it's helpful to know what country you are in. here in the states, accessed through dyson.com, the electrostatic filters are available.
someone not in the US asked this question a few months ago as they were seeing the same thing ( out of stock).
the face covering and ffp2 community options are out of stock on the US site as well.
as you may know, these headphones did not sell well and dyson are obviously not promoting the filtration feature as they used to. it may be weeks/months when these items are available. if you see the “notify me” option on the item you want, i suggest you enter your email to find out whern they are in stock.
i have both headphones and love the zones. had them since launch day.
