Filter Cotton Sticks for Humidifier | Replacement Wicks for USB Diffusers

Keep your small USB humidifier working at its best with these replacement filter cotton sticks. Designed to fit most portable USB humidifier caps, these wicks help diffuse mist, purify water, and maintain consistent performance. Each stick is made from high-quality filter cotton and can be trimmed to your preferred length.

These filter sticks are a simple and affordable way to extend the life of your mini humidifier. Over time, original wicks can become clogged or worn out, reducing mist output. Replacing them regularly keeps the air fresh and the device running smoothly. The cotton material is low temperature resistant and works well with water-based fragrance oils for gentle aroma diffusion.

Installation takes only a few minutes. Unscrew the tank cap, remove the old filter, and insert a new stick. No tools or special skills are needed. Each pack includes multiple sticks so you always have a spare on hand.

Usage Scenario

Sarah uses her small USB humidifier every night on her nightstand. After a few weeks, she noticed the mist was weaker and the device made a sputtering sound. She remembered the filter stick needed changing. In under two minutes, she unscrewed the cap, replaced the old cotton wick with a fresh one, and screwed the cap back on. That night, the humidifier ran quietly and produced a steady, gentle mist again.
