Just as the name suggests, a mini dehumidifier is a small machine that lowers the humidity level in a space. Mini connotes a small size unit that can be easily moved and used with very little difficulty. Humidity does more than make the indoor environment uncomfortable, it promotes the growth of dust mites, mould, and mildew- common triggers of allergies. Dust mites, mould, and mildew grow readily in “wetter” areas of the house, like kitchens, basements, and bathrooms. Allergy sufferers may experience itching and watering eyes, sneezing, wheezing, skin rashes/irritation, and possibly even problems breathing. In fact, high humidity has been isolated as a risk factor for asthma.
A mini-dehumidifier is often used for more than allergy reduction. Leaks and plumbing accidents can cause water damage and leave behind mould and persistent moisture. Water stains may warn you of an unnoticed leak. This may be accompanied by small black spots that indicate the growth of mould. Another indication of excess moisture is the collection of condensation on windows.
As mentioned earlier, a mini dehumidifier is a simple and convenient solution for allergies. Additionally, they can help to eliminate musty smells and keep mould from forming on fabrics and clothes. Interestingly, a mini-dehumidifier can also help foods stay crunchy and edible for longer, as humidity causes breads and cereals to go stale quickly. Likewise, dryer air can be protective to metal in electronics and tools, preventing rusting. Lastly, you may find that your clothes dry quicker and you need to run the air conditioner less, resulting in electricity savings. If you want to know how your mini-dehumidifier works to reduce humidity, the below has a great explanation.
There are a few factors to consider before purchasing a dehumidifier. First of all, you should determine the true humidity level in the home. A hygrometer can help measure the relative humidity. Relative humidity is a measure of the highest levels of water vapour in the air. The scale maximum is 100 %, a case where it may be raining. Levels below 30 % will feel noticeably dry. Any number above 50 % generally feels uncomfortable. The optimum level is 35-40 %. Next, you should consider the size of the area requiring dehumidification. If you find that only part of the home, as in the usual high-moisture areas, or perhaps even the site of water damage- has a high level of relative humidity, you may opt to get a mini-dehumidifier. Alternatively, if the entire home or building is humid, you can find a larger capacity unit. The strength of dehumidifiers is measured by how many pints of water can be extracted in 24 hours for a given square footage. The range of capacity ratings general run from 30- 60+ pints. The higher capacity rating are better for places that are wetter.
Dehumidifiers also come with a range of additional features for convenient use. Some have a built-in measurement tool for relative humidity. Others are able to turn off on their own. You can also opt for a model that will use a humidistat to automatically adjust the necessary level of dehumidification.
Most people will do well with a mini-dehumidifier because it can taken from room to room as required and is appropriate for travel use. If and when you determine that you can benefit from purchasing one, scour the internet for reviews of machines that fit your budget and needs.
