Purify the Air

My brother bought for my sister-in-law one of those electric stone air purifier things which you plug into a power point and when it is lit up, it is supposed to purify the air around us to improve our health in general and to help certain ailments for Christmas. air purifiers like these are now quite common in homes of people who believe in natural healing. Well, in my opinion as long as it helps clean the air, it is good.
