Every category below is a live Value Score tool — assembled from manufacturer specs and standards-body data, normalized to price, and reweightable by you. We don't name a winner. You set what matters; the math ranks it. The formula is published on every page.
12 units scored on CADR-smoke, coverage, noise & running cost.
Real flow @ 70° rise, UEF efficiency, warranty & recirculation.
Honest running watts (NG), fuel flex, runtime, noise & ATS.
Grain capacity, service flow, salt efficiency & NSF/ANSI 44.
Service flow, media capacity, micron, scope & NSF/WQA cert.
DOE 2019 pint capacity, coverage, ENERGY STAR EF, pump & noise.
First-hour rating, UEF efficiency, capacity, recovery & warranty.
Real DOE-rated BTU, coverage, CEER efficiency, noise & inverter.
Burr type, grind range, retention, consistency & motor.
Boiler type, pressure, PID, steam power & warm-up time.
SCA-cert brew temp, carafe type, capacity & programmability.
Usable capacity, wattage, temp range, presets & footprint.
Suction (Pa), navigation, self-empty, mop & battery.
SEER2/HSPF2 efficiency, BTU, turndown & low-temp heat.
GPH at 10ft head, HP, switch type, backup & build.
Real usable Wh, output watts, chemistry, cycles & recharge.
1. We assemble the data. Every unit's specs pulled from manufacturer sheets and standards bodies (AHAM CADR, DOE UEF, ENERGY STAR) — the numbers nobody else bothers to put in one sortable place.
2. You set the weights. Drag sliders for what your household cares about. The Value Score = weighted, field-normalized spec quality ÷ price. Change a slider, the ranking recomputes live.
3. The formula is public. No black-box "editor's pick." The equation is printed on every category page. The only thing we add is the assembly — and we let you argue with it.
