The BiWorld Smart Mag Compact Filter Chemical Pack is a complete solution for protecting your central heating system from sludge, scale and corrosion. The filter uses powerful magnets to trap ferrous debris, such as magnetite, which can cause blockages and reduce the efficiency of your system. The chemical pack contains two products: B3 Cleanser, which removes existing sludge and scale, and B1 Protector, which prevents further build-up.

The filter is easy to install and maintain. It can be fitted on either the flow or return pipework and has a built-in isolation valve for easy servicing. The chemical pack is also easy to use, simply add the required amount to your system and circulate for the recommended time period.
