It is probably not a secret for anyone that the fungus that appears on the walls due to high humidity is extremely dangerous for health! And, if you notice a black spot of mold in your home, then you need to not only get rid of it, but take care of creating a normal microclimate in the room. It is for these purposes that the dehumidifier for the house and apartment serves.
If you do not purchase this device, then the cleaned mold will still return, and quickly enough. But, not only the fungus is a factor that undermines health. Let’s take a closer look at what’s what, since excessive humidity is no joke.
Why is the fungus on the walls so dangerous to health?
If you see a stain on the wall, it means that there is already too much fungus. And the air is literally teeming with active spores.
Fungus spores are present in almost every room, but under unfavorable conditions for them, which means, with normal humidity, they are in a state of hibernation. The norm is 50-60%, but as soon as the pendulum swings to 70%, the fungi begin to move into the active phase and multiply at an incredible speed, releasing enzymes that destroy everything in their path.
Not only do they spoil the appearance of things, they also enter the body with a sigh, destroying the DNA of the cell! They weaken the immune system and sores begin to fall on a person, as if from a cornucopia, while every day the body accumulates toxic waste products of their vital activity, and this is a real poison that can even provoke oncology. Children, the elderly and people with congenital or acquired respiratory diseases, such as:
- allergic rhinitis
- Chronic bronchitis
Therefore, as you understand, removing a mold stain is just an attempt to hide the consequences. And you need to overcome the root cause, namely, to regulate healthy humidity. But, you must also understand that not only a fungal infection threatens your well-being. The matter is much more global.
What are the consequences of high humidity?
The most elementary: a constant chilly feeling and coldness. Even if the temperature on the thermometer shows that in all respects the apartment should be warm, but you are still cold, then most likely it is a matter of humidity. You can, of course, wear a warm sweater, but what about the bed, which seems to be dry, but at the same time too cold?
But that’s not all! The most insidious thing about high humidity is that it disrupts the natural metabolism of a person, forcing organs to work for wear and tear. How? And so here: a normal body should receive 2-3 liters of moisture per day inside, and output about 1 liter. But, if a person is constantly in a room with excessive humidity, then he involuntarily absorbs much more, and the body is simply not able to remove so much. Therefore, the remnants of moisture settle in the tissues, which makes it difficult for the cardiac system, excretory and circulatory!
So much for the increased risk of heart attacks, kidney and liver diseases, and other life-shortening delights.
Food products that can lie for two or three days in a normal environment (the same bread, for example), spoil too quickly in a humid environment. Literally in just a day, a green coating forms on the bakery product and it has to be thrown away, since it is impossible to use a product on which at least one small speck has appeared: it is already soaked through with spores that are simply invisible to the eye. And if you cut off the damaged area, nothing will change. Bread will still be with fungi inside.
And, of course, a humid environment can spoil furniture, paintings, wooden floors … But, compared to the harm done to health every second, these material losses are mere trifles.
What instruments can be used to measure humidity
The scary thing is that the high humidity is not particularly felt. If the air is dry, it becomes difficult to breathe, the skin begins to peel off, the hair breaks, the mucous membranes of the eyes dry up. But you don’t feel moisture for the time being and you attribute such effects as chilliness to completely extraneous things.
If your home is located near the sea or a reservoir, or on the ground floor, or the ventilation system is not brought to mind, then you should purchase a special device and make sure what kind of microclimate is in the house at the moment. The device is called a hygrometer and has many modifications:
Their prices are different. The more modern and accurate the device, the more expensive it is. By and large, the humidity in the apartment does not need to be measured every day, this is not a production room, where the slightest deviation can become critical. Therefore, you can use the old and proven method, for which you need to have only an ordinary glass and a refrigerator.
Fill the glass with water, without adding 2-3 cm to the top and place it in the refrigerator. After about 5 hours, when the water temperature drops to 5 degrees, pull it out and put it in a place away from heat sources (for example, away from the battery). And now just watch what happens to your glass.
If the air in the room is dry: the edge first fogs up, but dries completely within 7-10 minutes.
If the air is excessively humid: condensation forms on the edge and begins to drip literally in drops after the same 7-10 minutes.
But if the climate is normal, then the edge will be just wet, without any large drops and will dry no earlier than in 25-30 minutes.
What causes high humidity and how to deal with it
In addition to purchasing a special dehumidifier, additional measures will need to be taken to prevent the accumulation of excess moisture. So, what factors lead to excessive humidity in the room?
- Insufficient ventilation of the room, which may be due to improper installation of plastic windows and roof
- Low plinth and thin external walls that are not additionally insulated
- Small kitchen with a small window and no extractor fan
- Lack of extractor in the bathroom and toilet
- Too frequent cooking in the kitchen, which is accompanied by a huge vaporization, but at the same time – the windows are closed. Then moisture gradually begins to accumulate in the walls, which eventually leads to fungus.
It is imperative to deal with this and the first step is to purchase a special dehumidifier. But, do not forget that the dehumidifier fights only with the consequences, and at the same time draws electricity. Therefore, you definitely need to try to eliminate the root cause, at least a little.
Naturally, you cannot move your house from a damp lowland. But to insulate the basement, make a good blind area and a waterproof coat is quite realistic. Then the dehumidifier will not have to be turned on too often.
How a dehumidifier works and how it works
It has a very simple principle. The device captures the air that enters the condenser, the temperature of which is lower than in the room. And from this, the water in the gaseous state turns into condensate and flows into the tank, and the air returns back to the room, passing through the heating radiator. That is, the room is also additionally warmed up, which is necessary, since a humid room is always cooler than with a normal balance of dryness.
Choosing an air dryer: what types are there?
Dehumidifiers are industrial, for swimming pools and household. The first two options are of no interest to us, since these are huge and very expensive colossus and for living quarters we only need a household dehumidifier, the price of which is quite acceptable and the coverage range of cubic capacity is not very large. For a day, such a device is able to remove 12-25 liters of excess moisture, and this, you see, is a rather impressive figure.
But they differ in their characteristics and designs, so before you decide to buy, you need to find out everything for sure. Moreover, if increased moisture is an eternal companion of your home, and you cannot lower it by any means, then you will have to buy two types of dehumidifiers.
Let’s say the best option is a condensing dryer that works on the principle of an air conditioner. As already described above, it absorbs moist air and gives out dry air. But its trouble is that it cannot be used in any way at sub-zero temperatures! And this means that in countries with a harsh climate and long winters, this option is a seasonal thing.
They used it in the summer and in the off-season, and for the winter it will be necessary to use another dehumidifier – a sorbent type. Air, getting into it, passes through a special composition that retains this moisture, that is, it is a kind of desiccant. But, sorbents need to be changed regularly, which is why they are unprofitable for year-round use.
There is another type of dehumidifiers that work on the principle of air exchange, otherwise – assimilation. They bring humid air directly to the street, and constantly fresh air is driven inside. But this is a very expensive pleasure, since such a device must work constantly. For an apartment, this is an unfortunate option, as it turns out to be too expensive in terms of electricity consumption.
What to look for when buying
Noise level: the lower it is, the more comfortable you will feel. Remember that the optimal range is 40-50 decibels. If it is more, it will begin to affect the nervous system with a belt. That is, you treat one, and cripple the other. It is better to overpay a little right away, but buy a model that is safe in this regard.
Power: the more powerful the device, the faster it will dry the area. And although it consumes more energy, but in the end, the savings will still be greater, since it copes with its task much faster than low-power models. And the service life of such dehumidifiers is longer.
Air exchange range: it is specified in the device parameters. But in order to understand which one is optimal for you, you will need to calculate the volume of the room. To do this, you need to multiply the area of the room by the height of the ceilings. And already based on this figure, look at the technical characteristics. The number of air exchange levels should be 3-4 times greater than the volume of the room. No more, as this is fraught with the fact that you will dry out the air. Also, do not take less, as there will be no special meaning in it.
