What Should My Home or Basement Humidity Be?

If you found out your home has a humidity level of 70% from a hydrometer, you may be a little confused. Is it even that bad?

It’s surprising, but it’s actually dangerous to have your home humidity that high. Many nasty organisms can thrive in that environment and harm your health.

High humidity additionally can cause damage to your home. That’s why it’s so important to make sure your home humidity levels are under control.

Is 70% Home Humidity Bad? What should it be?

What Should My Home or Basement Humidity Be?

What should your indoor humidity level be, anyway? Well, this is something that most sources agree on. The general consensus from local governments is to keep it below 60-70%.

The reason for the range for maximum humidity is due to environmental risk factors where you live. If you live in a home that has poor ventilation, you need to ensure you keep it below 60%.

If you have quite a bit of ventilation in your home, and don’t often take long hot showers or cook without the range on, you might be OK hitting 70%.

Indoor humidity of 70% is just enough that mold can begin to take root in your home, wrecking havoc. You ideally need to figure out ways to keep the humidity down. 

How to Lower Your Home’s Humidity

There are multiple steps you can take to ensure that your dwelling’s humidity stays low. Some of these are simple, some are more difficult.

For starters, ensure your air conditioning (A/C) or HVAC system’s fan is not set to “On.” It should be kept on “Auto.” This is in hot climates the #1 cause of accidental high indoor humidity in an otherwise well ventilated house.

Next, make sure that you don’t take hot showers without a bathroom fan. If you do not have a bathroom fan, you need to invest in a dehumidifier (we recommend the LG PuriCare for a bathroom) and keep your bathroom door open while showering.

You also should ensure that you don’t cook without using your range. It may seem like it’s a harmless amount of steam, but it can add up, especially in an already humid home! 

Another thing to check is that your clothes dryer is ventilated outside. If this is incorrectly installed, it can raise your humidity to dangerous levels very quickly.

Finally, the absolute easiest way to ensure your humidity is low, is to buy a dehumidifier. A good one isn’t cheap, but it sure beats the costs of dealing with mold, and replacing damaged drywall due to high humidity. You can view our current favorite dehumidifier here.

How to Lower Your Basement’s Humidity

Basement humidity is a whole different beast! Basements not only don’t have much ventilation, they also are at an inherent disadvantage due to being underground. Water loves to pool underground.

There really isn’t another option in your basement than to purchase a dehumidifier. We recommend that every single basement has a dehumidifier.

 If the humidity gets too high in your basement, it can very quickly turn tragic. Basements can flood very easily, and a dehumidifier can help prevent those as well.
