Air Purifier for Asthma
For asthma sufferers, indoor air quality is a daily health issue — dust mites, pollen, mold spores and PM2.5 all trigger attacks. True HEPA H13 filtration removes 99.95% of these triggers from the air. The Corsi-Rosenthal kit from Clean Air Kits delivers CADR 369–550 m³/h, proven by HouseFresh to outperform Dyson and Philips. NHS-compatible, CE certified. From £144 with free UK shipping.
At Clean Air Kits, we've developed premium DIY air purifier kits based on the proven Corsi-Rosenthal Box design. Our kits are Energy Star 2026 certified and independently tested to be 2.4x more efficient than commercial alternatives like Dyson.
