FAQ

Q1: What is a humidifier wick filter?

A: In an evaporative humidifier, the wick draws water up for the fan to evaporate and traps minerals so they stay out of the air.

Q2: When should I replace the wick?

A: Replace it when output drops or the wick becomes clogged with minerals — usually every few weeks to months.

Q3: Why does the wick matter?

A: Its surface area sets output, and its filtration keeps minerals from becoming airborne white dust.
