Too Humid or Dry: Controlling the Air in Your Home

Home is where most people spend a big chunk of their time, and where valuable belongings are kept. Depending on the climate where you live, and how your place is designed, dealing with severe dryness or humidity can prove to be a challenge.

Not to worry though - there are solutions to solve these obstacles, and one can start with using a RuuviTag. Nowadays we have access to technology that can be easily harnessed to create a more comfortable and enjoyable living environment. RuuviTag helps you to monitor your home’s humidity levels with a mobile app.

It is important to understand the threats posed by extreme air condition, and how to deal with them effectively. For example, in the case of excessive humidity, ventilation is of course a great ally. On the other hand, if you seek to avoid dry air, caulking and keeping windows closed is what you should aim for. Indeed, when cold air enters your home, it heats up, thus reducing overall humidity. Science!

Damages due to dry air and how to avoid them

A prominent issue that people typically associate with dry air is how it can wreak havoc on one’s skin - dry air can cause itchy or cracked skin, chapped lips, and easily irritable sinuses. These are not only annoying, they are also unhealthy. On top of that, dryness in the air damages many things in your home, particularly items that are crafted out of wood, such as furniture, home decor items or musical instruments, all of which can be worn down at a faster rate due to dry air. Ever noticed how much hardwood floors creak in the winter?

RuuviTag sensor can be used to protect musical instruments

In order to prevent these situations, one solution is to anticipate the problem – utilise a humidifier in your home to balance the humidity and protect items, and moisturise your skin regularly to prevent irritation and chapped lips. Another solution is to avoid excessive use of a heater in the winter, as this can cause the air to become drier, and is not a very eco-friendly way to live in the long term. Not to mention that cold air can cause a diminution in humidity if it manages to seep into your home whilst a heater is turned on. Other solutions to combat overly dry air in your home is to dry your wet clothes on the radiator, provided that you’re careful not to damage your clothing and you take precautions to make sure that the radiator does not catch fire. Boiling water when cooking can also help add more water to the air, which increases humidity levels.

How do you know the levels are correct for you, your family and your home? The user-friendly Ruuvi Station, connected to your Ruuvi Bluetooth sensor, analyses the humidity levels in your home and shares the data in a convenient, fuss-free manner.

With this technology, maintaining the humidity levels of each room in your home has never been easier, allowing you to adapt to any unwanted changes in the air’s dryness right away. It is extremely versatile and can be used in any situation that calls for monitoring cool air, even inside a cool box!

Humidity related issues

On the other hand, excessive humidity can also cause a myriad of problems, for both objects and people. Anyone who resides in a tropical climate is familiar with the struggle, and fighting against it requires good habits and regular monitoring. Southern Europe during the summer, or Southeast Asia all year round, are places where extreme humidity is an issue. The main problems caused by too much moisture in the air are wet insulation, mold, rotting wood in the walls, and peeling paint. This is especially true for poorly ventilated bathrooms or kitchens.

A common solution - in moderation -  is air conditioning. By turning on your AC once in a while, even when cooling would not be necessarily needed, you can greatly reduce the air humidity level in your home. Watch out for the electric bill though! Another technological solution is a dehumidifier. This home appliance is particularly popular in countries such as Hong Kong, and have proven to be very effective in getting rid of excessive moisture in the air. Prices vary greatly depending on quality, but cheaper ones may start around 100€.

If neither of these options are available to you, then ventilating your home the good old fashioned way is your best bet. Opening up the windows is a quick, cost-free and painless way to guarantee air flow - although this may allow for cold or hot air to come in.

Another thing to keep in mind is to limit time spent in hot showers, as enjoyable as they are, as the steam that arises from the hot water meeting cold air can contribute to increasing humidity levels in your bathroom.

It’s important that you factor in certain criteria, such as the country you live in or the materials your home is made out of, before you approach a method of regulating moisture in the air.

Depending on what you are aiming for, the application can be set in order to send you alerts when moisture levels go above or below a certain threshold. All you need to do is set your parameters and decide at which percentage a message should then be sent to your smartphone.

In Conclusion

It is important to control the levels of humidity in your home, as it is a fairly simple task that both your wallet and health will appreciate. Taking care of this will result in a more enjoyable environment for everybody and will help maintain the quality of your belongings. Technology can be put to excellent use in order to facilitate the comfort and ease that we can experience in life. The RuuviTag and its accompanying app are great partners for this.
