The MERV rating of a filter sets its cost. On average, a 4-inch filter’s price is $55, whereas the cost of a 1-inch filter is $20. In other words, a high MERV will cost you more than a low MERV. Undoubtedly, the 1-inch furnace filter will cost you less initially. However, you will have the filter changed at least once a month.
