AirFanta Wear/mini Replacement Filters (Set of 4)

Yes. Testing from an independent laboratory showed that AirFanta Wear (standard: GB/T 18801-2022, test report: KJ2025002910E) captured over 99.99% of the Human Coronavirus HCoV-229E.

As for SARS-Cov2 (COVID-19), based on findings from multiple studies, there is strong evidence that the virus resides in exhaled aerosols in the 1 to 5 micron size range. AirFanta’s high efficiency filters can remove 99.4% to 100% of viral aerosols in this range in a single pass.

Our findings from both H1N1 and SARS-Cov2 (COVID-19) should also apply to other kinds of airborne viruses as well, as the size of viral aerosols exhaled from an infectious person doesn’t change much regardless of the type of virus.

Yes, it can filter allergens, so it should be able to reduce allergy symptoms (due to less allergens being breathed in) when the device is used according to the instructions.

Testing from an independent laboratory showed that AirFanta Wear (standard: GB/T 18801-2022, test report: KJ2025003186E) captured 99.97% of pine pollen at PM2.5 size.

You should replace the filter every 150 to 200 hours of use. The filter lifespan largely depends on environmental conditions. For example, you may need to replace it more often when using it under environmental conditions such as haze or wildfire smoke. Visually inspect the condition of the filter (if it looks black or appears to be full of dust, it should be replaced!) if you are unsure. Filtration efficiency and overall protection will be reduced when a dirty filter is not replaced.
