A few words about smog
What is it composed of? Is it dangerous?
If you get up with stuffy nose, have runny nose, bouts of sneezing or tearing conjunctivitis – you probably suffer from an allergy. Almost everyone has at least one allergic reaction in their life. The number of allergenic substances grows each year, the number of ill people alike. Currently, more than half of the population of Poland complains about allergic diseases.
Allergy is an abnormal, hypersensitive reaction of the immune system to foreign substances called allergens. The environment factors that cause an allergy are harmless themselves but the immune system of the patient considers them dangerous and produces a reaction that aims at neutralizing allergens and removing them from the body. Such reaction is the symptoms of allergy.
Allergy reactions, depending on the allergen, can have various from, such as rhinitis, conjunctivitis, itching, bouts of sneezing and breathing troubles as well as eczemas and wheals with anaphylaxis and death in extreme cases. The symptoms usually concern one organ or issue. Most frequently these include nose, eyes, skin, respiratory tract and digestive system.
Although in most cases allergy is not a direct threat for a person, its annoying symptoms significantly decrease the quality and comfort of living. There are several treatments available for allergies, including but not limited to immunotherapy (desensitization) and the use of medicines limiting or completely eliminating the symptoms of allergic reaction. The method which is most frequently recommended to people suffering from allergies is to remove the allergen from their environment. Unfortunately, with allergy to plant pollens, avoiding the allergen is much more difficult.
In Poland the pollination season usually starts in January and lasts even until November. The highest pollen concentration is recorded between May and September. However, allergic reactions can occur all year long. Grass, birch and mugwort pollens are the most annoying for people suffering from allergies.
The size of pollen of those and other plants is usually from 5 to 100 μm, with the majority being approx. 40 μm large. In comparison, smog particles can be as small as 0.1 μm, which shows that plant pollens can be filtered much better. And this brings us an easy way to get the long-awaited relief form allergy when staying at home.
Anti-smog and anti-allergic filter removes particles as small as 0.5 μm – which is 10 times less than the smallest pollens. Filtration efficiency for pollens of approximately 40 μm is almost hundred percent.
The use of an anti-allergic air filter is therefore the easiest and the most universal way of protecting oneself against troublesome symptoms of allergy in the rooms where one spends most of their time. At the same time the filter removes hazardous substances and enables optimum “ventilation” without opening the windows. This way a person’s exposure to allergens is efficiently limited. The use of the filter also slows down proliferation of house dust mites.
