Hopefully this is an other filters topic. Where do y'all get your furnace filters at? The HVAC tech that looked our furnace over today charged me $6 for a MERV 10. I thought that was a great deal! The big box and home stores are $10+ for anything MERV 10 or higher. I've seen some online places for close to $6. Anyone use the online stores and have good luck? Any had awful luck? Given the 3 oil filters I tried buying from Amazon had dented cans I'm hesitant to buy crushed and destroyed furnace filters online. Maybe I just call the HVAC place and ask if I can get 10 for $60?
