Buying Guide
First, check for official NSF certifications to ensure the filter effectively removes the specific contaminants you are concerned about, such as lead (NSF 53).
Compare the long-term cost of replacement filters, not just the initial unit price. Finally, always double-check that the filter is compatible with your specific model of sink faucet before purchasing.
What is a Sink Faucet Filter?
A sink faucet filter is a point-of-use water purification device that attaches directly to the threaded end of your kitchen faucet. Inside the unit is a replaceable filter cartridge containing filtration media like activated carbon. When you engage the filter, tap water is forced through this cartridge, which captures and reduces impurities. A diverter switch on the unit allows you to easily toggle between the filtered water stream and your regular, unfiltered tap water, preserving the filter’s life for drinking and cooking purposes.
Helpful Information
Installation and Usage
Installation:
- Remove the Aerator: Unscrew the existing aerator from the tip of your faucet.
- Find the Adapter: Your filter kit will include several adapters. Find the one that matches the threads on your faucet.
- Attach the Filter: Screw the adapter onto the faucet, then screw the filter’s mounting collar onto the adapter until it is snug.
Usage:
All models have a diverter switch. Flip it one way for regular tap water (for washing dishes) and the other way for slow-flowing, filtered water (for drinking and cooking).
Tips
- Don’t Use Hot Water: Never run hot water through a faucet filter. The heat can damage the filtration media, making it ineffective and potentially releasing trapped contaminants.
- Subscribe and Save: Many brands and online retailers offer a subscription service for replacement filters. This is a convenient way to save money and ensure you always have a new filter on hand when you need it.
- Flush New Filters: When you install a new filter cartridge, it’s important to run cold water through it for 5-10 minutes. This flushes out any loose carbon particles and activates the filter.
- Dealing with Low Pressure: A faucet filter will naturally reduce your water flow rate. If the pressure seems excessively low, first check that the filter cartridge is not clogged and is installed correctly.

FAQ
Q: Why does water from a new filter run black at first?
A: This is completely normal. The black particles are harmless activated carbon dust from the filter cartridge. Flushing the new filter with cold water for 5-10 minutes as instructed will clear this dust out before you start drinking the water.
Q: Are countertop filters better than faucet-mount filters?
A: Countertop filters like the Apex model generally offer more comprehensive filtration and a much longer filter life because their larger size can accommodate more advanced, multi-stage filter media. However, they take up counter space. Faucet-mount filters are more compact and convenient, though their filters need to be changed more frequently.
Q: Can a faucet filter increase my water pressure?
A: No, a faucet filter will always decrease your water pressure to some extent, because the water has to pass through the dense filtration media. If your home already has very low water pressure, a faucet filter might result in a very slow flow of filtered water.
Conclusion
A high-quality filter for your sink faucet is an incredibly simple, convenient, and effective way to ensure you have clean and safe drinking water on demand.
By immediately improving the taste and reducing harmful contaminants, these devices offer daily peace of mind and are a smart, sustainable alternative to bottled water.
