Culligan CW-M1 Refrigerator Water Filter, 0.5 Gpm, 300 Gal

This Culligan refrigerator water filter is a direct replacement designed to fit Whirlpool Filter 7 and EDR7D1 models. It uses a compressed carbon block to remove and reduce impurities, sediment, chlorine taste and odor from your drinking water and ice cubes. The filter delivers fresh, clean-tasting water for everyday use—whether for drinking, cooking, coffee or smoothies—without the need for professional installation.

The carbon block contains millions of active sites on its surface and within its structure that work like a sponge to absorb impurities and like a magnet to adsorb and hold other contaminants. The filter can also catalytically break down additional impurities through a process similar to how a catalytic converter works in an automobile.

Features and Benefits

• Multi-stage filtration: Carbon block absorption, adsorption and catalytic breakdown work together to remove sediment, impurities, chlorine taste and odor.
• High capacity: Delivers up to 300 gallons of filtered water before replacement is needed, lasting approximately 6 months of typical use.
• Easy DIY installation: Tool-free replacement fits directly into compatible Whirlpool refrigerator models without professional help.
• NSF certified: Certified against NSF/ANSI standards 42, 53, 372, 401, P473 and CSA B483.1 for contaminant reduction.
• Better water quality: Compressed carbon block design provides tremendous capacity to remove impurities and improve taste.
