Query: Useless in protecting against odor

This was complicated to put together. Now that my child is on solids, it does nothing to contain the smell. By the end of the day the pail smells and so does the nursery. What's the use? I bought this hoping it would eliminate dirty diaper smell in the nursery, it hasn't lived up to my expectation. This is going into my next garage sale.
