In a compact unit the Alen T300 HEPA tower air purifier delivers style and performance. Unlike many other tower designs the Alen T300 is a true HEPA air purifier with advanced features such as a UV lamp for bacterial control and activated carbon filter for enhanced odor removal. The T300 has affordable replacement filters that are easy to change eliminating the need to come in contact with the very particles you want to avoid. With ionic-type tower units you come in contact with those particles with each cleaning. The T300 is a great choice for those who want a sleek design without sacrificing performance.
