CADR (Clean Air Delivery Rate) is the amount of purified air per hour, expressed in m³/h. A higher CADR means that an appliance can filter more air per hour. Also check the maximum recommended floor area in m² in the model’s technical specifications. Performance in your room also depends on the fan setting, furnishings and use.

A WINIX HEPA air purifier can filter airborne allergens such as pollen and dander from the air it draws in. Whether symptoms improve varies by person and environment. Air filtration complements ventilation and reducing sources of allergens; it does not replace medical treatment.

WINIX air purifiers alert you when the filters need replacing. One filter pack, supplied with every WINIX air purifier, lasts approximately one year under normal use. If you have a WINIX air purifier with Wi-Fi, the WINIX Smart App shows the filter status.

First check which filter fits your model. Unplug the appliance and follow the steps in the manual for your model. Remove the protective wrapping from the new filter, fit the parts in the specified order, then reset the filter indicator as described in the manual. Separate filter sets and All-in-One cartridges may require different procedures.

We even recommend it, because the smart air-quality sensors in your air purifier adjust the fan speed so it never uses more energy than needed to maintain healthy air quality. Our air purifiers also have a light sensor that switches the appliance to sleep mode in the dark, with dimmed lights and low power. Leaving your purifier on lets it continuously draw in room air and filter out pollutants.

In general, place your WINIX air purifier where it can create the best airflow, preferably a little away from walls and furniture. Put it where you spend most of your time, such as your bedroom, living room or home office, or where odours or allergens bother you most, such as the kitchen or an area used by pets.

When the appliance is new, the filter materials sometimes need to air out. Let the appliance run for a day; the smell should then disappear. If it bothers you, you can place the appliance in a separate room while it airs out.

When it is very quiet, you may sometimes hear a slight hum or electrical buzz from the PlasmaWave^® generator inside the appliance. This is nothing to worry about. The PlasmaWave^® generator uses electricity to create a strong corona discharge, which occasionally produces a faint buzz. This simply means everything is working correctly. You can switch the PlasmaWave^® function off if you wish, but this reduces cleaning performance.

An activated carbon filter helps reduce certain odours and gaseous substances in the air drawn into the appliance. The HEPA filter has a different purpose: it captures airborne particles. Carbon filter performance and maintenance vary by model; consult the relevant filter information.

A HEPA filter captures fine airborne particles such as dust, pollen and dander from the air passing through it. The stated filtration efficiency applies to the filter itself and does not guarantee that the same percentage of particles will be removed from the entire room.

The Advanced Odor Control (AOC) carbon filter helps reduce certain household odours.

PlasmaWave® is an additional cleaning stage alongside the pre-filter, carbon filter and HEPA filter. The technology uses positive and negative ions. See the explanation of PlasmaWave® and your model’s manual for information on operation and controls.

With Auto mode, you do not need to adjust your WINIX air purifier yourself. The air-quality sensor lets you set the appliance to Auto mode, which automatically adjusts the cleaning power for optimum performance: working hard when needed and saving energy whenever possible.
