The Symphony MMB10 portable evaporative cooler is small in size but big on performance.  Unlike traditional AC systems which utilize harmful, ozone-depleting coolants such as Freon, the MMB10 harnesses the natural cooling power of evaporation.  Using only tap water and electricity, this evaporative cooler covers up to 700 square feet and lowers temperatures by as much as 20 degrees at a fraction of the cost of a standard A/C.

The MMB10 provides low cost cooling where air conditioning isn't practical or feasible.  In fact, evaporative coolers can cost up to 75% less to operate than an air conditioning. 

Large Coverage Area
This air cooler covers areas up to 700 square feet, making it perfect for living rooms, dens, patios, garages, workshops and so much more. 

Blower Wheel Design
The Symphony MMB10 features an advanced blower wheel design for maximum air velocity and cooling. 

Ready to Use Out of the Box
No professional installation is required with the Symphony MMB10.  Simply fill it with water, plug it in and it's ready to go. 

Direct Hose Connection
A hose connection lets you maintain a continuous water supply without having to manually refill the unit.

Review Title: Good Product
Comments: We are very pleased with the evaporative cooler even though most of the comments I have read say that these are best in very dry climates. We use ours in the garage where the dogs seek relief from the hot summer and they love it. We put water and some very big ice cubes in it and the air that blows out is very high powered and cool and the dogs just sleep away the afternoon and one of them is a Great Pyrenees. Also it was delivered in less than a week as promised so that was even better since it was already hot. There was some assembly but it was easy and I did it all by myself with the dogs anxiously watching. Therefore we are very pleased and best of all we have not noticed any increase in humidity but definitely a drop in temperature.

Review Title: Great swamp cooler!
Comments: I have had my swamp cooler for 3 years now. I use it for home back yard patio. I have enjoyed my backyard more the last 3 years in the summer than all the 30 years I have lived in my house. My friends laughed at me first trying to cool the back yard but after having dinner on the patio one time they were convinced. It is a great product and very easy to use.

Comments: We were having a 4th of July party and was wondering what we could do to make every one comfortable, the ones in the pool would be okay but not the ones sitting on the patio, so we went and rented one and before the 4th I thought that I would look into buying one and then thought two litle ones would be better as I could face them in opposite directions and that worked out great, we use them every night sitting on the patio as it is so hot here in Texas. Every one at the party was very impressed with them and said how cool they were and not sitting around being hot.

Comments: I purchased the Mobile Master Cool evaporator cooler. This is obviously top of the line as soon as you see it and use it. No comparison to other units. This is one of the best working products I have ever purchased. Solid construction, ease of use and easy to move around. I am very impressed! Shopping was easier than waiting for it to arrive. Very informative and friendly website and ordering process. Shipped almost immediately and arrived right on time in professional packing.

Comments: I purchased this mobile master cooler and have used this appliance for a total of 5 days. Although San Francisco does not get extremely hot, we have experienced some very warm days. Also, because we live on the top floor of a 4 floor apartment building, it can get extremely warm. The cooler has been very beneficial for me and my family, and I would definitely recommend this appliance to others.
