Review on 🔍 Maximizing Filtration with Activated Filter Insert: Effective Non Woven Technology by Ikki Martini

For starters, ALL 30 filters were boxed in two groups of 15 and sealed. I bought these to fit in our filter sleeve on our current sheet masks and they cover our nose and mouth well. They are not bulky and I did a candle blow out test with excellent results. I would highly recommend them and plan to purchase more as the need arises. Fun fact: I have a big head 😂 which is always a factor when buying these things 😉
