An Aprilaire dehumidifier is not a portable unit you carry from room to room. The E-series are heavy, commercial-grade machines built to sit in a basement or crawl space, or to tie into your forced-air ductwork and dry the whole house. The number in the name is the pints per day each one removes at the industry test condition of 80F and 60% relative humidity: 70, 80, 100 or 130.
Three of the four are on ENERGY STAR's current certified list, and all three are marked as meeting ENERGY STAR's Most Efficient criteria. ENERGY STAR measures whole-home units at a cooler test point, so its pints figures are lower than the name on the box. That is normal, and it is the fairest way to compare them with other brands.
| Model | Rated pints/day (80F, 60% RH) | ENERGY STAR pints/day | Coverage (maker FAQ / Amazon) | Airflow | Weight |
|---|---|---|---|---|---|
| E070 | 70 | Not listed | 2,800 sq ft crawl space / 2,200 sq ft | 200 CFM | 56 lb |
| E080 | 80 | 65 (IEF 2.35) | 3,800 / 4,400 sq ft | 185 CFM | 63 lb |
| E100 | 100 | 85 (IEF 2.35) | 5,200 / 5,500 sq ft | 280 CFM | 64 lb |
| E130 | 130 | 105 (IEF 2.35) | 7,200 / 7,200 sq ft | 310 CFM | 98 lb |

Aprilaire E100
Aprilaire E100 Whole-Home Dehumidifier
Best for: basements and whole homes up to about 5,000 sq ft.
The Aprilaire E100 is the model most installers reach for, and the one most people searching for an Aprilaire E100 dehumidifier end up with. It removes 100 pints a day at 80F and 60% RH. Aprilaire's spec sheet also gives 85 pints a day at 73F and 60% RH, which matches its ENERGY STAR record: 85 pints a day, an integrated energy factor of 2.35 L/kWh and an estimated 821 kWh a year (about $149 at the U.S. average electricity price we use on this site).
Aprilaire's FAQ rates it for homes up to 5,200 sq ft, and the Amazon listing says 5,500. Airflow is 280 CFM with no duct attached, 245 CFM at 0.2 in. of static pressure and 210 CFM at 0.4 in., per the spec sheet. That is the number your installer needs when sizing the duct run. If you want app control, the E100W version adds Wi-Fi.
Heads up: Sold on Amazon as well as through HVAC contractors. Ducted installs should be done by a pro.
| Model number | E100 |
|---|---|
| Type | Whole-house (ducted or ventilating) |
| Capacity (AHAM test, 80F, 60% RH) | 100 pints/day |
| Coverage | Up to 5,200 sq ft (maker FAQ); Amazon listing says up to 5,500 sq ft |
| Built-in pump | No |
| Wi-Fi / app | No |
| ENERGY STAR | Yes |
| Noise | Not published |
| Airflow | 280 CFM (Amazon listing) |
| Weight | 64 lb |
| Sizing note | Aprilaire sizes by climate region and how airtight the home is; ask the installer to run its Dehumidifier Selection Assistant |
| Capacity at 73F, 60% RH | 85 pints/day (Aprilaire spec sheet) |
| ENERGY STAR test data | 85.0 pints/day, IEF 2.35 L/kWh, about 821 kWh/yr; meets ENERGY STAR Most Efficient (record for E100) |
| Price tier | Pro (about $900 and up) |
Pros
- Enough capacity for most basements and whole homes
- ENERGY STAR Most Efficient
- Can be ducted or free-standing
- Wi-Fi version available (E100W)
Cons
- Heavy (64 lb) and loud enough that most people duct it or put it in a utility area
- Ducted installs need an HVAC pro
- Pro price tier

Aprilaire E080
Aprilaire E080 Whole-Home Dehumidifier
Best for: mid-size homes and finished basements.
The Aprilaire E080 is the step down: 80 pints a day at 80F, and 65 pints a day on the ENERGY STAR test at the same 2.35 L/kWh as the E100. Aprilaire rates it up to 3,800 sq ft (the Amazon listing says 4,400). Its airflow is lower at 185 CFM, which suits a smaller duct system or a single open basement.
Heads up: Sold on Amazon as well as through HVAC contractors. Ducted installs should be done by a pro.
| Model number | E080 |
|---|---|
| Type | Whole-house (ducted or ventilating) |
| Capacity (AHAM test, 80F, 60% RH) | 80 pints/day |
| Coverage | Up to 3,800 sq ft (maker FAQ); Amazon listing says up to 4,400 sq ft |
| Built-in pump | No |
| Wi-Fi / app | No |
| ENERGY STAR | Yes |
| Noise | Not published |
| Airflow | 185 CFM (Amazon listing) |
| Weight | 63 lb |
| Sizing note | Aprilaire sizes by climate region and how airtight the home is; ask the installer to run its Dehumidifier Selection Assistant |
| ENERGY STAR test data | 65.0 pints/day, IEF 2.35 L/kWh, about 632 kWh/yr; meets ENERGY STAR Most Efficient (record for E080) |
| Price tier | Pro (about $900 and up) |
Pros
- Same efficiency as the E100
- Smaller and cheaper to run (about $115 a year at our rate)
Cons
- Less airflow for long duct runs
- Still a pro-tier purchase

Aprilaire E070
The Aprilaire E070 dehumidifier is the crawl space model. It is rated at 70 pints a day at 80F, sized by Aprilaire for crawl spaces up to 2,800 sq ft, and the Amazon listing gives 200 CFM. It is built low and compact to fit under a house, and the E070W version adds Wi-Fi and a pump bundle on Amazon. It is the one Aprilaire model we did not find on ENERGY STAR's certified list.
If your crawl space is encapsulated, a unit like this holds the space dry all year. If it is open to outside air, fix that first: no dehumidifier can keep up with a vented crawl space in humid weather.
Heads up: Sold on Amazon as well as through HVAC contractors. Ducted installs should be done by a pro.
| Model number | E070 |
|---|---|
| Type | Whole-house (ducted or ventilating) |
| Capacity (AHAM test, 80F, 60% RH) | 70 pints/day |
| Coverage | Up to 2,800 sq ft (crawl space use; maker FAQ); Amazon listing says up to 2,200 sq ft |
| Built-in pump | No |
| Wi-Fi / app | No |
| ENERGY STAR | Not stated |
| Noise | Not published |
| Airflow | 200 CFM (Amazon listing) |
| Weight | 56 lb |
| Sizing note | Aprilaire sizes by climate region and how airtight the home is; ask the installer to run its Dehumidifier Selection Assistant |
| Price tier | Pro (about $900 and up) |
Pros
- Low-profile for crawl spaces
- Wi-Fi version
- Amazon bundles with pump and hanging kit
Cons
- Not on ENERGY STAR's certified list
- Overkill for a small sealed crawl space

Aprilaire E130
Aprilaire E130 Whole-Home Dehumidifier
Best for: large homes over about 5,000 sq ft and humid climates.
The Aprilaire E130 is the largest: 130 pints a day at 80F (about 16 gallons), 105 pints a day on the ENERGY STAR test, 310 CFM and up to 7,200 sq ft. At 98 lb it is a two-person lift. It makes sense for very large homes, homes in hot and humid climates with tight construction, or light commercial spaces.
Heads up: Sold on Amazon as well as through HVAC contractors. Ducted installs should be done by a pro.
| Model number | E130 |
|---|---|
| Type | Whole-house (ducted or ventilating) |
| Capacity (AHAM test, 80F, 60% RH) | 130 pints/day |
| Coverage | Up to 7,200 sq ft (maker FAQ); Amazon listing says up to 7,200 sq ft |
| Built-in pump | No |
| Wi-Fi / app | No |
| ENERGY STAR | Yes |

| Sizing note | Aprilaire sizes by climate region and how airtight the home is; ask the installer to run its Dehumidifier Selection Assistant |
| ENERGY STAR test data | 105.0 pints/day, IEF 2.35 L/kWh, about 926 kWh/yr; meets ENERGY STAR Most Efficient (record for E130) |
| Price tier | Pro (about $900 and up) |
Pros
- Highest capacity
- ENERGY STAR Most Efficient
- Castor version (E130C) for floor use
Cons
- 98 lb
- Most homes do not need this much

Aprilaire 1850 vs 1830
Before the E-series, Aprilaire sold the 1800 series, and many homes still have one. The two most common are the Aprilaire 1850 and Aprilaire 1830. Both were rated at 80F and 60% RH:
| Aprilaire 1830 | Aprilaire 1850 | |
|---|---|---|
| Capacity | 70 pints/day | 95 pints/day |
| Airflow (0.0 in. w.c.) | 160 CFM | 265 CFM |
| Current draw | 6.3 A | 8 A |
| Positioned for | Smaller homes, condos, crawl spaces | Whole homes |
Sources: Aprilaire 1830 manual and 1850 specification sheet.
If your Aprilaire dehumidifier 1850 or 1830 has failed, the closest modern replacements by capacity are the E100 (for an 1850) and the E070 or E080 (for an 1830). Have the installer check the duct connections, because the E-series units have different dimensions and airflow.
Install cost
The unit is only part of the cost. Ducted Aprilaire installs involve a supply and return connection, a drain line, a wall control and sometimes a dedicated circuit. Published estimates vary widely:
| Source | What it covers | Estimate |
|---|---|---|
| Homewyse (May 2026) | Install a whole house dehumidifier, national average | $2,774 to $3,285 per unit |
| PickHVAC | Whole-house unit with installation, Midwest labor, moderate ductwork | $900 to $2,500, about $1,700 average |
Get two or three quotes from local HVAC contractors. A free-standing basement or crawl space setup (the unit on the floor or hung from joists, draining to a floor drain or pump) costs much less to install than a fully ducted one, and many owners do that part themselves. For a full breakdown, see our whole house dehumidifier cost guide.
Aprilaire vs Santa Fe
Santa Fe is Aprilaire's main rival for whole-home and crawl space units. On ENERGY STAR's records, Santa Fe's current Ultra V-series posts higher efficiency numbers than Aprilaire's E-series:
| Model | ENERGY STAR pints/day | IEF (L/kWh) | Est. kWh/yr |
|---|---|---|---|
| Aprilaire E080 | 65 | 2.35 | 632 |
| Aprilaire E100 | 85 | 2.35 | 821 |
| Aprilaire E130 | 105 | 2.35 | 926 |
| Santa Fe Ultra V100 | 85.62 | 2.45 | 419 |
| Santa Fe Ultra V125 | 102.69 | 2.63 | 565 |
| Santa Fe Ultra V155 | 127.51 | 3.26 | 842 |
Source: ENERGY STAR certified dehumidifier dataset, checked November 2026.
Aprilaire's advantages are wide availability (including Amazon), a broad installer network, and simple models. Santa Fe's are efficiency and options such as fresh-air ventilation on some Ultra models. See our Santa Fe dehumidifier review for the full lineup.
Pros and cons of Aprilaire
