 AIR FILTER 

The AIRCARE

®

 filter  #1051 is an excellent means of cleaning the air while using 

your humidifier. The first stage of the air filter is a high-efficiency, electrostatically 

charged filter media which traps dust, pollen, and airborne pollutants. The second 

stage is an activated carbon media which absorbs odors from cooking, pets, or 

tobacco smoke.  

We recommend replacing the AIRCARE

®

 air filter at least once a year and more 

often if necessary.  When the white filter media is coated with a layer of dust and 

dirt, it is time to replace the air filter.  The certified water output of your humidifier 

will be reduced when using the air filter.  The air filters are optional and are not 

required for normal operation of the humidifier. The 1051 is available for purchase 

by calling 1-800-547-3888. 

CARE AND MAINTENANCE 

CAUTION: Disconnect power before filling, cleaning or servicing unit. Keep grille 

dry at all times.

Cleaning your humidifier regularly helps eliminate odors and bacterial and fungal 

growth.  Ordinary household bleach is a good disinfectant and can be used to wipe 

out the humidifier base and bottle/reservoir after cleaning.  We recommend 

cleaning your humidifier at least once every two weeks to maintain optimum 

environmental conditions for your home. 

We also recommend using AIRCARE

®

 or Essick Air

®

 Bacteriostat Treatment each 

time you refill your humidifier to eliminate bacterial growth.  Add bacteriostat 

according to the instructions on the bottle.  Please call 1-800-547-3888 to order 

Bacteriostat Treatment reference part number 1970.   

1.  Turn off unit completely and unplug from outlet. 

2.  Lift out the water bottles and the power pack.

or any other cleaners on the wick.  Leave in sink to drain.
