About Dehumidifier Sizing

Dehumidifier Sizing is an independent reference and calculator site focused on clear, current guidance for sizing residential and light‑commercial dehumidifiers.

What this site is

• A plain‑language explainer of DOE 2019/2020 rating changes and how they affect pint‑per‑day capacity labels.
• Modeled sizing tables that translate space type, approximate square footage, and moisture conditions into recommended capacities.
• A curated set of primary sources with dates and context so you can verify claims.
• Occasional comparisons and explainers to help you reason about performance tradeoffs.
• Funded by affiliate links where noted; independence and disclosures are documented on the disclosure page.

What this site is not

• Not a manufacturer, retailer, or warranty provider.
• Not a contractor or design service; always confirm against the manufacturer’s performance tables for your conditions.
• Not a law or compliance advisory; ENERGY STAR and DOE specifications evolve — check the latest source documents before making decisions.

How recommendations are estimated

Portable recommendations combine DOE/ENERGY STAR guidance with simple moisture‑load heuristics across three moisture bands and common space sizes. Whole‑home guidance is directional and points to published manufacturer tables — always size against the performance data at your target temperature and relative humidity.
