I’m impressed! The customer service is outstanding. I placed an order for what I thought were the correct air filters for my furnance. Shortly afterwards, I received a call questioning my order and sure enough, I was completely wrong. The salesperson got me straightened out (how did she know?). I had my filters the next day! I will also comment on the cost. Previously I purchased from my repair person during my semiannual inspection, $48 each. From Nebraska Air Filter Inc, I purchased 6 for $125! … I will certainly be back and will let everyone know about this place. It’s refreshing to find a company like this these days.
