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. Context, not marks against it, and our read of the data, not a lab test.
Overview
The Pureplus PP-RWF4700AC uses a combination of coconut shell carbon and polypropylene as its filtration materials. Coconut shell carbon is used for adsorption of chlorine and organic taste-and-odor compounds, while polypropylene is commonly used as a pre-filter layer to capture sediment and particles before they reach the carbon stage. The filter carries ANSI certification and comes in a two-pack.
At $20.24 for two, the per-filter cost is approximately $10.12, placing this among the lower-cost certified options in the replacement filter category. The filter measures 3.5 x 3.5 x 5.7 inches and weighs 1.1 pounds, typical of round push-in cartridges used in certain French door and side-by-side refrigerators.
With 3,030 reviews and a 4.6 average, the PP-RWF4700AC has a substantial review base. A 4.6 at that volume is a reliable indicator of consistent performance and fit across many compatible refrigerators.
Pros
- Coconut shell carbon and polypropylene dual-media construction for taste and sediment reduction
- ANSI certified for independent performance verification
- Two-pack at $20.24 puts per-filter cost at about $10.12
- 3,030 reviews provides a large and reliable satisfaction sample
Cons
- ANSI certification is listed without a specific NSF standard number, limiting detailed contaminant coverage comparisons
- 4.6 average is slightly below top-tier filter competitors
- No gallon capacity or filter-life rating is published in the available data

What buyers say
Over 3,000 reviews at a 4.6 average represents one of the higher review volumes in this product set. Buyers broadly report satisfactory fit and taste improvement, and the volume of feedback makes the rating more statistically reliable than products with fewer than 500 reviews. Minor issues account for the small gap below 4.7 but do not indicate a widespread problem.

Frequently asked questions
What does polypropylene do in a water filter?
Polypropylene (PP) is a synthetic fiber commonly used as a mechanical filtration layer in water filters. It captures sediment, sand, rust, and other particles through physical screening. In a combination filter with carbon, the PP layer typically acts as a pre-filter to prevent large particles from clogging the carbon media, extending the life and effectiveness of the carbon stage.
Is ANSI certification the same as NSF certification?
ANSI (American National Standards Institute) sets the standards framework, while organizations like NSF, IAPMO, and WQA test and certify products against those ANSI standards. A product that is ANSI certified has been tested against one or more ANSI/NSF standards. Products listed as NSF certified have typically been tested by NSF International specifically. Both refer to compliance with the same underlying ANSI standards.
How do I confirm the PP-RWF4700AC fits my refrigerator?
Check your current filter's model number, typically printed on the filter label or housing, and compare it to the RWF4700AC compatibility listing. The filter measures 3.5 x 3.5 x 5.7 inches. Common compatible refrigerators using this form factor include certain Whirlpool and Maytag models that use the 4396710 or 4396841 filter family. Confirm with the manufacturer's compatibility guide before ordering.
