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 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
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 increase, and
the water level in the Unit will begin to decrease.
Unlike misting humidifiers, the Evaporative Filter in your Recirculating
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 humidifier as a result of our quality testing
prior to packaging and shipment.

When using electrical appliances, basic precautions should always
be followed to reduce the risk of fire, electric shock and injury to
persons, including the following:
1. Make certain that the power source conforms to the electrical
requirements of the Humidifier.
2. Where possible, avoid the use of extension cords. If you must
use an extension cord, minimize the risk of overheating by using the shortest cord possible and ensuring that it is UL Listed.
NEVER use a single extension cord to operate more than one
appliance
3. Do not insert fingers or foreign objects into the Humidifier. Do not
block or tamper with the Humidifier in any manner while it is in
operation. NEVER tilt or attempt to move the Humidifier while it is
operating.
4. Always unplug the Humidifier before filling, servicing or moving
the Humidifier.
WARNING: DO NOT DEPEND ON THE ON/OFF KNOB AS THE
SOLE MEANS OF DISCONNECTING POWER WHEN FILLING,
SERVICING or MOVING THE HUMIDIFIER. ALWAYS UNLPUG
THE POWER CORD.
5. This Humidifier is intended for general use only. It must NOT
be used in potentially dangerous locations such as flammable,
explosive, chemical-laden or wet atmospheres.
WARNING: REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK DO NOT USE THIS HUMIDIFIER WITH ANY SOLID STATE SPEED
CONTROL DEVICES.
6. Always place the humidifier on a stable, flat level surface when
operating, to avoid the risk of the Humidifier overturning. Locate
the power cord so the Humidifier or other objects are not resting
on it. Keep the power cord away from room traffic.
7. Do not place Humidifier near a heat source such as stoves,
radiators or heaters.

FILLING and OPERATION
CAUTION: Do not pour water through
the Exhaust Grill on the Upper Housing.
Doing so may cause damage and personal
injury.
CAUTION: • Unplug Unit when filling.
• Always place Humidifier on a firm level surface.
Locate the Power Cord so the Humidifier is
not resting on it, and is away from traffic.
• Be careful not to overfill.
3 -For fast humidification of a large room or house,
approximately 9 gallon per day.*
2 -For normal operation.
1 -For quiet, night time operation or after desired moisture
level is reached.
The Filter inside your Humidifier plays a very important part in
its operation. In order to maintain peak performance, it is highly
recommended to use only LASKO REPLACEMENT FILTERS. Some
imitation filters do not comply with Lasko’s quality standards,
resulting in decreased performance of your Humidifier.
*Calculations based on ambient room conditions of 70° F
and 30% relative humidity in a room of average insulation.
CAUTION: To prevent electric shock, always turn Power
Control Knob to OFF position and unplug before servicing.
NOTE: Power Light and Fan are on only when the Humidistat is
turned to a high enough moisture setting.
1. To replace the Evaporative Filter Pad, remove the Jug and Upper
Housing from the Base. Be careful not to let excess water from
pump spill onto furniture or flooring.
Figure 4
• Do not pour water through Exhaust Grill,
doing so may cause damage and personal injury.

7. Discoloration of the Evaporative Pad is normal after
extended use. The discoloration is caused by mineral deposits
in the water, and the degree of discoloration will vary depending upon the amount of mineral content in the water. When
the Filter surface area is thoroughly discolored, or you notice
reduced water usage, it is a good indicator that the Filter
Pad needs to be replaced. The Evaporative Pad should be
replaced at least once every season.
The Replacement Filter to be used in this unit is:

(Available separately)
CLEANING
2. Remove Evaporative Filter Pad Holder from Base and inspect
Small Water Drip Holes for any blockage. (Figure 7)

1. Regular cleaning is necessary to ensure proper and
efficient operation. The frequency of cleaning depends on the
amount of impurities which may be found in the water or how
often the Humidifier is in operation. In either instance, it is
recommended that the Humidifier be cleaned at least once
a week.
Figure 7
• Always be sure the Power Knob is in the OFF
position when plugging Humidifier into a
grounded 120 volt AC wall outlet.
NOTE: The bottom of the Jug may
be unscrewed for easy cleaning.
(Figure 9)
• To prevent risk of electrical shock and injury to
persons, do not plug Humidifier into electrical
outlet with wet hands.
The presence of water flow in the Water Show Window indicates
the circulation of water to the Filter. (Figure 5)
1. It is recommended that all Humidifiers be cleaned prior to use.
Please read Cleaning Instructions for Base and Jug cleaning.
2. Use the convenient Carrying Handle found on the bottom of
the Water Jug to bring it to a faucet. The Water Jug features a
‘Quick Fill/Quick Empty’ Spout. To fill, hold Jug upside down
by the Handle. Use thumb to press down Stopper Lever, and fill
Jug. Fill the Water Jug with cool tap water. Never use hot water.
