It used to be that people who cared about the environment were looked down upon. People called them derogatory names like tree hugger, eagle freaks and greenies. Nowadays, it's considered a smart thing to care about the world we all share and the air we all breathe. We also care about keeping cool on a warm day. How do we merge these two? Evaporative air coolers.
Evaporative air Coolers like the Swamp Cooler are coolers that use the cooling effect of water evaporation to lower air temperature. Think about when you've just exerted your body by playing a sport or running to catch some sort of public transportation. You feel hot, sweaty and out of breath. Once your sweat evaporates, you feel cooler though. That is the idea behind evaporative cooling.
Evaporative coolers use 75% less energy than air conditioners. That's not the only way they are good for the environment though. They don't use refrigerants like freon. Freon destroys the ozone layer. They also curb noise pollution by using a blower instead of an axial fan like an air conditioner.
Some people would think that with less energy and without freon, evaporative coolers aren't that powerful, but they can cool up to 350 square feet. They also help maintain the durability and lifespan of furniture by keeping furniture and fabric moisturized. Evaporative coolers also channel fresh air into the area they are cooling. As well as the hot air in the area being pushed out by the cool air through evaporation, bad odor, dust and smoke are also eliminated. Air circulation occurs every two to three minutes giving you a continuous supply of fresh air. The risk of bacteria being trapped in the air is also reduced. The moisture pad also acts as a filter which helps trap dust.
Evaporative coolers are also easy to take care of. They have refillable water tanks. Each refill should last up to ten hours. Sometimes they can have a hose connection which will continuously supply fresh water to the cooler. The filters in evaporative coolers can often be removed and rinsed.
