Review on 🌬️ Allergen Defense Furnace Filter by Filtrete by Chris Russell

Just someone wasn't paying attention. This was a pack of four filters from Amazon's stock range which I use often because you can often save money. This time one of the filters was apparently hacked to match the previous buyer's device (see picture) and then sent back. What really worries me is that someone should have checked this package before sending it to me. The other three were perfect with no issues. The product is great but the cut one is useless. I feel a little cheated because I can't return it because I needed one of the filters and I used one of the three good ones.
