HSP002 4-in-1 Air Purifier Filter Replacement- Full-Range Multi-Layer Purification 

1. HSP002 4-in-1 Air Filter: Multi-dimensional Purification for Comprehensive Coverage

Four-layer structure, addressing multiple pollutants in one step.

The HSP002 air filter features a 4-in-1 integrated design: pre-filtration(blue color) + HEPA H13 + honeycomb activated carbon + cold catalyst filter(green color). This four-layer structure purifies the air layer by layer: from intercepting large particles to capturing fine pollutants, and then to adsorbing odors and decomposing harmful gases. No additional filters are needed; one device achieves comprehensive air purification, suitable for home, office, and commercial use.

2. First-layer Pre-filtration: Intercepting Large Particles and Extending the Lifespan of the Core Filter Material

Blocking hair and dust first, protecting subsequent purification layers.

The HSP002's first-layer pre-filtration uses high-density polyester fiber material, which prioritizes intercepting large particles such as hair, dander, and dust in the air, preventing them from directly entering the subsequent core filter material and causing blockage. The pre-filter is washable and reusable; daily cleaning simply requires rinsing with water and air drying. This extends the lifespan of the core layers (HEPA, activated carbon, etc.) by over 30%, balancing purification effectiveness with operating costs.

3. Second Layer: HEPA H13 99.97% Interception of 0.3 Micron Pollutants

Precisely captures allergens, creating a clean breathing environment.

The core layer uses HEPA H13 grade filter material with a filtration efficiency of up to 99.97%, precisely capturing fine pollutants as small as 0.3 microns, such as PM2.5, pollen, dust mites, and bacteria. Specifically designed for people with allergies, families with infants, and other environments sensitive to air quality, it effectively reduces the concentration of allergens in the air, minimizing the risk of respiratory discomfort. It is a key protective layer for creating a clean indoor environment.

4. Third Layer Honeycomb Activated Carbon: Powerful Adsorption of Odors and Harmful Gases

The honeycomb structure expands adsorption capacity by 2 times.

The third layer of HSP002 uses honeycomb activated carbon. Compared to ordinary granular activated carbon, the honeycomb structure has a more uniform pore distribution and a larger contact area, increasing adsorption capacity by more than 2 times. It can powerfully adsorb harmful gases and odors such as formaldehyde, benzene, TVOC, cooking fumes, and pet odors. For scenarios with strong odors, such as newly renovated homes, smoking environments, and kitchens, the purification effect is faster and longer-lasting.

5. Fourth Layer Cold Catalyst: Decomposes Harmful Gases Without Secondary Pollution

Continuous Action at Room Temperature for More Thorough Purification

The final cold catalyst filter can catalyze the decomposition of harmful gases such as formaldehyde and benzene at room temperature, converting them into carbon dioxide and water, avoiding the problem of secondary release after activated carbon adsorption saturation. The cold catalyst does not require light and works continuously, forming a dual protection of "adsorption + decomposition" with the honeycomb activated carbon, making air purification more thorough and safer, especially suitable for long-term closed indoor spaces.
