How To Measure Humidity Indoors? (With and Without a Hygrometer)

Nov 12,  · 1 PURCHASE A HYGROMETER One of the easiest ways to test your home's humidity level is to head to the drugstore and purchase a hygrometer or indoor humidity monitor. Place the small device in the room you want to test and follow the instructions. The hygrometer will show your home's humidity level in a percentage. To check the humidity level, leave the two thermometers for at least 3 hours. While one thermometer simply records the temperature of the room, the other will be affected by the humidity. If the humidity is low, then the cotton will dry more quickly as the moisture evaporates into the air.

Air humidity is very important for reasons we can both see and not see. Most of them, however, we can feel. If you have too high humidity in your house, then you will see condensation against the windows. A little bit of wetness around your frames might not seem like a bother, but it will mean your home is ripe for the spread of bacteria. This can be in the form of mold which leaves stains on walls, ruins furniture and can render clothing unwearable.

Moreover, it can help spread bacterial infections which really make you sick. Hlw the other hand, too low a humidity humiduty not good for you either. This can lead to dry skin, a scratchy throat and even the proliferation of the nasty how much to get a car spray painted virus. Having the optimal level of humidity will help promote overall health, keep your property in good condition and provide an ideal comfort level.

If the humidity level in your home is too high, there are a few tell tale signs. The first one is the obvious condensation against your windows. You will see water droplets dripping down the inside of your home windows indicating high humidity. This is a particular problem in cold climate hlw. There you need to keep warm inside, while the weather outside is very cold.

As warm air retains water better than cold, the moisture inside is picked up and spread out across the home. While it goes onto your windows and causes condensation, it is also going into all of the unseen parts of your house. It will go into walls, plaster and woodwork.

Over time this can lead to structural damage including rotting wooden support beams and ceiling collapse. This is not to mention the smell which high humidity can provide. As mold spreads it can go into material like curtains and clothes. You may have to throw out a wardrobe or have cherished clothing items become so stinky you can no longer wear them.

Keep an eye on family members and their health. If allergies increase it could be a sign of too high a humidity. If colds are unseasonable rampant or consistent, it could be that your home is rampant with bacteria thriving in the high humidity. Runny noses and sniffles will mean high humidity.

If the humidity in your house is too low, then this can also how to set vista back to factory settings structural problems. This is particularly the case with wood.

If you have wooden floorboards it can make the boards warp and no longer fit how to take great baby photos at home correctly.

If you have wooden furniturethen it can also warp and joints might come loose if the humidity is too low. This could be very sad if you have some inherited or antique furniture which would have otherwise lasted much longer. Check on the health of the home's inhabitants as well.

If flu symptoms persistthen it is most likely due to low humidity. Studies have shown that flu virus will fare well in this environment, making you fare much worse.

The lack of moisture in the air can lead to dry throat strep throattickly coughs and sinus trouble. The drying effect can also make your skin and eyes how many continents are there and what are they much drier, making them irritable and leading to psoriasis.

The best way to check the humidity level in your house or home is with a hygrometer rooj below. If you want to find a way to check humidity without a hygrometer, then we have another option.

We can calculate the humidity of a room by taking both the "wet" and "dry" temperatures. To do this you will need two thermometers. One will just be a regular thermometer and the other will be a regular thermometer with a water soaked piece of cotton covering the bulb.

The bulb is the spherical end of the thermometer which contains mercury and is usually colored red. Ensure that the two thermometers are kept in the same place to gauge humidity correctly. To check the humidity level, leave the two thermometers for at least 3 hours. While one thermometer simply records the temperature of the room, the other will be affected by the humidity.

If the humidity is low, then the cotton will dry more quickly as the moisture evaporates into the air. As this happens, the temperature read on the thermometer will go down.

If the humidity tto high, then the water will take humicity time to evaporate and the temperature read will be higher. To calculate the relative humidity, we need to use a relative humidity chart which we have provided below.

Take the dry temperature reading and follow it down the Y axis the vertical one on the left. Subtract the difference in temperature between the dry bulb and the wet bulb. Count along the X axis the horizontal one along the bottom the number of degrees difference. Remember that you need to include zero in your count. This is the point at which the air cannot hold any more moisture, meaning no water has evaporated from the soaked cotton.

If you sweat, the air will not be able to absorb any of your moisture, so you will remain clammy and uncomfortable. Count along the X axis from the 24 on the Y axis like so; "zero, one, two, three, four". The square you end up on is humidith. The two thermometer set up is a homemade version of something called a psychrometer. You can buy electronic versions which will do these simple calculations and chart readings automatically. If using our DIY two thermometer set up, you can make the process quicker.

The first way is to tie the two thermometers to a piece of string. Make sure they are tied on tight and the soaked cotton is held on securely.

You may need to do this with a rubber band. Swing the two thermometers in the how to check humidity level in room for about 5 minutes may seem like a long time, but it's quicker than waiting 3 or more hours.

The movement will cause the water to evaporate more quickly and give you a quicker reading for the relative humidity. The other leveel to ho it quicker to check relative humidity is even easier. Put a fan in front of the two thermometers and turn it on. The air blown by the fan will work in a similar way to swinging them around in the air. The quickest way, however, will dheck to buy the electronic psychometer we mentioned before. You can also test the humidity of your home in a more general, less accurate way.

Simply set a glass with ice cubes in the room you want to check and leave it there for about 3 minutes. Exit the room while you wait as your body heat can affect what happens to the glass.

When you go back in, hummidity a look at the glass. If there are condensation droplets on the side, then the humidity is fine. If not, then it is too dry and hw may need to invest in a humidifier.

This process won't work in a kitchen or bathroom as the humidity in these rooms are subject to too much variability. A hygrometer is a device which measures air humidity automaticallybut works in a different way to a psychrometer. There are two main types of hygrometer - analogue and digital.

The digital hygrometer will use a liquid crystal display to give the same reading. You will most likely need to calibrate your leveel before use. This is an important step so that you can test its accuracy. Like most devicesyou get what you pay for. A cheap hygrometer will give you lesser levels of accuracy compared to a more professional and expensive roim. To calibrate your hygrometer, mix half a cup of salt with a quarter cup of water until the salt is the consistency of powdery snow.

Place the hygrometer and the wet salt into a zip-lock bag, but be careful not to spill the salt on the hygrometer or it may damage it. Seal and leave out of direct sunlight in an area with a steady temperature for a number of hours usually around There is a wonderful piece of folkart which is used to gauge the humidity level in your home. A weather house determines the humidity by the expansion or contraction of a piece of hair or sometimes catgut.

When the humidity changes, the hair contracts when the air is dry or how to find area and perimeter of polygons when the air is wet which moves two figures which are housed in a little alpine cottage similar to a cuckoo clock.

If the female figure comes out of the house it will be sunny and dry and vice versa for the male. This works in a similar way to hygrometersbut the results are often much less accurate.

Whether you need to adjust the humidity in a room for a specific reason or just to be more comfortable, it can be a little tricky to get the level exactly where you want it. For a precise adjustment, use a dehumidifier to remove moisture from the air or a humidifier to add moisture.

There are also some great DIY options you can choose from, like running exhaust fans, taking cooler showers, or placing a bowl of water near a heat register to produce steam. Apply lotion to your entire body after you shower, and rub it on your hands throughout the day. The water could get into your home and contribute to the excessive humidity instead of helping solve it. Log in Social login does not work in incognito and private browsers.

Invest in a hygrometer to get a specific humidity reading in any room. For rooms that need to be kept at a specific humidity, like a wine cellar or art studio, a hygrometer will give you the fastest, most accurate reading at any given time. Shop online or at your local home improvement store to find one that fits your budget.

To ensure you get an accurate reading, place your hygrometer away from your kitchen and bathrooms. Wrap a wet piece of cotton gauze around the bottom of one of the thermometers. Set the thermometers next to each other in the room in which you need to measure the humidity.

Wait for 2 to 3 hours, then write down the temperature reading on each thermometer. Subtract the temperature from the wet thermometer from that of the dry thermometer—this is the humidity percentage for that room. Observe the windows for moisture. If the windows in any given room are foggy, or if you can see condensation on the windows, that means that the humidity inside the room is at a high level.

Also pay attention to moisture or wet stains on the walls or ceiling, as well as a stuffy feeling when you enter the room. Check the walls and ceilings for the development of mold. This is a possible sign that a room is overly humid. A dehumidifier can help remove excess moisture from the room so you can deal with the mold and keep it from returning. Keep in mind that mold is sometimes caused by another source of water, like a leaky ceiling or faucet, and may not specifically be due to excessive humidity.

The bathroom is a common place where you might notice mold developing. If this is the case, make sure to always use the exhaust fan when you shower to help filter out the humid air. The basement is another area where you might notice mold growth. Basements tend to be damp; to combat basement mold, run a dehumidifier to remove excess moisture from the air.

Pay attention to how much static you experience on a day-to-day basis. Especially in the colder months, you may start to run into excessive static due to a low level of humidity in your home. This should eliminate the static and make it easier for you to walk across carpet without getting shocked. These are other signs that a room may need some extra humidity. Method 2 of Run a dehumidifier to remove excess moisture from the air. This is the best way to control the humidity in a room, especially if that humidity level needs to be maintained regularly.

You set the level of humidity needed, and the machine will automatically shut off or turn on when needed. Use exhaust fans while cooking or doing other heat-producing activities. Most stoves come equipped with exhaust fans, as do many bathrooms.

These fans help filter out steamy air, which can quickly heat up a room. Using a ceiling fan to lower humidity will work best if the outdoor air is drier than the indoor air and if you can open windows to circulate the humid air from inside to the outside. The more enclosed a space like in a bedroom with its doors closed , the more effective this will be. Open a window if the air outside is less humid than it is inside. You can also often look online to get the current humidity reading for your particular area.

Keep doors closed to keep the humidity from other rooms out. That can also help keep a room at the right level of humidity. Depending on how large your space is, you may need more than one dehumidifier.

Take shorter, cooler showers to introduce less steam to the room. This will mainly effect the humidity in the bathroom and immediate surrounding areas. If you have a hard time showering in cold water, try making incremental changes to the temperature over time. For example, start your shower at your normal temperature, then halfway through, lower it so the water is lukewarm. At the end, turn the temperature down all the way and finish your shower with a few minutes of cold water.

Method 3 of Run a humidifier to add more moisture to the air. Humidifiers are great for rooms that tend to run dry, which can especially become a problem in colder climates or during the cooler months. Place a bowl of water close to a heating system to create steam. Fill a metal bowl with water and place it on top of a heating register or a floor vent.

As the heat warms the bowl, it will create steam. The steam will add moisture to the air. Never use a plastic bowl, as it might melt when placed on the heating register. Let your laundry air dry instead of using the dryer.

For example, if your bedroom is always dry, set up a drying rack and use it to dry your laundry. Keep the bedroom door closed to keep the new humidity in the bedroom.

Add houseplants to the room to increase the moisture in the air. When plants transpire, the water that reaches the leaves evaporates into the air, which in turn increases the humidity. Plus, plants help remove air pollutants that can cause irritation. On the flip side, if your home has excessive humidity and you own a lot of houseplants, consider removing some to help reduce the humidity level.
