## Description

Hessaire MC18V Portable Evaporative Cooler, Green, 1300 CFM, Cools 500 Square Feet

Review: I don't normally give five stars even for something I think is a great product at a good value. I reserve the fifth star for durability. Previous owners have testified to the durability. First the disclaimer. It is NOT air conditioning. You don't get that for under $200. It is an evaporative cooler. It passes air through a damp media and when the water evaporates it absorbs heat. It's not magic, it's physics. The more water that evaporates the more heat that is absorbed. Since water does not like to evaporate in high humidity situations this cooler loses its effectiveness as the humidity increases. If your normal relative humidity STARTS at 40% don't even think about using this cooler. Also, for the same reason, you don't want to try to use it in a closed room, not even a closet. As the cooler operates the evaporated water adds to the humidity so after a short time the room becomes so humid the cooler quits working. The air coming in the back needs to be 100% new, not recurculated. Back the cooler up to an open window and also turn on some bathroom or kitchen exhaust fans to encourage air to come in the open window. I only use mine outdoors. That's how they work. Here's why this one is so good. An evaporative cooler only needs water, a pump, a fan, cooling media and a switch to control it all. This one has a reservoir large enough that you can get several hours out of a full tank. It has a water pump that keeps the water circulating over the media no matter how much is consumed. The fan serves two purposes. It pulls air into the back through the cooling media and out the front to cooler the user. This fan is plenty large enough to do both. The real key to its success is the size of the media. It follows. The larger the surface area of the media, the more the water evaporates, the more water that evaporates the more air that is cooled. Evaporative coolers need to be big because they need their media to be big. When you see the little one cubic foot miracle coolers being sold they're a joke. The media and fan are far too small to be effective. And finally the controls. A single rotary switch with five positions. Hi/lo wet, hi/lo dry and pump only. Why pump only? For prepping the media before cooling but mostly for maintenance. The nasty thing about evaporative coolers is that when the water evaporates it leaves everything that was in the water behind. If you have very hard water your media could turn into a brick in a single season. Since bricks aren't absorbent they don't make good cooler pads. You can keep the mineral deposits under control by circulating acidic water over the pads periodically either vinegar or Limeaway depending on how bad it is. Drain the water after cleaning. The pump only position allows you to pour in your solution, turn on the pump and walk away. Come back later, drain and refill and you're good for weeks more use. If you have RO water, soft water or filtered water cleaning becomes less of an issue. Two features this cooler has that most don't that I'm utilizing is the float inlet and the analog switch. They give you a garden hose adapter so you can hook a hose to it, turn the water on a bit and the tank fills and stays full with no need for refilling. I did it with 1/4 inch irrigation tubing because it's much smaller and easier to keep out of the way. The switch is unique because it doesn't involve any electronics. You can plug the cooler into a smart plug and turn it on or off with a phone app or voice assistant. The cherry on top is that it's made to last so it's repairable with available replacement parts. Try that with ANY Chinese made products.
Review: Unless you can put it in front of a window or a source of dry air and have a door open on the other side of the room, it is just a big humidifier. It needs to work like a dairy barn. Fan pulls Outside air in though the pad and into the room. Only difference is the fan is on the other end of the dairy barn exhausting and pulling outside air through through the pad.not blowing into the barn. If it just circulated inside air though the pad it wouldn’t cool and if there was no exhaust it would be a soupy mess lol. If the air going thru the pad is not dry and it’s humid then there will be little to no evaporation occurring on the pad and thus no evaporative cooling effect If you’re in a dry place this will come in handy don’t need anything there just turn it on.

## Features

- EVAPORATIVE COOLING: HESSAIRE’s evaporative cooling fans are designed to pull hot, dry air through a water-soaked filter using a fan to decrease the ambient temperature. * It DOES NOT use refrigerants to remove heat like an air conditioner.
- INCREASE HUMIDITY IN DRY CLIMATES: The MC18V evaporative cooling fan is optimal when used in hot, dry climates to filter ambient air while increasing the moisture and delivering 1,300 CFM of cool airflow. *Not effective in high humidity areas.
- ENERGY EFFICENT & ECO FRIENDLY: Evaporative cooling fans save up to 50% on electricity compared to refrigerated air conditioning systems. Using water instead of refrigerant prevents any release of ozone depleting chemicals into the air.
- MANUAL & CONTINUOUS WATER FILL: Hessaire’s MC18V has a 4.8-gallon water tank creating up to 3-4 hours of use. The built-in float valve and garden hose adapter allow for easy connection and continuous water flow without overflowing your tank.
- EASY TO OPERATE & SIMPLE TO MAINTAIN: Fill tank, connect power, place unit in a well-ventilated area, flip the switch, and you're all set. Before storing, run for 30 minutes on fan to dry the filter, to prevent future mildew.

## Questions & Answers

**Q: We are in a very dry climate. no humidity. i want to use indoors mainly.  why do i need to keep a window open? is it dangerous not to?**
A: The ability of a swamp cooler to cool air is entirely dependent upon the incoming air being dry (in the wet-bulb sense.)
Essentially, once the air is too wet, it won't take up any more heat.  A swamp cooler of this size can saturate the air in a 500 sqft of area in just a few hours, and then it will no longer cool THAT air if it is going in the back.  So, it will work best if you put the swamp cooler in an open door or window (or otherwise dry area) to ensure air going into the back is always dry.  
It's not dangerous to not open a door or window.  It just literally won't do anything but be a big expensive fan.  I would recommend getting a coupld of small thermometer/hydrometers to monitor your situation along with this.  There are cheap LCD ones available here on Amazon.  Put one on the back of the unit to monitor the air going into it, and one in the area you intend to cool to make sure humidity doesn't get high.

**Q: How do you get rid of the smell when just out of the box and turned on for the first time?**
A: Did you put water in it? Mine didnt have a smell

**Q: How many inches are the caster wheels?**
A: 2” or so

**Q: Will it use regular water or does it need distilled water? Is distilled water better for it? Thanks**
A: Regular water works just fine that's what I use but the only downfall to using regular water here in Arizona is because it's hard water the back of the item turns white from all the calcium in the hard water which means you have to clean it more often so to answer your question you definitely should use distilled water anything is better than tap water from Arizona

As usual, most of the so called high end stuff I buy that's made overseas is useless. As you can see from the pictures the pump does not appropriately pump water where needed. I had set this up in my garage gym for my afternoon workout, I'm close to Palm Springs so it's dry heat, and water coolers typically work just fine. But not this one! 109 in the garage / gym area, and this did pretty much nothing. I would not recommend this to anyone wanting to stay cool, but if you like to have an expensive fan that masquerades as a cooler, by all means this is for you!
