This Instapure-made compatible filter is the cost-effective USA-made replacement for the GE MWF and Kenmore 46-9991 refrigerator water filter cartridges. The IAPMO R&T certifications against NSF/ANSI 42, 53, 372, 401, P473, and CSA B483.1 standards mean this cartridge is independently tested for reduction of pharmaceuticals, BPA, PFOA/PFOS, chlorine taste and odor, and other contaminants — significantly more comprehensive than basic chlorine-only cartridges.
Compatible fitment with GE MWF and Kenmore 46-9991 housings (the standard refrigerator filter design used across millions of refrigerators) means installation is identical to the OEM cartridge — twist off old, twist in new. The Instapure construction uses ULTRA filtration that handles the modern contaminant profile (pharmaceutical residues, PFAS compounds, microplastics) that older carbon-only filters didn’t address.
Provides great-tasting water and ice for up to six months or 300 gallons — the standard residential filter replacement cycle. Made in Hayward, California by Instapure. For households with GE or Kenmore refrigerators and tired of paying full OEM cartridge prices, this is the right USA-made alternative.
