"distilled" water for wife's CPAP machine

Post by dm200 » Mon Jun 18, 2018 3:31 pm

My wife uses a CPAP machine at night and the one she uses has a container for water. She buys "distilled" water.

Before I suggest this to her - I wonder if the condensed water from a dehumidifier might be satisfactory as a "free" alternative?

No because the collection container from the dehumidifier will be contaminated.

Only if it’s a steam dehumidifier, not ultrasonic. But it sounds like quite the contraption to save a buck a month or whatever a gallon of distilled water costs. They also make home distilling machines, but the payback for the machine would take 10+ years so I’d say it’s only a good idea if you can’t buy distilled water in your area or something.

While my instinctual reaction to your question is "no", I honestly am just expressing an opinion without any support.

That said, is finding the distilled water a concern? I buy a gallon of it about once every 2-3 months for $0.78 while I'm out for groceries anyways (my CPAP is the only item I use it for). I get your wife's usage could easily be significantly higher than mine, but are we really talking a difference that isn't in the "noise" range?

Oh I read it as condensed from a humidifier, oops. I wouldn’t use water from a dehumidifier, it’s nasty, all kinds of dirt and bacteria from the air.

Mine regularly grows mold if not careful. Seems like the opposite of a pure water. more likely to cause new respiratory issues...

You're talking about a potential cost of savings of maybe, 6 ounces/day at a cost of, say, $1.29/gallon = $0.06/day or $22/year.

Since there is no expectation that people are going to drink, let alone breathe the water condensed in a dehumidifier, there's no reason to expect there's been any attention given to the possible health issues of the same.

Mold, bacteria, and Legionnaire's disease grow in damp places--Legionnaire's specifically in water condensed in air-conditioning system. I would not think of taking the risk of putting water into a system I was going to be breathing out of if I thought there was any possibility of contamination.

By all means go price-shopping on the distilled water.

I was thinking more just of biofilm in the collection container, but Legionella infections infections in particular have been caused by medical equipment, including CPAP machines. I agree that you don't want to increase that specific risk by using water taken from another device that can also harbor Legionella.

I've been using a CPAP for about 7 years and my annual cost for distilled water is about $11.00 a year - 12 gallons. I also clean the mask and the tank every morning. The hose about once every two weeks. Also change the filters monthly. This is not a device that you would want to skimp on for supplies. Breathing air that's been been humidified with warm water is something that becomes very risky if the water or container becomes contaminated. You're better off saving money on something that isn't essential to your health.

No. The reservoir chamber on the dehumidifier is not sterile, and she'll be breathing in all sorts of unhealthy crud.

I get distilled water for my CPAP by the gallon jug at the local grocery. Be careful to make sure the word "distilled" is on the label. Some say "purified", which is not the same thing.

I was a Registered Polysomnographic Technologist (sleep tech), albeit many years ago. Your wife inhales water vapor from her CPAP humidifier deep into her lungs. Using anything other than distilled water would be taking a big chance. Also, it's important to keep her CPAP equipment (mask, hose, humidifier) scrupulously clean and free of mold and any other contaminants. Trying to save a few bucks on cheaper water would be foolish.

While you’re at it, buy her a cleaner (I think the name is SoClean2). Runs a 10 minute ozone cleaning of the hose, mask, and reservoir every day.

Be grateful that the distilled water doesn't come in little single-use cartridges with one night's supply of distilled water, at $39.95 for a box of 24--with RFID chips in them, of course, so that the machine will only run with genuine manufacturer-branded cartridges.

As stated, the water from the dehumidifier is exactly the opposite of sanitary. I have been using a CPAP with humidifier for 10 years. I have always used distilled water, except once when I ran out. I used our very hard tap water, as, as I assumed, it left a mineral scale behind that was difficult to clean. If you have an ALDI near you, they have the lowest price I've found. I think it's $.89/gallon.

Wow, the price of the little bottles of distilled water are EACH several times the price of a gallon! What a ripoff! You could just buy a new gallon bottle each week for the less than the price of those small 11-12 oz bottles—wow!

Agree that you want to keep it as clean as possible and certainly not use old distilled water. There is no point in increasing the risk of pneumonia.

If you must, you could probably collect the leftover water to use in steam cleaners, humidifiers, steam irons, etc., where the vapor doesn't go directly into your lungs.

It is true that it is mostly + or - $1.00, although I found a quick stop where it cost about 3.00. Will try to avoid that if possible. My usual grocery has been out of it twice in a couple months--not sure what is going on there.

I use water from a reverse osmosis system for the humidifier tank in my CPAP machine. No issues so far. Still have to clean the cartridge a couple times a week, though.

1. No for good reasons that are already listed.

2. Ask your pulmonologist, or your primary care doc if you don't trust those answers.

Not in this instance. Taking care of the pence is likely to cause health issues that require pounds to fix.

I stopped using humidifier, and I discovered that it took two nights to adjust without it. Sure, in the beginning, my throat was a little bit dry.

Less maintenance for me, and fewer things to buy. @UpperNWGuy, ask your wife if she is willing to try not using humidifier, if that works, that is great.

Whoa.... I think you might be confused. I am not the OP, and I don't have a wife. I do, however, use a CPAP, and I always use it with a humidifier. Without the humidifier, the inside of my nose gets irritated.

I just started using a CPAP 2 months ago. When I picked up the machine. I asked the therapist if it was necessary to use the humidifier. He said no. I have not been putting any water in it. I figure it is the same air I would be breathing if I did not use the machine, so why add moisture?

I agree that the solution he proposed is not a wise one--you can see above that I responded that way immediately.

However, I'm not sure why people are giving him flack about thinking about a less expensive solution than buying distilled water even if it is only, say, $12 a year. After all, water is often free or nearly so. He asked a legitimate question and got answers. Apparently some people think that the question isn't legitimate.

I don't like spending money if it's not necessary or beneficial to do so, either, and think about even small expenditures. So I'll say it again for extra emphasis:
Take care of the pence and the pounds will take care of themselves.

Re: "distilled" water for wife's CPAP machine

I think the reason for skepticism of the OPs question is that it’s an insignificant amount compared to the risk of not using distilled water. Sure, there are many ways to economize on small things that add up to decent amounts. Health is not one of them. Skip the Starbucks, bring a homemade lunch to work, get basic TV, buy a Kia rather than a Lexus. But try to save $1 a month on something that affects your well being? Better to use your CPAP without the humidifier. Did the once by accident - my mouth was stuck shut when I woke up 🤐.

My older cpap uses a separate stand-alone humidifier in which I use tap water that I change on a daily basis.

But the newer cpap models with integrated humidifier should only use distilled water (to prevent damage to the CPAP unit).

My wife uses a CPAP machine at night and the one she uses has a container for water. She buys "distilled" water.

Before I suggest this to her - I wonder if the condensed water from a dehumidifier might be satisfactory as a "free" alternative?
OP, thanks for this post. I'm going to show it to my wife because she thinks I'm cheap. :D
