Installing or Replacing the Filter
One of the filters must be in place at all times to operate the device. If a filter is not
already installed in the device, you must at least install the reusable filter before using
your device.
The device has an automatic air filter reminder. Every 30 days, your device will display a
message reminding you to check your filters and replace them as needed.
Note
The filter reminder is a message only. The device does not detect the performance
of the filters, nor does it recognize when a filter has been replaced.
Follow these steps to install/replace a filter into your device:
1. If replacing an existing filter, pull out the old filter assembly.
2. Insert a dry, reusable filter or a new, disposable, fine filter into the filter access on
the device.
