Our mission is to maintain the purity of Missouri's air to protect the health, general welfare and property of the people. The Air Pollution Control Program has more than 6 million customers. Whether an urban citizen or someone far removed from other people, everyone who lives in Missouri needs and deserves clean air.

You can help clean the air and save some money in the process!

Install a programmable thermostat: Cooling and heating your home accounts for almost half of your energy bill – about $1,000 a year! One of the easiest ways you can save energy in your home and help reduce carbon pollution is by installing a programmable thermostat. For example:

  • Set your thermostat for 78 degrees during the summer (or 68 degrees during winter) when you are awake and at home.
  • Decide on at least an eight-hour period per day when you can set your thermostat 10 − 15 degrees warmer during the summer (or 10 − 15 degrees cooler during the winter).

Check your HVAC filter every month, particularly during winter and summer when you're frequently using the system. Change the filter if it looks dirty or every three months at a minimum. Dirty filters slow down the air flow making the system work harder to keep you cool or warm which then increases your energy bill.
