The New Edition features the most powerful fan ever used in a residential room air purifier. And that power translates into even better air cleaning results. The new three-dimensionally optimized design now uses state-of-the-art aerodynamics to convert energy into more air and less noise. And by improving further on the HyperHEPA filter pleating design, we were able to increase loading capacity up to 38%. This translates into higher airflow while increasing filter life – and this higher efficiency also saves you money by lowering filter replacement costs.
