Question:

Henry, Sounds similar to mine except I didn’t tap anything and I used an over the outside cap for the ends with no cement on one end. I just drilled the large pipe the size of the 1/2" pipe and cemented it with a sawed in half sleeve cemented on each side of the large pipe wall for reinforcement. Michael everything came from home depot. A dimmer should work for your heating element, Henry. But I would say it is overkill. I had in mind an aquarium heater. But, haven’ t had time to think about details. Sorry, I had to remove both your texts. My server won’t let an article on smaller than the original text. Gary

Gary I did not mean a $99.00 humidifier – I meant a CPAP for $99.00.

Gary I run a machine shop with some production capabilties. I also have some design experiance. There has been some talk in this group of a $99.00 CPAP. Want to have a go at building one? Thanks Mike My web site is www.machinerepair.com — Remove the two "nospam"s from the email address to reply

Response:

$99 or less!  Here’s one I am using that cost less than $25. Go to the plumbing section of local building supply company. Get a 4 (6) inch PVC clean out adapter.  This has a large screw-in plug and the receptacle it screws into.  You’ll also need a 4 (6) inch test cap and some pvc glue.  Glue the test cap into the non-threaded end of the clean out adapter. To connect your air hoses you’ll need 2, 1/2 inch PVC male pipe thread adapters and 2, 1/2 dia. x 2 inch long pieces of PVC or CPVC pipe.  The threaded clean out plug has a large square lug in the center; there’s just barely enough room to drill and tap one hole between the lug and the outer diameter without getting into the threads.  Drill and tap the other hole in the center of the lug. Once the holes are drilled, glue the male adapters to the short pieces of 1/2 inch pipe.  After the glue has dried, wrap the threads with teflon pipe tape and screw them into the clean out plug.  The PVC cement packs quite an odor, so allow a couple of days before using.  You will want to clean this thoroughly too. Now with the test cap on the bottom, the clean out adapter makes a cylindrical container.  Put about 1.25 cups of water in the bottom then, using more teflon pipe tape, hand tighten the plug into the adapter with the 1/2 pipes on the outside.  Connect the air hose from the CPAP to the outermost 1/2 pipe, and connect the air hose to your face mask to the 1/2 pipe in the center. I have also tried heating this with a heating pad with good results. But, beware, this is not the intended use of heating pads, or clean-outs.  You may set your house on fire, get electricuted, culture the growth of some horrible bateria or fungus, or have some other unforseen negative outcomes. This entire apparatus should be used at your own risk. I will not accept any liability for any property damages, bodily harm, or death that may result in its use.  I’m just a grad student that can’t afford $500 for a heated humidifier.  Suing me will be a waste of your money, I have none!  Part of the $500 is to pay for product liability, testing and certification, with this there is none!  This is the internet not a medical supply house! With that said: My next generation heated humidifier uses a $20 coffee maker with a natural rubber stopper in the opening.  I’m having a hard time finding an off the shelf stopper (#16 stopper).  I figure by placing squares of aluminum foil between the bottom of the coffee pot and the heating element I should be able to cut down on the evaporation rate.  From what I can tell a 25 watt heater would be more than sufficient, but most coffee pots are much higher than that.   Even thought this is the internet and some people love to flame at the drop of a keystroke, any help, comments, suggestions, criticisms, or ideas would be appreciated. – Hide quoted text — Show quoted text -Michael Morgan wrote: > In article <35374fea.3541…@news2.new-york.net>, > chief…@unix.nospam.asb.com (Jim Strand) wrote: > > On Thu, 16 Apr 1998 22:38:34 -0400, Gary Collins > > <coll…@preferred.com> wrote: > > >I built my own out of PVC pipe and I have used it three nights now (unheated) > > >with good success.

Gary, Place me on your list of those most interested in a home built heated system.  I to cannot accept the wild numbers the manufacturers come up with.   Just one simple request.  Kindly select your components from a major supplier like Home Depot, Lowe’s or equivilent.  That way we can be assured of finding the parts in our communities as well. *************************************** delete "nospam" for e-mail reply ***************************************

Michael, First of all I had trouble following the thread on this so I hope I am addressing it to the right person. I had the same problem you did with an unheated humidifier. In fact my respitory therapist said "a humidifier is just a luxuary, most patients don’t have one". I can’t vouch for anyone else but I have asthma and have had an especially bad winter and spring. I heated my humidifier with a heating pad for two years. It may have been the cause of it’s early demise but, it was worth every watt of heat. It sounds like you and I were doing exactly the same thing. It worked well for until my humidifier but the dust (or should I say wet the dust down), last week. I tried some really good industrial cement but after waking up with a desert in my nose, throat and lungs. Two night I said enough. I built my own out of PVC pipe and I have used it three nights now (unheated) with good success. I find that as the weather warms up I really don’t need heat because the relative humidity comes up to. I haven’t devised a heating system yet. I have some Ideas though. Iam still working on the development. It cost about $25 to build and unheated really works better than the Respironics unheated one. I am an electronics engineer and I want to try to design my own heating system and regulation for this thing. It really gripes me that the medical companies can charge $300 for a plastic box with two pieces of pipe attached. I realize that my insurance would pick up 80% of this but that still means $60 from my pocket for a plastic box that should cost $30 alltogether. I’ve seen more Lexan plastic in a popcorn popper. If I can help anyone let me know.

Eric, My wife has always liked those cold mist humidifiers when she has a cold and I hav always liked the good old steam vaporizer. The air doesn’t come out hot or really even warm, just not cold and with much more moisture. With the heat I use about twice as much water as I did before and don’t wake up with a parched throat all night long. I also now wear a chin strap and still prefer the heated humidifier.

I’ve been using the same setup for over 8 months with no problems. Except of course I’m not so sure it really helps.  That post earlier by Bill of BillsCPAP makes me wonder even more. >Remove the two "nospam"s from the email address to reply

My insurance will not pay for a heated unit and the Oasis unit I got is way to cold and not much help at all. So I put a heating pad underneath the Oasis and now I have a heated unit that works really well. I also put a towel under the heating pad and a towel on top of the Oasis to keep the heat where I want it. It really works. Mike — Remove the two "nospam"s from the email address to reply
