                This filter blocks dust and airborne particles from the air. I no longer have as much dust as I did with previous (cheap) filter.

                      Comments about Koch Filter Corporation 14" X 18" X 1" MERV 11 Pleated Filter:

                      Bought these filters because I am allergic to most household allergens. Filter does a great job removing particles, from cat hair to dust, from the air. This is presumably a step down from their best filter, at a MERV 11 rather than 13, but it does the job just fine.

                        I am happy with the new upgraded filter. I have allergies and cats, so with this filter I can tell it does a better job than the low grade filter I was using. I would rather pay a little more for cleaner air.
