Great Product

My boat is now sleeping for the winter and guess what? There was not one complaint from "The Crew" this past summer about the "Head Smell". The No-Stank Filter was extremely easy to install and performed perfectly! It works as advertised. There is nothing else I can add. Thanks for a great product.

Yes Canadian boat holding tanks also smell

Rick Sheppard British Columbia Canada, yes Canadian boat holding tanks also smell, not mine anymore, before installing the no stank filter I had tried two other makes both twice the money and complete throw a ways they worked I would say about fifty per cent of odor removal, the no stank is exactly that no stank, and half the money what more could you ask for, smelling like a rose in Canada.
