Humidifiers: Improve Your Home’s Air Quality for Health

As winter approaches and temperatures drop, our quest for warmth and comfort becomes universal. Humidifiers, which can also be in the form of houseplants, play a vital role in creating a cosy indoor environment during the colder months. These devices work by adding moisture to the air, a process called humidification. This not only imparts a comforting warmth but also offers numerous health benefits. However, like any technology, humidifiers have their considerations. This article is a comprehensive guide to humidifiers, exploring their advantages and potential concerns.

Types of Humidifiers

Humidifiers come in several different types, each with its unique features and benefits. Here’s an overview of the most common types of humidifiers:

Central Air Humidifiers

These humidifiers are built into a home or office to add moisture to that space. They have connections to the heating, ventilation, and air conditioning systems to humidify the entire house. Central air humidifiers are a convenient choice for maintaining consistent humidity levels in larger spaces.

Impeller Humidifiers

Impeller humidifiers are considered child-friendly because they operate without heating the water. Instead, they use a fast-spinning disc to create tiny water droplets that are released into the air as a cool mist. It means there’s no hot water or steam involved, reducing the risk of burns and making them safer for children to be around.

Steam Vaporisers

Steam vaporisers or warm-mist humidifiers produce steam, which cools before exiting the machine, using power. It boils water to create steam. If you have kids, do not purchase this humidifier. If a steam vaporiser’s hot water spills, it could burn you. 

Ultrasonic Humidifiers

These humidifiers use sound waves to release a cold mist. These leave water vaporising via vibrations rather than electricity. Its surface vibrates at a very high speed (1.65 million times/sec) and has a small water storage tank. 

Evaporators

These devices produce humidity utilising conductive and convective heat transfer. It uses a fan to blow air through a wet wick, filter, or belt. As the air passes through, it picks up moisture and distributes it into the room. These devices are cost-effective and suitable for larger areas.

Cool Mist Humidifiers

Cool mist humidifiers work by releasing room temperature or cool mist into the air. They are safer to use in households with children and are more energy-efficient. These are further categorised into two subtypes:

  • Impeller Humidifiers: These use a rotating disk to produce a fine mist.
  • Ultrasonic Humidifiers: As mentioned earlier, these use ultrasonic vibrations to create a cool mist.

Travel Humidifiers

Travel humidifiers are designed to be compact and portable, making them friendly for travellers. They work by adding moisture to the air, which is especially useful in dry hotel rooms or during long flights where the air can become very dry. By maintaining a comfortable humidity level, these humidifiers can help travellers avoid issues like dry skin, dry throat, and discomfort caused by dry air, ensuring a more pleasant and healthier travel experience. Their small size and ease of use make them convenient companions for those on the go.

Summary

Humidifiers come in various types, each offering unique features and advantages. Central Air Humidifiers are integrated into homes and offices, connecting to HVAC systems to humidify entire spaces. Impeller Humidifiers are child-friendly, using a rotating disc to disperse a cold mist. Steam Vaporizers produce warm mist but can be risky around children due to hot water. Ultrasonic Humidifiers employ sound waves to release a cold mist. Evaporators use heat transfer with a wet wick or filter to distribute moisture effectively. Cool Mist Humidifiers, including Impeller and Ultrasonic types, release room-temperature mist, which is ideal for households with children. Travel Humidifiers offer portability for maintaining comfort while on the move.

Benefits of Humidifiers 

Humidifiers offer a multitude of benefits, not only for your home but also for your well-being. Such as:

Benefits Your Home

Moisture from a humidifier may benefit the interior environment of your house. It may make your wood floors or wooden furniture last longer. Houseplants thrive in a more humid environment, which can benefit both your indoor air quality and your greenery. Moreover, humidity can also prevent wallpapers from cracking and static electricity from accumulating. 

Keeps Skin, Lips, and Hair Moist

For many, winter months mean dry skin, lips and hair. You can avoid this by getting a humidifier that adds moisture to the air and helps to ease cracked or dry skin. 

Reduces Snoring

Increasing the amount of moisture in the air can also reduce snoring. Snoring results from a person’s dry airways. If the airways are sufficiently lubricated, it will help reduce snoring. Humidifiers can also provide relief from nasal congestion, sinusitis, and cold symptoms, making breathing more comfortable. 

Prevents Influenza

Humidifiers may lower the chance of contracting the flu, according to studies. Studies have shown that humidity levels higher than 40% destroy virus particles, significantly reducing their infectious potential. Humidifiers help maintain optimal humidity levels, reducing the risk of airborne pollutants and allergens.

Summary

Within your home, humidifiers create a favourable environment for houseplants, extending the life of wooden furniture and preventing wallpaper cracks. Moreover, they keep skin, lips, and hair moist during dry winter months. Humidifiers can reduce snoring by lubricating airways and ease breathing discomfort caused by congestion and cold symptoms. Additionally, studies suggest they lower the risk of contracting influenza by reducing the infectious potential of virus particles through optimal humidity levels above 40%.

Possible Risks

Dirty Humidifiers

Keeping your humidifier clean is of utmost importance. If a humidifier isn’t cleaned regularly (ideally every 3 to 5 days), it can become a breeding ground for viruses and bacteria. When these microorganisms are released into the air, they can lead to various health issues, potentially causing infectious diseases and triggering lung illnesses. To prevent this, make cleaning your humidifier a routine task.

Too Damp Air

Maintaining the right level of humidity is vital to a healthy indoor environment. When humidity levels are too high (above 60%), it can create problems. Excessive moisture provides an ideal setting for common allergens like dust mites and mould to thrive, which can be troublesome. To ensure a comfortable and safe atmosphere, it’s advisable to keep indoor humidity levels between 30% and 50%. Using a hygrometer can help you monitor and maintain the proper humidity.

Asthma and Allergies

Research has suggested a link between the use of humidifiers and an increased risk of asthma in children. Additionally, excessive humidity can exacerbate existing allergies and make it harder to breathe. To minimise these risks, it’s essential to strike a balance with humidity levels in your home. Maintaining the recommended indoor humidity range of 30-50% is vital for optimal respiratory health, particularly for children, as it can help reduce the likelihood of asthma and allergy-related issues.

Summary

Maintaining a clean humidifier is essential to avoid health risks associated with airborne viruses and bacteria. Regular cleaning, ideally every 3 to 5 days, prevents the release of these harmful microorganisms, which can lead to infectious diseases and lung problems. Moreover, maintaining indoor humidity levels within the range of 30% to 50% is crucial to prevent allergens from thriving in overly damp conditions. Excessive humidity above 60% can make breathing difficult and worsen allergies. By striking the right balance in humidity, especially for children, you can reduce the risk of asthma and allergy-related complications.

HealthifyMe Suggestion

In only a few minutes, you can make your own humidifier. A plastic tub, a bath towel, a small fan, and a chair are all you need. Place the chair against a wall near an electrical outlet. Position the tub so that it is at the back of the chair. Add a few inches of water to the tub. Place one end of the towel in the water and the other over the back of the chair. Set the fan to low and place it on the seat of the chair, facing the towel. As the towel absorbs water from the tub, the fan will blow air across the damp surface, quickly raising the moisture content of the air around you.

The Final Word

Humidifiers are household devices meticulously designed to augment air moisture within enclosed spaces or rooms. They release water vapour into their surroundings, effectively elevating the overall humidity. Their efficacy is particularly noteworthy in addressing issues such as dry skin, nasal discomfort, throat irritation, and chapped lips, all of which are common inconveniences arising from low indoor humidity levels. However, remember to keep track of the humidity levels, clean the device often, change its filters, change its water regularly and practise caution whenever children are near it.
