What Percentage Should My Humidifier Be Set At In Summer? (Find the perfect humidity)

Dry air is a common problem during the summer months. Not only can it leave your skin feeling dry and itchy, but it can also aggravate respiratory problems and make you more susceptible to infection.

A humidifier can help combat the effects of dry air by adding moisture to the air.

But what percentage should your humidifier be set at in order to get the most benefit?

Here is a guide on how to find the perfect humidity level for you this summer!

How to find the perfect humidity level for you this summer

You know that feeling when you walk into a room and it’s just a bit too stuffy? Or when your hair is starting to frizz because of the humidity? Finding the perfect humidity level for you this summer is all about striking the right balance. If it’s too humid, you’ll feel sticky and uncomfortable. But if it’s too dry, your skin will start to feel tight and your sinuses will get irritated.

So how can you find that happy medium?

A humidity level between 30% and 50% is generally considered ideal. But depending on the temperature and how dry it is outside, you may want to adjust your humidifier accordingly.

If it’s a particularly hot and muggy day, you may want to set your humidifier to a lower setting.

And if it’s a dry and sunny day, you may want to crank it up a bit.

  • As a general rule of thumb, you should start by setting your humidifier to the middle of the range and then adjust as needed. If you find that your skin is still feeling dry after a few days, try increasing the humidity level. And if you start to feel sticky or uncomfortable, turn it down a notch.
  • One way to gauge the humidity level in your home is to invest in a hygrometer. This little tool measures the amount of water vapor in the air, so you’ll be able to tell at a glance whether the air is too moist or too dry.
