To make your vacuuming time productive and as green as possible, I suggest a bagless brand that uses a HEPA filter. HEPA is an acronym for “high efficiency particulate air.” The HEPA filter can trap a large amount of very small particles that other vacuum cleaners would simply recirculate back into the air of your home. Some believe that these types of filters are essential for anyone with airborne allergies and for all those wanting to reduce the sources of common air pollution in the home. Vacuums with HEPA filters are available from such major manufacturers as Bissell, Miele, Eureka Sanitaire, Electrolux, Sebo, and EIO.
