Product Comparison

There really isn’t much of a comparison when you line up the AQ-4100 with other shower water filters. Other leading brands only filter about 50% of the chlorine from your shower water. Aquasana takes care of more than 90%. Another common disadvantage with other filters is that the water pressure can be significantly reduced. Some other products actually lower the height of your shower head which can make for an awkward showering experience. Many do not even have a second stage carbon filter. The Aquasana filter also comes with a 90-day satisfaction guarantee and a 1-year warranty.
