We recommend an indoor relative humidity level of 40-60%. This range is best for creating a comfortable environment, and it is at this level that cold, flu, and other viruses tend to fall apart.

For single room humidifiers, place the unit in the room where humidity is most needed. Whole house humidifiers should be placed in the most centrally-located room of your house. Putting your humidifier next to a cold air return will help spread humidity throughout your home more quickly. Whole house humidifiers should be placed on the bottom floor of multi-level homes.

This depends on the unit. Single room humidifiers can bring the humidity up in a room relatively quickly. Whole house humidifiers typically need 2-3 days to bring your humidity up, especially if it is very dry in your home.

Your 1041 wicking filter is included with the purchase of your humidifier. The optional 1051 air filter is not included, but can be purchased here on our site or at many of our retailers.

You should replace your filter every 60-90 days. Keep in mind that your water may allow for less frequent replacements, or require more frequent replacements. Everyone's water is different and contains different minerals that will affect the life of the wicking filter.

No, the wicking filter is made with a special absorbent paper that will fall apart if you try to wash it.

The “CF” code triggers after 720 hours of use and means it’s time to CHECK your filter. If your filter is still in good shape, simply clear the code by unplugging your unit then plugging it back in. If your filter needs replacing, let your unit dry completely, then replace your filter with a new 1041 Super Wick®.

The “F” code means your unit is empty and needs to be FILLED.

Try adjusting your float.
