Cheap filtration is the highest-value corner of this site — a $10 faucet filter genuinely improves chlorine taste, and filtered shower heads are the viral hair-and-skin upgrade of the last two years. It's also the corner with the most overselling, so here's our line up front: these filters improve taste, smell, sediment and chlorine; they are not certified lead-removal or purification systems, and a TDS number is not a safety score. What they actually do, they do well and absurdly cheaply. Each card states the limit alongside the benefit.

If your water is hard or heavily chlorinated, users consistently report less dryness and irritation within a few weeks. The cartridge is the catch — it exhausts in 2–3 months and needs replacing for the effect to last.
Total dissolved solids — a rough mineral-content number, useful for tracking filter performance and comparing sources. It does not detect bacteria, lead or chemicals; a low TDS is not proof of safe water.
Generally no — big brands carry NSF/ANSI certifications, budget listings rarely do. For taste and chlorine that mostly doesn't matter; for health-critical filtration (lead, well water), buy certified equipment instead. We say this on every relevant card.
A TDS meter reads total dissolved solids in ppm — here's the range table (0–50, 50–300, 300–500, 500+), what it does and doesn't tell you about safety, and how to use one properly.
