Air Purifier F.A.Q.

1. How big of an area will this clean?

Winix Air Purifiers are independently rated for a Clean Air Delivery Rate (CADR) by the Association of Home Appliance Manufacturers (AHAM) http://ahamverifide.org/search-for-products/room-air-cleaners/. An optimal room size is recommended by AHAM for all machines. Winix adheres to these AHAM ratings. However, we also state our recommended maximum room size for certain machines where it is helpful. Not all manufacturers adhere to AHAM.

2. Are air cleaners good for allergy sufferers?

Allergies affect every person differently. Although Winix air purifiers are very effective at removing a myriad of contaminants from the air in your home, it is impossible for us to anticipate everyone’s environment and medical condition. What we do know is that our air purifiers are excellent at reducing airborne pollutants such as dust, smoke, pollen, and pet dander. We use safe and effective technologies that are capable of bringing you the best in-home air quality we can offer. If you suffer from allergies – we sincerely hope that our product helps you breathe easy.

3. What certifications do Winix’s air purifiers have?

We feel that it is extremely important to provide customers with as many certifications as available, in order to provide assurance of product effectiveness.

  • Winix proudly participates in the official AHAM (Association of Home Appliance Manufacturers) Clean Air Delivery Rate (CADR) program so that you can compare air cleaners on a fair and even basis for their removal of Dust, Smoke and Pollen.
  • Energy Star is a program which provides certification to consumer products which meet certain standards of energy efficiency. All Winix Air Cleaners are Energy Star qualified products.
  • UL (Underwriter’s Laboratory) – protecting consumers with rigorous testing of products for safety and performance. UL Listing means that UL has tested representative samples of the product and determined that it meets UL’s requirements. These requirements are based primarily on UL’s published and nationally recognized Standards for Safety. All electrical products sold by Winix in North America are UL Listed.
  • CARB – The California Air Resources Board, also known as CARB or ARB, is the “Clean Air Agency” of the California State Government. All Winix Air Purifiers sold in North America are CARB tested, approved and issues with an EO certificate by them.
  • ECARF & Allergy UK Seal of Approval – The European Center for Allergy Research Foundation (ECARF) has set itself to, improve the quality of life of people with allergies by targeting & actively promoting research on allergies. www.ecarf.org .

They are a voice of the allergy sufferers, representing those affected by this multi-organ disease. www.allergyuk.org

4. How often do I need to replace the filters?

One of the great features of a Winix air purifiers is the use of Smart Sensors that detect the real conditions of the environment and adjust the fan speed accordingly. Unlike other brands that use a timer, Winix air purifier’s alert you when your filters need to be changed. This, in turn, saves you money and allows the filters to work more efficiently. Again, this is all based on average usage, and home environments vary from place to place. One pack of filters, which come with every Winix air purifier, will typically last you one year with normal use. If you have a Wi-Fi enabled Winix unit, the Winix Smart app will tell you the status of the filter and will link to the re-order site if required.

5. How do I replace the filter?

Please refer to your manual. A downloadable version is available in the Product Support section. If you have an air cleaner that uses a carbon pre-filter and True HEPA filter, you should place the True HEPA filter in the air cleaner first, followed by the carbon pre-filter. If you use an filter cassette, the tabs should be closest to you and the washable pre-filter pointing towards you as you place the cartridge in the unit.

6. Can I leave my air purifier on all the time?

We recommend doing so because your air purifier uses smart sensors to adjust the fan speed, it will never use more energy than is necessary to maintain a healthy, comfortable environment. By leaving your unit running it will continuously be drawing in the room air and filtering impurities. Our air purifiers have light sensors that adjust the fan speed according to day and night, putting the air purifier into a low-light sleep mode in the dark.

7. Where is the best location to place my air purifier?

As a general rule, place your Winix air purifier where it can have the best air flow. This means it needs to be placed slightly away from the wall and furniture. Be sure to place your Winix air purifier wherever you are going to spend the most amount of time (such as your living room or family room), or where you have the most concern about odors or allergens (such as in your kitchen or where your pets are), or where it helps you the most (such as in your bedroom when you are sleeping).

8. There is an odor coming from my air purifier.

Don’t worry. Sometimes when the unit is new, the materials from the filter can “outgas” when they are first opened. Leave the unit running for a day or so and it should clear up. If you are concerned about this, leave the unit running on high in a separate room during this period…it should clear up overnight.

9. I hear a “buzzing” sound, while my unit is running.

Sometimes when the room is very quiet, you may hear a slight buzz or “electric hum” from the PlasmaWave® generator inside of the unit. This is nothing to worry about. The PlasmaWave® generator uses electricity to create a strong corona discharge causing it to occasionally make a slight noise. It’s working properly to clean the air.

10. What does the Winix Limited Warranty cover?

When installed, operated, and maintained according to all instructions, supplied with this product, Winix, at its discretion, will repair or replace the product if it fails because of a defect in material or workmanship, as determined by Winix.

11. What is 3-Stage Air Cleaning?

Winix’s advanced 3-Stage air cleaning process effectively removes a broad range of air pollutants from your home. Dust, smoke, pollen, odors, pet dander, mold spores, and organic chemicals are all harmful to your home environment and can irritate your respiratory system. Winix’s FresHome™ for example is able to reduce the presence of these pollutants so that you can live comfortably in your home.

12. What is an Activated Carbon Pre-filter?

Winix specially formulated their Activated Carbon Pre-Filter to capture offensive household odors caused by pets, smoke, cooking, and many other odors found within your home. This filter is also coated with CleanCel® to neutralize germs and bacteria upon contact.

13. What is True-HEPA Filtration?

Our True-HEPA Filtration is excellent for reducing 99.97% of respiratory irritants and pollutants down to 0.3 microns in size. This includes: Allergens, pollen, mold spores, dust, pet dander and bacteria.

14. What is Advanced Odor Control (AOC) Washable Carbon Filter?

Our Advanced Odor Control (AOC) Washable Carbon Filter is 3 times more effective at capturing and neutralizing odors created by pets, cooking, smoke, and many other household contaminants found in the air.

15. What is PlasmaWave® Technology?

PlasmaWave® Technology safely breaks apart odors, allergens, chemical vapors, and other pollutants at the molecular level, without causing harmful ozone. PlasmaWave® creates positive and negative ions that combine with natural water vapor to form hydroxyls, which cleans the indoor air. Winix Air Purifiers are tested and certified by the California Air Resources Board (CARB) to be well within very safe emission levels. CARB EO reference numbers are available on request.

16. What does the Air Quality Sensor with Auto-Mode do?

You won’t have to worry about constantly adjusting your FresHome™ air purifier. The Air Quality Sensor allows for you to set your FresHome™ to Auto-Mode and will automatically adjust the cleaning power for optimal performance; working hard when you need it and saving energy when you don’t.

17. 5-Stage Air Cleaning

Winix Signature Series Air Purifier’s combine our advanced technologies to create an effective 5-Stage air cleaning system. The Signature Series removes a broad range of odors, allergens, and other airborne pollutants including: dust, smoke, pollen, pet dander, mold, bacteria, and Volatile Organic Compounds.

18. Air Quality Sensor With Air Quality Indicator

As the Air Quality Sensor detects particles, the Air Quality Indicator will display ambient light to reflect the air quality in the environment. When Sleep Mode is activated, the Air Quality Indicator light is turned off.

19. 4 Fan Speeds (Turbo, High, Medium, Quite)

Your Signature Series air purifier has 4 fan speeds that allow for tranquil whisper, energy efficient, cleaning in Quiet Mode and ultimate performance in Turbo Mode.

Dehumidifier F.A.Q.

1. Why doesn’t my unit draw in water?

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.

2. Why is my unit leaking?

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.

3. How do I remove the pump hose?

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.

4. How should I clean the unit?

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.

5. How do I clean the filters and how often?

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.

6. How much water does the bucket hold?

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.

7. How much energy (electricity) does the dehumidifier use?

With a high fan speed, the 50 pint models use about 640 watts and the 70 pint uses about 7654 watts. Both versions and all of our units are energy star qualified/certified.

8. How high can the pump vertically push the water out of the hose?

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.

9. The fan is running, but not the compressor.

See “unit is not drawing water”

10. The unit never shuts off, is this normal?

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.

11. The dehumidifier seems loud?

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.

12. The dehumidifier is vibrating?

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.

13. The “Bucket Full” light is on, but the bucket is empty?

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.

14. The pump is running, but no water is coming out?

  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.

15. An “E3” error is shown on the display?

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.
