Uprights remove larger particles from your home but do not remove all of the smaller particles. A NuTone Central Vacuum has five times the cleaning power of an upright vacuum to pick up all of the particles and remove them from your home. Uprights use systems that re-circulate particles back into the air, some of which are deposited back into your home. Air pollutants in the home can be a major contributor to health issues such as asthma, fatigue, itchy eyes, and even sleeping problems. Nasal, non-nasal, eye and sleep symptoms were all reduced between 49% to 60% with the use of a central vacuum system.
