What is the filtration efficiency of the HEPA filter?

Each filter meets the H13 grade standard, with a filtration efficiency of over 99.97% for 0.3 micron (μm) suspended particles, effectively blocking PM2.5, smoke, bacteria, and allergens.

How often does the HEPA filter need to be replaced?

Depending on the air quality of the usage environment and the frequency of use, it is generally recommended to replace it every 6 to 12 months. When the filter turns black or the purifier prompts for replacement, please replace it immediately to maintain performance.

Can HEPA filters be washed with water?

No. High-efficiency HEPA filters are interwoven with special fibers. Washing with water will destroy their electrostatic adsorption structure and fiber arrangement, leading to a significant drop in filtration efficiency. Please replace with a new one directly.
