If you want to shot videos with your Air 3 drone, and have them appear natural (or at least as natural as our movie-trained eyes allow), you need to use neutral density filters. I won’t explain the exposure triangle but if you don’t understand the relationship between aperture, shutter speed and ISO, you should learn this before using these filters.

These filters are designed for the DJI Air 3 and, as far as I know, only for that drone. They install on the drone with a twist, although it would have been nice if the manufacturer had included an instruction on how to mount and dismount the filters. I tested the density of the filters to insure they were 3, 4, 5 and 6 stops darker, and they were on the button. I also tested whether they were neutral density and found a slight shift to the red of about O.1 %. I regularly find this kind of a shift in even the best neutral density filters, so I was not concerned by it. If you are concerned than you probably know how to adjust for that in Lightroom Classic. Most videographers and photographers will be more than happy with the neutral nature of these filters.

I am unable to comment on the polarizing features of these filters. All of them bear the PL initials, but unlike most circular polarizers, these polarizers are not adjustable. In any event, I have found polarizers almost impossible to use with drones, whose relationship with the sun changes often, and in any event, is impossible to adjust while a drone is in flight. I don’t see a plus side to any polarizing features, but I don’t see a down side either.

I am using these filters with my Air 3 when I shoot videos and am happy with them.
