How we pick
Each buying guide on Damp and Dry covers one type of product and compares five to eight listings. This page explains how that shortlist is made and what the comparison is based on.
In short
We read the listings, not the products. The picks and descriptions are based on what the Amazon listings and the manufacturers state. We have not handled, measured or tested the products ourselves, and our pages never claim otherwise.
What goes into a buying guide
- The right type of product. A product has to answer the question the guide asks, not just be loosely related to the topic.
- Facts from the listing.Dimensions, materials, power and what is in the box come from the listing. Where a detail is missing, the table says "n/a" (not stated).
- No prices on this site.Prices change often. You can see the current price on Amazon with the "Check price on Amazon" button.
What the labels mean
Labels such as "Best overall" or "Best value" are our reading of the listings, not test results and not customer ratings. The order is an editorial judgement of how well each listing fits the job.
What this method cannot tell you
- How many litres a day a dehumidifier really extracts in your room: makers quote it at their own test conditions, often 30 °C and 80 % RH, which a British winter room never reaches.
- How loud a unit sounds at night in a small bedroom, beyond the decibel figure on the listing.
- How evenly a heated airer warms its rails and how long it lasts with daily use.
- Whether a dehumidifier will clear a damp problem caused by a leak, rising damp or a building defect.
For those questions it is worth reading recent customer reviews on the listing itself. The "Good to know" list under each product names what the listing leaves open.
When a product disappears
If a product is no longer available, we replace it with a comparable one at the next update. Page addresses do not change.
