The re-usable face mask needs to be washed after each use. We recommend that you purchase 3-7 masks, so you can change your mask daily and wash 1-2 times per week. If you're not keen on washing regularly, you could have disposable face masks to offset the re-usable face mask.
1 week of usage could look like this:
Day 1 Re-usable face mask
Day2 Re-usable face mask
Day 3 Re-usable face mask
Day 4 Disposable face mask
Day 5 Re-usable face mask
Day 6 Re-usable face mask
Day 7 Disposable face mask (wash all your re-usable face masks you used through the week)
