40 Pack Humidifier Cotton Filter Refill Stick Portable

$5.99

Updated 2026-11-03

This listing is a 40-pack of cotton filter refill sticks designed for portable humidifiers. Each stick measures 4 in in length, a compact format suited to small personal units rather than large console models. The cotton material is intended to draw water upward through capillary action, where it can be released as moisture. Keeping a multi-pack on hand supports a steady replacement routine.

Because humidifier wicks collect mineral deposits over time, they tend to stiffen and lose absorbency with use. Replacing the stick periodically helps the unit continue dispersing moisture evenly. The 4 in size keeps the refill lightweight and easy to swap, and the cotton construction is simple to handle during changes. These sticks are intended for compatible portable humidifiers only.

With 40 pieces in the pack, the supply is aimed at households that run a humidifier frequently or maintain more than one small unit. Storing the extras in a dry place keeps them ready for the next change. Before ordering, confirm that the humidifier accepts a 4 in cotton filter stick, since fit varies between models and brands.
