  • Damaged unusable fiters
I received these filters with a damaged box and damaged unusable filters. Why should I have to pay for the return.

  • Ordered "Platiinum MERV 13", received "Silver MERV 8"
We'll see what Filter Buy's customer service is like...I'm returning these. Every piece of information in my Amazon Prime order is clear, but, though prompt, they shipped me a far lesser quality product than the order claimed. I'm skeptical of the 100% 5 star rating.
