ConsumerReports.org evaluates 25 small-, medium and large-capacity dehumidifiers.

Models are ranked against others with similar capacity and Recommended and Best Buy dehumidifiers are named.
For those that don't have a ConsumerReports.org subscription, Mary H.J. Farrell shares some bullet points from the site's testing in this free article. She notes that most of the dehumidifiers tested did pretty well in their core task of taking moisture out of the air. "Where they differed was in the accuracy of their humidistat, their performance in a cool room, and their noise level," she notes. The best-rated small, medium and large dehumidifiers are named, but no specific information is shared.
The anonymous nature of this site gives us pause, but digging in deeper reveals DehumidifierBuyersGuide.com to be one of the better dehumidifier review sites on the web. Testing is hands on and the methodology and rationale behind the tests are described in excellent detail. The individual reviews are even more detailed, with performance, usability, portability, durability and more given attention. Dehumidifiers are organized by capacity and top performers -- and in some cases, models to avoid -- are named.
Kevin Purdy conducts 40 hours of research and weeks of "real-world testing in century-old stone basements" to find the best dehumidifier overall, as well as an alternative. Methodology is well explained, but only four dehumidifiers make cut to the testing phase, which makes this source a little less comprehensive than the ones above.
AllergyBuyersClub.com offers a wide selection of dehumidifiers for consumers who suffer from allergies. Anonymous expert reviewers rate each dehumidifier on various factors, including moisture removal, noise level, operation in low temperatures, drainage, and energy use. However, it is not clear whether the dehumidifiers have been subjected to any hands-on testing. Reviews from owners are also available on this site; while most dehumidifiers have only a handful of reviews, a few get considerable feedback.
Amazon.com is a good source for reviews on a wide variety of dehumidifier brands. Many models have accumulated at least some feedback, while others have received hundreds or reviews, and in some cases thousands. Among the latter, Frigidaire branded dehumidifiers receive great feedback, with strong scores based on thousands of reviews across various models and sizes.
A former HVAC service technician and contractor offers his opinions on the various brands of whole-house dehumidifiers, but specific models are not addressed. Santa Fe dehumidifiers are singled out as the very best, though several other brands rate just as highly.
HomeDepot.com has a good selection of dehumidifiers. Many get some feedback, others get dozens, hundreds or even thousands of reviews, though those also include reviews originally posted at the manufacturer's website. In addition to an overall rating, some reviewers leave sub ratings for quality and value, and say whether or not they would recommend their dehumidifier to a friend.
BestBuy.com is another good destination for user reviews of dehumidifiers. We see less feedback here than at some other sites, but feedback and ratings from BestBuy.com users is presented separately from any reviews from manufacturers and are unique to the site. Nearly 50 models are listed.
AchooAllergy.com, an online retailer of allergy, asthma and sinus-relief products, sells several brands of dehumidifiers. Experts at the site have reviewed some of these models and discuss their pros and cons on the site, but they do not make any specific recommendations.

Sylvane.com, an online retailer of air-quality products, sells many brands of dehumidifiers and allows users to leave reviews. Most models don't receive much feedback, but a few get dozens of reviews and some amass well over 100.
A number of dehumidifiers sold at Walmart.com have accumulated a few dozen reviews or more, and some have received feedback from more than 100, or even thousands of users. Several Frigidaire models stand out with high satisfaction and lots of reviews.
Sears.com is another retailer site with lots of dehumidifiers and many user reviews. However, while there are more than 400 models listed, only a little more than 40 are sold by Sears itself. As is the norm, reviews include those from Sears.com users as well as those posted at manufacturer sites in some cases. One exception is Kenmore dehumidifiers, which is the Sears house brand. If you are considering a Kenmore dehumidifier, that makes Sears.com a must-see stop for user feedback on reliability, usability and other factors.
