FLUX Pre-filter 4x replacement Beam Air

These are the replacement Pre-filters for your Beam Air.

They are packaged per 4. 

They need to be replaced every 10-30 hours.

Don't forget to replace the other filters in time:

Pre-Filter (10-30 hours)
Medium efficiency filter (50-150 hours)
H13 HEPA filter (100-200 hours)
Charcoal filter (300-600 hours)
Remove the filters: 

Just open the top cover of the filter and remove the box from the inside. Then take out the Pre-filter and pull on the lids on each side of the Medium efficiency filter, put this aside and repeat the same steps with the charcoal filter. The box that's left is the H13 HEPA filter.

Replace only what is necessary.
