Keepin' Cool Misting System Radically Cools Your Outdoor Spaces

Last year we shared the magic of flash evaporation and its instant cooling powers with you. If you’re looking for an inexpensive way to take advantage of it, this cheap misting system will keep you cool all summer long.

What is flash evaporation cooling and how does it work? A recap from ourprior article:

How do misting systems work? Water is forced through small diameter pipes or hoses to tiny nozzles which release the water in such a fine mist that it appears almost fog like. The droplets are so small most of them will evaporate before even touching your skin and effectively lower the temperature around you 15-20 degrees via the magic of flash evaporation. The amount of water required to cool a large residential deck is only a few gallons an hour since the water is being released through such tiny holes. To put that in perspective you could cool an entire dinner party for as much water as one guest will use flushing a toilet and washing their hands.

The Keepin’ Cool system hooks up to a regular garden hose and attaches via included clips to your patio umbrella or other elevated surfaces in your outdoor spaces—rain gutters, edge of the second story patio above your deck, etc.—for flexible anywhere-you-need-it cooling. The only caveat we can offer when considering such systems is that they work most effectively in drier climates. We’ve experienced them in both humid and arid locations before and felt cooler in both instances but flash evaporation works most efficiently when humidity is low.

The Keepin’ Cool system is $19.99 and includes a 10 foot supply line, 10 feet of misting hose, and assorted clips and hardware for hanging it. Don’t feel like paying for it? The same idea is ripe for a DIY implementation.
