Good and Inexpensive water filtering
I bought this 6 years ago. It's a standard design that has been used for maybe 40 years in labs to filter tap water for purity reasons. The new shut off valve in the top is a good idea. I use it under the sink instead of whole-house. The $5 carbon filter has to be changed about once every 6 months before the bad taste of tap water starts to come through again. If you haven't installed a faucet before, think twice before installing this under the sink. Even with experience it took me all day finding parts, going back to the store to get a flaring tool, cutting pipe, and fixing leaks. Open end wrenches for each nut was much better than my best adjustable wrench which was too thick to get in place.
The water goes in at the top from the side and down the walls of the heavy duty clear plastic (marked PPT on mine). Water pressure forces it through the filter which fits in the middle. The water returns back up in the middle to exit on the opposite side of the cap where it came in. The design allows for a large surface area (which does not reduce water pressure) and about 1 inch of filtration thickness. It's a heavy duty plastic.
I don't have it whole-house because because I want the chlorine to remain in the pipes as long as possible, so it's under the kitchen sink. Reducing the 3/4 fitting down to 1/2" under the sink was a pain with my copper tubing. It required carefully selected parts including 3/4 to 1/2 reducer (male on both ends), two 1/2" nuts, 4 sleeves, extra pipe, and a miniature pipe cutter. I could only find the "flared" reducer (a pointy end on the 1/2" side) so i didn't need the sleeves, but I had to go get a flaring tool. For whole house use, installation is probably easier, but the $5 carbon filters don't last as long.

Awesome filter
I was lucky enough to already have one of these installed in the house I bought in 2004. Just the thing for a well water system. The drinking water gets further refined by a reverse osmosis filter, but no sediment in any of the water in the house.

Love it
5 stars for a water filter?
Well my current one conked out, and this is the replacement one that fits my existing filters. Best price I could find, no tax, no shipping. Sometimes Amazon really amazes me with the amount of stuff you can find here.
Unbolted my old filter, bolted this one in, and saved myself a fortune in plumbing costs. And the $50 worth of cartridges I have won't go to waste.
Couldn't be more pleased with both the product and Amazon
