  1. How big of an area will this clean? What air purifier should I choose?

    Be careful when you are selecting an air purifier. Many companies have their own way of measuring the "area" that their air purifiers clean. By taking this subjective measurement and applying their own formula for calculating the results, makes it difficult to compare between companies. Our advice is to refer to the official AHAM (Association of Home Appliance Manufacturers) rating system for air purifiers. They use a system that measures the CADR (Clean Air Delivery Rate) of an air cleaner, in order to come up with the recommended advertised room size. It may not be a perfect system, but at least it allows for an honest comparison between brands to be made. So, even if you decide not to purchase a Winix product, we highly recommend that you purchase from a manufacturer that is using this official, honest, and respectable certification process.
  2. Are air cleaners good for allergy sufferers?

    Allergies affect every person differently, and, although our air purifiers are effective at removing a myriad of contaminant 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 breath easy.
  3. What certifications do Winix's air purifiers have?

    Winix is proud that our entire range of Air Cleaners carries these certifications… AHAM (Association of Home Appliance Manufacturers): Winix proudly participates in the official AHAM 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: All Winix Air Cleaners are Energy Star qualified products. UL (Underwriter's Laboratory): Protecting consumers with rigorous testing of products for safety and performance.
  4. How often do I need to replace the filters?

    One of the great features of the Winix's 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's air purifiers alert you when your filters need to be changed. Saving you money and working efficiently. Again, this is all based on average usage, and home environments vary from place to place.
  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 HEPA filter you should place the HEPA filter in the air cleaner first, followed by the carbon pre-filter. If you use an Ultimate Filter, 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 be using more energy that 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. Some of our air purifiers have light sensors that adjust their fan speed according to day and night.
  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 away from the wall and furniture The ideal location would be the middle of the room, but realistically that is probably not where most people want to leave their air purifier. 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 quite, you may hear a slight buzz or "electric hum" from the PlasmaWaveTM generator inside of the unit. This is nothing to worry about. Because the PlasmaWaveTM generator uses electricity to create a strong corona discharge it may make a slight noise. It's working properly to clean the air.
