Cool-mist humidifiers filled straight from the tap.
Each driver rated 0 (none) to 10 (worst)
Evidence strength: moderate · Detox Score = 100 − hazard×4.6 − exposure×3.4 − persistence×2.6, clamped 1–100.
A Detox Score of 64 places ultrasonic humidifier (tap water) in the Low band. None of the three drivers is severe, which keeps the burden manageable. Ultrasonic units aerosolise whatever is in the tank — dissolved minerals become the fine white dust that settles on surfaces, and a standing tank can grow microbial films. Distilled water and routine cleaning address both.
Ultrasonic Humidifier (Tap Water) has a Detox Score of 64 out of 100 (Low burden), which means it is a relatively low-burden choice. Ultrasonic units aerosolise whatever is in the tank — dissolved minerals become the fine white dust that settles on surfaces, and a standing tank can grow microbial films. Distilled water and routine cleaning address both.
A lower-exposure swap for ultrasonic humidifier (tap water) is: Distilled or demineralised water, emptied and cleaned between uses. Ultrasonic units aerosolise whatever is in the tank — dissolved minerals become the fine white dust that settles on surfaces, and a standing tank can grow microbial films. Distilled water and routine cleaning address both.
