IMPORTANT INFORMATION and FEATURES

Your Recirculating Console Humidifier is an 

EVAPORATIVE TYPE  

HUMIDIFIER

. This means that the air being drawn through the 

moistened filter naturally evaporates the water and disperses

  

INVISIBLE  MOISTURE

  into  the  air.  This  type  of  humidifier 

DOES NOT PRODUCE MIST, WATER DROPLETS, STEAM OR 

EXCESSIVE CONDENSATION

 associated with other types of 

humidifiers.

EXCESSIVE  HUMIDITY  CAN  OFTEN  LEAD  TO  UNANTICI-

PATED PROBLEMS

. Air containing water droplets or mist can 

create a good habitat for the growth of mold and mildew.

Misting units often oversaturate the air, while the Lasko Recirculating 

Console Humidifier reaches a maximum humidity output level 

without oversaturating. With a properly operating Evaporative  

Humidifier, the evaporation rate increases naturally when the 

air is dry. When the humidity in your home is high, moisture 

output  automatically  decreases  to  help  prevent  damaging 

condensation.

The Watershow Viewing Window provides a visible way for you 

to know that your Recirculating Console Humidifier is operating. 

As air passes over the filter, the humidity in the room will in-

crease, and the water level in the Unit will begin to decrease.

Unlike misting humidifiers, the Evaporative Filter in your Recirculat-

ing Console Humidifier also traps unwanted minerals that reside 

in normal tap water. This filtering also assures there is 

NO WHITE 

DUST

 dispersed into the air.

NOTE:

 

A few droplets of water may be present in your hu-

midifier as a result of our quality testing prior to packaging 

and shipment.

When using electrical appliances, especially where children are 

present, basic precautions should always be followed in order 

to reduce the risk of fire, electric shock and injury to persons.  

Including the following:

1.

  To prevent possible electrical shock, always turn the unit  

off and unplug before filling, servicing or moving.

2.

  Always place Humidifier on a stable, flat, level surface. Lo-

cate Power Cord so the Humidifier or other objects are not 

resting on it. Keep the Cord away from room traffic.

3.

  Do not place Humidifier near a heat source such as stoves,  

radiators or heaters.

4.

  This appliance is equipped with a polarized plug (one blade is 

wider than the other). To reduce the risk of electrical shock, this 

plug is designed to fit in a polarized outlet only one way. If plug 

does not fit, contact a qualified electrician. Do not attempt to  

defeat this safety feature.

WARNING: THIS PLUG IS A SAFETY FEATURE. TO REDUCE

THE RISK OF FIRE, ELECTRIC SHOCK AND PERSONAL IN

JURY, DO NOT REMOVE, REPLACE, REPAIR OR TAMPER 

WITH THE ORIGINALLY SUPPLIED PLUG. IF THE FAN 

DOES NOT FUNCTION PROPERLY, IT MAY BE DUE TO THE 

SAFETY DEVICE INCORPORATED IN THIS PLUG. RETURN TO 

IMPORTANT SAFETY INSTRUCTIONS

DO NOT pour water into Grill. DO NOT spill water on Control Panel.  

Water should only be poured into the Unit using the Jug.

5.  Never tilt or attempt to move the Humidifier while it is operating.

6.  Always direct air flow away from walls or furniture as excessive 

moisture may cause damage.

7.  Humidifiers require regular cleaning to maintain proper oper-

ating conditions. Refer to Cleaning Instructions for proper cleaning  

procedures.
