Filter Replacement
Important note: The filters can be contaminated with various particles, including viable and
potentially infectious contaminants. Suppose it is suspected that filters could be contaminated with
contagious pollutants. In that case, it is recommended that before starting filter replacement, all
designated PPE devices must be available, in good condition, and used during filter replacement.
Please refer to local/federal regulations for PPE guidance. Similarly, handle dirty filters with extreme
caution and local/national guidelines.
To replace the pre-filters & HEPA filters, please proceed
according to the following steps:
1. Turn the dial switch located on the lower back of the unit
to the Off position. (Figure 1)
2. Disconnect the power cord from the wall receptacle
and wait for 15 seconds for electric discharge from the
internal components.
3. Remove the back panel, unlocking the back screws.
