Air Purifier Clean Air Optima CA-508 60 dB 240 m³/h Grey Silver
The Clean Air Optima CA-508 is a high-performance air purifier designed to improve indoor air quality in homes and professional spaces. Operating with a CADR-rated filtration system and certified performance, the unit removes a wide range of airborne pollutants including fine dust, pollen, smoke and biological particles. The CA-508 combines a TRUE HEPA filter with an activated carbon prefilter and antimicrobial PPT coating to retain particles down to 0.3 µm with a reported efficiency of 99.97%, while the device provides an airflow capacity of up to 240 m³/h and a rated noise level around 60 dB. The compact unit in grey and silver suits living rooms, offices and medically sensitive environments where clean air is required.
The purifier uses a TRUE HEPA filter with PPT (Pet Pure Treatment) antimicrobial coating and a large folded filter surface to minimise air resistance and maximise capture of submicroscopic particles. An activated carbon prefilter reduces gases, volatile organic compounds (VOCs), odors and cigarette smoke. The device is AHAM/CADR/CE certified, operates without producing ozone and is suitable for allergy sufferers. Together these technologies provide high retention of fine dust, pollen, spores, smoke, pet dander and common indoor odors.
Place the CA-508 on a stable, flat surface with sufficient clearance around the air inlet and outlet to allow unrestricted airflow. Connect to a suitable mains outlet and switch the unit on; select the appropriate fan speed according to room size and desired noise level. For optimal performance keep doors and windows closed while the purifier is running. Replace combination filters according to the manufacturer’s instructions or when indicator lights signal filter replacement to maintain filtration efficiency.
For best results, run the purifier continuously in rooms where air quality is a concern and choose a higher fan speed during activities that generate pollutants (cooking, renovation, smoking). Regularly vacuum and clean surrounding surfaces to reduce particle load and check the prefilter if visible dust accumulation occurs. Follow the manufacturer’s guidance for filter replacement intervals and safe disposal.
