Overview
The Pureplus RWF3500A+AF004 is a slim replacement water filter cartridge, about 2 x 2 x 7.7 inches and 1.37 pounds, sold in a three pack with ANSI certification.
The narrow, elongated shape is typical of refrigerator style filter cartridges rather than under-sink or faucet units. Pureplus builds these as compatible replacements, but the listing does not name which original systems it is built to fit, so match the cartridge's dimensions and connector against your current filter before ordering. ANSI certification covers the testing standard the filter media was measured against.
- ANSI certified
- 3 pack of cartridges
- Slim 2 x 2 x 7.7 in size
- 1.37 lb per cartridge listing weight
Who it's for
Fits anyone already using a slim, refrigerator style cartridge filter who needs replacements on a recurring basis. Not the right choice if you cannot confirm this cartridge matches your existing housing.
Strengths and trade-offs
Drawn from this product's published specifications.
- Three pack reduces reorder frequency
- ANSI certified filter media
- Lightweight and compact
- No named compatibility list
- No specific ANSI standard number listed
Performance notes
ANSI certification indicates the filter met a recognized testing standard, though the listing does not specify which contaminant reduction standard applies. The compact 2 x 2 x 7.7 inch size points to a refrigerator or similar slim housing rather than a full under-sink canister.
