One of the first things we did when we came up with + POOL was break apart a Brita filter. We had no idea what they were made of and how they worked, we just knew that they removed particles to create great tasting water!
The primary filtering mechanism for a Brita filter (or any drinking water filter) consists of activated carbon and ion-exchange resin. A sieve rests at the bottom which also serves as a filtration layer.
+ POOL’s filtration system is similar in that it allows water to sift through a series of materials to remove bacteria and pathogens. Click here to download a diagram of + POOL’s newly patented filtration system.
