How these scores are built
- Clean air — normalized 1 to 10 from cadrSmoke (CADR), the same field for every model.
- Quiet — normalized 1 to 10 from noiseDbMin (dB), the same field for every model.
- Smart — normalized 1 to 10 from features, the same field for every model.
The overall column is the weighted mean of those dimensions, so a model cannot buy its way up the table. Prices are typical street prices on Amazon and move; check the current one before deciding. Amazon links are affiliate links (tag: habilytics-20) at no extra cost to you.
