The P1 retains essential minerals your body needs. These minerals improve the taste of your water and act as electrolytes that help your cells absorb and use water more effectively.
Reducing chemicals like chlorine and disinfection byproducts can significantly improve the taste of your coffee. At the same time, minerals play a crucial role in extracting flavor from the bean, which is why better coffee starts with better water.
Boiling does not reduce all contaminants. In some cases, it can increase the concentration of contaminants like lead as water evaporates and the total volume of water is reduced, which matters for soups, pasta, tea, and oatmeal.
We wash produce to remove pesticides, dirt, and cross-contamination, but the water we rinse with matters too. The P1 helps create a cleaner rinsing process so you are not adding excess contaminants back onto your food.
If you do not drink from your tap, your pet probably should not either. Chlorine and other harmful byproducts can affect the taste of their water and can contribute to long-term stress on certain organs, especially in smaller, more sensitive dogs.

We’re so confident you’ll notice a difference in your water that if your system does not perform as intended, you can return it within 30 days of purchase.
