Best Performance
Top scorecard finisher (tie), excellent contaminant removal
Average Finish: 1.3
Purchased for: $270
Made In: China
Countertop RO (no plumbing hookup) with very fine membrane rating claimed in video. Very fast for RO and produced very low copper and near-zero fluoride on test strips. Tied for best overall average finish in the scorecard (as stated).
Fast for RO, near-zero fluoride, and extremely low copper in this test.
Best Value
Strong results without the premium price
Purchased for: $34
Made In: Mexico (assembled) with imported components
10 cup, 5-stage system (as described) and includes a TDS meter. Very strong contaminant removal and excellent clarity; tends to strip water heavily, so filter replacements may be more frequent.
Excellent clarity and contaminant reduction for a ~$34 pitcher system.
Runner-up
Gold-standard purification (but slow)
Average Finish: 1.3
Purchased for: $300
Countertop distiller (boils/condenses). Very slow per batch (hours per gallon, and ~41 min for 2 cups in the video) and uses significant electricity (~575W noted), but produced very low copper and zero fluoride on test strips. Tied for best overall average finish in the scorecard (as stated).
Very clean output, but filtration speed is the tradeoff.
Prices are the approximate prices stated in the video at the time of testing. (Links intentionally omitted.)
Copper-spiked water was filtered and measured using a dedicated copper tester (some results were below 0.1 ppm; two filters exceeded the tester’s 5 ppm range, shown here as 5.5 to indicate “over max”).
Measured time to filter two cups of water. LifeStraw and distillation were dramatically slower than pitcher filters; the countertop RO unit was among the fastest for high-performance purification.
Dirty pond water was mixed with red food coloring and then filtered. The color score is from the video’s dye/color measurement method (lower is better). Several systems scored a perfect 0.00.
Fluoride levels were estimated using color-matching test strips after intentionally saturating the test water with fluoride. Values are approximate (strip-based), but relative performance was clearly distinguishable in the video.
TDS readings from the dirty pond-water + dye test segment. Note: TDS alone does not equal “unsafe” (as noted in the video), and some systems required conditioning with tap water which can affect readings.
