More Features: It removes chlorine, lead, mercury, pesticides, and herbicides from water to make it pure and clean. Even it improves the taste and removes odor from water.

Aquasana Water Filter with Carbon and KDF filters

Usage: There are very few companies offering filtration systems for the entire house. If you do not want to compromise on the water quality for any household tasks other than washing and watering your garden, then this is the best option for you. It is also perfect for drinking purposes and saves you from the hurdle of attaching a separate filter on your tap or getting a pitcher/dispenser for your drinking water. Bathing from filtered water will improve your skin and hair quality in a concise time.  

Efficiency: This filter removes 97 percent of chlorine and other harmful elements in water like lead, mercury, pesticides, and herbicides. The carbon and KDF filters are designed in such a way to leave the healthy minerals in the water and reduce the harmful contaminants. This filter does not reduce the total dissolved solids (TDS) from the water.

Capacity: The whole house filtration systems usually work for an extended period. This model is good enough for 10 years or 1 million water gallons. The pre and post-filters work for 3 months and need to be changed for a better flow rate.

Design and Installation: Installation is easy and is explained in the user manual, which comes with the package. It comes with all the essential elements needed for installation. Design is simple, and there is no complexity in understanding the system and dealing with it later on.

Our Rating and Verdict: As this filter does not remove the dissolved solids, so it is not as efficient as other competitors when it comes to drinking water. It is perfect for bathing, washing eatables, and cooking purposes. We give it a 4/5 rating.
