Humidifiers are the easiest way to bring back the moisture your home is lacking. Just like how high humidity can be bad news, low humidity can lead to dry skin and allergy irritations.
Nobody wants dry air to the point that your airways feel irritated and your skin noticeably lacks moisture. Very dry air can affect your health in many ways, especially if you suffer from asthma or any other respiratory illness. It can make these issues worse and a lot harder to manage.
Controlling indoor humidity generally makes your living conditions more comfortable. Some humidifiers offer both warm and cold mist to target temperature and humidity at the same time.
On top of being a great way to bring back moisture, humidifiers are amazing for keeping track of your home humidity levels. Oxford City Council states that the ideal range of indoor humidity is between 30 to 60 per cent. Any humidity levels below 30 per cent are too dry.
Signs that you need a humidifier at home
Prone to colds and flu
If you find that you are particularly prone to colds and flu, this could be a sign your home is lacking humidity. Higher humidity decreases the infectivity levels of common colds and flu. Bacteria particles cling to moisture, and if it hits the water vapour before you, the chances of it infecting you decrease.
Dry skin and lips
Dry skin is the easiest way to spot your home that needs moisture. Whether it's suddenly turned irritable or has been an ongoing issue, dry skin is incredibly uncomfortable. Using lotion and Vaseline may not be enough to rehydrate your skin. A humidifier can help you to retain more moisture, and reduce skin cracking and wrinkling when it's too dry.
Dry air can contribute to the intensity of your snoring. With low levels of humidity, your nose can become increasingly congested, which can restrict the air able to pass through, causing you to breathe out of your mouth. Low humidity can ultimately be the reason you’re keeping your partner up at night or vice versa.
Most plants thrive in humid environments; if you’ve found your indoor plants struggle to live for a long time, the low humidity in your home could be the issue. This also depends on the plants you have, but if your plants don’t retain moisture, a humidifier could help.

Review: "I got this originally for my houseplants. It's about 12cm tall and doesn't take up a lot of space so it's great to put amongst your plants. When it's on it's very quiet. It has two settings; one is a continuous stream and the other is intermittent. There are also 2 light settings, consistently one and the other is a sort of pulsing light. The light is warm, not too obtrusive if you want to have it on at night. It's easy to use, takes normal tap water. It also comes with 2 extra filters. It will stay on for hours, even filling the container up halfway allows it to stay on all night. The stream turns off automatically once all the water has run out. My only small complaint would be that it comes with a short USB cable (no plug), so it has to be placed near a socket."

Your humidifier FAQs answered
How does a humidifier work?
Humidifiers work by emitting water vapour into the air; this process adds moisture into your environment, which will work to relieve any dryness and irritations commonly associated with low humidity.
Are humidifiers and diffusers the same?
Humidifiers and diffusers share a few of the same processes but are by no means the same. A diffuser is typically smaller and designed to be used with aromatherapy or essential oils. Whereas, a humidifier is generally a larger device that increases moisture levels in the air and maintains a well-balanced humidity level.
Will a humidifier help with allergies?
Humidifiers can help to ease allergy symptoms and allergy-induced asthma. Keeping humidity levels well-balanced can keep nasal passages clear, giving your body a much easier time purging allergens. 2-in-1 humidifiers with air purifiers are great for killing bacteria in the air, ensuring the air we breathe is as clean as possible and free of any allergens like dust.
