In China, many migrant workers in big cities live in bad condition housing with limited spaces.The average space for a person or a family is about 6.4 square meters .This is including a bed room, a kitchen and a toilet . Our idea is to create a shared air cleaner designed for narrow spaces. We can offer to lease to these migrant workers with low budget and help them guard clear air even in such limited space.The Shared air cleaner is made by reasonable and economical materials. Just sign up your Haier service membership, and all shipping and filter change service can be completed in one step.
