Hessaire MC18V Portable Evaporative Air Cooler for Optimal Comfort

Conrad Kanno: This is a great supplement to your air conditioner, especially if you only have a window unit. This will help circulate air throughout your entire place. But, if you want to use the evaporative cooler, it only works for one summer. This is true especially if you use it constantly and live in a hot location, for example, above a non-insulated garage. After one summer, this stopped working as anything else than a fan. I still use it as a fan, and it works well, but it does not work as advertised. Unfortunately, I have not found a better alternative. Also, every other evaporative cooler seems to die quickly after heavy use, according to reviews I've seen. Sadly enough, this may be the best of the bunch.

Lou Costello: I have the cooler located in a well covered and shaded outside area for my outside pets here in the Southwest. Had to replace cooler pump at two months (June - July) of daily 14 hour use. If used a lot, or use is of any importance, I recommend keeping a new spare cooler pump on hand. Shopping around will show that replacement cooler pumps are readily available, ranging from $18 to $43. Cooler pump replacement is fairly easy with videos available online. I will have this cooler going 14 hours a day thru August, possibly September.
The overall size is convenient and will fit just about anywhere. For me, supplying water via the hose attachment is an absolute necessity, but the float valve only allows the water level to rise just high enough to completely cover the cooler pump, about 1/4 of the tanks capacity. The existing float is fixed, but adjustable floats are available from Hessaire.
I am disappointed in the plastic used for the housing as it seems to be brittle, so I am very careful with it. I never pick the cooler up by the provided handle if there is water in the cooler as I am not convinced the housing could take it.
For the money, I think it does a pretty good job....

spudvalley: I live at 7,500' elevation, so summers should be cool. This year is breaking records--we've had heat advisories for our area which NEVER happened before. Our dewpoints are around 35°, our humidity is about 15%, and the heat is in the low 90s. We don't have air conditioning and while nights cool off to the low 50s, it's not "good sleeping weather" for me. until the wee hours of the morning, not helpful for a good night's rest. This evap cooler works well to move air around efficiently and cools our living room to tolerable levels in the low 70s from the 80s we used to have. My only complaints are that it arrived without a user manual (which the seller sent to me via an email link) and the side panel has a bit of a bulge where it should be smooth.

amazon_customer: I got one as a shop cooler for a 2 car garage. This unit moves a lot of air. I had a smaller tower fan before and it wasn't working to cool much beyond the immediate area. I live in a low humidity state, and that makes swamp cooling a great alternative to compressor driven A/C. My garage does not have an external man door, so I have to position this by the garage door opening where it will draw in dry outside air. The ideal way would be to draw air in from one side of the garage and exhaust it out the opposite side, but I only have the garage door, so it's less than ideal.

Julia K OlsenJulia K Olsen: Finally decided to give it a try in my small (6x8 ft)greenhouse. Arizona summers are brutal and outdoor vegetables have never done well for me so I decided to keep the greenhouse going through as long as possible. Our temps have been grazing 100 but with our low humidity this cooler is perfect.

Normally when the outside temp reaches above 85 the greenhouse was unusable as even with the door open it would reach 110 and above, let alone when the outside temp are 105-110. Current indoor temps are running not higher than 95 daytime with about 50% humidity with door and window open. That's on low speed. I use about 10 gals water per day max. Perfect!

The pics are already a few weeks old but tomatoes, peppers, onions, garlic, cilantro, radishes are all doing great.  It really is a jungle in there.... I have never had such good growth here in the desert!

M&A: 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.
