PARAMETER

STANDARD N-95 (P-2)

MICRO100™

Filtration of particles

95% (94%)

Tested for: Filtration of 99% of particles >0.1 micron

Filtration of microorganisms

Not tested

Tested for: Filtration of 99.9% of microorganisms including Viruses

Range of protection assuming that avian flu will spread from birds to humans (*)

From contamination by aspiration and digestion

Besides the respiratory orifices the hood protects eyes, ears, bare skin of head and neck(**)

Fitting

Half face masks do not fit all face types, resulting in potential leakage of contaminated air 

Hood accommodates all types of head shapes, including special features like mustache or beard and completely seals the space inside the hood so that all the inhaled air enters only through the filter
Verbal communication is possible, including use of telephone

Protecting the eyes

Half face masks do not protect the eyes

Hood protects the eyes and also allows wearing of glasses if needed

Economical concept in the relevant context

"Level A" protection would be optimal but its high cost would dictate multiple use, leading to potential Cross Infection

Minimal but adequate protection at relatively low cost enables  adopting the concept of using a disposable device, thereby isolating contaminants

Duration of use

"Level A": about 30 minutes

Not limited by time of use, can be used until clogged

Ability to drink water during work (essential to avoid dehydration if workers are wearing isolated garments)

Half face mask does not permit drinking of water while in contaminated areas

Hood type masks permit safe drinking via a tube connected to a filtered,  protected water bottle

Disposal

Eventually contaminated mask needs special disposal solution

Used hood should be removed by turning it outside-in, to accommodate the used gloves and garments and to be sealed by the rubber bands, thereby not presenting immediate hazard regarding disposal
