Product review (5 stars): Unbelievable price.
I purchased this model specifically for these three reasons: 1. Price for the housing and cartridge for 3000 gallons or one year is considerably less than many cartridges alone for 600 gallons or six months. 2. This particular model doesn't come with a faucet, so I can use my own high quality separate faucet. 3. This model is permanently connected to line pressure, 30-100 psi OK, so I don't need a fancy three hose faucet to disconnect pressure when the filter isn't in use.

Since our water is pretty good already, and we really just wanted to get rid of the chlorine, this filter was an excellent choice, far far FAR less expensive, both initially and on an annual basis, compared to filters which take out all manner of sub micron particles and chemicals.

This unit was a snap to hook up, just needed to purchase about $12 of fittings and hose at Home Depot. The hose just plugs right into the head/housing with no tools. The cartridge couldn't be easier to change, just rotate 90 degrees and it automatically shuts water off and pops out. Tap water tastes much better after going through this. I've seen the argument that tap water in the USA is already good enough and it's a waste of money/time to use any water filter. Even if that were true, at $15 for the first year plus $12 a year after that, I don't see how that argument really has a leg to stand on! $1 a month for chlorine free water is great!!
