Process of obtaining filters typically required driving to local hardware conglomerate, it included exorbitant prices filtration prices that rate lower than the MERV rated filters I received. The fact is this big box store not only gauges you in price they also murky the experience by using products they sell that makes use of a unrecognized rating system. As long as this is around Im not going back. Great experience thus far, ordered 1 year of filters and utilizing subscription service annually should be receiving resupply when due
