If you suffer from health problems related to dry air in your home, then it’s time to consider a humidifier. It can be tempting to buy smaller humidifiers to put in all of the rooms of your home, but I strongly recommend investing in the best whole house humidifiers. They offer a lot of benefits and will help keep you and your family breathing easy.

How to Select the Best Whole House Humidifiers

The first thing that you need to consider when shopping is the coverage area that the humidifier offers. The last thing that you want to do is choose a unit that is sized too big or too small for your home. If you are torn between choosing one that is too big or one that is too small, then I recommend choosing one that is a little big larger, as you can simply run it on a lower setting.

You also need to consider how much water the humidifier can hold at one time, because you don’t want to have to be refilling it on a daily basis. This is also the time to consider how easily you can refill the water storage tank, as some are much easier to fill than others.

Whole House Humidifier Benefits

I know that a lot of people think that having multiple humidifiers in their home will make it easy to combat dry air, but I definitely think that a whole house humidifier is the better option. These appliances feature a lot of great benefits, making them an obvious choice for anyone. One of the top benefits is that they are very convenient, and once you have them installed correctly, you don’t need to worry about adjusting the humidity level like you do with smaller units.

Additionally, they help to make your home much more comfortable and ensure that you and your family are safer and healthier. Dry air can cause health problems and even spread disease. At the same time, it will damage wood floors, furniture, and instruments.

When you run a whole house humidifier, then you will find that your home is not only more comfortable, but that you have lower operating costs. When you keep your air at the right humidity, then you can more easily heat and cool your home, resulting in lower power bills.

What to Look For

There are a few attributes that will set some humidifiers apart from others on the market. I recommend that buyers look for ones that have a touch screen control panel, if possible, because these make it really easy to adjust the humidity level in your home.

Also make sure to choose a unit that has a variable speed motor so that you can turn it up and down as needed. This is especially useful if you notice that the motor tends to rattle or make a lot of noise at higher speeds, as you can simply lower the speed to reduce the problem.

Finally, make sure to look for a unit that features an automatic shutoff when it runs out of water or when it has reached your set humidity level. You do not want your humidifier to keep running when there isn’t any more water in the tank, as this can be a real hazard.

How to Use Your Whole House Humidifier

It can be tricky for some people to find the perfect sweet spot between high and low humidity in their home, but between 35 and 45 perfect is normal. This range is high enough to offer health benefits and prevent damage to wood furniture, but not so high that you are at risk for mold. Knowing this, you need to make sure to set your humidifier to raise and keep your humidity level around 40%.

I recommend checking your product guide to see how often you need to clean your new humidifier and so that you know what kind of maintenance you need. Additionally, you will need to add water on a regular basis so that your unit has something to use.


Even though whole house humidifiers are great, there are still a few things that you need to be aware of when shopping for one and installing it in your home. It’s important to be aware that you need to clean your unit on a regular basis so that you don’t deal with mold. You do not want to have mold in your humidifier and have those spores being pumped through your home or growing on your windows, walls, or floor.

Additionally, you need to make sure that you do not add too much moisture to the air in your home, as this can cause rot. Excess moisture in your home, and particularly in your attic, can cause rot, which can damage your roof. When there is too much moisture in your home, then it will build up on your windows and it can ruin the finish of your frames.
