203 owner reviews, fewer than most models here
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 Icepure RWF3100A is a single-pack replacement filter built with coconut shell activated carbon. It holds certification to NSF/ANSI 42 (aesthetic effects, including chlorine taste and odor reduction) and NSF/ANSI/CAN 372 (lead-free material compliance). Both certifications are issued by recognized independent testing bodies.', 'At $35.59 for a single filter, the price is on the higher side for a one-unit purchase in this category. Buyers looking for per-unit value may find the economics better in a multi-pack, though no multi-pack variant is reflected in this listing.', 'Coconut shell carbon is chosen here for its fine microporous structure, which is effective at adsorbing organic compounds responsible for off-tastes and odors. No capacity or compatible appliance data is available in the current spec set.']
Pros
- Certified to both NSF/ANSI 42 and NSF/ANSI/CAN 372
- Coconut shell carbon media is a well-regarded choice for taste and odor reduction
- Lead-free material certification (CAN 372) adds a material safety layer
- 4.4 stars from 203 reviews indicates generally positive buyer experience
Cons
- Single-pack pricing at $35.59 is relatively high for one unit
- No filter capacity or lifespan rating available
- No compatible appliance list in published specs

Performance notes
The RWF3100A is certified to NSF/ANSI 42, which covers aesthetic effects such as chlorine taste and odor reduction. It also carries NSF/ANSI/CAN 372 certification, confirming lead-free material composition. These certifications do not extend to health-effects contaminants such as lead ion reduction unless separately certified under NSF/ANSI 53. No capacity rating is stated, so replacement schedule should follow appliance manufacturer guidelines.
What buyers say
At 4.4 stars from 203 reviews, buyer response is positive without being exceptional. The review count is modest but sufficient to indicate consistent performance across a variety of installations. No major fit or flow concerns are apparent from the aggregate score.

Frequently asked questions
What does NSF/ANSI/CAN 372 certification cover?
NSF/ANSI/CAN 372 is a certification specifically focused on lead-free compliance in plumbing products. It verifies that the materials used in the filter construction meet the lead content thresholds required by U.S. and Canadian standards. This is a material safety certification, not a performance claim about lead reduction in filtered water.
Is the RWF3100A a direct replacement for OEM refrigerator filters?
Icepure designs its filters to be compatible with specific OEM filter models, and the RWF3100A model number corresponds to a particular appliance line. However, no compatible appliance data is confirmed in the current spec listing. Check Icepure's compatibility guide or the product page to match your refrigerator model before purchasing.
Why does coconut shell carbon matter in a water filter?
Coconut shell activated carbon has a higher surface area per gram compared to coal-based activated carbon, giving it more sites to adsorb organic compounds, chlorine, and taste-affecting chemicals. It is a common premium material choice in certified water filters. The actual filtration outcome depends on the full filter design, contact time, and water quality, not just the carbon source.
