What to know before buying

The filter is stated to fit standard faucets only. The listing excludes pull-out, handheld, spray-style and sensor faucets, so confirm the tap type before buying. It says only the WD-CFF-03 filter is supported. The listed maximum TDS of 1000 is not evidence of TDS reduction. The stated 4,000-gallon capacity and six-month life are manufacturer claims, not independently verified performance.
