5 x (Twin-packs - top & bottom) of filters to fit the CANADIAN SPA HALIBURTON & MUSKOKA models of Hot Tubs.
The FILTRATION MATERIAL is made in GERMANY and is THE BEST QUALITY AVAILABLE. Same filtration characteristics as the old filters ( 1 X 10ppi + 1 X 20ppi filters) but more resistant to chemicals. In our tests we have found that these filters last about 25% longer than the old types.
Better quality and about half the price!
