377 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 RWF4700AC ships as a 4-pack at $33.99, putting the per-cartridge cost at about $8.50, which is competitive for this filter format. The filter uses carbon fiber media rather than the granular activated carbon found in many competing alternatives. Carbon fiber-based media has a higher surface area density compared to granular forms, which may improve contact time with water passing through the filter.
The certifications are NSF/ANSI 42 for reducing aesthetic impurities and NSF/ANSI/CAN 372 for lead-free material compliance. These cover taste and odor improvement and confirm the housing materials are lead-free. No NSF 53 or health-effect certification is listed. The RWF4700AC format is compatible with a range of Samsung and other refrigerator brands depending on the specific model.
At 377 reviews with a 4.6-star average, buyer sentiment is positive but the review base is smaller than the most widely reviewed RWF4700AC alternatives. This listing appears to be a newer or lower-visibility variant of Icepure's RWF4700AC line.
Pros
- Certified to NSF/ANSI 42 and NSF/ANSI/CAN 372
- Carbon fiber media may offer higher surface area than granular activated carbon
- 4-pack at $33.99 is roughly $8.50 per cartridge
- 4.6-star average from buyers
- Lead-free construction confirmed by NSF 372 certification
Cons
- No NSF 53 certification for health-effect contaminants such as lead
- 377 reviews is a moderate sample, smaller than top-volume RWF4700AC competitors
- No dimensions listed, making physical fitment harder to pre-verify
- No rated capacity or service life

Performance notes
The Icepure RWF4700AC uses carbon fiber media and carries NSF/ANSI 42 certification, which covers reduction of aesthetic impurities including chlorine taste and odor. NSF/ANSI/CAN 372 certification confirms lead-free materials in the filter construction. No NSF 53 or NSF 401 certification is present. The filter weighs 1.9 lb for the 4-pack. No dimensions, flow rate, or gallon capacity data was available in the listing.
What buyers say
377 reviews averaging 4.6 stars reflects a broadly satisfied buyer base, though the review count is on the lower end for a widely-sold filter format like the RWF4700AC. At this volume, real installation and performance data is meaningful but conclusions carry more uncertainty than products with several thousand reviews. No bought-last-month data was available.

Frequently asked questions
What is the difference between carbon fiber and activated carbon media in refrigerator filters?
Standard activated carbon in refrigerator filters typically uses granular or block forms of processed carbon with high surface area for adsorbing chlorine compounds and aesthetic impurities. Carbon fiber media uses carbon in a fibrous form, which can offer a higher surface area per unit volume and more consistent flow paths compared to granular packing. Both types work through adsorption to reduce chlorine taste and odor, but carbon fiber is less common in the aftermarket refrigerator filter category.
What refrigerators is the RWF4700AC format compatible with?
The RWF4700AC filter format is designed for certain Samsung and other brand refrigerators. Samsung models that originally used the RWF4700AC or the DA97-17376B filter are common targets for this format. Always verify the compatibility list on the product page against your specific refrigerator model number before purchasing, as multiple similar filter formats exist for Samsung refrigerators.
Does this filter reduce lead?
The Icepure RWF4700AC carries NSF 372 certification, which confirms the filter materials are lead-free, meaning the filter itself does not introduce lead into water. However, it does not carry NSF 53 certification, which is the standard for lead reduction from incoming water. If your concern is lead in your household water supply, a filter certified to NSF 53 specifically for lead is the appropriate choice.
