damp room. It removes up to 70 pints of water per day, drains through a hose instead of a bucket, and can tie into your ductwork or run on its own in a sealed crawl space. Skip it if you rent, if only one bedroom feels clammy, or if you have no drain nearby and no budget for installation help. For owners of humid homes, it is a serious, permanent answer.
Aprilaire E070 Specs at a Glance
The figures below anchor this aprilaire e070 review, because sizing and drainage decide whether a unit like this works in your home at all.
- Capacity: up to 70 pints of moisture removed per day
- Coverage: check the manufacturer's square footage rating against your home and climate
- Size and weight: a compact cabinet, but a heavy one, so plan a two person lift
- Drainage: gravity drain hose or an added condensate pump, with no bucket to empty
- Controls: built in digital control, with an optional wall control for living space access
- Filter: washable air filter that you rinse rather than replace
- Warranty: confirm the current coverage term on the listing
Design and Build Quality
Most portable dehumidifiers are tall plastic boxes on casters. The E070 looks nothing like them. It is a low, rectangular cabinet shaped to slide through a crawl space access door. It is heavy enough to be a two person lift, but once placed it stays put for years, so the weight matters less than the footprint.
The cabinet feels like HVAC equipment rather than a small appliance. Duct collars let a contractor connect it to your home supply and return ducts, or it can draw and discharge air directly in the space where it sits. Corrosion resistant construction matters here, since the unit spends its life in the damp air it treats. There are no wheels and no water tank, because the design assumes a fixed spot with a drain line from day one.
Performance
Coverage and Sizing
Aprilaire publishes a coverage rating for the E070 in square feet. Treat that figure as a best case for a sealed, moderately humid home rather than a promise. A leaky house in a Gulf Coast summer loads a dehumidifier far more than a tight home in a mild climate, even at the same square footage. If your home is larger, poorly sealed, or sits over an open dirt crawl space, step up to a higher capacity class instead of asking this unit to run without rest.
Moisture Removal in Daily Use
The 70 pint daily rating describes how much water the unit can pull from the air under test conditions. In a real home, the practical effect is steady control rather than a fast dry out. You set a target humidity level, often around 50 percent, and the machine cycles to hold it as weather and indoor moisture change. Showers, cooking, and wet weather add load during the day, and a correctly sized unit absorbs those swings without the air ever feeling swampy by evening.
Noise Level
Because the E070 lives outside your living space, noise works differently than with a portable unit humming in the corner of a bedroom. Sound comes mainly through the ductwork or the floor above a crawl space install. In a basement or crawl space placement, most households notice little more than a faint hum during cycles. If the unit must sit in a utility closet beside a bedroom, ask your installer about ducted returns and vibration pads, since placement and duct layout shape what you hear more than the machine itself.
Energy Use
A whole home unit runs more hours than a portable, so efficiency per pint matters more than the draw in any single hour. Compare models by how much water each removes per kilowatt hour, a figure makers publish in their spec sheets, rather than by wattage alone. Holding a steady set point also saves energy compared with letting humidity climb and then forcing a long recovery cycle. Expect the E070 to add a visible but modest amount to a summer power bill in a humid climate, in exchange for drying the entire house at once.
Key Features That Matter
Continuous drainage. There is no bucket to check, carry, or overflow. Water leaves through a drain hose by gravity, or through a condensate pump where the drain sits above the unit. This single feature is what makes unattended operation in a crawl space realistic.
Flexible installation. The E070 can be ducted into your HVAC system so it treats air across the whole home, or it can stand alone and condition the space it sits in. That choice lets the same machine serve a sealed crawl space now and a ducted whole home layout later.
Automatic control. The built in digital control reads humidity and runs the unit only when the air needs drying. An optional wall mounted control lets you adjust the set point from a hallway instead of crawling to the machine, and automatic defrost keeps the coil working when the space runs cool.
Ease of Use, Cleaning, and Maintenance
Day to day, there is almost nothing to do. You choose a humidity set point once, and the control handles the rest. The one routine task is the washable filter. When the control flags it, or about once a year in a typical install, you slide the filter out, rinse it with water, let it dry fully, and slide it back in. Skipping this step chokes airflow and quietly raises running costs.
Once a year, also confirm the drain line is clear and still slopes toward the drain, since a sagging hose can hold water and grow slime. Keep access space around the cabinet so a service tech can reach the panels easily. If the unit runs constantly yet humidity stays high, that pattern points to a sizing problem, a blocked filter, or a sealing issue worth fixing at the source.
Aprilaire E070 Pros and Cons
Pros
- Dries a whole home or a sealed crawl space from one fixed unit
- No bucket to empty, thanks to continuous drainage
- Compact cabinet fits through most crawl space access doors
- Washable filter avoids recurring filter costs
- Quiet in practice, because it sits outside living areas
Cons
- High purchase price compared with portable units
- Installation often needs a contractor, adding to total cost
- No help for a renter or for one small damp room
- Needs a drain or a condensate pump within reach
Who Should Buy the Aprilaire E070, and Who Should Skip It
Buy it if you own a home of moderate size with a sealed crawl space or a basement that stays damp through the season, and you are tired of emptying portable units that never quite keep up. It also suits homes where musty odors trace back to moisture under the house, since drying that space improves the air above it. Encapsulation projects are a natural fit, because drain and duct planning happen while access is easy.
Skip it if your dampness is limited to one bathroom or laundry room, if you move often, or if your home is far larger than the rated coverage and needs a bigger class of machine. Also skip it if there is no realistic drain route, because solving drainage after purchase is the most common source of regret with this type of unit.
Aprilaire E070 vs Alternatives: Types Compared
The real choice is not between brands. It is between three types of machine. A ducted whole home unit like the E070 treats every room from one hidden location and never needs emptying, but it costs the most and suits owners who plan to stay put. A portable room unit costs far less and rolls where you need it, yet it dries one space at a time and fills its bucket in humid weather. Our midea cube 50 pint review shows what the stronger portables can do in a large basement or open plan area.
At the smallest end, compact thermoelectric and mini units serve closets, small bedrooms, and RV spaces where moisture loads are light. They are cheap and silent, but they remove a fraction of the water a refrigerant unit handles. The pro breeze mini dehumidifier review covers that class well. If your problem is a whole humid house, neither portable type substitutes for the E070. If your problem is one small space, the E070 is far more machine than you need.
Where to Buy and What to Budget
Expect to pay about $1,700 to $1,900 for the unit alone, with the total climbing once you add duct collars, a wall control, a condensate pump, or contractor labor. Professional installation can add several hundred dollars. Seasonal sales events can trim the unit price, so compare the full installed cost, not just the box price, before you order.
FAQs
Is the Aprilaire E070 worth it?
It is worth it when humidity affects the whole home and you plan to stay long enough to spread the installed cost over many seasons. One fixed unit replaces the purchase, noise, and bucket duty of several portables. It is not worth it for a single damp room, where a portable solves the problem for a small share of the price.
What are common Aprilaire E070 problems?
Most complaints trace back to installation rather than the machine. A drain line without enough slope can back water up, an undersized unit in a larger home runs without pause, and a clogged filter raises humidity readings that look like a failure. Error codes on the control usually point to sensor or drain issues, and your installer or the manual should be the first stop before assuming a major fault.
How long does the Aprilaire E070 last?
Whole home dehumidifiers of this class commonly serve for many years, and the manufacturer warranty gives a floor for your expectations. Lifespan depends heavily on run hours and on the air it breathes. A clean filter, a clear drain, and a sealed space all reduce strain. Units in raw dirt crawl spaces with heavy dust tend to age faster than units in clean basements.
What is a cheaper alternative to the Aprilaire E070?
A portable refrigerant dehumidifier is the main cheaper route, costing a few hundred dollars instead of over a thousand. The trade is scope and effort: you dry one area, move the unit as needed, and empty a bucket or route a hose to a drain. For a basement only problem, that compromise often makes financial sense.
How do you clean the Aprilaire E070?
Cleaning centers on the washable filter. Power the unit down, slide the filter from its slot, rinse it under water until it runs clear, and let it dry completely before reinstalling, since a damp filter invites odor. Wipe dust from the cabinet exterior and check that the intake and discharge openings stay clear of stored items and insulation.
Final Thoughts
The E070 is not an impulse buy. It is a permanent moisture fix for owners whose crawl space or basement keeps the whole house humid, and who value quiet, unattended drying over a low sticker price. Weigh your square footage, your drain route, and your installation budget against the product table above. If those three line up, the aprilaire e070 review verdict is simple: this is one of the most complete answers in its class.
