USB desktop air purifier (portable): removes cigarette smoke from the office with HEPA filter, providing air

Filtration technology: Usually relies on a multi-stage filtration system, including a very important HEPA filter. The HEPA filter can capture 99.97% of airborne particles up to 0.3 microns in size, including small particles found in cigarette smoke. Additionally, activated carbon filter is often included. The porous structure of activated carbon can absorb volatile organic compounds in cigarette smoke, such as nicotine and tar, effectively removing odors. Air circulation system: Powered by a brushless - lower direct current motor, forming a strong air duct system. This system absorbs cigarette smoke present in the air through the inlet and causes the air to pass through the HEPA filter and activated carbon filter for purification. Then, the clean air is discharged through the outlet, thus achieving air circulation and purification in the office environment.
