You can get extra filters cheaply.
I would note that during the 2020 pandemic, it was not easy to get replacement filters. I recall that in April 2020 replacement filters were hard to get on less than a 2-3 month lead time.
Definitely! Storing replacement filters in addition to the masks themselves seems good.
