We, being one of the popular blogs on water and water technology, thought of shedding some light on this and finding out if you can use purified water in a humidifier. 

Can You Use Purified Water in Humidifier

You can use purified water in a humidifier. In fact, purified water in a humidifier can help you in getting rid of the issues such as clogging, mineral deposits, and even bacterial growth. The purified water can, in essence, extend the life of your humidifier and improve its efficiency.

Yes, you can use purified water in a humidifier. In fact, it is highly recommended to use purified water in a humidifier. It can help you in prolonging the life of your humidifier by eliminating the possibility of bacterial growth, mineral deposits and clogging issues. 

The humidifier increases the humidity level of the indoor air by converting water into steam, water droplets or mist. This effectively releases the moisture into the air, and thus, you will begin feeling a bit comfortable even in hot weather. That is why the quality of the water used in the humidifier will assume a lot of importance. Any source of water that is unsuitable can result in issues such as affecting the performance of your humidifier or even damaging it. 

A purified water is the water that has been purified completely to remove all the impurities in it. The best purified water you can use in a humidifier is distilled water. So, ultimately, purified water is the best water to use in humidifiers as it is an entirely pure water with no contaminants and minerals. This will ensure that your humidifier will continue to serve you for years without any issues in terms of performance or the quality of the mist or humidity that it produces. 

How to Purify Water For A Humidifier?

You can use a few good ways to purify water for a humidifier. Some good techniques would include boiling, using a reverse osmosis technique, or distilling water. The distilled water is the best water to use in a humidifier. 

To purify the tap water for use in a humidifier, you can use any of the techniques here below –

Boil water 

Boiling the water can be the best way to make the tap water suitable for use in a humidifier. Boling removes most of the contaminants from the water and makes it clean for use in a humidifier. However, it may be noticed that boiling may not remove the micropollutants from the water. This is the reason why boiling water for use in a humidifier is not the best choice. 

Buy a water filter

You may use a water filter to purify water for consumption in a humidifier. A good water filter should be able to clean most of the minerals and other contaminants from the water and make it suitable for use in a humidifier. It is highly advisable to use a water filter that has a high micron rating. We also recommend using a filter from a reputed brand. 

Use a home water distiller

A home water distiller will keep your water free from all sorts of contaminants. The home water distiller works by boiling the water and then collecting the steam in a condenser, which converts the steam back into water. The only difference is that the water you now have is pure and best suited for your humidifier. 

Install reverse osmosis water softener

Reverse osmosis is the best choice for keeping your water pure. These filtration systems make the water flow through a semi-permeable membrane that filters out all the particles and contaminants. This will result in high-quality water that is suitable for use in a humidifier. 

Is Brita Water Distilled?

No, Brita water is not distilled. Brita filters can only filter the water but will not distil it. However, the Brita water is definitely the pure form of water which is obtained after removing the impurities from the water. It can be safely used in a humidifier. 

Brita water is pure water as the filter removes the following minerals – Chlorine, Sediment, Organic compounds, Zinc, Lead, and  Asbestos. But if you are looking for the distilled water, brita water is not your right choice. 

Can You Use Tap Water In A Humidifier?

Technically speaking, you can use tap water in a humidifier. However, it is not recommended as it can result in clogging and other issues. The tap water may also reduce the performance and life of your humidifier. 

Tap water contains a huge number of contaminants, such as minerals. It is highly recommended not to use the tap water in a humidifier if you are unaware of the condition of the water that you are using. 

Using tap water in a humidifier can have several issues with your humidifier:

  • Reduction in the performance 
  • Frequent downtime and repair 
  • Scale formation
  • Clogging 
  • Mineral deposits 
  • Respiratory irritation

Can You Use Bottled Water In A Humidifier? 

You can definitely use bottled water in a humidifier. Bottled water should be a better choice than tap water for use in a humidifier. However, before use, it may be necessary to check the mineral content in the water. 

Bottled water is quite pure and best for potable purposes. However, it may have a few minerals added to help improve the taste, which can clog the humidifier. If you are unsure, it is better to avoid using bottled water in a humidifier. Most of the humidifier manufacturers recommend using distilled water and no other types of water at all. 

Should You Put Hot or Cold Water In A Humidifier?

You should never use either hot water or cold water in a humidifier. It i;s highly recommended to use the water at the room temperature in a humidifier. Hot water in the humidifier can produce heat or steam, while cold water can make the humidifier work really hard which can reduce the lifespan of your humidifier. 

Hot water, while moving through the humidifier, can heat up the electrical and mechanical parts inside your humidifier. It can result in an increased wear and tear and ultimately result in a possible damage to the humidifier. Cold water, on the other hand, may make the humidifier to work hard to humidity your room. Since the humidifier needs to heat up the water before it can humidify the room, you would find the efficiency of the humidifier reduced to a large extent.

So, What Type Of Water Is Best For A Humidifier? 

Purified water is the best for humidifiers. Since it does not consist of any impurities, it is the right pick for use in a humidifier. Among all the different types of purified water, the distilled water is the best option for humidifiers.

Reduced mineral deposits 

Tap water can consist of minerals such as calcium, magnesium, iron and more. The use of purified water can ensure that there is a reduced clogging.
