Brita pitchers and filters use a process called ion exchange to remove impurities from water. This process involves using a special type of resin that attracts and holds onto certain ions in the water, replacing them with other, more desirable ions.
Here's a breakdown of how it works:
1. The Filter Cartridge
- The heart of a Brita filter is the filter cartridge. This cartridge contains a blend of activated carbon and ion exchange resin.
- Activated carbon is a highly porous material that acts like a sponge, trapping impurities like chlorine, sediment, and taste and odor-causing compounds.
- Ion exchange resin is made up of tiny beads that have a positive or negative charge. These beads attract and hold onto positively charged ions like calcium and magnesium, which contribute to hard water.
2. The Water Flow
- When you pour water into a Brita pitcher, it flows through the filter cartridge.
- The activated carbon traps impurities, and the ion exchange resin replaces unwanted ions with non-mineral ions, such as sodium. This process reduces the mineral content of the water, making it taste better and potentially improving its overall quality.
3. The Result
- The water that emerges from the Brita pitcher is filtered and has a reduced mineral content. This results in water that tastes better, has less chlorine taste and odor, and may be healthier to drink.
4. Replacing the Filter
- It's important to replace the filter cartridge regularly to ensure optimal performance.
- Brita recommends replacing the filter every two months or 40 gallons, whichever comes first.
By understanding how Brita filters work, you can make informed decisions about your water quality and enjoy the benefits of cleaner, better-tasting water.
