EVAPORATIVE HIGH PERFORMANCE
RECIRCULATING DIGITAL HUMIDIFIER
This Humidifier is not intended to be used in
commercial, industrial or agricultural settings.
IMPORTANT SAFETY INSTRUCTIONS
READ AND SAVE THESE INSTRUCTIONS
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 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.
IMPORTANT SAFETY INSTRUCTIONS
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.
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
DO ES NOT FUNCTION PROPERLY, IT MAY BE DUE TO THE
SAFETY DEVICE INCORPORATED IN THIS PLUG. RETURN TO
DO NOT pour water into Grill. DO NOT spill water on Control Panel.
Water should only be poured into the Unit using the Jug.

MONDAY-FRIDAY, BETWEEN 8:00AM AND 5:00PM EST. IF THE
PLUG WARNING LABEL IS MISSING OR DAMAGED, CALL THE
TOLL FREE NUMER FOR A REPLACEMENT LABEL.
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.

FILTER CARE
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.
CAUTION: To prevent electric shock, always turn Power
Control Knob to OFF position and unplug before servicing.
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.
2. Remove Evaporative Filter Pad Holder from Base and in-
spect Small Water Drip Holes for any blockage.

4. Insert new Filter into Holder, snap closed, and reinstall
Holder into Base. The Filter will only t into the Holder
one way. Make sure the Rounded side of the Filter Holder
is facing outward. Replace Upper Housing, then Water Jug
into Base.
5. To increase the life of your Filter Pad turn
Filter around (so the bottom of Filter is
now at the top).
6. Filter life may be extended by cleaning
the Filter in a 20% vinegar solution. To
clean Filter, mix one part undiluted vinegar with four parts
warm tap water. Soak the Filter in this solution for 20 minutes, rinse Filter thoroughly with warm water to remove
vinegar odor.

DO NOT FLATTEN, SQUEEZE OR TWIST FILTER WHEN
CLEANING
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:
The Lasko Replacement Evaporative Pad Model THF 8
(Available separately)
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 howoften
the Humidifier is in operation. In either instance, it
is recommended that the
Humidifier be cleaned at
least once a week.
NOTE: The bottom of the Jug
may be unscrewed for easy
cleaning.
CAUTION: Make sure bottom of
jug is securely fastened to Jug
before reinstalling into Base.
2. TO DESCALE BASE AND
JUG: Mix one part undi-
luted white vinegar with four parts warm tap water. Let
vinegar solution stand for 20 minutes then wipe away any
scale buildup using a soft brush or cloth. Do not use soap
or detergents and never use an abrasive cleaner.
3. TO DISINFECT BASE AND JUG: Fill Jug with 1 teaspoon
of chlorine bleach and 1 gallon of water. Let solution stand
for 20 minutes. Carefully empty Jug and rinse well with
water until bleach smell is gone.
