Product review (5 stars): This is what I imagine fresh, cool, spring water tastes like.
I've been using this brand water filter for years, changing out every six months like clockwork, and it's the only one I ever use. One, because it's made in the USA, two, because the water coming out tastes delicious, and three, because the price is very reasonable.

I refill and empty a large pitcher repeated for five full minutes after I first install the filter, as per instructions, and I've never experienced any kind of off-taste or color; just pure, clean water. I'm concerned when I read of people who flush only a gallon or so, especially when they mention that the water is gray and tastes a little off. Flush a full five minutes, folks!

The reward is what I imagine fresh, cool, spring water tastes like; so refreshing!

 Every Water Sentinel water filter I've had installed easily and removed easily (I've never gotten around to using the O-ring lubricant) and I've never had a leak. I highly recommend this filter.
