Take them down one by one. For each, lift up on the front and then turn your hand
left then right to break the back edge free from the filter. Once you have the back
of the fan free, you can pull it towards you until you are able to grab it with your
other hand.
Once you have it with both hands either hand it to someone else standing nearby
or be very careful and step down the ladder.

Take down your old primary filters and put in a stack near the hood (as you will

or be very careful and step down the ladder.
At this time, it is strongly recommended that you inspect your lights and pre-
filters since this is a convenient time to replace your pre-filters and swap out any
bad or suspect bulbs.
