Editorial Policy
Written by the Dehumidifier for Basement editorial team and reviewed for source accuracy. Last updated July 2026.
Everything published here is written to one rule: a reader should be able to check any factual claim against a source we name.
Approved sources
We rely on the following, roughly in this order of preference:
- U.S. Environmental Protection Agency
- ENERGY STAR
- U.S. Department of Energy
- U.S. Energy Information Administration
- CDC and NIOSH
- AHAM
- ASHRAE
- Official manufacturer manuals and specification pages
- Government and university extension publications
Sources are kept in a single registry so a changed URL or a new verification date updates every page at once. Current registry entries:

Fact-checking process
Before publication, every numeric claim is traced to a named source, every product specification is matched to a manufacturer page or a government listing, and any figure that cannot be traced is either removed or labeled “Not published by the manufacturer.” Approximate conversions — such as comparing capacity ratings from before and after the federal test-procedure change — are presented as approximate and model-dependent, never as exact equivalents.
Product verification requirements
- Exact model number required; generic product names are not published.
- Specification source URL and verification date required for every entry.
- Specifications are never copied from one model to another.
- Prices are shown as ranges and labeled subject to change.
- Discontinued or unavailable models are not presented as primary recommendations.
Prohibited claims
We do not write “we tested,” “lab tested,” “our testing found,” or “proven best,” because we do not run a laboratory. We do not publish fabricated credentials, placeholder expert names, invented certifications, fake ratings or review counts, or structured data for people who do not exist. We do not promise that a dehumidifier prevents or cures illness.
Update process
Pages carry a last-updated date. Sources are re-checked when a page is revised, when a federal standard changes, or when a manufacturer alters a published specification. Product prices and availability age fastest and are treated as indicative only.
Corrections
Errors are corrected promptly and noted where the change is material. See the corrections policy for how to report one.
