Drinking chai in kulhad is way more hygienic than drinking in glasses and cups that have been used and washed again and again. Kulhads on the other hand, are for one time use only. The threat of spreading bacteria is high when drinking chai in used glasses from tapris. The muddy kulhads are disposed off the moment one finishes off the chai and thus one is not exposed to diseases as bacteria don’t spread though kulhad wali chai.
