The seal on this packaging is terrible - super easy to break into especially at the stores so you need to be careful that you are not purchasing/receiving something that has the broken seal. Hard to tell at first glance, but I noticed that the one I received had a broken seal. Confirmed that it was used when I opened it and the filters were missing. The Nasal suction cup was visibly dirty too.
Hydrasense is an amazing product, especially for little toddlers, but they need to do better with the safety seals on this. Especially during a time line now where it is difficult to find on shelves/pandemic germs etc. I have seen far too many sitting on shelves opened and it is such a waste.
