Before you say it...yes I did do a search but didn't truly find an answer.

I have a whole house water filter and a reverse osmosis system (to my refrigerator) and I would think that it would be very close to distilled water. Would this be an alternative to distilled water?

From what I can tell, the difference between purified and distilled is very little.

However, since your purified water is coming from the fridge, it may not be as purified as you think. Totally purified water is not good for the body when consumed often, as it provides no new minerals to your system and can leech the minerals from your body. I'm going to assume that if there was any oversight on your purified water to your fridge then your filter may not filter out as many minerals as you would think.

A bit of a fallacy there, but we have gone over this before, and it seems fairly prevalent.


Properly maintained and functioning RO water from your fridge, assuming a clean "post" filter in your fridge doesn't contaminate the product water from your unit (assuming the unit is operating at an acceptable rejection rate and TDS levels are acceptable, the system has been sanitized and maintained properly) will be fine.


There is a lot of snake oil and misinformation out there, but having been ceritified (albeit long ago) with the Water Quality Association ( http://www.wqa.org ), I have seen this type of conversation many times.

why would you want to drink distilled water? but yes an ro system is the closest thing to distilled.

I am guessing since it is in the accessory forum, he is asking about it regarding his humi.
[Reply]

You are correct! Would RO water be a replacement for distilled water
[Reply]

Thanks for the info pete!

So, can he use his fridge water in his humi?
[Reply]

Distilled water runs about $0.99 a gallon. Once a year I splurge. :-)
[Reply]

You realize that once you open your distilled water, it starts to pick up impurities from the air and is no longer pure distilled water, right?
[Reply]

I'm assuming most of us don't keep our cigars in a clean room either. That same air touches your cigars when you open your humi.
[Reply]

no ro water should not be used as a replacement for distilled. there are many things an ro system does not remove from the water. even year old distilled in a closed container should have less impurities than distilled

$0.99? WOW! Big Balla!
[Reply]

well.... for this application...


Ugh... not gonna bother... again...
I won't respond to these anymore.

If it makes you feel better, use some distilled water, DI, shark piss, sauteed baby vomit, etc.

The whole distilled water debate is an interesting one. I use distilled water personally because that is tried and prove to work just fine. However my friend's wife has some pet toads and I was running to the store one day and she asked me to pick up some Spring Water for her toads, and explained that the guy at the pet store said that Spring Water was a higher purity than just typical distilled water.

What is correct? Who knows, it can probably be put up for debate. And with that, I actually have a water tester that tests for parts per million of impurities in water. Maybe I should do a test lol.
[Reply]

Actually I'm interested for what its worth.

I don't have RO system. Just a simple filtration system for the entire house. However I know my water gets some sulfur odor so I've never bothered using tap for that reason.

Eh-hehehehehehe.:-):-)

I believe we CAN know. Here is a great write-up on the matter:

And like Bob said, it's $1 for a gallon. :-)

Nope, and that's why he works at the pet store. If he would take some night classes he might
be able to work his way up to gopher at a tire shop. Distilled water SHOULD be water molecules
and that's it. Everything that isn't water should be left in the boiler or still. Spring water contains
whatever it came out of the ground with, unless it is filtered further, or even intensely filtered
further. But in terms of PURITY, distilled should win everytime. That's why it is used in labs and
stuff. It's water and ONLY water and will not contaminate tests with other crap. Even the best
filters and membranes SHOULD not be able to reach the purity of distilled water.

Denigration of pet store employees is not the direct intention of this reply. Intelligence level is
used for demonstration and hyperbole purposes only.

So it looks like I should go out and get some distilled water. Oh well, at least it was a good discussion.
[Reply]

Well here are my test results.. I did 3 samples from each source, and displayed the results accordingly...

TDS: Total Dissolved Solid

Tap Water:
From Faucet: 230, 230, 240

Spring Water:
Ice Mountain: 150, 160, 160

Reverse Osmosis
HyVee: 20, 20, 20

Distilled Water:
Great Value: 0, 1, 1
