I would like to buy a water filter and could use some advice.
Is the NSA sufficiently better than the inexpensive Brita
to be worth the extra money? Both are activated charcoal
systems. Is there any other system I should be considering?
Is there any risk that by running my water through charcoal
I may put something _into_ it that isn’t already there?
I am mainly concerned about lead and chlorine in drinking
water. Do activated charcoal filters remove these things?
Are there other things in water I should be worried about?
Thanks for any help any of you can give me!
