NSF 53 certified water filters meet the minimum safety requirements to reduce specific harmful water contaminants including:
- Volatile Organic Compounds (VOCs)
- Methyl Tertiary Butyl Ether (MTBE)
The NSF 53 safety standard includes the structural integrity, material safety, and the contaminate reduction performance claims. It typically relates to water filters that use carbon absorption as a means of filtration. The removal rate of water filters that meet this standard can vary. The NSF standard means that the water filter meets a minimum threshold.
