Don’t want to reuse a filthy used mask? What makes Totobobo special? Used and abused, it can still be as good as new!
Typical N95 masks are disposable and designed for one-time use. It is fine for an initial couple of times, but anything beyond that the mask can become disgustingly dirty and/or have bacteria growing on it.
Cloth based masks are washable, but it is questionable if the filtration power still holds after multiple washes, and you do have to wait at least hours to get it dry enough for reuse. Totobobo mask is a plastic base, very easy to wash clean and dry, for instant reuse. Just change the filter and the mask is as good as new with full filtration strength to go again!
