The filter has excellent sealing performance to prevent the leakage of experimental gases and is compatible with small laboratory air purifiers. Its lifespan can reach 2-4 months depending on the usage environment, effectively protecting the respiratory health of laboratory personnel.

4.High-density pre-filter, made of 500g/㎡ polyester fiber material, 30% denser than ordinary pre-filters. It can filter hair, cotton fluff, and large dust particles, protecting the HEPA filter from clogging and extending the overall filter core's lifespan. It is washable, and the filtration efficiency remains unchanged after cleaning. Compatible with the pre-filter layer of various purifiers, it can be replaced separately at a low cost, making it a "durable pre-filter guardian" for household purifiers.
