The smallest drying capacity of washer dryers of this age and spec is 3kg and the largest is 14kg. At only 5 kilograms, the CDB 485DN has a quite small drying capacity compared to most of the other similar spec washer dryers that were released more than two years ago.
It may also be worth considering one of the alternative 5kg drying capacity washer dryers currently available including because of it's better review score, the Samsung WD806U4SAGD.
Washer dryers with a larger drying capacity that might also be worth looking at include the AEG L87696WD (£449) (6kg).
