This Video Shows How To Convert a Standard Household Box-Fan into an Evap Cooling Box-Fan! very easy to do! unit drops air temps 15 to 25 degrees below the ambient air temp. a fan speed of medium or high works the best. unit uses 0.5 to 1 gallon of water per hour (depending on ambient air temp, humidity and fan speed). many types of containers can be used to hold the fan including: planter boxes, ice chests and plastic totes. all items (except the pump) can be found at the home stores (home depot etc). the pump can be found at harbor freight tools or amazon. the home stores may have it too, but i didn't see it there. total cost: about $45 (not including fan). parts list is shown at the end of the video. tip: don't skip the "styro-foam block" step of the project. the blocks create the needed air-space between the evap pad and the back of the fan. (you can usually get styro-foam for free just by looking in any old boxes you may have). works great inside or outside. if using it inside place it near a door or a window and use the cross ventilation technique to keep humidity levels low.

    You heatedd us in the winter, now you're cooling us in the summer!

    Got the itch to make a "new" swamp cooler after using the 5-gallon bucket one for a couple years. It's been working great. Came back to check your channel to see if you've got any new designs - was pleasantly surprised to see you uploaded under an hour ago!

    I made one similar to this a few years ago with a wooden frame and I used hardware cloth to hold the Aspen pad in place. I got a little fountain pump and I ran tubing up over the top of the pad and just poked holes in it with a pushpin. On mine the fan was completely separate from the cooling unit. It worked quite well. Always enjoy your videos.

    Thank you for another great video and sharing every thing to have and do to make it! Awesome!

    Great and simple. As evaporative cooling is completely dependent on relative humidity a search for "effectiveness of evaporative cooling at different temperature and humidity" (look for images to quickly find charts) or similar will advise the effect one can expect to achieve. A regular or dissicant (calcium chloride) dehumidifier in a closed off room may make more sense than cross ventilation in areas where the outside humidity is too high for effective evaporation. I would post links but I believe youtube would block them in comments. Thanks for simplicity, just don't want anyone to think they aren't getting good results without knowing why. In Arizona an open ventilation will usually be fine. In Florida, not so much.👍

    You always have such great ideas. Going to share your channel with a couple of friends who could use your ideas.

    Nice video , thanks for sharing , God bless !
  • @dolan660
    hey man love the videos. i was wandering if you could do a dehumidifier and evap cooler conversion. thank you
  • @ryanhenry7727
    I appreciate this content its inspired me alot. I hope at one point you revisit dehumidification. Its a big problem where I live and I want to do a DIY project like yourself to figure something out. Have a wonderful day and thank you again.

    Very nice. We were just talking about excessive heat up here in the mountains of western NM. 82 in the house but low, low humidity makes it almost tolerable
  • @NotWhatYouThink
    Very nice and compact design. I thought evap coolers need to sit outside, with a flexible duct bringing the cool air in. Would this work inside an enclosed space (say a tent?)
