Top 4 Amazon Water Filters of 2025

The iSpring RCC7 delivers exceptional filtration, great taste, and solid value. Its 5-stage filtration system removed 100% of all six contaminants in our tests—an unmatched performance. Testers described the water as neutral, crisp, and odorless. While its $50 annual filter cost isn’t the cheapest, it’s still $10–$100 more affordable per year than other high-performing models. Though not the lowest-priced under-sink filter, it outperforms budget options like the APEC WFS-1000 in contaminant removal, making it a high-value reverse osmosis choice.

Installation is similar to other reverse osmosis systems, typically taking a few hours for a DIY setup. However, the stage 1-3 filters require replacement every six months, more often than long-lasting options like the Bluevua RO100ROPOT—though Bluevua costs significantly more. If you prefer a lower-maintenance alternative, the APEC WFS-1000 is easier to manage and more budget-friendly.

The ZeroWater 10-Cup 5-Stage Filter excels at removing contaminants, including PFOA/PFOS, and comes with a total dissolved solids (TDS) meter for monitoring water purity. Its quick setup and convenient pour spout make it an easy-to-use option for individuals or small families seeking top-tier filtration.

However, not all testers enjoyed its light, neutral taste, which some found less appealing than the PUR Classic 11-Cup Pitcher. Additionally, its higher filter cost results in a greater annual expense compared to other models, though it outperforms many in contaminant removal.

The APEC WFS-1000 is a cost-effective and reliable water filter, ideal for those seeking cleaner, better-tasting water. Its compact, tankless design fits well in small under-sink spaces, and its simplified setup makes installation more accessible. In our tests, it effectively removed chlorine, fluoride, copper, and lead, resulting in great-tasting water at an affordable price.

However, the WFS-1000 struggled to filter high levels of sulfates and iron, making it less suitable for areas with sulfur-heavy or metallic-tasting water. Additionally, no PFAS removal data was available. For those needing stronger filtration, the APEC Essence ROES-50 offers reverse osmosis purification, removing iron, sulfates, and other contaminants while delivering clean, neutral water at a low annual cost.

The PUR Classic 11-Cup Pitcher stands out for its great-tasting water and effective filtration. Its design allows users to pour filtered water while the upper compartment continues filtering, making it a convenient choice for households. Our test team praised its neutral, fresh taste, which closely resembled bottled water, making it an excellent option for those who prioritize flavor and quality.

However, its shorter filter lifespan means more frequent replacements, adding a bit of inconvenience and increasing annual costs. Additionally, no PFAS removal data was available. For those seeking longer-lasting filtration, the ZeroWater 10-Cup 5-Stage is a strong alternative. While ZeroWater filters cost more, they remove more contaminants, though PUR performed better in taste tests.
