Getting a new Fridge/Freezer for the kitchen and it's going to be plumbed in and have filtered water. Is this any good for brewing or should I still treat it? although it would be an unknown as opposed to mains which I have a report for.
TIA

Re: Using Filtered Water
Depending on the type of filter used which are normally just active carbon, these will only remove chlorine so you'll still need to make adjustments.
It is cheaper to treat chlorine with campden powder though so not really worth it.
If the filter is also ion exchange e.g. removes carbonates, you'll need to know the content of the post filtered water before deciding what is required.

Re: Using Filtered Water
It will probably be an activated charcoal filter which as AnthonyUK says, will remove chlorine, solid precipitates and also any organic compounds in the water. It won't have any effect on salt concentrations (chloride, sulfate etc...)
If it has an ion exchange resin - it most likely WON'T reduce the alkalinity of your water - what they usually do is exchange the Calcium for Sodium (or potassium) so that the carbonates become more soluble and won't precipitate on heating. This can have an effect on the flavour of the beer if you have hard water due to the increased sodium - it also strips the calcium and magnesium out.
Check exactly which type it is. I would suggest that an active carbon filter can only be a good thing. In any case, I would do a salifert test on your post-filtered water.

Re: Using Filtered Water
I use a 3 stage filter, which includes a active carbon type that will be on your fridge.
It has no effect PH, it's just removes chlorine, sediment, pesticides and heavy metals amongst other things.
