  • It is a salt free unit meaning that it does not add excess salt waste into your water and environment.

Aquasana Shower Filter Reviews

Aquasana AQ-4100 Deluxe Shower Water Filter

The Aquasana AQ-4100 deluxe shower filters water through a 2 stage filtration process. Stage 1 involves the removal of chlorine and the balancing of pH levels. The pH level is both balanced and enhanced through the combined treatment of copper and zinc.

Water then goes through a coconut shell carbon during the second stage of filtration. It is during this process that synthetic substances and volatile organic compounds are removed.

It is just as well because these are the very substances that can be vaporized and absorbed through the pores of your skin. Also, inhaling them can cause adverse side effects. This filtration method will also remove chlorine as well as other contaminants.

  • It is very easy to install. The package includes a manual that instructs you through the simple installation process.
  • Aquasana claims the AQ-4100 is able to reduce 91% of harmful synthetic chemicals in city water and chlorine. The result of this is a healthier showering experience that leads to softer skin and shinier hair. See customer reviews
  • Filters last for up to 6 months before you need to replace them.
  • The unit also includes a deluxe shower head.
  • But you can also get the Aquasana AQ-4100 shower filter WITHOUT the shower head. This doesn’t necessarily mean that you will save money because both options are closely priced. But it’s a great option if you don’t need the extra shower head.
