EcoBreeze 2 The Smart Window Fan

  • SMART COOLING – Set the desired temperature. Auto mode maximizes the use of cool outside air and brings it in whenever it is available and needed. All summer long
  • CLEANS THE INCOMING AIR – Filters out pollen, mold and dust to keep indoor air fresh and clean
  • WORKS WHEN AC IS ON – No need to turn off the AC and open windows –.The smart controls insure that the outdoor air is always cooler than the indoor air before it turns on.
  • VARIABLE SPEED – Fan speed automatically adjusts to provide just the right amount of cooling
  • SEALS UP – insulated side panels, weather strip and damper doors make sure the hot air stays outside. Designed to keep rain outside eliminating moisture issues.
  • EASY TO INSTALL – Installs in minutes
  • STREAMS AIR – Adjustable louvers direct the air where it is needed up to 20’ from the window
  • LOCKS OUT THE HUMIDITY – When AC is running optional lock out prevents cooling with high humidity air
  • ENERGY EFFICIENT – Uses about the same power as an LED light bulb: 70% less than traditional window fans
  • GREAT FOR THE ENVIRONMENT – Take advantage of cool seasonal and night time temperatures and save energy on summer air conditioning


EcoBreeze 2 turns your regular window into a smart, cooling window. The EcoBreeze 2 fan will automatically bring air inside when it’s cooler and less humid outside. How does it work? Effortlessly!



Set your outdoor air cooling temperature below your AC set point and the controls automatically cool when the outdoor temperature drops and cooling is needed.  When using both outdoor air and AC choose to lock out humid air.  Take advantage of cool air even after you leave for work or anytime you are away from home.


EcoBreeze 2 has a convenient pull out filter. It comes standard with a MERV 8 filter that removes pollen, dust mites and mold spore.

The Optional MERV 13 eliminates viruses, bacteria, smog and smoke.

More on Filters


Your comfort zone is the range of temperature from where you are uncomfortably hot to where you need to reach for a sweater.

Set the AC temperature below the uncomfortable hot zone. Set the smart fan temperature near you sweater zone. ]When it is cooler outside the Smart Fan automatically brings in cool air to lower the room temperature. When the outdoor air is too hot or humid the AC will cool the room down to its temperature setting. Increase the difference between set points to increase the savings.


The fan is programmed to run on the minimum speed to meet the cooling need based on the temperature set point and outdoor temperature. In a typical night it starts on low speed, gradually increases the speed as the temperature drops and then gradually decreases the speed as it nears the set point. This maximizes energy savings and maximizes running on low quiet speeds.


Weather strips and insulated side panels seal unit in window. Intake and exhaust damper doors keep hot outdoor air outside. Installation insulation exceeds Energy Star requirement Room Air Conditioners Specification Version 4.0.


Continuously compares indoor and outdoor humidity to avoid cooling with humid outdoor air when the AC is on. Turn off when the AC is not being used. The air intake is designed so the unit can cool even during rainy weather


Energy efficient dc motor uses 7 watts of power on low and averages under 20 watts in the auto cooling mode, 70% less energy than traditional window fans.

Reducing air conditioning use adds to the savings. EcoBreeze 2 uses 98% less energy than an AC so the savings add up over the life of the unit. More on Energy Efficiency


While our planet is warming, using and producing air conditioning equipment exacerbates climate change. The HFC refrigerants we use have a global warming impact of 1000 to 3000 times more than carbon dioxide.

The energy used or run ac comes from power plants including coal fire plants that also contribute to global warming. One of the less know issues is that the heat produced to cool our homes is exhausted into the outside air which adds to the temperature rise in our cities. While AC is needed to for hot humid days, substituting natural sustainable cooling whenever it is available is an action we can all take to help reduce global warming.
