Even though an outdoor clothesline is the most energy-efficient way to dry laundry, a dryer is a necessity for many people. To maximize the efficiency of your dryer, try locating the machine in a warm room rather than a cold basement; when warmer air goes into the dryer, it needs less energy to heat up. Also, separate clothing based on drying times; heavy, damp towels should be dried separately from quick-drying fabrics. Also, avoid drying items like nylon and athletic wear; they can shrink in the dryer and they dry quickly when hung.

If you use an outdoor fire pit, you use wood as your source of fuel to get it roaring. But not all wood is the same, and you should avoid pressure-treated wood. This is lumber that's designed for construction -- railroad ties, decking, shipping pallets –- and it is treated with chemicals to prevent rotting. Those chemicals are released when this wood is burned, and they can be dangerous. If you have some leftover untreated plywood, it's fine to burn. But when in doubt, don't take the risk. Also, avoid burning cardboard: It can create huge, smoldering "flakes" that can travel and ignite fires.

Air filters are critical for your HVAC system to keep things like allergens and dust/dirt particles from blowing around your home. The filters work, but they need to be replaced when they get too dirty. And a dirty filter can reduce airflow, which forces your HVAC system to work extra hard. Since filters need to be replaced on a regular basis and can be easily forgotten, consider signing up for a subscription service to have filters automatically sent to you when you need to replace your old ones.
