Air Purifier/Ionizer Clean Air Optima CA-508 suitable for spaces up to 80 m². Its dual function will help clean the air in your space from any harmful particles. The device, functioning as an ionizer, cleans the air by electrically charging its molecules, thus creating negative ions. These, in turn, attract positively charged ions, including various bacteria, microbes, cigarette smoke, dust, and other allergens. As it is also an air purifier, it effectively filters the air in the room by passing it through the device's filters, which trap microorganisms and particles, and then releases the clean air back into the room.
