Bests & Worsts Reviews from Amazon

I originally had a $45 filter that did a great job removing chlorine and hardness from my water, but it clogged up enough after 3 months that the flow was 1/5th what it was without the filter. So, looking at $45 per quarter, I checked out a Culligan filtered shower head. This filter didn't clog, but in one month my hair started getting wirey from the local hard water. (How Culligan can claim 10,000 gal. lifetime, I do not know.) This filter costs about $15, so the price per month seemed to be the same. BUT, the Culligan filter is a resin filter and can be revitalized, as anyone who has a resin softener on their espresso machine knows. Just half-fill a glass that will hold the filter with cold water, dissolve 2-3 teaspoons of salt, and soak the filter for 20-30 minutes. Rinse and it's good as new! This makes the Culligan filter a deal, at least for my water. For those who want to know, the sodium in the salt replaces the minerals that have been removed from the water and stored in the resin. This restores the resin to its original condition, ready to absorb more minerals from your water.
