Sizing data guide
What up to 1,000-7,200 sq. ft. actually tells you, and what it does not.
Manufacturers often publish maximum recommended square-foot coverage for crawl-space and whole-home dehumidifiers. Those values are useful because they show the manufacturer's intended sizing range, but they should not automatically be treated as directly equivalent engineering ratings across brands.
Real-world moisture load can change with temperature, climate, air leakage, enclosure tightness, ventilation, drainage setup, crawl space height, and installation details. Two manufacturers may also use different assumptions when translating moisture-removal capacity into a square-foot coverage statement.
DrySpace treats coverage as manufacturer-reported sizing guidance. The site does not claim manufacturers are deceptive, and it does not invent a universal square-foot methodology where the source data does not provide one.
This table is generated from the current DrySpace product records. Missing values are shown as not verified instead of being treated as zero, and AprilAire's separately labeled rated capacity remains distinct from AHAM capacity.

Products represented: 26. Products with unverified coverage excluded from the table: none.
Products in the same broad rated-capacity band can carry very different manufacturer-listed coverage values. That does not prove one value is more honest; it shows why coverage claims should be read with rating conditions, source notes, and intended application.
Models can share the same AHAM capacity and manufacturer-listed coverage while differing in drainage configuration. A built-in pump may be the deciding constraint when condensate must move upward or farther away.
AprilAire records in DrySpace include broad manufacturer coverage statements for crawl spaces, basements, or whole houses. The normalized records keep those headline claims visible without replacing them with an invented crawl-space-only calculation.
Square-foot coverage is not the only field that needs context. DrySpace distinguishes AHAM capacity, separately published rated capacity, and maximum or saturation capacity. A product advertised around a 145-pint maximum claim may publish a much lower AHAM value under moderate test conditions.
For a fuller explanation, read AHAM PPD vs maximum PPD.
The current AprilAire records show headline manufacturer coverage statements that include broader whole-home or multi-space positioning, while their moisture-removal capacity is stored as separately labeled rated capacity rather than AHAM. Their maximum or saturation PPD fields remain unknown because the current normalized records do not contain verified maximum-removal values.
DrySpace has not imported a separate regional, loose-building, or tight-building AprilAire sizing table into this guide. The official AprilAire source links remain attached to the product records, and the headline coverage values are not silently replaced.

The crawl-space sizing assistant uses manufacturer-listed coverage as one verified eligibility signal. It does not represent that field as an independent DrySpace engineering calculation.
The assistant also considers floor area, built-in pump requirement, and verified minimum operating temperature when a temperature is entered. Moisture condition and crawl-space condition inputs are used for context and warnings, not a hidden capacity multiplier.
Filter the verified catalog by floor area, pump requirement, and minimum temperature.
Sort and filter the full database without treating missing values as zero.
Understand why pint ratings can differ before comparing coverage claims.
Use drainage constraints to decide which configuration matters.
See how floor area works alongside drainage, temperature, and moisture context.
DrySpace uses manufacturer documentation and official sources already represented in the product database. Verification dates are recorded, unknown fields stay marked as not verified, and conflicting manufacturer values are surfaced rather than resolved by guessing.
