Zero-Consumable Washable Filter Air Purifier with Cold-Plasma ESP for 120㎡ Coverage Air Cleaner

Tired of endless, expensive filter replacements for your air purifier? Most air cleaners force you to buy new filters every few months, adding up to high long-term running costs. The W300 changes the game: its core filter components are fully washable and reusable, eliminating recurring consumable expenses without sacrificing purification power.

Built for large-volume air processing, this all-in-one unit handles fine airborne particles, formaldehyde, smoke and unpleasant odors. Optimized for areas up to 120㎡, it is equally suited for busy commercial spaces and large residential rooms. Featuring smart Tuya Wi-Fi connectivity and multi-sensor real-time air quality feedback, it runs safely even while people occupy the room.

• Zero-Consumable Washable Filter DesignPre-filter and ESP electrostatic collection cell can be rinsed clean for repeated use. Say goodbye to frequent filter-ordering costs.
• Multi-Layer Comprehensive Air Processing4-stage workflow: coarse particle interception, electrostatic fine-particle capture, catalytic formaldehyde breakdown, cold-plasma odour treatment. Captures pollutants down to 0.1μm.
• Catalytic Formaldehyde Breakdown, Not Just AdsorptionSpecial manganese-dioxide catalyst triggers a chemical reaction, converting formaldehyde into harmless water and carbon dioxide. No risk of trapped formaldehyde leaking back into indoor air.
• Smart Tuya Wi-Fi App-Enabled ControlAdjust fan speed, switch modes, set timers remotely via your smartphone. Supports Manual / Auto / Sleep / Timer operation modes.
• Full Suite of Environmental SensorsOnboard PM2.5, CO₂, temperature and humidity sensors. Real-time digital screen displays your indoor air condition at a glance.
• Safe for Occupied RoomsNo hazardous chemical discharge, zero radiation. The unit can operate continuously while people stay inside the space.
• Thoughtful Practical FunctionsTouch-sensitive control panel, child-lock safety lock, four-speed fan adjustment, filter cleaning reminder for simple day-to-day management.

1. 1 Pre-Filter: First-Line Coarse Interception The initial mesh catches hair, pet fur, lint and dust particles larger than 5μm. It protects the precision inner filter components from heavy soiling and can be quickly rinsed clean.
2. 2 ESP Electrostatic Collection Cell: Catch Ultra-Fine Pollutants (0.1μm) As air flows through the high-voltage electrostatic zone, tiny airborne particles receive an electrical charge. Oppositely charged collector plates attract and trap ultra-fine contaminants including smoke, pollen and aerosols as small as 0.1μm. After accumulation of dirt, you simply remove, wash and reinstall this cell.
3. 3 Manganese-Dioxide Catalytic Filter: Destroy Formaldehyde at Source Instead of trapping formaldehyde inside filter material like standard activated-carbon filters, this catalytic layer drives a stable chemical reaction. Formaldehyde reacts with ambient oxygen and decomposes into harmless water and CO₂. The catalyst itself does not get used up with regular operation.
4. 4 Cold-Plasma Module: Reduce Odours & Treat Air Molecules Cold-plasma technology generates reactive oxidative agents to neutralise indoor odour compounds within seconds. It produces no by-products dangerous to humans and works well in occupied rooms.
