Practical guidance for a drier home
Home Air Compass is an editorial project for readers in the United States who want to understand household humidity and make informed decisions about dehumidifiers. Our guides start with basement questions: what to measure, what to record, what a device may cost to run, and what to check when planning drainage.
Who prepares our guides
Our articles use the byline Home Air Compass editorial team. We use AI assistance for research, organization, drafting and calculations. Our publishing process requires human review and approval. AI output is not evidence by itself, and we do not present invented authors, credentials or portraits as real people.
Sources and practical tools
We draw on public guidance from relevant agencies, including the U.S. Environmental Protection Agency and the National Weather Service, technical information from ENERGY STAR and the U.S. Energy Information Administration, and manufacturer documentation where advice depends on an appliance.
We link sources where they support a point. A manufacturer’s instructions apply to the models and conditions described; check the manual for your own equipment. Our calculations show their inputs and assumptions so you can substitute your own values. Worked examples and illustrative scenarios are not measurements of a real home.
We do not describe a product as tested by us unless the guide provides the product, method and results of that test. A humidity observation alone does not establish the cause of a leak or a moisture problem.
Corrections and updates
If you find an error, an outdated reference or a calculation that is unclear, please use our contact page. Our corrections policy explains how we review reports and describe significant changes.
