I recently purchased a PureZone Elite 4-In-1 True Hepa Air Purifier . . . What a difference it has made in my home!! It has been used in the living room, & master bedroom . . . Quiet, & does not take up a lot of space!! A much needed product for those who suffer from various allergies . . . Pure Enrichment, & their PureZone Elite Air Purifier does not disappoint!!
