Buying Guide: How to Choose
Start by getting your water tested to know what contaminants you're dealing with — this determines what filtration technology you need. Activated carbon filters handle chlorine, taste, and odors but don't remove heavy metals. Reverse osmosis (RO) removes up to 99% of contaminants but wastes water. UV filters kill bacteria and viruses. For most tap water concerns, a certified activated carbon filter or RO system covers the bases. Look for NSF/ANSI certifications that confirm what the filter actually removes. Consider filter replacement frequency and ongoing costs when evaluating total value.
Our Verdict
Access to clean, great-tasting water shouldn't be complicated or expensive. The Berkey Big Water Filter System is our top choice for comprehensive filtration without ongoing costs, while the APEC RO-90 offers the most thorough countertop purification. For renters or those wanting a simple solution, the ZeroWater ZP-010 pitcher is a superb starting point. Whatever system you choose, it's an investment in your daily health.
