The cloud of ash spewed into the atmosphere
consists mainly of minerals of small particles and water vapor.
With ash from the Iceland
volcano still affecting air travel around the world, filter maker Camfil Farr is
advising caution.
Although it is too soon to know if areas outside of Europe will be impacted, company officials point
out that small particles that fly far from the eruption site could impact air quality
and health worldwide.
The company recommends that air filters with
minimum efficiency values of 13 or higher be used to keep particles out of
air-handling units. Also check the units more frequently and change any clogged
filters.
