Nordic Pure 20x25x1 MERV 12 Pleated AC Furnace Air Filters, 6 PACK, 6 Count – Amazon Prime – $27.95

Ran out of Air Filters today and went to re-order. Noticed that the price was crazy low since the last order I did for a 6 pack was $47.35. Lowest price via Camel 3x. 3 pack is $35.84 6 pack 27.95 12 pack 81.62 Ordering 3x 6-pack ends up being $83.85 before tax. Which gives you 18 Air Filters for close to the price of a 12-pack. https://www.amazon.com/dp/B004QL7...jEb1GCN528
