use a cloth dampened with water and mild soap and allow
it to dry. Dispose of cloth in an appropriate container.
6. Inspect filters for wear, tears or other damage.

WaRnInG: If there is any doubt on the condition of the
filters, they MUST be replaced. DO NOT continue use if
filters are damaged. Class H filters should not get cleaned
manually outside of the unit.

WARNING: Never use compressed air or a brush to clean
filters, otherwise damage to the filter membrane will occur
which will allow dust to pass through the filter. If needed,
gently tap against a hard surface or rinse with room
temperature water and let air dry. Cleaning of the filters
is typically unnecessary, even if the filter is covered with
dust. The automatic filter cleaning system will maintain
maximum performance and continue to function. If visual
damage to the filter membrane exists, replace filters. Filters
typically last between six and twelve months depending
