The article reviews several shower filters that claim to improve the quality of water for hair and skin, while also discussing their effectiveness in removing chlorine and minerals. Here are some key points:
1. **KDF-55**: Uses copper and zinc alloys to reduce contaminants, including chlorine and metals.
2. **Activated carbon**: Removes a long list of contaminants from water through adsorption, but less effective at removing chlorine in hot water.
3. **Calcium sulfite**: Another chlorine zapper, but not as effective as KDF-55 or activated carbon.
4. **Others**: Various physical filters (for sediment) and vitamin C (another chlorine reducer).
The article also discusses the limitations of shower filters in treating hard water:
* Most filters cannot perform a reduction from hard to soft water due to their small size.
* Small filters, like those in shower filters, cannot hold enough softening resin to remove minerals.
* Shower filters are designed primarily to filter chlorine from water.
In terms of effectiveness, the article tests several models and concludes that:
1. **Aquasana**: Effective at removing chlorine and reducing mineral levels, but has a long effective volume (10,000 gallons) before needing replacement.
2. **Weddell Duo**: Also effective at removing chlorine and reducing mineral levels, with third-party testing verifying its claims.
The article also emphasizes the importance of third-party testing and transparent labeling in determining the effectiveness of shower filters.
Some additional notes:
* The article mentions that some filters claim to "soften" water, but this is not a reality. Water can be softened through softening resin, but most shower filters are not capable of doing so.
* The article quotes experts on the importance of removing chlorine and minerals from water for hair and skin health.
Overall, the article provides a comprehensive review of several shower filter models, highlighting their strengths and limitations, as well as emphasizing the importance of third-party testing and transparent labeling in determining effectiveness.
