Our dehumidifier can actually control dust mites that are invisible to the naked eye

Dust mites are a type of mite that mainly exist in indoor dust and are difficult to see with the naked eye. Due to their widespread presence in the dust of human living environments, they can cause many allergic reactions in the human body, such as allergic asthma, allergic rhinitis, and allergic skin diseases.
The occurrence, development and persistence of symptoms of most allergic asthma are closely related to dust mite allergy: there are about 160 million bronchial asthma patients in the world, with prevalence rates ranging from 1% to 13% in various countries, and 1% to 4% in China. It is generally believed that children have a higher incidence rate than adults. In infant asthma, allergic asthma accounts for 80%, and in adult asthma, allergic asthma accounts for 40% -50%. In allergic asthma, common allergens are dust mites, cat hair, and dog hair. Dust mite is the main allergen of allergic rhinitis: allergic rhinitis is a global health problem, which is common all over the world. Its global incidence rate is 10% - 25%, and the number of patients is still increasing.
There are three related goals for dust mite intervention methods: ① reducing the total number of live mites; ② Reduce the level of mite allergens ③ Reduce human exposure to the first two. The method of achieving these three goals in a specific room is influenced by many factors: what is important is price, the ease of implementation, the importance of exposing specific sources, the nature of the chemicals used, and the potential efficiency (benefits) of using intervention methods.
Generally speaking, a simple and feasible method is to reduce indoor relative humidity. Controlling relative humidity (RH) below 50% is a commonly used method for controlling mite and its allergen levels, as surrounding relative humidity is a key factor affecting mite prevalence. Mites need to survive and obtain sufficient water from their surroundings. Experiments have shown that adult mites will die from dehydration after 5 to 11 days at a relative humidity of 40% or 50% and a temperature of 25 ℃ -34 ℃. Research has shown that mites and mite allergen levels are rarely present in dry areas such as mountainous countries or the northern part of the Middle East. Many studies have reported that seasonal fluctuations in mite and mite allergen levels are parallel to seasonal fluctuations in indoor relative humidity. In dry areas, using an evaporative cooler to increase relative humidity is sufficient to maintain the survival of mites. Recent studies have shown that the use of high-performance dehumidifiers and air conditioners indoors is both practical and effective in reducing relative humidity and mites. People may also maintain relative humidity below 50% in humid temperate zones to reduce levels of mites and their allergens. In addition, maintaining RH below 50% during the day, even if RH exceeds 2-8 hours, can effectively limit the total amount of dust mites and their allergens. When the daily RH is between 75% -85%, to completely prevent the growth of dust mites, the RH should be below 35% for at least 22 hours per day. A dehumidifier with good performance can maintain RH below 50% in temperate zones. Only this method is needed in this environment. In this low humidity environment, new carpets, mattresses, pillows, and sofas are not conducive to the growth of mites. In rooms where mites already exist, they will die in a dry environment. Over time, regular vacuuming and cleaning in these areas can reduce the accumulation of allergens. In some areas, there may be differences in levels of dominant mite and dominant mite allergens between households simply due to differences in humidity.
In short, the long-term strategy is to reduce
