How Much Hydrogen Peroxide Can I Put In My Humidifier

Hydrogen peroxide comes in different concentrations. Each has its own advantages and disadvantages. Find out what best suits your needs before buying your hydrogen peroxide solution from the store.

1% Hydrogen Peroxide

There are several uses for this substance. Most commonly, it’s used for cleaning and disinfecting surfaces in the home. 1% hydrogen peroxide is a very impressive cleaning agent because of its antibacterial properties.

It kills all bacteria and germs, giving you the peace of mind of having a clean and germ-free home. To make a 1% hydrogen peroxide solution, you need to take ¼ cup of 3% hydrogen peroxide to ½ cup of water.

The substance is very aggressive to the skin and can cause irritation and burning when touched with bare hands. Therefore, always make sure that you cover your hands well before touching the solution.

3% Hydrogen Peroxide

This is perhaps the most common and widely used form of hydrogen peroxide (H2O2) solution. Mixed with water, it’s very effective at cleaning germs. The 3% solution has a good reputation as a house cleaning and disinfecting agent.

However, it also has a good reputation as an antiseptic. So for minor cuts and scratches, the 3% solution works like a miracle.

35% Hydrogen Peroxide

35% hydrogen peroxide, also known as “food grade” hydrogen peroxide, is a very strong concentration of hydrogen peroxide. Because of this, it’s somewhat less popular than the other forms of hydrogen peroxide. It’s used in the same way as other concentrated H2O2 solutions.

However, using the 35% solution is tricky because it needs to be diluted to a 3% solution before use so that it doesn’t cause burns and damage to living tissue. To cut it to a 3% concentration, you need to add ¼ cup of hydrogen peroxide to a gallon of water.

If you add more than the above amount, you risk burning your hand.

Which Type of Peroxide is Better for a Humidifier – Pharmacy-Grade or Food-Grade?

There’s no clear answer as to whether pharmacy-grade (3% solution) or food-grade (35% solution) hydrogen peroxide is better. As mentioned earlier, the 3% solution is an excellent disinfectant and has promising healing properties.

It’s also very suitable for use in humidifiers. Therefore, this subtle variant of hydrogen peroxide can undoubtedly be used in humidifiers without any problems.

On the other hand, using the 35% solution requires more preparation than the 3% solution. It must be diluted to a 3% solution. If the strong solution comes into contact with bare skin, it can cause a severe burning sensation and have serious consequences.

For this reason, the 3% hydrogen peroxide solution is the best choice. Because even the 35% solution must be diluted to 3% before it can be used in a humidifier.


Whether cleaning the house or getting rid of a bad cough, hydrogen peroxide is an everyday necessity. This tricky chemical compound is needed in our daily lives for various purposes. Using hydrogen peroxide in a humidifier is very comforting because you don’t have to look for other alternatives.

So far, we’ve used hydrogen peroxide for house cleaning and disinfecting high-touch surfaces, but its use can reach unimaginable proportions. If we use this substance over a humidifier, we can even disinfect the house’s air.
