Humidex dehumidifiers can be purchased online through mass retail sites such as Amazon as well as from auction sites such as eBay. The Humidex website also contains a list of authorized dealers, including Home Hardware, Kent, Steers and JT Martin & Sons, as of March 2015.
When shopping for Humidex dehumidifiers on Amazon, users have the option of sorting results based on price range, customer popularity and by the highest-selling items. Each listing on the site contains a picture of the product as well as a detailed description of its available features and functions. Listings also link to a product-specific, question-and-answer section, wherein Amazon users are able to pose questions about the product to the community. Questions typically focus on details and scenarios not covered in the product description, such as its ability to function in certain environments or its performance compared to other models.
The amount and quality of the information provided in each listing on eBay varies from seller to seller, which means that in some cases buyers may need to contact the seller directly to ask questions about the item. Any messages sent to a seller should contain as much information about the specific listing as possible to ensure the most accurate and thorough response possible.
