Yes, you can use reverse osmosis water in a humidifier as a last resort, if you don’t have access to distilled water.
Is Reverse Osmosis Water Good To Use In A Humidifier?
Reverse osmosis water is water that has been purified with the reverse osmosis process. During this process, water is filtered through several filtration stages. It’s also filtered through a reverse osmosis membrane, where the majority of the dissolved solids are removed.
The most basic explanation is that water is added to the humidifier’s water tank, the machine is switched on, and water is converted into vapor and released into the air.
Humidifiers require very pure water to prevent harmful particles and contaminants from dispersing into the air during the humidification process. Pure water is also required to prevent the formation of scale inside the distiller’s water tank.
More affordable than distilled water RO water is typically cheaper to buy in bottles than distilled water. So, if you get through a lot of water in your humidifier, bottled reverse osmosis water is the cheapest long-term option.
