Several years ago I used a Britax water filter as I thought it might be healthier, but quite honestly I came to realise that I'd been brainwashed. (Excuse the pun).
I now reckon that the minerals in tapwater are beneficial and shouldn't be filtered out.
Ok, my tap water did taste a bit odd, but hey! you get used to it, and now my tap water is my drink of preference. Nectar of the gods.
We pay a lot of money to have healthy tap water; that same healthy tap water is used to flush our loos! Why pay more for an additional dubious benefit? Especially when lots of people globally would give their eye teeth for water as good as ours, on tap, every minute of the day and night.
Get real, people, and recognise when you're being duped.
Plus, don't even get me started on bottled water!
