Frequently asked questions
What does NSF 42 certification mean for the Pureplus RWF4700AC?
NSF 42 certification means the filter has been tested and certified to reduce aesthetic impurities, most commonly chlorine taste and odor. It does not cover health-effects contaminants like lead or certain chemicals. For those, you would need a filter also certified to NSF 53 or NSF 401.
Is coconut shell carbon better than other carbon types?
Coconut shell activated carbon is widely used in water filters because it has a high surface area, which gives it good adsorption capacity for chlorine, odor, and some organic compounds. Whether it is better than other carbon types depends on the specific contaminants you are trying to reduce. For chlorine taste and odor, it performs well.
How do I know if the RWF4700AC fits my refrigerator?
Cross-reference the RWF4700AC model number with your refrigerator's owner manual or the filter part number listed on your current filter. The 1.9 x 1.9 x 6.6 inch dimensions can also help you compare against your existing filter size. When in doubt, check the Pureplus compatibility list before purchasing.
