Our page is about air filters and heating and cooling homes. We learned a lot from our research. We learned that we you should change your air filters every three months especially when it's heavy seasons (summers and winters). We also learned that it doesn't cost a lot if you buy a new air filter, it will only cost $10-$15. We learned that you are supposed to wear a sweater and pants if you are cold in your house ( it will save you money). When you turn down your thermostat you can save 3% per degree. If you have a $100 bill every degree that you turn down your thermostat you will save 3 dollars.
* Change your air filter every three months * Wear heavy clothes during cold seasons * It costs $10-$15 to change your air filter * You can save $2-$5 for every degree you turn down your thermostat |
Problem- Why do you need to change your air filter? Hypothesis- A dirty filter will not let as much air through as a clean filter. Example- 1.Test the breathability of a old air filter. 2.Test the breathability of an new filter. 
Conclusion- Our hypothesis was correct. We learned that clean air filters works better than a dirty air filter. This saves money because your furnace does not have to work harder.
