Verdict

The COSEMAR OZONO 7-in-1 digital home air purifier is a multi-stage disinfection system that combines a True HEPA filter, an activated carbon filter, a UV-C sterilisation lamp, an ioniser, and a 100 mg/h ozone generator to eliminate 99.9% of indoor allergens, smoke, dust, bacteria, and viruses. Key advantages include its versatility in addressing complex airborne pollutants, deep multi-layered filtration, and advanced chemical-free microbial destruction. However, the machine emits ozone gas as part of its decontamination process, meaning it should not be operated in occupied rooms due to potential respiratory irritation, and its complex multi-filter setup demands ongoing maintenance costs.
