Performance notes
Certified to ANSI standards. The ANSI designation covers testing protocols for materials and performance but the specific reduction claims depend on the test scope applied. No purification method beyond the implied activated carbon media is stated. Without a published gallon capacity, replacement scheduling should follow manufacturer refrigerator guidance, typically every six months.
What buyers say
Over 3,000 reviews at 4.7 stars reflects a consistently positive reception. Buyers at this volume and rating typically report reliable fit, acceptable taste improvement and straightforward installation. The high review count reduces the likelihood of outlier variance skewing the rating.

Frequently asked questions
What certification does the Pureplus RWF3500A+AF004 carry?
This filter is certified to ANSI standards. ANSI (American National Standards Institute) certification indicates the product has been tested against defined performance benchmarks. For context, NSF International also uses ANSI standards as the basis for many of its water filter tests, so ANSI certification is a meaningful baseline indicator.
How long does the Pureplus RWF3500A+AF004 filter last?
Pureplus does not publish a specific gallon-life figure for this model. Most refrigerator replacement filters are designed to last six months under typical household use. If you use more water or have sediment-heavy supply, consider replacing it sooner. Your refrigerator's filter indicator light is also a reliable replacement trigger.
