- Not verified
Because this model does not have a verified built-in pump, a suitable gravity-drain path may be required unless another external condensate solution is used. That can be fine when the unit can drain reliably downhill.
A pump configuration is not universally better than gravity drainage. The practical choice depends on the crawl-space layout, drain route, and where condensate can safely discharge.
Coverage and sizing context
Manufacturer-reported maximum coverage
The stored manufacturer-reported maximum coverage for this model is 5,500 sq ft. This is not a DrySpace sizing guarantee. Crawl-space height, sealing, climate, airflow, moisture load, and water intrusion can all affect whether a product is practical for a specific space.

DrySpace leaves missing or conflicting information marked as not verified rather than choosing a value without support from the current product record.
Official sources
Verification notes
- The 100 pints/day capacity is stored as rated capacity, not AHAM, because the reviewed E100 sources did not label it as AHAM.
- AprilAire current sources conflict for the E100: the current AprilAire FAQ and E080/E100 installation-guide mirror list 6.9 A, while a mirrored E100 specification sheet lists 6.7 A. DrySpace stores the FAQ/manual value and notes the conflict.
- No AprilAire maximum/saturation PPD value was found, so maximum removal is intentionally unknown.
- Energy factor values from the specification sheet are not stored in the Integrated Energy Factor field because DrySpace tracks IEF separately from energy factor.
