The Dehum Damppro 20 DYD-F20A is a discontinued refrigeration dehumidifier. CHOICE lists a claimed water-removal capacity of 20 L/day, but its exact-model test scores are available only to members, so the public evidence does not establish how well it performs or how it ranks against current models.
What are the Dehum Damppro 20’s specifications?
CHOICE lists these specifications for the DYD-F20A. The water-removal capacity and operating range are product claims, not guaranteed results in every home.
| Specification | CHOICE listing |
|---|---|
| Type | Refrigeration dehumidifier |
| Claimed water removal | 20 L/day |
| Claimed operating-temperature range | 5–35°C |
| Weight | 13 kg |
| Fan speeds | 2 |
| Recommended room size | Not recorded by CHOICE |
These are the public specifications on CHOICE’s Dehum Damppro 20 DYD-F20A page. The page does not provide an independently verified room-size recommendation.
Does it really remove 20 litres of water a day?
CHOICE lists 20 L/day as the model’s claimed capacity. That figure should not be read as a daily yield you can expect in any room: water collected depends on conditions such as temperature and humidity, and the public exact-model page does not show a verified household result.
#1 Best Overall

Sleek design fits bedrooms, bathrooms, closets, dorms, apartments, and RVs. Move it easily for targeted moisture removal—perfect as a small room dehumidifier, quiet dehumidifier, or portable moisture remover.
CHOICE says its dehumidifier comparisons measure water removed in three runs at different conditions in a controlled chamber, reflecting humid winter climates: 8–16°C and 65–90% relative humidity. Those conditions help explain why capacity figures can vary across tests, but the published method does not reveal the DYD-F20A’s individual results. See CHOICE’s dehumidifier testing and comparison information.
Is the DYD-F20A any good?
The public evidence is not enough to give it a performance verdict. CHOICE includes the model in its review material and describes its controlled-chamber testing, but the DYD-F20A’s numeric scores are behind membership access. Its inclusion in a comparison is not evidence of a high score, a test win, or strong performance against current products.
