FAN WITH HEPA FILTER: The HEPA (H11 grade) filter filtrates over 98% of particulate matter of 0.3 micron, 99.4% of 1 micrion and 100% of 5 micron. It is designed to be held close to and over (covering) your nose to avoid breathing unfiltered air.
BREEZE: Due to the resistance of the HEPA filter, the airflow is not as noticeable as other fans without filters. Therefore this product is not to be used for cooling purposes, but to provide clean and filtered air. Despite the low airflow, the fan filters 150 Litres of air per min, which is sufficient for you to breathe in clean air, when used appropriately.
RECHARGEABLE BATTERY: The product uses two rechargeable 3200mAh batteries, providing up to 10 hours usage on a single charge. The batteries are chargeable via a USB-C port.
REPLACEMENT FILTERS: The device comes with a pre-installed filter inside and one piece of replacement also. It is recommended to replace it every month. More replacement filters can be found on Amazon under the brand AirFanta.
