This Air Purifier is not for spaces larger than a closet or very small room. I purchased three of these Air Purifiers and they do work. I found I was needing to recharge each one several times a day, the batteries do not hold charge well. These are definitely not something you'd want to purchase if you need them for larger areas of the home and do not want the hassle of recharging each one a few times each day. This product does have room for improvement and could certainly be a very profitable product. If the battery charge lasted longer, they would be wonderful for what I needed them for but otherwise, they just are not ideal nor convenient.
