500g PureFlow B-stock in various dimensions (waste) is ideal for heavily polluted water, e.g. for initial cleaning at the start of the season or for final cleaning after the bathing season.

Use the cost-effective B-product for coarse dirt in the pool, pond, stream or even for your cistern and then start a new, crystal-clear bathing season with PureFlow POOL 3D filter elements.

The B-stock is ideal for protecting your high-quality filter material from heavy contamination and thus extends its service life.
