I have a high school project to do

My family and I live in the south, where the weather conditions is consistently moderate and actually humid, but the people I was with and I constantly worry about cooling our home. The Summer rapidly decreasing temperatures are usually in the 90s, with a few afternoons in the triple digits as well, then our A/C works well, however the humidity makes things more difficult. Our A/C can only cool the air! It cannot remove any excess humidity, however when the humidity levels are high, our condo doesn’t think cool and comfortable love it should, then my family and I noticed some problems with humidity in the bedroom. The people I was with and I even noticed some mold forming under the sink. My friends suggested  purchasing a dehumidifier to help remove extra humidity from our home. My fiance and I went to the hardware store to search for a dehumidifier. The people I was with and I found several or numerous dehumidifiers in our price range. My fiance and I chose a nice portable dehumidifier that has a reservoir; As it pulls excess humidity out of the air, the moisture builds up in a tank. The reservoir tank needs to be emptied every other afternoon, in order to keep the dehumidifier working well, then ever since the people I was with and I added the dehumidifier, the indoor air quality has been phenomenal. With less moisture in the air, our indoor air quality feels much more cool and crisp. Even my dust sensitivities are better. My fiance has been sleeping better, and she doesn’t wake up in the middle of the night with a headache anymore. I haven’t noticed any up-to-date mold growth under the sink either. I’m honestly impressed with the function of this small machine.
