Water filters have been around since the mid-1700s, varying from all different styles and sizes. Although there are several types of filters, the most common ones include a combination of carbon absorption and 

ion-exchange. 

Background

Carbon easily absorbs contaminants and other wastes in water because of the many tiny holes and cracks on its large internal surface. Using activated carbon is a cheap and effective solution to purifying water. 

Ion-exchange uses small polymer resin beads that contain sodium. When water passes through, the calcium and magnesium present in water binds to the polymers as sodium is exchanged into the water. This helps soften the water so that it removes the taste of chemicals.

The First Test

The First Test

The idea from the beginning to was to incorporate mechanisms that are in a shower as the flow of water is easily able to be controlled. However, it was important to test this idea to determine its effectiveness.

How effective are showers in conserving water? 

According to a Texas Study: 

"A standard showerhead flows at a rate of 2.5 gallons per minute. This means that a ten minute shower only uses 25 gallons of water. A full bath can use up to 70 gallons of water. Using these numbers, a shower will use less water in most cases."

AquaGear utilizes both methods: filters and water flow settings. Water will pass through a mixture of carbon fillings and polymer resin to ensure clean water.
