Lab Study in Europe Concludes Central Vacuum Systems Effective for Those Suffering from Pet Allergies

I found an extremely interesting study, with conclusions that are important for individuals suffering from pet allergies. A laboratory researched ways to reduce allergens produced by mice kept in cages. There were several conclusions, but for those with pets in the home the following quote is extremely important:

"Traditionally floor cleaning has been carried out by dry sweeping or by using a portable vacuum cleaner. Portable vacuum cleaners without high-efficiency particulate air filtration on the exhaust may contribute to airborne dust by leakage through the filter. Portable vacuum cleaners may also contribute to airborne dust by disturbance of floor dust.To minimize the spread of allergens, floors are first cleaned using a centralized vacuum cleaner that delivers dust into a closed pipe conveyor with deposition into a closed container. After vacuuming, floors are wiped using a moist mop."
