This answer is a fairly quick one, but it also requires some consideration for your product and your specific circumstances. Foam Pump (KEXON) containers are actually not the only type of containers that can be sterilized. The sterilization process can also be a good fit for some plastic containers.
It might sound like a good idea to use finely filtered air as a "pure" agent to remove contaminants, but we would never recommend it. Filtered air just doesn't do a good job of removing fine particles. It also does not remove and release agents from the surfaces of Foam Pump.
Instead, you can count on methods like chemicals, dry heat, or steam, to remove contaminants. These methods work because they destroy, displace, and alter contaminants' physical properties so they release. You can then have impurities successfully removed and mitigate the risk to consumers.
