The Airpura I700-W+ is identical to the I700-W unit except for an upgrade to the HEPA filter. The I700-W+ is configured with metal end caps on the large HEPA filter. This upgrade will be important to those who are chemically sensitive.
The Airpura I700-W+ has been specially designed to clean air of particulates. The extra large hospital HEPA filter has over 100 square feet of filtration surface. This is two and a half times the amount found even in the other Airpura models, and much, much more than found in typical consumer-oriented air cleaning machines. The I700-W+ is a good choice for use in medical situation as well as any environment with a heavier than typical particle load.
As with all Airpura units, the I700-W+ can be upgraded with germicidal UV bulbs. The optional 20 watt, 17 inch germicidal U-shaped lamp is recommended for abatement of pathogens such as viruses and bacteria that are frequently of concern in healthcare settings.
Because its main focus is on particulates, nearly all of the available space is used for HEPA filtration. If the ability to remove some odors is needed, this unit can be upgraded with the addition of the Hi-C carbon weave filter.
The fan moves 635 cubic feet of air per minute through these filters, cleaning up to 2,000 square feet. In a smaller space, the Airpura I700-W+ will provide more air exchanges per hour which will result in even cleaner air.
