The ideal humidity of your home should be between 30-50%. If you want to get serious and learn the exact percentage of moisture in your house, you can get a hygrometer. You can get them online for less than $10 or find them at your local hardware store.

There are many reasons why you may find yourself wanting to lower the humidity in your house.  Whatever your reason may be, we are here to help. In this article, we’ve compiled the top 10 ways to reduce moisture in a home.

10 Ways to Lower Humidity in Your Home

Use a Dehumidifier

Sometimes, the most straightforward answer is the most overlooked. If the humidity level of your home is consistently well above 50%, then it’s time to invest in a dehumidifier. Portable humidifiers are an excellent option for moisture-prone areas of the house. But if you’re up for the investment, a whole-home humidifier will be the best at tackling your moisture problem.

Utilize Your Fans

It’s easy to forget to switch on your exhaust fan before you hop in the shower. Running your exhaust fans in the restroom and kitchen will make such a noticeable difference to the moisture level of your house. Whether you’re boiling water or taking a long hot bath, it’s crucial to manage the moisture levels of your home.

If you don’t have an installed exhaust fan, a ceiling fan or portable fan will do the trick too. Fans create air circulation, and proper circulation helps stimulate evaporation. Remember that air movement is your friend. The last thing we want is a stuffy AND humid home!

Change Your Air Filters

Yes, the sad and often overlooked dirty AC filter. It turns out that air filters can significantly affect the humidity in a household. Since AC units keep your house cool, they naturally remove the moisture from the air. As a result, it’s super important to keep your unit working correctly. Dirty AC filters can cause malfunctioning and an increase in moisture levels. Remember, your AC unit is only as effective as your AC filters.

Try setting a reminder on your phone to change the filter regularly. Or if you’re quite forgetful, there are even some subscription programs that deliver fresh filters monthly to your doorstep!

Colder/Shorter Showers

It may be the least enjoyable of our suggestions, but taking shorter or colder showers is one of the most effective ways to lower the humidity in a house. Know that feeling when you get out of the shower, and everything is all foggy, and you can barely see? That’s what we are trying to avoid!

Adjusting how we shower is one of the most manageable changes we can make in our daily routine to decrease moisture levels in the home.

If you simply can’t make this sacrifice, try a low flow showerhead. Energy-efficient shower heads are designed to use less water and can even save you money on your water bill! Don’t worry; they still offer the same water pressure you’d expect from your regular shower.

Keep Your Gutters Clean

It turns out the outside of your home can significantly influence the inside humidity levels of your house. That’s why it is so vital to maintain your gutters properly.

Proper gutter maintenance can reduce the chances of excess water build-up and helps direct excess water away from your home. The last thing you want is outdoor water pooling and getting indoors. Any built-up water can significantly increase your chance of mold and lead to a whole other collection of problems.


Even if you don’t have the greenest thumb, investing in some plant friends can help absorb the humidity in your home. Ferns are a type of plant that loves sucking the moisture out of the air. They also happen to look great, which is a win-win for everybody.

The right plants will thrive under these conditions and help lower the overall humidity level in your house. They will even help improve the overall air quality of your home. But be careful! Too many plants can cause an increase in your moisture levels. So make sure to choose your plants wisely. (See a full list of plants that absorb humidity here).

Dry Your Clothes

Your typical laundry routine produces a surprising amount of moisture. Hanging clothes to dry inside your home can significantly increase the humidity levels in your home. Especially if your laundry room is not well ventilated.

Using a dryer or hanging your clothes outside is a simple way to keep the humidity level down in your home. It may add an extra step to your routine, but the benefits will outweigh the cost. Plus, if you opt for hanging them outside, you’ll be saving energy too!

Replace Your Carpet

The culprit of your high humidity levels may be your carpet. Carpets are great at adding visual appeal and cushioning, but they are also excellent at retaining moisture. If you’ve tried countless methods to decrease the humidity level in your house, it may be time to replace your carpet.

For example, basements are often the dampest area of a home and are prone to be carpeted. Keeping your carpet clean or replacing your carpet can significantly reduce your moisture levels. The type of carpet you choose is also crucial since organic materials like wool are more prone to mold growth than synthetic carpeting like nylon. If you’ve tried everything, then it might be time to invest in some new carpet or flooring.

Waterproof Your Basement

We’ve already learned that our basements are prone to being damp. Waterproofing your basement walls can significantly reduce the amount of humidity in your home. It’s common for moisture to seep in through your basement walls, especially if the walls are cement. Your basement may also be more prone to humidity if it houses your laundry room.

There are multiple benefits to waterproofing your basement. It is quite a project, though, and not everyone will have the budget to do it. Not to mention that those of us who rent will not have this option.

Proper Ventilation

A properly ventilated home is important to lowering and maintaining an optimal level of humidity in your home.

This may seem too simple, but just opening a window will help lower your home’s humidity levels. This is undoubtedly one of the easiest ways to reduce moisture in the air, but it is, unfortunately, not the most efficient. Opening your windows too much can cause you to increase your AC use, so just try to be mindful.

Final Thoughts

We depend a lot on the structural integrity fo our homes, therefore it is essential to maintain them properly. High humidity levels can cause structural damage to your home through rotting wood and deteriorating flooring. Remember that it’s not just our home health at risk, as our health is also adversely affected by too much humidity. Too much moisture can cause health problems, mold growth, musty odors, and overall discomfort.

It’s easy to have high humidity levels in the home, but the good news is that it is also easy to manage it. Through the above list, you’ll be on the path to a more comfortable and healthier home in no time.
