Filters were as good as advertised. No unpleasant surprises.Took out the old ones and slipped in the new ones.I have 2 furnaces. The entire job was completed in one minute.
I saw these filters on a tv review show. I could see that the framework of the filter was rigid and appeared sturdy. I quickly received my order. Unlike my previous filters, these fit well and are priced competitively. Good product!
