- Compatibility: Pick a filter that fits your under sink system. Check the model number to ensure it matches your setup. This saves time and avoids extra parts.
- Filtration Capacity: Look for filters that remove key contaminants like lead, chlorine, and PFAS. Test your water to see what you need the most. Better filtration means safer water at home.
- Certifications: Choose filters with NSF or ANSI stamps. These show the filter meets safety standards. Trusted brands often have these marks for peace of mind.
- Lifespan: Think about how long the filter lasts before you need to swap it. Most go for 6 months to 1 year or thousands of gallons. Plan for easy access to replacements.
- Price: Compare costs per filter and how often you replace it. Cheaper options may not last as long. Look for deals that fit your budget without cutting quality.
- Ease of Replacement: Find filters that click in fast without tools. Twist-and-lock designs save minutes. This makes upkeep simple for anyone.
