Powerful DIY Multi Room Super Cooler. Easy To Make, Up To 30 Degree Drop In Temperature, And It’s Saves Big Dollars On Your AC Bill


There are quite a few DIY/homemade air conditioners, and air coolers all over the Internet. We’ve got directions for some of them on this site. Up until now those AC’s were more for small spaces, rooms, or cars. You might call them personal coolers.

What we have here is a Super Cooler that is capable of cooling larger rooms, or even multiple rooms. With this super cooler you can experience up to a 30 degree drop in temperature. It is portable enough to move into different rooms if need be.

Better yet make several for different rooms. They are inexpensive to make, and you’ll save a lot of money on your AC bill. You are going to love how well this works. The video below will show you how to build this super cooler.

Designed to be used with a standard 20″ box fan. Run-time: 6-10 hours per fill-up (holds 3 gallons). All supplies are easily found at the home stores.

Notes on construction, and what you’ll need to make this Super Cooler:

wood used; one 10 foot 2×3 (99.75″ in total). twelve 2 1/2″ wood screws. one heavy duty “

CoolPad Ice” all season cooler pad. one roll (2ft by 5ft) of metal screen, called “hardware cloth”. 5/8″ vinyl tubing (1/2″ internal diameter).

200GPH fountain pump (from harbor freight). one 2′ long piece of pvc pipe (1/2″ diameter). assorted pvc connectors. 1/8″ drill bit for water holes. 7/8″ spade bit to cut hole at top of wooden braces.

one 24″ long window box (7″ high) from walmart.

Note…The Super Cooler works best in semi-dry and dry climates *the drier the climate the better it performs – also, for best results, use a strong/powerful fan. Tip: to dry out the cooler pad do not remove it. just shut off water pump and let fan run.

it should be completely dry in 15 to 20 mins. only remove cooler pad when replacing it (once or twice a year – if you use heavy duty one). you may need to use some pvc pipe cement if there are any leaks (on non-threaded connections). it’s only about $4 a bottle. (i didn’t need to use it.)

You may need to use teflon tape on any connector that is threaded and leaking. cooler is totally self-contained and area around cooler stays completely dry. (ran it all day for 3 days and observed no water at all outside of the air cooler).

Notes from the video:

Homemade Evaporative Cooler. This DIY Window/Planter Box Air Cooler is simple to make, very sturdy and powerful. cools air up to 30F. full easy instructions. made using: plastic planter box, towel, one 2×3 (96″) board, one 3/4″ (48″) wooden dowel, 12 2.5″ wood screws, a fan and water. holds 2+ gallons. just add water, rotate towel to saturate and turn on fan. works best in dry climates (the drier the better – as it adds humidity to the air).

Cost: about $10.00 not including fan ($1.98 for board, $2.98 for dowel, $1.99 for towel, $1 for flower box and $2.29 for the wood screws). tips: use the thickest most absorbent towel you can find. rotate towel frequently (every 30 to 90 mins), try using cold water or adding ice for extra cooling. dry out towel after a days use. wooden dowel just slips out, so it’s easy to remove (or replace) the towel. the wooden stand can be used with any standard plastic planter box (18″ 24″ 36″ etc… just alter the length of the wooden dowel). planter box in video is 24″.

Towel used was 49″ long by 29″ wide originally. (i trimmed the width to 18.5″ and kept the length the same). just sew the towel end to end). cut the 96″ (8 foot) 2×3 into 8 pieces: Two 3.5″ lengths, Two 4.5″ lengths, Two 15″ lengths and Two 25″ lengths. cut the 48″ (4 foot) 3/4″ wooden dowel into 2 pieces. (approx. 19.5″ each – but measure that carefully to fit your stand and flower box ).

I used a 3/4″ spade bit to cut the holes for the wooden dowels. drill about halfway through. the 12 wood screws are 2.5″ long. I used a standard 20″ box fan but all sorts of fans can be used. finally, this could easily be run “off-grid” using a DC fan (or fans) directly connected to a solar panel (or an AC fan connected to a small solar panel/battery system). Note that the main body of the video is only 7 mins long. last 4 mins just show the second (a duplicate) wooden brace being built.
