You’re not the first to think of the question, “can I put colloidal silver in my humidifier?”. In fact, I’ve actually tried it! So here’s what to know if you’re thinking about putting colloidal silver in your humidifier, are ready to try putting colloidal silver in your humidifier, or want to improve your plan to put colloidal silver in your humidifier.
Can I Put Colloidal Silver in My Humidifier?
The Short Answer: Yes! The answer to “can I put colloidal silver in my humidifier?” is yes.
But we’ll get into what you should consider before adding colloidal silver to your humidifier in a second, so don’t run and dump it in yet!
In general, you’re not going to hurt yourself and *probably* won’t hurt your humidifier if you try adding a little colloidal silver. As part of the longer answer, though—there may be a better way to achieve your goal than adding colloidal silver to your humidifier.

What Happens When I Put Colloidal Silver in My Humidifier?
Now that we know that you can put colloidal silver in your humidifier let’s look at what happens next.
When I added colloidal silver to my humidifier, a good portion ended up coating the inside. I can’t say if any actually ended up elsewhere (like in the humidity it put out), but I was wiping silver particles off the inside of the reservoir for a long time.
Meanwhile, the humidifier stopped having any things (like pink slime) grow in it. So while I don’t think it did much for health support, it did seem to help keep the humidifier cleaner. It didn’t break the motor, but I didn’t add a lot or do it over a long period. My humidifier has been near-constantly running for 8 years this October, with no sign of trouble.
Why Should I Put Colloidal Silver in My Humidifier
So, to say it’s worth it if I can put colloidal silver in my humidifier—that depends. What’s your goal? There are two main reasons I can think of to put colloidal silver in your humidifier—to make your immune support airborne (especially during cold and flu season) and/or to keep the gross stuff that ends up growing in humidifiers at bay.
To Keep My Humidifier Clean
Check the manual if your only goal is to keep your humidifier clean. My humidifier recommended a weekly cleaning with vinegar, which I do passively after shaking it around the inside of the reservoir and letting everything sit in pure vinegar. Then I dump, refill, and carry on—but it doesn’t 100% stop pink slime and other build-ups between cleanings, and a tiny amount of colloidal silver may help.
Whenever people use colloidal silver for its germ-fighting properties to clean, we recommend Hot Tub Silver. It’s a lower-grade colloidal silver that’s perfect for cleaning and, as it’s named, is used by others to keep hot tubs clean. It would probably make a good fit for humidifiers, too.
Note: there’s no reason colloidal silver could or would stop calcium deposits from forming, so if that’s the problem you’re having, try a water softener instead.
To Put Colloidal Silver in The Air
If you’re trying to smartly bulk up your immune support by getting colloidal silver into the air you breathe, it’s not a bad idea! But there’s a better way!
While you can put colloidal silver in your humidifier, if you’re trying to get that immune support directly into your respiratory system, eyes, sinuses, throat, lungs, and more, you’ll have much better success using a nebulizer.
Nebulizers don’t require prescriptions—people who have prescriptions are taking medicine (usually steroids) through a nebulizer, and that’s what the prescription is for. But there are other things you can put in nebulizers that don’t require prescriptions, like colloidal silver.
If your goal is breathing in immune-supporting colloidal silver, use a nebulizer instead.
What You Should Know If You Put Colloidal Silver In Your Humidifier
This article is in no way intended to assure you that colloidal silver in your humidifier won’t clog, destroy the motor, or cause other problems. Do so at your own risk, and check through the manual. Every humidifier is different.
Moreso, this was meant to look at how you can use colloidal silver (rather than how you can modify your humidifier). From the perspective of colloidal silver, yes, you can put colloidal silver in your humidifier—but do so at your own (/the humidifiers) risk.
