Those two materials can significantly affect the quality of high-flow filter cartridges. Some manufacturers adopt bad and cheap plastics, which are often recycled plastic and not 100% pure polypropylene. This type of plastic not only harms the environment but also human health.

Brother Filtration only utilizes pure polypropylene, which conforms to the FDA and CE standards. That means, the polypropylene we use, can directly contact with food, which is safe enough for the food & beverage industry.
