Is Humidifier HSA-Eligible? (2026)

Humidifiers are HSA-eligible only with a letter of medical necessity for a respiratory or skin condition.

Typical Cost

$30–$200

Details

Same story as air purifiers. A humidifier for general comfort doesn't qualify. But if your doctor prescribes one for a condition like chronic sinusitis, eczema, croup in children, or a respiratory illness, it becomes eligible. Get the letter of medical necessity before you buy, not after.

Requirements

Requires a letter of medical necessity for a diagnosed medical condition.
