While the Starfield base game doesn’t allow you to craft the O2 Filter mod, or unequip it from any Helmets that have it, you can potentially grind the Starfield loot tables to get it on the Helmet you want.
In the case of weapons, the easiest method is to use our Starfield legendary weapons farm exploit.
For armor, refreshing vendor inventories by waiting several in-game days seems the best way to cycle through the available options, though unfortunately this is a much slower method. Should a Starfield mod or exploit be discovered, we’ll include the method here.
