{ } One of the Independent's 10 Best Eco Cleaners (May 2012). Made in Germany from special high-grade stainless steel, Smellkiller does not cover odours, it neutralises them as it comes into contact with air & water, leaving the air fresh & clean again. No chemicals or refills are required. Simply hang the Smellkiller on the inside of your toilet so that each time you flush, water runs over the Smellkiller. It really works. You will need to clean the Smell Killer from time to time to ensure optimum performance. View all the eco products in our section, or click on any of the links on the left hand side to see more.
