Air purifier filters

The right filter depends on the exact model of your WINIX air purifier or humidifier. For example, the WINIX ZERO uses Filter A, the ZERO-S Filter H, the ZERO Pro Filter T and the T800 Filter GR. Other models may use different filters. Always check the product name or model code on your appliance against the compatibility information on the filter page.

A HEPA filter captures small airborne particles such as fine dust, pollen and dust particles. An activated carbon filter helps reduce certain odours and gaseous substances. A pre-filter captures larger dust particles and hair. Many WINIX filter sets combine several of these components, but the exact combination varies by model.

Replacement frequency depends on the WINIX model and filter type. For many models, the main filter has a recommended interval of about twelve months, while some carbon filters need replacing more often. Heavy use or a dusty environment may affect maintenance needs. Always follow the model-specific replacement guidance in the manual.

Many WINIX air purifiers have a filter indicator showing when the main filter needs checking or replacing. It is also important to follow the prescribed replacement interval. A visibly dirty pre-filter may need cleaning sooner. Check your specific model’s manual for the meaning of the indicator and how to reset it after replacement.

Original WINIX filters are designed for specific WINIX models. Their dimensions, construction and compatibility therefore match those appliances. With an alternative filter, you must check that it is genuinely suitable and meets the required specifications. Use the official WINIX model and filter information to make the right choice.

Compatibility is listed in the original WINIX filter’s product information and in your air purifier’s manual. Check the exact model name, as similarly named models may use different filters. If in doubt, consult the WINIX filter page or contact customer service before ordering a replacement.
