We Need New Air Filter

I cannot believe when I saw our electric bill yesterday, it went up twice as what we normally pay per month. This is one of the reasons why I don’t like winter, I tried all my best not to use too much electricity including our heater and furnace but still it doesn’t help. I talked to my husband this morning to get a new Filters Fast air filter to maybe help lower our electricity bill because the one that we had right now is not working well. We close the air filter in both rooms that has not been used but the air is still coming out, that might be the reason why our electric bill still going up. Anyway, I found some online and I am going to place my order the first thing in the morning.
