Items like towels usually don't require frequent washing due to contact with one's skin -- you're generally clean when you touch one. The fibrous fabric is more at risk of gathering bacteria after it's assisted in patting you down, when the cloth remains wet in a steamy washroom.
The Puredesign Dry Clean prevents this invisible soiling of your bath towel by helping it to shed its moisture more quickly. The rectangular ring can accommodate a pair of towels side by side, blowing hot air downwards and in between their folds along the lower bar.
Additionally, the cylindrical fixture of the towel rack features a UV light. This functions as a sanitizer to keep the cloth hygienic between proper washes.
