IMPORTANT SAFETY INSTRUCTIONS

READ AND SAVE THESE INSTRUCTIONS

IMPORTANT INFORMATION 

and FEA

TURES

Your Recirculating 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 UNANTICIPATED 

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  Humidifier reaches a maximum humidity output level 

without oversaturating the air. 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 automati-

cally decreases to help prevent damaging condensation.
The Watershow Viewing Window provides a visible way for you to 

know that your Recirculating Humidifier is operating. As air passes 

through the filter, the humidity in the room will increase, and the 

water level in the Unit will begin to decrease.
Unlike misting humidifiers, the Evaporative Filter in your   

Recirculating 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 humidifier 

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. Locate 

Power Cord so the Humidifier or other objects are not resting on 

it. Keep the Cord away from room traffic.

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.

Rev. C 5/12 

2084400

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 prong 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.

5.

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

6.

 Always direct air flow away from walls or furniture. Excessive 

moisture may cause damage.

7.

 Humidifiers require regular cleaning to maintain proper operat-

ing conditions. Refer to 

CLEANING

 

section for proper cleaning 

procedures.
