Their HVAC filters are very restrictive… Their HVAC filters are very restrictive and cause your system to work harder plus you can buy reusable filters at the big home improvement stores for a lot less. Their customer service sucks too.

I had had good service in the past but when… I had had good service in the past when I ordered masks. However, recently, I started an order, but had neglected to keep my password. When I followed the instructions to create a new password, I never received an email to reset the password, even after waiting the "at least 10 minute" period they recommended. I tried this multiple times over about 5 days. Because I have an account with them, I cannot get an order sent because I haven't received the email to reset my password. I checked my junk mail and it never came through there either.

Filti Masks Sadly, this could have been a 5 star review. I first ordered the sheet of face mask material and was pleased with that. Then they actually started offering fully made masks, which I also ordered. The nose piece on the mask are a joke. They are barely stronger that a cheap twist tie! Which really defeats the purpose of have such great filtering material

Good nanofiber cloth. I don't know whats up with the negative reviews. My order arrived as expected and ahead of schedule

I placed an order for material on… I placed an order for material on 3-28-20. Filti acknowledged receipt of my order on 4-1-20, after charging my credit card on 3-30-20. If you call their number, they ask you to leave a voicemail message with your phone number and e-mail address. Why? They don't return calls or emails. It is now one month later. I have received NO material, NO contact from Filti regarding an estimated ship date or anything. I understand things are running behind due to the situation, but a simple email with an estimated ship date would be nice. To date, I have made over 600 cotton face masks WITHOUT this product. I am initiating a dispute of this charge with my credit card company. Not good business.
