The demand for reliable water filtration is rising as concerns about tap water quality—from chlorine and microplastics to PFAS and heavy metals—become more widespread. Consumers are right to be cautious, but not all filters live up to their claims. Clearly Filtered, a US-based company, stands out because its products are independently tested by NSF and IAPMO, two leading certification bodies. The company is currently offering discounts on its entire range, including pitchers, bottles, and under-sink systems.
How Clearly Filtered Works: A Balanced Approach
Unlike some competitors like ZeroWater, which removes nearly all dissolved solids (including beneficial minerals), Clearly Filtered’s filters retain mineral content while targeting harmful contaminants. This results in a more palatable water taste. Independent lab tests (available publicly) confirm the filters effectively reduce chlorine, PFAS, PFOA, and heavy metals. Notably, the company doesn’t just rely on standards with defined testing protocols; they also publish results for hundreds of other contaminants, even if no international standards exist.
The pitcher filter uses activated carbon to remove contaminants while slightly increasing total dissolved solids—a negligible effect, and some even believe activated carbon offers health benefits. It takes roughly 13 minutes to filter half a gallon of water, though the initial priming requires squeezing water through a reusable (but fragile) plastic bag.
Portable and Convenient Options
Clearly Filtered also offers a 32-ounce stainless steel bottle with an integrated filter. This allows on-the-go filtration, though requires moderate suction to draw water through. The system is more socially acceptable than typical backpacking filter straws.
A Renter-Friendly Under-Sink System
The standout product for many will be Clearly Filtered’s under-sink system. Many such filters demand drilling, separate taps, or faucet integration—making them impractical for renters. This system installs inline with existing plumbing in under five minutes, requiring only a wrench to disconnect and reconnect the water line. This is a significant advantage for those who cannot modify their rental units.
The under-sink filter slightly reduces water flow but delivers near-99% PFAS removal and eliminates chloramine (a common disinfectant) to undetectable levels. Priming takes roughly 15–30 minutes of running the tap until dissolved solids return to normal.
The Bottom Line
Clearly Filtered isn’t the cheapest option, but the discounts make its products more accessible. The company’s commitment to independent testing and renter-friendly design sets it apart in a market where skepticism is warranted. While the priming process takes some patience, the benefits of reliably filtered water—without sacrificing taste or convenience—make Clearly Filtered a strong contender for those seeking peace of mind.
