If the daytime highs at your location are below 40ºF for the week consider getting a 96 hour UniHeat® pack to keep your filters warm. The filters do well as long as the daytime highs remain above freezing but they may enter a state of dormancy. They will take a little longer to wake up.
If the daytime highs are below freezing for the week, I recommend waiting to order filters when the temperature rises.
