    Damages on filter
  

*by M***G on Reviewed in the United States on August 19, 2018*

i got two filters loosely wrapped with no label of an Accumulair Diamond and no plastic film covers (filters are usually sold with plastic cover for preventing dust deposit). There are damages on top of left side on both filters. it is not functional as an air filter and i trash them. It is very disappointed experience and unreliable seller. I'm not buying again with this seller and products.
