I used to have to purchase bottled water, but no longer. I can now enjoy pure, clean water from my home. I love this filter, I no longer have to refuse to use the water that comes out of my kitchen faucet, as I know it is safe to use and drink now that I've found this fantastic filter. It filters out all of the dangerous contaminants that tap water contains, plus it filters out any radiation that might be present. Thank you for a great product that assures me of safe, clean water.
