This purifier is great for those who have small children who have tons of allergies. It’s design es great and not big whatsoever. The way that it works is super easy that even kids can turn it on , it has a button on top that turns it on and it automatically starts looking  checking your air quality. Once the purifier knows what your air percentage is it starts making its magic. It is super quiet that you don’t even hear it when it is on. The best part is not only does it help to provide clean fresh air but it also helps get rid of  COVID germs.
