Quick Verdict
The AprilAire E080 80-Pint Whole-House Dehumidifier is the stronger all-round pick, ahead by 0.8 points. The one machine here whose ENERGY STAR Most Efficient badge survives the database.
The AprilAire E070 70-Pint Crawl Space / Whole-House Dehumidifier and AprilAire E080 80-Pint Whole-House Dehumidifier are both closely matched dehumidifier models, and the AprilAire E070 70-Pint Crawl Space / Whole-House Dehumidifier is $66 cheaper than the AprilAire E080 80-Pint Whole-House Dehumidifier ($1,441 vs $1,507). On Capacity-Claim Honesty, the AprilAire E080 80-Pint Whole-House Dehumidifier leads (9.5 vs 6.0/10) — this category's trap dimension. Since the DOE changed the test condition from 80°F/60% RH to 65°F/60% RH in 2019, the same machine that was a '70 pint' is now a '50 pint' — and manufacturers freely mix the two scales, plus a third 'saturation' figure taken at 95°F/90% RH. A high score means the pint number on the box matches the DOE Appendix X1 figure the manufacturer filed with ENERGY STAR. A low score means the marketing number is measured somewhere the buyer's house never is.. On Running Cost, the AprilAire E080 80-Pint Whole-House Dehumidifier leads (6.5 vs 4.5/10) — the kWh/yr on the ENERGY STAR certification and what it costs at the meter. On a machine that runs most of the year this dominates total ownership cost — often a third of the purchase price annually. On Value for Money, the AprilAire E080 80-Pint Whole-House Dehumidifier leads (6.0 vs 5.0/10) — purchase price plus multi-year electricity against verified pints removed and how long the warranty protects the compressor. Overall, the AprilAire E080 80-Pint Whole-House Dehumidifier scores 7.5/10 across our 8 scoring categories versus 6.7/10 for the AprilAire E070 70-Pint Crawl Space / Whole-House Dehumidifier. Below, we break down the full spec sheet, category-by-category scores, and exactly who should buy which one.
Side-by-Side Comparison
| Spec | AprilAire E070 70-Pint Crawl Space / Whole-House Dehumidifier | AprilAire E080 80-Pint Whole-House Dehumidifier |
|---|---|---|
| Price | $1441.00 | $1507.00 |
| Release Year | 2019 | 2021 |
| Rated Capacity (and Which Standard) | 70 pints/day at 80°F/60% RH, and 53 pints/day at 73°F/60% RH — AprilAire publishes both. The headline 70 is on the AHAM/pre-2019 condition, so this is NOT comparable to a modern 50-pint portable's DOE rating, and it is not 40% more machine than one either | 80 pints/day at 80°F/60% RH, 65 pints/day at 73°F/60% RH (AprilAire publishes both). The 73°F figure is the DOE Appendix X1 condition for whole-home units and matches AprilAire's ENERGY STAR filing exactly |
| ENERGY STAR / DOE Verified Capacity ( pints/day) | None — the E070 does not appear in the ENERGY STAR Certified Dehumidifiers database. Only the E080, E100 and E130 are certified. For reference, ENERGY STAR rates the E080 at 65.00 pints/day under Appendix X1 against AprilAire's own 80-pint headline, and whole-home units are tested at 73°F/60% RH rather than the 65°F/60% RH used for portables — a third rating point in the same category | 65.00 pints/day per Appendix X1, Integrated Energy Factor 2.35 L/kWh, 632 kWh/yr, R32 with a 9.7 oz charge, case volume 3.3 ft³ — AprilAire's own ENERGY STAR filing, certified 23 September 2025 and flagged as meeting Most Efficient criteria. Note that whole-home units are tested at 73°F/60% RH while portables are tested at 65°F/60% RH, so a 65-pint whole-home figure is still not directly comparable to a 50-pint portable figure |
| Technology & Refrigerant | Compressor (refrigerant), R32, 5.4 amps at 120V, 200 CFM at 0.0 in external static pressure, energy factor 2.1 L/kWh at 80°F/60% RH and 1.8 L/kWh at 73°F/60% RH | Compressor (refrigerant), R32, 4.8 amps at 120V, 185 CFM at 0.0 in external static pressure, energy factor quoted by AprilAire as 2.8 L/kWh at 80°F/60% RH |
| Low-Temperature Operation & Defrost | 50°F to 104°F for dehumidification (40°F to 140°F in ventilation-only mode). That 50°F floor is better than a 41°F-rated portable in practice but worse than the AlorAir's 33.8°F — for a genuinely cold crawlspace the AlorAir or a desiccant is the safer choice | 50°F to 104°F for dehumidification. Same floor as the E070 — good for a conditioned basement, not for a 40°F crawlspace |
| Claimed Coverage | Sources conflict by a factor of two: AprilAire's own shop page says "whole houses up to 2,200 sq. ft.", the Amazon listing says "up to 2,800 sq. ft", and amgair.com's spec table for the same model says 4,400 sq. ft | 4,400 sq ft (AprilAire dealer spec sheet). Note the E070 below it is variously published at 2,200, 2,800 and 4,400 sq ft, so the coverage figures for the two models overlap in the sources |
| Tank Capacity & Refill Interval | None — there is no water tray. This is a plumbed appliance | None — plumbed appliance, no water tray |
| Continuous Drainage (Hose, Gravity, Pump Lift) | Gravity drain only, with a barbed fitting and 10 ft of tubing included. There is no pump, so the unit must be sited above a drain or paired with a separate condensate pump. That is the practical difference between this and the pump-equipped AlorAir | Gravity drain, no built-in pump. Duct kits, a remote controller and a hang kit are all separate accessories, not in the box |
| ENERGY STAR Status | NOT certified. amgair.com markets this model as "Most Efficient | Energy Star Rated"; the E070 is absent from both the ENERGY STAR Certified Dehumidifiers list and the ENERGY STAR Most Efficient list. The E080, E100 and E130 above it are certified and are Most Efficient | Yes, certified, IEF 2.35 L/kWh, 632 kWh/yr, and it is on the ENERGY STAR Most Efficient list — the only product in this comparison for which that claim is verifiable |
| Annual Running Cost | Not published as an annual figure, because there is no ENERGY STAR entry. At 5.4 A / 120V (about 648W) and crawlspace duty cycles, budget for something in the region of the E080's certified 632 kWh/yr — roughly $107/yr at $0.17/kWh | About $107/yr (632 kWh x $0.17/kWh) on the DOE usage assumption. Higher in absolute terms than a portable because it is a bigger machine — but per pint removed it is the most efficient unit here at IEF 2.35 against 2.01 for the mainstream portables |
| Noise | 53 dBA ducted (AprilAire) | Not published by AprilAire for the E080. The E070 on the same chassis family is quoted at 53 dBA ducted |
| Warranty (incl. Sealed System) | 5 years on parts and the sealed system, per AprilAire and its dealers. This is the single strongest warranty position in the comparison alongside the AlorAir, and it is the reason the price is what it is | 5 years on parts and the sealed system |
| Recall History | No CPSC recall found for AprilAire dehumidifiers | No CPSC recall found for AprilAire dehumidifiers |
| Warranty | 60 months | 60 months |
| Colors | White | White |
Category Scores
Capacity-Claim Honesty
The AprilAire E080 80-Pint Whole-House Dehumidifier leads clearly here, 9.5 against 6.0 — a 3.5-point margin on this category's trap dimension. Since the DOE changed the test condition from 80°F/60% RH to 65°F/60% RH in 2019, the same machine that was a '70 pint' is now a '50 pint' — and manufacturers freely mix the two scales, plus a third 'saturation' figure taken at 95°F/90% RH. A high score means the pint number on the box matches the DOE Appendix X1 figure the manufacturer filed with ENERGY STAR. A low score means the marketing number is measured somewhere the buyer's house never is.. If that is what you are buying for, the AprilAire E070 70-Pint Crawl Space / Whole-House Dehumidifier does not close the gap elsewhere.
Moisture Removal
The AprilAire E080 80-Pint Whole-House Dehumidifier leads clearly here, 9.0 against 8.5 — a 0.5-point margin on actual water pulled out of the air per day at a condition a home experiences, judged against the DOE-verified figure rather than the coverage claim on the box. If that is what you are buying for, the AprilAire E070 70-Pint Crawl Space / Whole-House Dehumidifier does not close the gap elsewhere.
Cold-Room Performance
The AprilAire E070 70-Pint Crawl Space / Whole-House Dehumidifier and AprilAire E080 80-Pint Whole-House Dehumidifier are level here, at 6.5/10 each. what happens in a 50-55°F basement, garage or crawlspace. Compressor coils frost below roughly 65°F and auto-defrost buys back the coil at the cost of runtime; desiccant rotors and hot-gas-defrost units do not care. The single most common mis-buy in the category is not what separates these two — look to the categories where the scores diverge.
Drainage & Tank Practicality
The AprilAire E070 70-Pint Crawl Space / Whole-House Dehumidifier and AprilAire E080 80-Pint Whole-House Dehumidifier are level here, at 7.0/10 each. tank volume measured against daily output, whether a hose is in the box, whether gravity drainage needs the unit propped up, and whether there is a real pump and how high it lifts is not what separates these two — look to the categories where the scores diverge.
Running Cost
The AprilAire E080 80-Pint Whole-House Dehumidifier leads clearly here, 6.5 against 4.5 — a 2.0-point margin on the kWh/yr on the ENERGY STAR certification and what it costs at the meter. On a machine that runs most of the year this dominates total ownership cost — often a third of the purchase price annually. If that is what you are buying for, the AprilAire E070 70-Pint Crawl Space / Whole-House Dehumidifier does not close the gap elsewhere.
Quietness
The AprilAire E070 70-Pint Crawl Space / Whole-House Dehumidifier leads clearly here, 6.5 against 6.0 — a 0.5-point margin on measured dB where published, weighted by where the machine actually lives — a 58 dBA crawlspace unit under a floor is fine, a 54 dB cube next to a desk is not. If that is what you are buying for, the AprilAire E080 80-Pint Whole-House Dehumidifier does not close the gap elsewhere.
Build & Warranty
The AprilAire E070 70-Pint Crawl Space / Whole-House Dehumidifier and AprilAire E080 80-Pint Whole-House Dehumidifier are level here, at 9.5/10 each. coil and cabinet construction, filter grade, and above all the warranty on the sealed system — the compressor is the part that fails and the part most portables cover for only twelve months is not what separates these two — look to the categories where the scores diverge.
Value for Money
The AprilAire E080 80-Pint Whole-House Dehumidifier leads clearly here, 6.0 against 5.0 — a 1.0-point margin on purchase price plus multi-year electricity against verified pints removed and how long the warranty protects the compressor. If that is what you are buying for, the AprilAire E070 70-Pint Crawl Space / Whole-House Dehumidifier does not close the gap elsewhere.

Pros & Cons
AprilAire E070 70-Pint Crawl Space / Whole-House Dehumidifier
Pros
- +5-year parts and sealed-system warranty on a US-built unit, against 1 year from every portable here
- +Publishes capacity at two conditions (70 ppd at 80°F, 53 ppd at 73°F) instead of only the flattering one
- +MERV 8 washable filter means it is doing air cleaning as well as drying, unlike the mesh screens on the portables
- +No tray to empty and corrosion-resistant coils designed for years of crawlspace duty
Cons
- −amgair.com sells it as "Most Efficient | Energy Star Rated" — the E070 is in neither ENERGY STAR list; the E080 above it is
- −"70 pint" is an 80°F/60% RH figure. Cross-shopped against a 50-pint portable it looks like 40% more machine; measured at the same conditions it is not
- −Coverage is published as 2,200 (AprilAire), 2,800 (Amazon) and 4,400 (dealer) sq ft for the same unit
- −Gravity drain only — no pump, so a crawlspace without a low drain needs a condensate pump on top of the $1,441
- −50°F dehumidification floor is not low enough for the coldest crawlspaces, where the AlorAir's 33.8°F or a desiccant wins
AprilAire E080 80-Pint Whole-House Dehumidifier
Pros
- +The only product in this comparison whose ENERGY STAR Most Efficient claim is actually in the ENERGY STAR database
- +IEF 2.35 L/kWh against 2.01 for the mainstream 50-pint portables — meaningfully cheaper per pint removed
- +AprilAire's published 65 ppd at 73°F matches its DOE Appendix X1 filing to two decimal places; nothing is being hidden
- +5-year parts and sealed-system warranty, MERV 8 filtration, US-built
Cons
- −$1,507 before the duct kit, hang kit and remote controller, none of which are in the box
- −Gravity drain only — no pump, same as the E070
- −50°F dehumidification floor: for a genuinely cold crawlspace the AlorAir HDi90 or a desiccant is the right machine
- −AprilAire publishes no dB figure for the E080 at all
- −Sold through multiple concurrent Amazon listings (bundle, pro, DIY kit) at different prices for the same appliance
