Fits, works, but only filters for taste and odor
on April 10, 2018
The filter fits and works OK. However, upon further investigation, I find these filters are certified to NSF 42 standards only, rather then also testing to NSF 53. What's the difference you ask?
From the NSF: The commonly tested chemical reduction claims for products seeking certification to NSF/ANSI Standard 42 are: chlorine (taste and odor), chloramines, iron, manganese, hydrogen sulfide, pH neutralization and zinc reduction.
What this means is that NSF 42 is primarily concerned with taste and smell.
Again from NSF: The commonly tested chemical reduction claims for products seeking certification to NSF/ANSI Standard 53 are: heavy metals (arsenic, cadmium, chromium, copper, lead, mercury and selenium), inorganics (fluoride and nitrate plus nitrite) and volatile organic chemicals (chloroform surrogate as well as individual organic chemicals).
What this means is that NSF 53 is primarily concerned with potential health hazards.
I didn't know/realize this, but now I do. I will not be purchasing these filters again.
