DIY Adjustable Bed Fan/Bedjet substitute under $150 

This is golden good Sir! Thank you. Looks great too! Im in the process of building something similar, not as nice looking as yours, but hopefully as efficient. My sleep has suffered for as long as i can remember and Im ready to change that as I too am a hot sleeper. We have the temp at 67 degrees at night and my body becomes a furnace under the covers. I'm either too hot or too cold and nothing in between so I toss and turn all night. I bought a duct fan on amazon at 195 CFM with a plastic duct to run under the covers and have an extension cord that has a sliding adjustable setting. Im praying it works. I can no longer afford to have poor quality sleep as it affects my day to day.

Nice job! I was just gathering ideas on building vs. buying the bFan. Thanks for the info.

This is really slick, may try to build one. Thanks for posting!

I'm building my own setup, just ordering parts now. My wife likes to sleep under a blanket year-round so it'll just be for her side of the bed; I'm happy to sleep with just a sheet in the summer. Bedjet sells their flat hose accessory for $50 as a standalone without having to purchase an entire system (I'm also buying their overpriced $99 twin sheet that's designed to receive the nozzle from their hoses). This is much less work and no sharp metal near the bed for probably the same (or less) cost as all that 30g sheet metal. Between the flat hose connection point and a basic 120V Amazon 195-CFM 4" fan I plan to cut two 4" round holes in an small hard-shell cooler so it can be filled with varying amounts of refreezable ice packs. This allows for additional cooling at a level we can experiment with and vary depending on the house temperature . . . happy wife happy life. Although my setup will be different I appreciate your ingenuity and sharing your way of coming up with a solution.

I gonna totally make one of these after my Bed Jet pukes. Bed Jets DO NOT last long before the motor burns up. Can’t repair, I tried! I’m on my 3rd one in six yrs. They make it impossible to find the mega cheap made in china motor to fix. And Bed Jets warranty sucks! Thanks!

I learned from another video that duvet covers can be used instead of the Cloud Sheet since it has button closures and a pocket to put the BedJet head into (much cheaper than buying the Cloud Sheet itself). I like the idea of that since the air flow would be more evenly distributed instead of just on my feet/legs... but that leads me into a question - Do you know of a flatter head that I can use to replicate the head on the BedJet? I imagine I need that "flat duck billed" shape that they use in order to fit it inside the pockets of the duvet cover so I can seal it up, either that or I need to reduce the 4" opening down and then fit something more wide and thin on.

Andy - thanks for sharing the video! How many cfms does the 6 inch fan put out ? Pressure high enough to overcome the weight of the comforter and get good distribution of air? Thanks again.

How has it held up with time? Thinking about building something like this for my wife.

Did you open the imperial polypropylene exhaust vent?

I think I'd put the fan somewhere else if it fails your bed will be the fuel for the fan fire which do happen

Can you get a stronger fan? My wife has to have strong air flow

Couldn't you just buy Bed Jet's own hose for $50 and pair it with an Inline 4" in fan..?
