Thanks for your reply. This is perfect, just the sort of advice I was hoping for.

How often did you have to replace your filters in Soton? I guess you had to be very careful as infants were consuming from it.

Filters I am using are Super Sterasyl. these are made in UK. I have not come across the black ones you mention. What are they called and what advantage do they offer?

I asked about the cold weather performance as my preps allow for the house to go cold if necessary in winter months and at times I may not be able to stop the filter element from freezing. I was worried that it might disintegrate.

Thanks again. Your fast reply is very much appreciated.

Hi LS!

I replaced them once in the whole time we ran it. I was using the Super Sterasyl ATC filters. Did not notice a change in the taste or quality of the water (not that I tested it through any scientific means!) before or after the change, so I probably changed them unnecessarily. I'm not sure if these filters clog up like other makes do to stop dirty water getting through though.

The black filters are Berkey Black Elements. They are by far the best you can buy (as they should be for £90ish a pair!) and can remove red food colouring from water, and you can fit the fluoride underfilters to remove 90-something percent of the fluoride in the water.

The super sterasyl filters are ceramic, so there's always a risk of them freezing and cracking, but I think the size of the water particles may reduce this.

I have a couple that I've taken out at home, if you want I can give them a thorough soaking then pop them in the freezer, see what happens.
