What is the difference between Fernox MB-1 and F1?
The Protector MB-1 4 litre and Protector F1 500ml are both Buildcert approved inhibitors and are equally as effective in protecting the system from the effects of corrosion and limescale. Both products treat 100 litre systems or 10 single radiators. The MB-1 is a heritage product and its formulation requires a larger unit pack size but it has a loyal customer base and as such has a place in the market. The Protector F1 500ml is a concentrated product which is favoured by installers and homeowners who prefer to use smaller packaged products, which are easier to handle and transport. The efficacy of both products is the same. Another example might be washing powders, which are available as loose powder, gels, liquids and tablet form in varying pack sizes. It is a matter of personal choice which product to buy.
