Review on VEVA HEPA and Carbon Filter Replacement Kit - 2 Pack HEPA Air Filters & 6 Carbon Pre-Filters - Fits Air Purifier Series AC5000, AC5250PT, AC5300B, AC5350W, AC5350B, CDAP5500B & AP2800CA by Erin Johnston

I just installed these so I'm not commenting on the quality of the filtration. However, I am a Quality Assurance Manager, so attention to detail is my job. Velcro has been placed correctly. The packaging was great. The charcoal filter was thick with charcoal (I've come across really weak charcoal filters). The filter housing is durable and fits snugly. The Hepa filter media seemed solid and when I exposed it to the air it smelled fresh. Overall I am happy with this purchase and have ordered more.
