Comments about Koch Filter Corporation 12" X 12" X 1" MERV 11 Pleated Filter:
I read some comments that the true size is a bit smaller than 12x12. I felt this allowed the filters to fit in the opening better. Seems like a very good product for a great price.

Comments about Koch Filter Corporation 12" X 12" X 1" MERV 11 Pleated Filter:
Even though you're ordering 12" x 12", the filters you receive are actually labeled as 11.5" x 11.5" I'm guessing someone decided it would allow an additional filter to be produced if they used 0.25 sq. inches less material per product. Their "Quality Filters" brand 20" x 20" MERV 11 Kimberly Clark filters are actually the correct size so feel free to try other sizes since they may be a perfect fit. Also, these don't seem flow as well as the 3M Filtrete products I have been using-- causing a noticeable increase in noise and a difference in pressure within the HVAC system (try to pull one off while the blower is running and it's a lot more difficult) Filter-outlet shipped them quickly, but they were loose inside the cardboard box and not wrapped in anything. I assumed a package of six would be in a package, now I'm storing them inside a plastic trash bag until I use them.

Comments about Koch Filter Corporation 12" X 12" X 1" MERV 11 Pleated Filter:
This filter size is impossible to find at local warehouse building retailers. IAQ always has it available. I was skeptical about the claim that a MERV 11 filter would make a big difference for our indoor air quality. However, this is my second year using them and I have noticed a huge difference. In our older home (> 75 years old) the filters last about 2 months, though some newer homes may get even longer service. If you have family members with allergy problems, a MERV 11 filter like this one is a must.
Service and delivery comments:
Shipping EXCEEDED expectations as it always does from IAQ
