The other day, in Costco, I saw a bunch of Purwater
water-filters (for eg glasses of water -- screws onto
kitchen-sink faucet -- manual turn-on for filtered
water, then switch back off again.

Anyone know anything about it?

How good at getting all the bad-stuff?

Any chance of getting all the medical drugs that
people pee out and ends up in reservoir and then
in my faucet?

THANKS!
