Is the Epic Pure XP worth buying if PFAS, fluoride, or lead removal is your actual goal? That depends almost entirely on a distinction Epic’s marketing hopes you won’t notice. The Pure XP launched February 11, 2026 with strong claims and a compelling sustainability angle, but what it’s certified to do and what it’s merely … Read more
Best shower filter for chloramine is one of the most searched phrases in shower filtration, and (by no surprise) the most misleading. Every product you see marketed as a “chloramine shower filter” is selling you a promise that no manufacturer has independently proven. Not one shower filter on the market holds third-party certification for chloramine … Read more
Do water filters remove nitrates? The answer to this question depends almost entirely on which filter you have. Reverse osmosis, ion exchange, and distillation can remove nitrates.

Do ZeroWater filters remove PFAS and fluoride? Yes, both, and often near-completely. But whether your specific filter is certified to do so is a separate question, and the answer depends almost entirely on which version you’re buying. The brand went through a significant overhaul in 2025, and the gap between the old product and the … Read more
ZeroWater wins if you care most about fluoride removal and broad contaminant coverage on a budget. MaxClear makes more sense for longer filter life and mineral retention, but the devil is in the details. If you’ve been shopping for a water filter that tackles PFAS; the so-called “forever chemicals” now regulated by the EPA, you’ve … Read more
