 BOGO is back for one week only for the Eden Pure Thunderstorm Air Purifier. You've been waiting for it and now it's here. You've always wondered if the Thunderstorm Air Purifier works and this is the best time to find out. Eric, one listener wrote, we purchased two Thunderstorm Air Purifiers one year ago. We placed it in a damp cellar with stone walls. It did an amazing job. It got rid of the musty odor. We've ordered additional units to give to other family members. I highly recommend this product.
