Moreover, this comes in a pack of 2 or 5, depending on your needs. It’s also compatible with many ultrasonic and evaporative humidifier models. Aside from reducing the mineral content of hard water, these tablets also help neutralize malodors. It will also reduce the risk of bacterial formation in your unit.

How to choose water softeners

There are a few options in the market when it comes to water softener tablets for humidifier. To help you choose, here are a few considerations to keep in mind:

✔️Choose the type

Water softeners for humidifiers come in tablet, capsule, and cartridge forms. All of these work wonders in absorbing the mineral content of the water.

Tablets can help clean the humidifier, but it’s not the most efficient when it comes to demineralization. Nevertheless, it’s a convenient and cheap choice, especially if your water isn’t that hard.

On the other hand, humidifier capsules and cartridges are the most common options. The tablets and demineralization components are encased inside a plastic housing. You simply pop it into your humidifier water tank, and it will do its job.

✔️Check the components

Most demineralization tablets and cartridges in the market are made of potassium salts. It’s either potassium chloride or sodium chloride.

Once the tablets are added to the water, the salts will release ions. It will neutralize calcium and magnesium ions that are the cause of hard water.

Overall, these components are safe to use unless you have an underlying health issue. When in doubt, it’s always best to consult your physician.

✔️Mind the proportions

For efficacy, you should use enough water softener tablets that are proportional to your humidifier. In general, you’ll need eight grains of sodium for each gallon of humidifier water.

It’s not really dangerous to use more than this, but it will be just a waste of money. The good thing is that most manufacturers advise on the number of water softener tablets you need to use.

✔️Consider the price

Lastly, you should check the price of the water softener you’re going to use. Most of these tablets are available for a low price.

Still, you should avoid very cheap ones, especially those with packaging that lack information about the product. While you may need to shell out a few more bucks, it’s best than using substandard water softeners. The worst thing about these cheap softeners is they might be laced with harmful chemicals.


Frequently Asked Questions

Q: How do you treat hard water in a humidifier?

A: Hard water in humidifiers can be used by using demineralization cartridges. This will absorb the mineral content of the water, so it doesn’t get released into the air. If you don’t have any of these cartridges, you can use undiluted white vinegar. You should soak this on the mineral deposits, but don’t run the humidifier. The vinegar will loosen the deposits, which will help flush them out.

Q: Can I use hard water in my humidifier?

A: Hard water isn’t ideal for humidifiers unless you use a water softener tablet or demineralization cartridge. This is because the minerals on hard water will turn into white dust when diffused, and it can also damage the components. The mineral deposit will also cause pink mold buildup.

Q: What happens if you don’t use distilled water in a humidifier?

A: The use of hard water in a humidifier will lead to bacterial growth on the mineral deposits. If not cleaned properly, harmful microorganisms will start to thrive in your humidifier. In the end, your humidifier will become the cause of irritation and respiratory problems. If you don’t have any choice but to use hard water, you should at least add a demineralization cartridge to your humidifier.

Q: What you should not put in a humidifier?

A: You should never put anything in your humidifier other than water. If you wish to use your humidifier as an oil diffuser, make sure that it’s designed for such a purpose. Otherwise, the oil will damage the unit’s hose, filter, and misting mechanism.

Q: Can I put lemon juice in my humidifier?

A: A few drops of lemon juice on your humidifier won’t hurt. Actually, it helps reduce congestion, and it will also deodorize your room naturally. This is much better than loading your humidifier with essential oils, especially if it’s not rated for such a purpose.

Q: How do you prevent calcium buildup in a humidifier?

A: Using demineralization cartridges or tablets, you can prevent calcium buildup in a humidifier. These items will help neutralize minerals that could accumulate inside your device.
