HSP001 Air Purifier 2-Pack Air Filter Pre-Filter H13 HEPA Carbon Photocatalyst 

1. HSP001 Dual-Piece Filter: Dual-Layer Function for Comprehensive Purification

Two pieces work together to cover multiple pollution scenarios

The HSP001 air filter features a dual-piece design: one piece combines pre-filtration with H13 HEPA filters to intercept impurities and fine pollutants; the other piece integrates activated carbon and photocatalysis, focusing on adsorbing odors and decomposing harmful gases. No additional accessories are needed; the two pieces work together to complete the entire purification process from "pre-filtration - fine filtration - odor removal - decomposition," making it suitable for use in homes, offices, baby rooms, and other scenarios.

2. First Filter: Pre-filtration + H13 HEPA - Blocks Large Particles First, Then Captures Fine Pollutants

Double-layer protection extends the lifespan of the core filter material.

The pre-filtration layer of the first filter uses high-density polyester fiber to prioritize the interception of large particles such as hair and dust, reducing clogging of the subsequent HEPA layer. The H13 grade HEPA filter material has a filtration efficiency of 99.97%, capturing allergens such as PM2.5, pollen, and dust mites as small as 0.3 microns. The double-layer structure improves purification precision while extending the lifespan of the HEPA layer, balancing effectiveness and economy.

3. Second Filter: Coconut Shell Columnar Activated Carbon - Powerfully Adsorbs Odors and Harmful Gases

Premium coconut shell material, adsorption capacity twice that of ordinary activated carbon.

The activated carbon layer of the second filter uses columnar activated carbon made from premium coconut shells. Its well-developed porous structure and large adsorption capacity result in more than twice the adsorption effect compared to ordinary artificial activated carbon, powerfully adsorbing pollutants such as formaldehyde, benzene, TVOC, cooking fumes, and pet odors. The columnar shape prevents pulverization and maintains stable adsorption performance over a long period, resulting in longer-lasting purification in environments with strong odors.

4. Second Filter: Photocatalytic Filter - Decomposes Harmful Gases Without Secondary Pollution

Photocatalysis for More Thorough Purification

The photocatalytic layer of the second filter catalyzes the decomposition of harmful gases such as formaldehyde and benzene under light, converting them into harmless carbon dioxide and water. This forms a dual protection of "adsorption + decomposition" with the coconut shell columnar activated carbon, preventing secondary release after activated carbon saturation. It remains effective even under normal indoor lighting conditions, making air purification safer and more thorough.

5. HSP001 Dual-Piece Filter - High Compatibility + High Cost-Effectiveness

Easy Installation, Lower Replacement Costs

The HSP001 dual-piece filter is precisely calibrated to fit most mainstream air purifier models. No modification is required during installation; simply replace the filter for immediate use. Compared to single-piece composite filters, the dual-piece design allows for individual replacement of each layer based on its wear condition (e.g., replacing only the pre-filter + HEPA filter), further reducing long-term operating costs. It is a high-quality filter choice that balances purification performance and cost-effectiveness.
