Product review (1 stars): False Information - Not NSF/ANSI 53 Certified!
I ordered this based upon the product description which represents that:
"All components NSF-42/53 certified.  The Activated Carbon Block Filter inside has NSF42/53 approval." Being leery of these claims I also searched the reviews for "53" to see if in fact this was true.

After reading a review by a reviewer posted on 3/12/15 "No Worries" I went ahead an purchased. The filter (i.e. model RFC0600A) and packaging that I received looks just like the one in the photo and includes a product specifications/data sheet. I was just about to install the filter and decided to check for the NSF 53 certification again just to make sure before opening the protective plastic wrapping. The specification sheet however does not support the claim of NSF 53 certification. Nowhere on the box or spec does it say NSF 53 certified. Although it does say NSF 42 (i.e. Aesthetic Effects... taste of the filtered water) and NSF 372 (i.e. which filters lead content)............ the NSF 53 certification, you know the one that filters out contaminants that will affect your health:
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) NOT SO.

But don't take my word on it. Check for yourself. Go to the -Water Quality Association- website and search for this model and you will find the same certifications that are on the product specification sheet (i.e. NSF/ANSI 42 & 372) but it will not list NSF/ANSI 53. You can also check NSF-org.

BUT WAIT... There's More...!!  Go to One Purify's website ShopOnePurity and you'll find that there is no contact information other than an email hmm... -SUSPICIOUS-? No storefront, warehouse, office address, phone number to contact. I suspect that is because "One Purity"/"Ice Pure" are just shell companies for "Tianjin Jinghai Yunda Industry and Trade Co., Ltd." yes, a CHINESE company and we all know about their standards/ethics, which is the name listed on WQA's website for that particular product model number.

If you're only concerned about how your water taste, then save your money and buy it. HOWEVER, If you're concerned about you health and the health of your friends, family and pets DON'T BUY! This is blatant false advertising!

Don't believe the product description. Take the reviewer's comments with a grain of salt. Do check the WQA (water quality association website) and NSF (national science foundation organization website)... for yourself and save yourself the time/money/headache.

Water is LIFE.

I will add a photo of the product specification sheet when I get a chance.
