You probably only think of humidifiers as the device you turn on when you are down with a cold. But did you know that they can play a significant role in saving your gorgeous hardwood flooring?
A humidifier can protect your hardwood floor from low humidity if you live in a dry or cold environment. Indoor humidity levels below 35% can create gaps in your hardwood floor and even cause it to split. A humidifier can help protect hardwood from seasonal humidity fluctuations.
So, is a humidifier really necessary for hardwood floors? What is the best humidifier for hardwood floors? Let’s discuss.
Is a Humidifier Necessary for Hardwood Floors?

Whether or not your hardwood needs a humidifier depends on your climate and indoor humidity level. One thing to keep in mind about wood is that it is hygroscopic and behaves similarly to our skin. Meaning, that in a humid environment, it absorbs moisture from its surroundings and, on the contrary, loses moisture in a dry environment.
When wood dries out, it changes its shape and contracts, leaving gaps between hardwood boards. Eventually, the wood will crack and become brittle if left in low humidity for too long. Dry winters or even air conditioners can drop indoor humidity levels and negatively impact the wood. Other contributing factors to low humidity levels are indoor heaters, furnaces and fireplaces that dry out the moisture as they heat the air.
Using a humidifier is necessary to maintain the ideal humidity for hardwood floors in dry weather. It adds moisture to the air and protects the hardwood from gapping, splitting or damages on the hardwood finish.
What is the Best Humidity for Hardwood Floors?

The recommended humidity level for hardwood floors, which is the same as the recommended humidity level for your body, is between 38 percent and 42 percent. However, the humidity level between 35%-50% is also considered ideal. You can use a humidistat or a hydrometer to measure the humidity level in your home. It is crucial to observe and maintain a healthy humidity level to maintain your physical and hardwood floor’s health.
Besides humidity, indoor temperature also influences hardwood floors, with the ideal temperature standing at 60º to 80º Fahrenheit. Maintaining a consistent temperature and humidity throughout the year is key to minimizing any shrinkage or expansion of your wood floors and furniture. Experts recommend keeping humidity within five percent fluctuation between wet and dry seasons.
5 Signs Your Hardwood Floor is Too Dry

If the indoor humidity in your home is below the recommended level, it can damage your hardwood floors. If you face one or more of the symptoms mentioned below, you need a humidifier to increase your indoor humidity.
Here are a few signs telling you that your hardwood floor is too dry –
- There are gaps between your hardwood boards.
- The wood on your floor has developed cracks and splinters.
- Your hardwood floor finish is damaged and looks aged.
- There are wood splits down the grain of the wood.
- Your floor makes a cracking noise when you step on it.
Which Type of Humidifier is Best for Hardwood Floors?

When determining which type of humidifier is best for hardwood floors, you need to think about the different options across different scopes. For example, you will find humidifiers of different sizes or mechanisms.
Let’s explore different types of humidifiers to make the most educated choice for hardwood floors –
Whole-house humidifier
This is the one-stop solution for homeowners who have wooden floors and furniture all around the house. But of course, these humidifiers are more expensive in comparison to the single room ones. The installation is also more permanent, like your radiator or furnace.
The biggest advantage you get with a whole-house humidifier is that they are automatic and will switch on or off when they sense fluctuation in the humidity. They are usually connected to the waterline, so you don’t need to worry about refilling.
Single room humidifier
These are ideal if you have hardwood floorings in particular areas of the house. Most people use single-room humidifiers when they are ill, making these more popular in the market. These are usually portable, so you can easily move them around the house. Also, they are cheaper in comparison, making them perfect if you live somewhere with relatively high humidity around the year and dry weather for only a short period.
Multi-room humidifier
Multi-room humidifiers have a similar function to single room humidifiers — the main difference being their capacity. These can usually cover a larger area. You can use them for multiple rooms if you leave the door open.
Warm-mist humidifier
The warm mist humidifier is the most common type of humidifier that heats water to convert it into vapor. The vaporized water is then released into the room to increase the moisture level. It uses the most basic and oldest technology to add moisture.
The main disadvantage of this technology is that it can get boiling hot and pose risks to your family members. Also, it is less energy efficient than other humidifiers.
Cool-mist humidifier
Cool mist humidifiers use evaporative or ultrasonic technology to get the water out of the machine and into the air. It does not heat the water, making it relatively safer than warm mist humidifiers. The downside of this technology is that it can often create a puddle of water. It also uses wicks that you need to replace regularly.
