[2 in 1 Air Sanitization] Combining multi-functional design, our Air Sanitization Machine effectively eliminates odors from pets, smoke, toilets, and kitchens. [Negative Ion Generator] Featuring a built-in negative ion generator, our device produces anions that bond with positively charged dust, causing it to settle to the ground. This helps prevent the inhalation of particulates in the air, resulting in fresher air and improved sleep quality.
