W300 Washable ESP Filter Air Purifier with Formaldehyde Decomposition for 120㎡ Commercial Air Disinfection Purifier

The W300 Plasma Washable ESP Air Disinfection Purifier delivers multi-stage air treatment combining cold-plasma technology, washable electrostatic filtration, and manganese-dioxide formaldehyde decomposition. Unlike traditional air purifiers that require frequent filter purchases, its core filters are fully washable and reusable, enabling zero-consumable operation and avoiding secondary pollution.
Capable of handling spaces up to 120㎡, this unit works great for both residential and commercial settings. It starts improving air quality within 15 minutes of startup and completes full-cycle air treatment after 60-minute continuous operation. It achieves up to 99.9% sanitization performance against airborne contaminants while supporting human-machine coexistence — you can safely run it while people stay inside the room.

1. 1. Pre-Filter

   Traps large-size pollutants ≥5μm including dust, pet hair, lint, and coarse debris. Washable for repeated use and protects downstream high-performance filter components.

2. 2. Washable ESP Electrostatic Module

   Airborne particles receive negative electric charges as they pass the electrostatic zone. Charged particles are captured by oppositely-charged collector plates. This system captures ultra-fine aerosols, dust, pollen, and smoke particles down to 0.1 μm. The high-voltage electric field suppresses airborne microorganisms attached to particles. All collector plates can be rinsed and reused, cutting long-term running costs.

3. 3. Active Manganese Dioxide Formaldehyde Decomposition Filter

   Instead of merely adsorbing formaldehyde, this catalytic filter drives chemical reactions between formaldehyde and ambient oxygen, breaking formaldehyde down into harmless carbon dioxide and water. The catalyst material is not consumed during operation, so no periodic filter swap-out is needed.

4. 4. Cold Plasma Module

   Cold plasma splits air molecules and releases active oxidative factors to treat airborne pollutants and odors within seconds. Zero harmful emission and no radiation, safe for occupied rooms.

• Washable & Reusable Filters, No Consumables

  Pre-filter and ESP collector module can be washed, eliminating ongoing filter replacement expense and secondary pollution.

• Dual-Mode Air Sanitization

  Combination of high-voltage electrostatic field plus cold plasma delivers up to 99.9% sanitization performance for airborne contaminants.

• Catalytic Formaldehyde Decomposition

  Manganese-based catalyst chemically breaks formaldehyde, avoiding the risk of adsorbed-formaldehyde re-release.
