Storing
Note: We recommend replacing the cotton bar
every month with consistent use. To purchase
cotton bar replacements, search “USB humidifier
replacement” online. Make sure the bars
purchased are the correct dimensions (see
Figure 4.2). Bars can also be trimmed to fit the
humidifier if they are too long in height. Soak the
cotton bar in purified water for 5 minutes before
installing.
