People need a certain level of humidity to be comfortable. In the winter, indoor humidity can be extremely low, and the lack of humidity can dry out your skin and mucous membranes. Low humidity also makes the air feel colder than it actually is. Dry air can also dry out the wood in the walls and floors of our houses. As the drying wood shrinks, it can cause creaks in floors and cracks in drywall and plaster. Dry air also increases static electricity.

It can maintain a certain level of humidity for plants and pets in your home.

Regular cleaning is recommended; approximately every 1–2 times a week. When storing the unit, it is recommended to pour any excess water out and clean it with a soft, damp cloth. Let dry completely before storing.

An ultrasonic humidifier uses a metal diaphragm vibrating at an ultrasonic frequency to create water droplets.

It is recommended that you place the product up on an elevated surface and not on the floor. Placing it on a table or nightstand during operation is suggested.

*DO NOT PLACE UNIT DIRECTLY ON CARPET, TOWELS, BLANKETS, HARD WOOD FLOORS OR OTHER ABSORBENT SURFACES as these surfaces may be damaged by water or moisture exposure.

Forty to fifty-five percent (40–55%) humidity is considered within the comfortable range.
Any humidity level below thirty percent (30%) is considered dry.

The warm mist feature provides a soothing, comfortable moisture when it comes in contact with your skin. It also has a slightly higher mist output. The cool mist feature simply uses the temperature if the water in the tank and disperses it without any heat.

No. It is recommended to put room temperature water into the tank for humidifying. When the warm mist feature is activated, the water inside the unit is heated up to 120F and then cooled down to 100F and give the output of comfort and safe mist. Heating the water before putting it in the tank may cause some damage to the ultrasonic membrane.

It is 100F, so it is safe to touch.

The unit will shut down before the base of the unit runs out of water (when the tank is empty), so the heating part will never be out of water, which means it is perfectly safe and will not cause any fire.

Unfortunately, no. In order to heat up the room temperature, the output mist has to be above 160F, but as this can cause burns, we avoided the temperature from going this high. The mist is comfortable and gives you a warm feeling when touching your skin.

You can use either distilled or regular tap water. When using any tap water where the water is hard water, we recommend using demineralization capsules which can be found on winixamerica.com.

The warranty is 1-year limited. For detailed warranty specifications please refer to the warranty section in the instruction manual.

Forty to fifty-five percent (40–55%) humidity is considered within the comfortable range. Any humidity level below thirty percent (30%) is considered dry.

Yes, you can use the Night Mood Light at 0% to do this.

Winix Ultrasonic Humidifiers don’t require filters, which is one of the biggest benefits about the ultrasonic type humidifiers. If you want to upgrade or enhance your Winix Humidifier, we offer demineralization capsules and aroma pad accessories.

(sold separately for L100, L060/061)

• Reduces the mineral residue in your unit.
• Results in less cleaning and lengthens the unit’s lifespan.
• For optimal performance, replace each capsule every 10 tank fillings or when you notice an increase of white residue.
• The replacement period of the demineralization capsule could differ based on the quality of water.
• Consider using distilled water if white residue persists.

Warning: never use water softening additives in your humidifier.

No, the capsule is not reusable if you remove it from water. Once you have submerged the demineralization capsule in water, you have started the capsules lifespan. If removed from water (other than for tank cleanings) the effectiveness of the capsule will be lost.

The capsule will not lose its effectiveness. The capsules efficiency does change according to the time period it has been submerged in the same water. The capsules efficiency changes when it is exposed to new water in the tank.

• New design and soothing relief: WINIX Waterless Vaporizer Scent Pads are non-medicated refill pads designed with Polymer PP to release soothing relief vapors to enhance your humidification experience and to help provide added comfort.
• Provides long-lasting comfort per pad: Each pre-soaked aroma pad offers 48 hours of long-lasting comfort.
  No spills or messy refilling: These refill pads are easy to use and install, preventing messy spills and doing away with the need for constant refilling.
• These pads are designed for use with WINIX Ultrasonic humidifier products: L100, L200, L201.

It is not recommended that you add aromatherapy oils to either the L200 or L100 Winix Humidifier. The water tank for these two units were not tested to be compliant with any aromatherapy other than their designated pre-soaked aroma pads. Use of aromatherapy oils into the water tanks of these units may result in a defect, cease of operation and void of warranty.

• L200/L201 fills from the top.
• L100 fills from the bottom.
• L060/061 fills from the top.

Yes

The humidity you want achieved can be Increased or Decreased in Increments of 5% (40%-60%). If 45% is set, it will turn off once relative humidity reaches 50% and will kick back on once the relative humidity is 40% of below. For another example this is how the temperature settings will work:

• When the set humidity level is reached (50%), the humidifier will cycle off until the humidity in the room drops 5% below that set level (45%).
• When the set humidity level is set (50%), the humidifier will cycle off when the humidity in the room reaches 5% above that set level (55%).

This may happen when the humidity level close to the unit is not lower than 5% lower from your set humidity. In this case the unit will not turn on the humidification function. If you still want to have more moisture even at a level higher than 55% (which is 5% lower than the highest level of 60%), please use the continuous mode.

(Remember that it is based on the humidity level detected by the sensor inside the unit, which is detecting the humidity of the air very close to the unit, so it may be different from what your room humidistat will show you)

The mist level can be increased or decreased by pressing the Adjustable Mist Level. The Adjustable Mist Level will cycle up and down through the mist levels while it is running.

• For example, if you set the Mist Level to be 3, then the lights will sequentially flash up from 1, 2, 3 and then back down to 1, 2, and 3.

No, the unit will shut off when it is out of water because there is a water Empty Tank Alarm.

Depending on your Winix Humidifier model, the Night Mood Light will either dim or change the color of the lights on the unit.

For L200/L201/100

The Night Mood Light comes in four dimmable stages from 100% -> 50% -> 20% -> 0% (Off).

When set at 0%, the lights of the control panel and the light inside the tank will totally be off.

On other percentages, it will be dimmed according to the percentage.

For L200/201

In order to get the unit out of sleep mode when you are on 0%, press any button on the control panel to wake the display.

For L60/L61

There is no dimming function, but you can change between 3 Night Mood Light Colors (red, blue, amber) and turn the light off.

All Winix Humidifiers can be used in various size of room depending on how fast you want the entire room to be have an increased level of moisture. It is recommended to use L200/L201 in a medium to large size rooms, L100 in medium size rooms, and L60/61 in small to medium size room to have comfortable humidity level in a short period of time.

Clean the ultrasonic module of the humidifier at least once or twice a week.

Cleaning the ultrasonic transducer

• Tilt it in the direction of the air hinge when disposing of the water in the main body.
• Never touch the transducer/ultrasonic membrane with your fingers; the natural oils in the skin can damage the surface.
• Never clean the ultrasonic membrane by scraping with a hard object. Scratching the surface of the vibrator with a sharp object may cause the Mist Output to weaken or cause failure.
• Never submerge the base in water or any other liquid.

Deep cleaning (with vinegar)

• Before and after storing the humidifier for a long period of time, dry the water in the Mist Output completely and wipe it clean.
• Clean the tank, reservoir, tank cap, and the transducer / ultrasonic membrane with a 10:1 mixture of water and white vinegar.
• Fill the tank with diluted vinegar water to the maximum level. Put about 400 mL of mixed water into the main body.
• Fill the water tank and main body with water and leave for 30 to 60 minutes.
• Pour mixed water and rinse with clean tap water 2 to 3 times.
• Dry the parts in a well-shaded place.
• Reassemble the dried unit.

In order for the room to be fully humidified to the level that you had set, it may take a few hours depending on the room size that you are using.

1. The L200 can only detect the humidity close to the air inlet grill

(With the air that is being sucked into the sensor inside the grill)

2. There is no air flow speed further than 3.9in(10cm) away from the inlet grill

The air is being sucked in through the small inlet grill in the back of the unit, and the humidity sensor senses the humidity level based on that.

LightCel™ UV+ LED Technology removes contaminants present in water, ensuring a healthier mist for you and your family.

Unlike other air treatment devices (Such as Air Purifiers or Dehumidifiers), a humidifier gives out a very small output of air flow from the unit. So, the humidity level sensed in the machine could be different from the room humidity, and the unit is run based on the humidity of the air being sucked into the unit during Humidity set mode.

In order for the room to be fully humidified to the level that you have chosen; it may take a few hours depending on the room size that you are using.

Please make sure to ensure a certain distance between the unit’s inlet grill (in the back of the unit) and the wall (12~18 inches). In case it is too close to the wall, the output mist may be sucked into the inlet grill, causing the sensor to sense higher humidity level than normal)

• Insert the power plug carefully.
• Check if there is water in the water tank and add water to drive.

• Is the water tank empty?

– Please put more than half of the water in the water tank.

• Is the nozzle and cover well seated?

– Please install the cover correctly.

• Please clean the ultrasonic module.

• Is the interior of the humidifier or water tank contaminated?

– Clean the inside of the main body and the water tank.

• Did you leave the water in the water tank and humidity reservoir unattended?

– Change the water in the water tank with new tap water every day. Also, throw away the remaining water from the main body and the water tank every day.

• Is it immediately after setting up the water tank?

– After a few moments, the water in the water tank fills the reservoir and the Empty Tank Alarm turns off.

• Is it tilted?

– Drain the water inside the humidifier and place it on a flat, stable surface.

• Unplug the humidifier and plug it back in.
• Press to turn the humidifier on. Add at least 2 cups / 475 mL of filtered water to the water tank.

• Press to use a higher mist setting.
• There may be mineral buildup inside the base.
• Clean the transducer with a cleaning brush and white vinegar.
• Water may be dirty or has been sitting in the tank for a long period of time.
• Clean the humidifier and refill with clean water.
• Make sure the air outlet is not blocked.

• The humidifier uses up water based on the environmental temperature and humidity.
• If your environment is cold and/ or dry, the humidifier will run out of water faster.

• If the humidifier is new, remove the top cover, and place the water tank in a cool, dry place for 12 hours.
• Water may be dirty or has been sitting in the tank for a long period of time.
• Clean the humidifier and refill with clean water.

• This is caused by using water with high mineral content.
• Use filtered water to fill the humidifier.
• Clean the humidifier.

• Make sure the tank is properly placed on the base by aligning the indicator marks. Make sure the sealing ring inside the water tank is securely in place.
• If necessary, clean the sealing ring and make sure it can open and close normally.
• Make sure the float is correctly installed and securely in place.

Winix Dehumidifier’s may not be drawing in water for several reasons:

• If the units has been drawing in water for the past few weeks, it could be because the unit is working properly and has already reduced the overall humidity level in the room.
• If you are using the pump function, the pump may be turning on when you are not there and emptying the bucket.
• Is it cold outside? Sometimes the moisture within the air is already low. This is especially true in cooler months, and a dehumidifier may not be needed at this particular time.
• The temperature is below 65 degrees F. When temperatures are around 65 degrees and below, there is a likelihood for frost to develop on the evaporative coils depending on the moisture level in the air. When this happens, the compressor will NOT run (the part responsible for dehumidifying) and the fan will run to try and melt the frost. Because the compressor is not running, it cannot draw water in the bucket. The frost must first be removed and or the temperature must rise before the compressor will turn on again and dehumidify.
• Please note: water in the bucket may not be immediate; you must allow it to run for a length of time.

Please remove the cover from the gravity drain side located at the back of the unit. You will see a drain pipe. This is about a ½”  wide and goes up 3″ so you will need something flexible to clean it out with. You can use pipe cleaners or a flexible drinking straw to do the following: Insert 2-3 pipe cleaners through that opening to unclog and clean the sludge buildup. Be careful when doing this as there may be water inside that may rush out once it’s unclogged/cleaned out.

Turn off the power; where the connection of the hose is located there is a white “quick-connect” fitting (locking ring). Taking your fingernail press the ring in. While holding the ring flush against the fitting, pull the hose out with the other hand.

• Be patient, it will come out
• Do NOT pull the hose out without pushing the ring against the fitting as this may break the connector and the pump option will not work.
• Always remember to replace the grey rubber cap on the pump connector when the pump is not in use.

Most important part to clean is on the front gill and filter. Remove the filter and clean. If the filter gets too dirty, it may restrict air flow and reduce performance. All other areas of the unit may be cleaned with a mild detergent and damp cloth.

Remove the front grill by pulling from the base and lifting off the top. The filter will be located right behind it. Remove the filter and clean by wiping it down with a damp cloth or paper towel, or even running it under a faucet can work as well. Attach the filter back to the unit and install the front grill by placing the tabs at the top first and snapping the base back into place.

16.88 pints; however this is a common misconception about the pint capacity; the unit will be rated depending on how much moisture it will remove in a 24 hour period. So you will have to empty the bucket several times a day to meet the rating.

With a high fan speed, the 50 pint models use about 640 watts and the 70 pint uses about 710 watts. Both versions and all of our units are energy star qualified/certified.

The units comes with a 18″ long hose, but it is recommended that one pumps a maximum of 15″, to ensure the pump works efficiently.

See “unit is not drawing water”

First check to make sure the unit is not in continuous mode; if not, the humidity in the room is higher than the set humidity level that you programmed. The unit will thus continue to run until it has reached its target level.

• Example: Set target to 50% humidity; humidity in the room is 80%, the unit will continue to run until the unit detects 50%
• You may either increase the target humidity level to a higher level or set the unit in off timer mode (for models: WDH751 & DHD501), or cycle mode (for models: WDH851 and WDH871). This will run for a set amount of time before turning off; this is ideal for the warmer parts of the day.

Dehumidifiers are generally loud machines; they have both a motor to run the fan, as well as, a compressor to dehumidify which may not only be loud at times, but may also have poor sound quality. Typically, dehumidifiers are placed in areas of the home that are not used often because of the noise the unit produces. The noise level is comparable to window air conditions.

Due to the compressor, the dehumidifier will not only make a loud noise when running, but it will also create a vibration, which is normal. If the unit is on an uneven surface, it may vibrate even worse.

Make sure the bucket is seated completely flush inside the unit. It may take effort to remove the bucket and reinsert it by tapping it to ensure it has a tight fit. If still on, remove bucket and check the float to ensure it is operation properly by moving it up and down. There are plastic tabs that keep it in place and sometimes that can come out causing this error.

1. Check the line of the pump drain tube, please make sure there are no tight bends or crimps in the hose line.
2. Remove the hose and make sure there is nothing inside the tube, blocking the line.
3. Unplug the unit, remove the hose, reinstall the hose and plug it back in.
4. Remove the bucket, there is a connection at the base of the bucket you need to find. Re-insert the bucket back into the unit and make sure the bucket is completely seated to ensure that seal is tight against the unit. If the seal is not connected, the pump may run with no water able to pass from the bucket to the unit.

E3 is an error case in which the unit believes there is blockage in the line. There could be several causes.

1. Check the line of the pump drain tube, please make sure there are no tight bends, or crimps in the hose line.
2. Remove the hose and make sure nothing inside the tube is blocking the line.
3. Unplug the unit, remove the hose, reinstall the hose and plug the unit back in.
4. Remove the bucket, there is a connection at the base of the bucket that you need to find. Reinsert the bucket back into the unit and make sure the bucket is completely sealed to ensure that seal is tight against the unit. If the seal is not connected, the pump may run, but no water will be able to pass from the bucket to the unit.
