Warning! Do not attempt to clean filters. Attempted cleaning can

damage filters and cause potential risk to health and equipment.

Note: OK International recommends replacement of filters annually as a

minimum. Use only original replacement filters.

Model BVX-203

This model features a deep-bed gas filter, which generally does not clog and

reduce airflow as common with HEPA filters. Replace both filters; pre-filter and

carbon filter as soon as odors become noticeable.

Note: Replace filters at least every 6 months, as most gas-phase filter media

achieve saturation by adsorbing moisture from ambient air. Use only original

replacement filters.

5.3 Safety Interlock

The safety switch is an interlock which turns off the fan when the main filter is

removed and when the fan inlet opening is exposed. The safety switch also

prevents the system from operating without filters which would allow impurities

to contaminate the internal unit.

WARNING! Do not bypass safety interlock. Bypassing safety interlock could

result in injury to persons.
