Hahn Water Filters: Product Reviews

Hahn Whole House System and Descaler

Hahn whole house water filter review

Whole house water filters are great appliances to keep in your home. They provide clean water not only for drinking but for bathing and all of your household needs.

Functions

When the water reaches the filter, it has to pass through four stages. First, it comes upon a 20-inch 20-micron mechanical filter, which gets rid of slit and larger undissolved particles. Next, the water moves through a tank that removes chlorine. After most of the chlorine is removed, the water reaches the third stage (the second tank), which is a descaler. The descaler protects your pipes from corrosion and extends the life of your appliances. The fourth step in the system is a 10-inch 1-micron filter, which eliminates even the smallest particles.

Here are some key things to note about the product:

  • Flow Rate: 10 gallons per minute.
  • Filter cartridge included with a life of 72 months.
  • Includes a filter change indicator.
  • The optimal pressure range is between 20 and 100 PSI. Not be used if pressure exceeds 100 PSI.

Customer Service and Warranty

First, we should mention how amazing the Hahn customer support team is. They offer live support via phone, chat, or email, and have an excellent return policy. Additionally, the company offers a lifetime warranty and a 120-day money-back guarantee. It is important to note, however, the unit must be installed by a licensed plumber to validate the warranty.

Pros
Amazing filtration
Easy to install
Almost no maintenance
Cons
A bit pricey
