Sanitary Toilet Seats are patent products of Kandy Environmentally Friendly Equipment Plant. Sanitary toilet seats replace the tubular sanitary seat cover which are put through the toilet seat to a'void direct touch of the toilet seat automatically under the control of a microcomputer, which protect the users from being cross-infected by using public toilets. And now they are widely used in where toilets are installed, such as airports, hotels, hospitals, schools, restaurants, recreation and entertainment places. What needs to be done is just to replace the original toilet seat by a sanitary toilet seat which matches over 95% of the existing toilet bowls. The wall remains what it is. Sanitary toilet seats are really gifts for the ones who use the public toilets frequently, for they can give each user clean and safe sanitary seat cover by giving a push to the button before sitting on the toilet seat. There is no need to worry about the filth and the germs any more!
