The catch
AprilAire E070 Pro
For a clearly larger load, the lower matched-condition removal rating may not be enough.
Side by side
AprilAire E070 vs E100: E100 needs a larger-capacity installation, E070 is easier to place
Quick verdict
E070 fits when its 70-pint rating meets the calculated load and the lower, lighter cabinet or eight-inch connections are important. E100 fits when the design needs its 100-pint capacity and can support the larger cabinet and duct route. E100 adds 30 rated pints but needs ten-inch collars instead of eight-inch ones. Minimum inlet conditions are the same for both, so the larger model is no remedy for an installation that runs too cold.
Before you buy
Why, and what it costs you
A big jump in capacity can mean a bigger installation job
At the stated matched conditions, E100’s 100-pint rating is about 43% above E070’s 70. It also changes from eight-inch to ten-inch collars and puts 8 lb on a taller body. In a crawlspace that is hard to reach, those changes affect delivery, duct connections and later service. The extra rating may go unused if E070 already meets the calculated load. If it does not, pick the larger capacity and do the necessary installation work, and do not choke it back into an unverified old duct path.
Where this comes from
(100 - 70) / 70 comes to about 43%, and that compares capacity ratings only. Changes in collar, height and weight are set against replacement access.
The catch
AprilAire E100
The body stands 2.5 inches taller and weighs 8 lb more. Replacement can get complicated by larger connections and service space.
AprilAire E070 Pro
- Why pick it
- The verified load fits within 70 pints, and the access route favors a 12.5-inch-high, 56 lb unit.
- It is worth preserving an appropriate eight-inch installation.
- The catch
- For a clearly larger load, the lower matched-condition removal rating may not be enough.
AprilAire E100
- Why pick it
- Your calculated load calls for the 100-pint class, and the duct design satisfies its pressure requirements.
- You are able to supply ten-inch connections along with enough filter and drain access.
- The catch
- The body stands 2.5 inches taller and weighs 8 lb more. Replacement can get complicated by larger connections and service space.

What this page compares
AprilAire E070 vs E100 for a constrained crawlspace or a larger ducted job, weighed on access, existing ducts and why a bigger rating cannot fix cold inlet air.
Someone sizing a permanent AprilAire installation may be tempted to leap from E070 to E100 for headroom. What is worth asking is whether that headroom suits the building and the installation.

Differences you will notice
A big jump in capacity can mean a bigger installation job
At the stated matched conditions, E100’s 100-pint rating is about 43% above E070’s 70. It also changes from eight-inch to ten-inch collars and puts 8 lb on a taller body. In a crawlspace that is hard to reach, those changes affect delivery, duct connections and later service. The extra rating may go unused if E070 already meets the calculated load. If it does not, pick the larger capacity and do the necessary installation work, and do not choke it back into an unverified old duct path.
How we worked this out
(100 - 70) / 70 comes to about 43%, and that compares capacity ratings only. Changes in collar, height and weight are set against replacement access.
In winter, the reason for buying the larger label can vanish
For dehumidification, a 50 F minimum inlet temperature and a 40 F minimum dew point are set in both manuals. So a cool crawlspace can pose a placement or operating-envelope problem that E100’s bigger warm-condition rating does not solve. Check the seasonal conditions where air enters the unit. Drainage calls for the same caution. With no onboard pump on either, a higher disposal point still needs a separate solution. Capacity, temperature and water routing all have to fit at the same time.
How we worked this out
Inlet limits both units share and drainage without a pump, set against seasonal cold and an elevated disposal point. Nothing is claimed about performance outside the published conditions.
The service path can outweigh the cabinet difference
On one side, E100 needs 15 inches for filter withdrawal. You can find room for the 14-inch-wide cabinet and still block the movement cleaning requires. E070’s smaller body does not excuse it from its own access instructions, either. Before deciding that either unit fits, sketch where the filter comes out and where someone can reach the drain. That is especially important when the appliance sits behind storage that goes back in place after installation.
How we worked this out
The documented E100 filter withdrawal, set against how storage is really used and a permanent placement. E070 clearance is neither guessed at nor declared smaller.

Spec by spec
Where they really differ
| Spec | AprilAire E070 Pro | AprilAire E100 | In practice |
|---|---|---|---|
| Matched capacity | 70 pints at 80 F and 60% RH | 100 pints at 80 F and 60% RH | A household drying-time ratio cannot be derived from the 30-pint difference. |
| Body height and weight | 12.5 inches, 56 lb | 15 inches, 64 lb | More margin for transport and placement is left by E070. |
| Duct connection | Eight-inch collars | Ten-inch collars | Reuse of a small duct route calls for a check, and an adapter alone won't do. |
| Cold inlet boundary | 50 F minimum and 40 F minimum dew point | Same limits | More capacity leaves the shared lower boundary in place. |
Trade-offs
What each pick costs you
With AprilAire E070 Pro
- Confirm whether the existing ducts are compatible. Eight-inch collars on their own do not make a whole-system design.
With AprilAire E100
- The installed total has to include the drain hose, any separate pump and optional controls.
Change of plan
When the answer changes
70-pint sizing is enough, and access is the tougher problem
Go with AprilAire E070 Pro. The smaller, lighter body is E070's.
The larger unit is needed for the verified moisture load, and its installation works
Go with AprilAire E100. The higher capacity comes from E100.
Decision guide
Before you buy
You want enough capacity for the hard season, but without overcomplicating a crawlspace installation that is already awkward.
What this page can’t tell you
- Nothing about a home's size or its occupants is used to infer an exact capacity threshold. A ratio between ratings is not a ratio of speed or efficiency.
