What is Hypoallergenic vacuum cleaner?

A hypoallergenic vacuum cleaner is a vacuum cleaner with filters designed to retain the vast majority of particles within the vacuum system.If successful this retention would greatly reduce the amount of potential allergens in the environment in which it is used.Regular vacuum cleaners are unable to retain most very fine dust and many allergens which simply are too small for the system to trap and are released from the system along with the exhaust air.

However, studies have shown that even vacuum cleaners featuring HEPA filters tend to release a large amount of allergens back into the air in the exhaust.In general, more recent and more expensive models do perform better than older and less expensive ones.
