The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other water filtration: replacement filters, under-sink and reverse osmosis systems, filter pitchers, water dispensers, coolers, faucet filters and softeners we track in this category on price, popularity and size.

Overview
At $29.99 for three filters, the RWF4200A costs about $10 per filter. NSF 42 certification specifically covers reduction of aesthetic impurities, including chlorine taste and odor, which is the most common reason households use refrigerator replacement filters. The material listed is a combination of coconut shell carbon and polypropylene, both standard in refrigerator filter construction.
The 2 x 2 x 6-inch compact dimensions fit many common under-shelf or in-door refrigerator filter locations. At 15,200 ratings with a 4.6-star average, this is one of the most widely purchased Pureplus filters and carries a review volume that reflects real-world use across a broad population of buyers.
NSF 42 is specifically for aesthetic impurities and does not extend to health effects contaminants. Buyers who need a filter certified to NSF 53 or higher should check for alternative products.

Performance notes
The RWF4200A is certified to NSF 42, which is specifically for reducing aesthetic impurities such as chlorine taste and odor. It is not listed as NSF 53 certified, so it has not been independently verified to reduce health effects contaminants such as cysts, lead, or VOCs under that standard. The filter uses coconut shell carbon and polypropylene. Dimensions are 2 x 2 x 6 inches. No filter life or capacity figure is provided in the available data.
What buyers say
The RWF4200A has 15,200 ratings at 4.6 stars, which is a very large sample. A 4.6-star average across that many buyers is a reliable indicator of consistent, widespread satisfaction. The slight step below 4.7 or 4.8 star alternatives in the category is marginal and likely reflects the normal variance expected across a large and diverse buyer population.

Frequently asked questions
What does NSF 42 certification mean for the Pureplus RWF4200A?
NSF 42 certification means the filter has been independently tested and verified to reduce aesthetic impurities in drinking water, with chlorine taste and odor being the primary focus. NSF 42 does not cover health effects contaminants such as lead, cysts, or volatile organic compounds. If you need a filter certified to reduce health effects contaminants, look for NSF 53 certification. The RWF4200A is not listed as NSF 53 certified in the available data.
How much does each filter cost in the 3-pack?
The RWF4200A 3-pack is priced at $29.99, which works out to roughly $10 per filter. At a six-month replacement interval, the 3-pack covers approximately 18 months of use for a single refrigerator, making the annual cost of ownership around $20. Actual replacement timing varies with household water usage and water quality.
What materials make up the RWF4200A?
The RWF4200A uses coconut shell activated carbon and polypropylene. Coconut shell carbon is a natural and widely used filtration medium effective for reducing chlorine taste and odor. Polypropylene is a food-grade plastic commonly used in filter housing and structural components. Both materials are standard in NSF 42 certified refrigerator replacement filters.
