The Aquasana AQ-4100NSH is a shower filter that is used together with your existing shower head to provide you with the healthiest shower experience. It also instantly improves air quality since the harmful chemicals from shower water that might evaporate in steam and contaminate the air will be eliminated.


AQ-4100NSH is made from a patented copper-zinc media and coconut shell carbon. It enhances your water’s pH balance and reduces more than 90% of chlorine in shower water as well as the synthetic chemicals that can cause damage and excessive drying to your skin and hair for a softer, more moisturized skin and shiny, healthier hair. 




Smart design

It has a unique upflow design to prevent clogging, to retain water pressure and shower head height, and to increase water contact time with filtration media for greater filtration.


Easy Installation

It can be quickly attached to your existing shower pipe. You can use your own shower head as long as it’s up to 4.5” in diameter and 2.5 GPM.



The system is tested to NSF/ANSI Standard 177.


Saves money for bath products

The filtered shower water will naturally enhance your body products and hair treatments. Save money by using less shampoo, conditioner, soap and other bath products.
