Boron
Health Canada has proposed a maximum acceptable concentration (MAC) of 2 mg/L (2000 μg/L) for total boron in drinking water based on treatment achievability. Boron-contaminated irrigation water can cause a toxic response to plants grown hydroponically. Recommended boron concentration for commercial plant nutrition is less than 1 ppm.

Grade B Borosilicate Glass Fiber
To some extent, all glass fiber filters have the potential to shed some fibers. Acrylic resin bonded glass fiber filters typically shed much lower amounts of fibers compared to binderless glass fiber filters. The amounts of shed fibers not only depend on the grades of glass fiber media used but are also influenced by the application conditions.
