Does a dehumidifier lower a room's oxygen level?

Unless you are using a coal powered dehumidifier that burns oxygen and produces CO

Uhmm, it may lower the amount of oxygen per mole of air because there is more 'free space' in the air for the oxygen to arrange themselves in, but this should be relatively minimal. No idea what heating it would do??

That sounds like a load of bs to me.

You're breathing in your house. Are you worried about that depleting oxygen?

Huh? You only need to worry about oxygen levels when you're running your "singing arc" plasma speakers in a confined area.

I use an air purifier (Water suction based) and an air deionizer (HEPA Filter based)...works better than dehumidifier which dries the air in the room..which is harmful unless u live in a very humid climate or issues of molds or fungus (which i had before i got deionizer)



it shouldnt lower oxygen level...because their is no combustion (unless your works on non-electrical principle) it only lowers the humidity in the air based by condensation.


which dehumidifier are u using? and what is the specific reason u r using it?

i can help as i did lot of research before buying deionizer... had lot of issues in the room.

in any case..u shud have ventilation in your room for fresher oxygen.



oh and

I wouldn't worry about it at all. You don't even really need to worry about oxygen levels until you have very thin air at very high elevation or you deplete the O2 levels of the air by 25% or more, which is damn difficult to do. No matter what you try.

We have been using a dehumidifier (small one) in the bedroom for a couple of months now. We leave it one the whole night. The manual also states to turn on the heating but only because the increase of room temperature allows for a higher rate of extraction. We never leave the heating on at night.

I see you're in Texas....what fun weather (I've got nearly a foot of snow outside right now )

what I do remember of living in more humid climates than Denver, run the A/C, cool the air down, if you've still got this massive humidity, are you sure its environmental, and not water pipes or similar? (if the carpet feels "wet", that isn't generally normal)

if its just massive humidity (I don't doubt it), get one of those dehumidifiers, and crank the thing up, I've never had an issue with "removing oxygen" from the room (but like walkingman says, heating the room will help it pull moisture out (it has a freezing plate and tries to condense water out of the air, warmer air will "react" more properly, than if its "cold" is only a few degrees away from the room's ambient))

@nocturnal:
I think you're talking about something a bit different, but I'm not sure, you're talking about air cleaning, not humidity control (here's where I'll admit: I don't know how humid your environment is, but I will tell you, Texas is not a "fun" place to be in the summer with no A/C and no dehumidifiers), although I'm not really sure what your two devices do (or what your motivation for buying them was, you're talking about mold/fungus removal, which is a bit different than what the op wants (I'm assuming, based on when I lived in the southern US, its more about getting things "comfortable")

one thing I will point out the OP:
dehumidifiers are good as "additions" if your location isn't "Great" with A/C (for example our church had window units all around, and we'd run dehumidifiers in the main hall to help out, but our home was newly built and had a trio of big AC units (idk? 100k BTU? 200k BTU? something ridiculous, it'd run the house at 60* F on a 95* F day, with a 20-40% difference in humidity)), but if you can go with a "badass A/C system named Butch", thats usually a bit "easier" (you aren't emptying the dehumidifier out, and its "global", because it influences the entire building/house/apartment/whatever, vs 1-2 rooms)

just my experience, take what helps you, ignore the rest

PS:
nocturnal, can you give me a link to some information about your air filter (the water based thing you were talking about), I'm sort of looking for something "bigger" than what I have atm

the water based thing is a very simple device...its made by a German company called 'H20' also ..and by many china generic brands.






it creates a vortex like thing in the water which absorbs larger dust particles in the air, it keeps the air fresh..prevents the stale odour.

and the solution with it is anti-bacterial/fungal ..also spreads a natural aroma.

the Deionizer is a more complex and expensive device.



Btw..i didnt know the Texas humidity issue...but in any case.. a non-combustion device shouldnt cause oxygen depletion in the room....but just to be safe ..always have ventilation in the room.

You use a humidifier with heat and a de-humidifier with AC. Humidity holds heat in the air longer. AC pulls that moisture out to drop the heat. I know of nothing using water that acts like a de-humidifier.

Using a de-humidifier will also put mold into the air if you don't keep the bucket, filter and filter housing and cooling coils clean.

There is nothing I know of that reduces O2 levels. Your only drawing moist air across a cooling coil. Moisture condenses on the coils, drains into the bucket. Hospitals use both refrigerated and chemical dryers on their medical air systems and neither have an affect on O2. I know this because this is my business.

Noc,

That device looks like what Rainbow says their vacuum cleaners will do too. They use it to "wash the air clean" as another reason to spend $1500 on their vacuums.

can't you get mold with a nasty humidifier as well? (just curious)

whats wrong with water sequestration? its usually a helluva lot cleaner than dealing with a "dusty filter box" and shaking things back into the air

noc,
that was totally smaller than I expected
thanks for the info though

Yes, anything drawing house air through it will entrain mold. Depending on the conditions, there are molds, spores and bacteria that could infest your unit and cause a real problem in your home. Weekly cleaning is recommended. Many people have these units built into their HVAC systems. They ignore cleaning and then get sick.

Nothing wrong with sequestration. I was pointing out that Rainbow vacuums use this as a selling point for justifying their cost. Quite expensive compared to what Noc showed us. Again, keep clean.

aren't Rainbow vacs those canister things that were trendy a few years ago?
