I was shocked by the pricing of these water filters from the recommended dealer we purchased the fridge freezer from and also across the few other websites that stock this newer internal type. After finding this company on th web I rang to be sure

Quick efficient delivery. Filter seems to be working well, although the very nature of the product relies on the filter doing the job it is designed to do. There is no way I can check its efficacy as a customer without access to laboratories!

Ordered on Saturday, delivered on Tuesday, that's good service. The water taste from the 3M filter appears to be the same as from the original Bosch filter, and less than half the price
