WINIX 5520 Air Purifier

The WINIX 5520 Air Purifier combines intelligent features with a multi-stage filtration system to help improve indoor air quality. Its True HEPA filtration, activated carbon filter, smart sensors, and automatic operating modes make it a versatile air purification solution.

1. Smart Wi-Fi Connectivity & App Control

Built-in Wi-Fi connectivity allows users to manage supported purifier settings through the Winix Smart App. The WINIX 5520 also supports compatible Amazon Alexa voice controls for greater convenience.

2. Intelligent Air Quality Sensors

Dual smart sensors monitor indoor air quality and provide visual feedback through a three-colour LED air quality indicator. This helps users understand changes in indoor air conditions.

3. Automatic Air Purification

The intelligent Auto Mode automatically adjusts fan speed based on detected air quality conditions, helping maintain effective filtration without frequent manual adjustments.

4. Quiet Operation & Automatic Sleep Mode

With an operating noise level starting from approximately 23.5 dB, the WINIX 5520 supports quieter operation. Its Automatic Sleep Mode adjusts settings when the surrounding environment becomes dark, making it suitable for nighttime use.

5. Five Adjustable Fan Speeds

The purifier offers five fan speed settings, providing flexibility for different purification requirements and indoor conditions.

The WINIX 5520 is a true HEPA air purifier that combines particle filtration, activated carbon, and PlasmaWave® technology.

Stage 1 – Washable Fine Mesh Pre-Filter

Captures larger particles such as dust, hair, and lint while helping protect subsequent filtration layers.

Stage 2 – Advanced Odor Control (AOC™) Carbon Filter

Helps reduce household odours associated with cooking, pets, and smoke. The activated carbon layer also helps reduce certain volatile organic compounds (VOCs).

Stage 3 – True HEPA Filtration

Captures up to 99.99% of airborne particles in the 0.1–0.3 micron range under specified laboratory testing conditions, including fine dust, pollen, and other airborne allergens.

Stage 4 – PlasmaWave® Technology

PlasmaWave® provides an additional air-cleaning stage that complements the mechanical filtration system to help address certain indoor air pollutants.

Together, these filtration stages offer a comprehensive approach to improving everyday indoor air quality.

Regular maintenance helps your WINIX 5520 Air Purifier maintain consistent airflow and filtration performance. Using compatible WINIX replacement filters and following recommended maintenance practices supports reliable everyday operation.

Washable Pre-Filter Cleaning

Clean the WINIX fine mesh pre-filter periodically to remove accumulated dust, hair, and larger particles. Follow the manufacturer's cleaning instructions before reinstalling the filter.

True HEPA & Carbon Filter Replacement

The WINIX True HEPA and AOC™ activated carbon filters are not washable. WINIX recommends replacing them approximately every 12 months under normal operating conditions. Replacement frequency may vary depending on usage and indoor air quality.

Filter Replacement Indicator

The built-in WINIX filter replacement indicator helps notify users when the main filters need to be replaced, making routine maintenance more convenient.

Compatible WINIX Replacement Filter

The WINIX 5520 uses the genuine WINIX Filter replacement filter set. Using compatible WINIX filters helps maintain the purifier's intended airflow, filtration performance, and product compatibility.
