Recent studies have linked air pollution to serious skin conditions like eczema, psoriasis and atopic dermatitis. According to estimates from the EPA (Environmental Protection Agency), the air inside an average home may be as much as five times more polluted than the air outdoors. Many dermatologists and skin experts agree that using a good air purifier can help significantly reduce the amount of pollutants in your home, which reduces air pollution exposures and minimizes skin condition triggers.
