Iq Air Pro 250. A couple years old from USA. Includes transformer that is higher voltage than the air purifier so it can easily run it safely. Filters were vacuumed and cleaned weekly. Has only the Pro-Max filter and Hyper HEPA filter, both still have a long life. The V5-Cell is only used for odors and gasses so I never saw a need for it. sell: 4000 ONO pickup: Andingmen
