I placed an order in the beginning of May (2020). I ordered 4 face masks and replacement filters as well. About 4 weeks after placing the order and getting no updates on my order, I decided to contact the company, after which I received an automated email telling me that order numbers were through the roof and to have some patience. Well about a week or so after that, I received my order, or at least what they considered to be my order- not what I paid for. I received only 2 of the 4 masks I ordered, and about half of the replacement filters as well. I've attempted to reach out to the company since then, with only another automated email in return, telling me the same message as the first. The e-mail stated that my order "Should be shipping as soon as possible," even though, according to my order number, the order had already been shipped and delivered. I'm reviewing this 2 stars out of 5 (instead of only 1/5) only because I did receive a partial order.
