Main trade-off
Santa Fe Ultra70
Lower capacity and airflow may not meet the design. The drain-trap arrangement can erase its bare-height advantage.
Head-to-head
Santa Fe Ultra70 vs AprilAire E100: Ultra70 keeps eight-inch connections, E100 adds capacity and fan headroom
The short answer
Choose E100 when the calculated load and duct resistance need its higher capacity and fan performance. At 0.2 inches of static pressure, E100 lists 245 CFM and Ultra70 lists 140. Choose Ultra70 when its 70-pint sizing is sufficient and an approved eight-inch system or narrower body matters more. Its low body still needs the current manual’s raised drain-trap arrangement. Both require complete installation checks.
Before you choose
The reasoning and the trade-offs
The existing ducts can favor the smaller model or justify the larger one
Ultra70’s eight-inch collars can suit an existing appropriately designed route, while E100 needs ten-inch connections. Yet at a matched 0.2 inches water column, E100’s fan curve lists 245 CFM versus 140. Keeping old ducts purely to avoid work can therefore be the wrong saving if the load or resistance exceeds the smaller unit’s design. An installer should check the whole path. These airflow values do not establish how many pints either will remove through your installation.
What this is based on
Matched fan-pressure point and differing collar sizes crossed with replacement infrastructure. Airflow remains distinct from moisture-removal rate.
Main trade-off
AprilAire E100
A wider, taller and 9 lb heavier body with larger collars can make replacement more involved.
Santa Fe Ultra70
- Choose it for
- The calculated load fits Ultra70 and an eight-inch duct design is worth preserving.
- Its narrower body fits with the drain trap, filter access and A2L installation requirements.
- Main trade-off
- Lower capacity and airflow may not meet the design. The drain-trap arrangement can erase its bare-height advantage.
AprilAire E100
- Choose it for
- The installation needs the higher matched-condition capacity and stronger fan curve.
- Ten-inch collars, the larger body and washable-filter service fit the site.
- Main trade-off
- A wider, taller and 9 lb heavier body with larger collars can make replacement more involved.
About this comparison
Santa Fe Ultra70 vs AprilAire E100 for an existing ducted home. Compare pressure-dependent airflow, drain-trap height and the routine of filter replacement.
A buyer planning whole-home dehumidification may weigh a low-profile 70-pint installation against a 100-pint system with a stronger fan curve. The same house can produce this choice when access and ducts constrain sizing.
Winner by situation
Start with what you need it to do
Verified 70-pint sizing and suitable eight-inch infrastructure
Ultra70 avoids a collar-size change if the whole route meets its design.
- Santa Fe Ultra70
- Better fit
- AprilAire E100
- Caution
Load and duct resistance justify the larger design
E100 has higher matched-condition capacity and fan airflow.
- Santa Fe Ultra70

Hidden installation without filter access
Both need a clear withdrawal path and routine care.

Cold conditions used to justify more capacity
Check each operating envelope and matched rating conditions. A larger warm-condition label is not a cold-space performance test.

What matters in practice
The differences that matter
The existing ducts can favor the smaller model or justify the larger one
Ultra70’s eight-inch collars can suit an existing appropriately designed route, while E100 needs ten-inch connections. Yet at a matched 0.2 inches water column, E100’s fan curve lists 245 CFM versus 140. Keeping old ducts purely to avoid work can therefore be the wrong saving if the load or resistance exceeds the smaller unit’s design. An installer should check the whole path. These airflow values do not establish how many pints either will remove through your installation.
How we reached this conclusion
Matched fan-pressure point and differing collar sizes crossed with replacement infrastructure. Airflow remains distinct from moisture-removal rate.
The low body does not make the trap disappear
Ultra70’s 12-inch cabinet sounds easier for a low attic than E100’s 15-inch body. Its manual requires the base six inches above the secondary drain pan for the P-trap arrangement. E100 has no external trap requirement. That can change which system fits after drainage is drawn. Both still need service access and protection over finished space. Do not buy the lower cabinet before the installer shows where its water will go.
How we reached this conclusion
Different drain requirements crossed with low headroom and finished living space. No complete enclosure height is calculated from incomplete clearance data.
Filter access is an ongoing job, not just an installation measurement
Ultra70 uses replaceable MERV13 media and calls for 13 inches of side filter withdrawal. E100 has washable MERV8 media and needs 15 inches on one side. If storage boxes normally occupy that space, both become harder to maintain. Choose the routine the household can sustain, including keeping replacements available or cleaning and drying washable media. Neither filter designation establishes a clinical benefit or whole-home air purification outcome.
How we reached this conclusion
Different media routines and side withdrawal distances crossed with long-term storage habits. No health or air-cleaning performance inferred.

Meaningful differences
What changes the fit
| What changes | Santa Fe Ultra70 | AprilAire E100 | Why it matters |
|---|---|---|---|
| Matched removal rating | 70 pints at 80 F and 60% RH | 100 pints at 80 F and 60% RH | The 30-pint increase concerns the stated test conditions. |
| Airflow at 0.2 in. water column | 140 CFM | 245 CFM | E100 supports more published airflow at that matched pressure. |
| Body and collars | 12 W × 28 D × 12 H inches, eight-inch collars | 14 W × 26 D × 15 H inches, ten-inch collars | Ultra70 is lower and narrower but longer. |
| Drain and filter | External trap and replaceable MERV13 | No external trap and washable MERV8 | Long-term care and installation differ independently of rating. |
What you give up
Every choice has a cost
If you choose Santa Fe Ultra70
- Plan filter replacements, trap, pan protection and any external pump.
If you choose AprilAire E100
- Include a drain hose, optional pump, duct changes and any external control in the total.
Recommendation switch
The decision flips if...
The smaller design is adequate and eight-inch infrastructure matters
Choose Santa Fe Ultra70. Ultra70 matches those requirements.
The verified load and duct pressure need more headroom
Choose AprilAire E100. E100 supplies higher documented capacity and airflow.
What matters in practice
Before you choose
You want enough capacity for the home without replacing a workable duct route or creating a hard-to-service installation.
What this comparison cannot tell you
- No fan-airflow conversion into drying time or health benefit. A2L requirements apply to current Ultra70.
