SpaBoss Filter Free

SpaBoss Filter Free is a granular Hot Tub Filter Cleaner that gets your filter clean & operating efficiently.  It has a pH colour indicator that turns the water red when the solution is strong enough and ready to use.

Filter Free is great for any kind of Spa filter, sand DE or cartridge. When used regularly, Filter Free Filter Cleaner helps to reduce chlorine or bromine demand by removing those unfilterables.
