Why there are problems with air in the house?

There may be sources of pollution in the room that constantly emit harmful gases or particles into the air, they can be the reason for poor air quality. If there is no ventilation in the house or it does not work well, then there is not enough fresh air in the rooms to remove pollutants. High temperature and humidity can also cause some contamination.

Where do the main air pollutants come from?

Every home can contain a large number of sources of air pollution, such as building and decoration materials, furniture, plastics, floor coverings, wax, aerosol cans, carpets, cleaning and detergents, and personal care products. The presence of carbon dioxide in a room is the result of human breathing. Other indoor pollutants: carbon monoxide (combustion product of household gas when heating a house or cooking on a gas stove, etc.), radon, nitrogen dioxide, tobacco, biological pollutants (waste products of mites, microbes, fungi) and many others. Depending on the concentration of pollutants and their chemical composition, they affect the health of people in the room in a variety of ways.

Some things, such as building or decoration materials, furniture, air fresheners, can be permanent sources of air pollution, while others, if they are associated with one or another human activity in the room, can appear from time to time.

CO2 air scrubbers for cleanrooms keep the air clean from unwanted airborne particles when it is needed the most. Cleanrooms can be surgery rooms, part of specialized industrial production, scientific research or biotechnology and medicine premises https://www.alfaintek.com/products/air-scrubber/cleanrooms.html.

Level of carbon dioxide (CO2)

By measuring the maximum level of carbon dioxide, we indirectly check the quality of ventilation, as well as the level of other pollutants in the indoor air. However, it must be remembered that this is not always true for premises located in large cities, because the level of carbon dioxide in a room depends on the level of carbon dioxide in the atmosphere, and in large cities it can be greatly increased. The most comfortable for the person in the room can be considered the level of CO2  is not higher then 600 ppm (0.6%), the nearer the level of carbon dioxide in the room to the normal atmospheric pressure, the better the person feels. If the carbon dioxide level in the office approaches 1000 ppm (0.1%), this may indicate that the ventilation system is poorly balanced, too little air is supplied to the room, or the ambient air is too heavily contaminated with CO2, which prevents the ventilation systems from maintaining low levels of carbon dioxide. In this case, it is necessary to install special devices-absorbers of carbon dioxide, which remove excess carbon dioxide from the room air and, together with the ventilation system, will maintain the air quality at a good level.

Removing CO2 from the demineralized water storage tanks may be done by using CO2 Scrubbers and CO2 Tank Breather Filters. CO2 must be removed from the airflow during emptying process. CO2 Scrubber or CO2 Tank Breather Filter will also keep low conductivity and stabilize pH so that the highest water quality may be achieved https://www.alfaintek.com/products/tank-co2-absorber.html.

Which air purifier to choose

The air purifier should purify it and not add by-products, which can only be done by mechanical and absorption type purifiers. The best results are achieved when using a HEPA filter and special type of activated carbon. They are the safest cleaners, especially for allergy sufferers and asthma sufferers and children.

In order for the air purification to be effective, you first need to decide where you will install the purifier, then you should choose a purifier that is able to drive the air in the room through itself at least 3, and preferably 5 or more times.

In order to understand how to do this, first calculate the volume of the room for which you are choosing an air purifier.

To do this, multiply the area of ​​the room by the height of the ceiling - and you get the volume of the room in cubic meters.

Find out the airflow per hour offered by the manufacturer of this purifier and divide by the volume of your room.

You will get a figure that will show you how many times this purifier can pass the air in your room through itself in one hour, purifying it:

• If you just want to clean the air from household pollution, then this figure should be at least 2.             

• To purify the air from tobacco smoke, this figure must be at least 5.             

• The more times your chosen purifier treats your air, the more efficiently it will work.             

It should be noted that a properly selected and well-executed air purifier is able to significantly improve the indoor air.

Compressor intake filters provides non-corrosive and purified air for industrial air compressor appliances and eliminates up to 100% of particulates and corrosive species entering the compressor https://www.alfaintek.com/products/compressor-intake-filter-system.html.

Air purifiers

As you know, a modern person spends more than 90% of his time in rooms where the air quality is far from perfect. Scientists say that the air in the homes where we live and the offices where we work is several times more polluted than the atmosphere in cities.

This raises a legitimate question: "What to do?", Because it is already clear that low air quality negatively affects the human body. Contaminating substances that are in the indoor air can cause new diseases or exacerbate existing ones. In this case, people suffering from asthma and allergies are especially vulnerable. Children who grow up in homes with poor air quality are much more likely to develop asthma in the future.

The best way to get rid of air pollution in your home is to install good quality ventilation. But this is not always possible. In addition, ventilation can supply clean air from the outside only in ecologically clean places. In practice, it turns out that the air in large cities is polluted, so it is useless to supply it in large quantities to the premises. How then to proceed?

There is only one answer - the air must be purified. It is to cleanse, not change its content by adding one or another ingredient. Air is not a soup to which you can add something, but something not, depending on your desire.

Clean air has a completely definite composition with respect to nitrogen, oxygen, a number of inert gases, and carbon dioxide. It contains a certain amount of light positive and negative ions, ozone.

In order to purify the air in the room, it is advisable to use filters or air purifiers. They can be installed in the ventilation and air conditioning system, if there is one in the room, in this case the air in the entire apartment or in the house will be purified. You can also use portable air purifiers. In this case, we will only clean the air that is in the room where we will install the air purifier. Portable air purifiers are not designed to clean the air in the entire home. Air purifiers can be divided into two groups depending on what they will remove - whether they are purifiers for particulate matter or for gases.

In order to purify the air from the smallest particulate matter, there are two types of filters - mechanical and so-called electronic filters.

To remove air pollution, other harmful gases as well as provide corrosion control, the solution is Gas Phase Filtration Systems https://www.alfaintek.com/products/chemical-air-filters-for-gas-phase.html.

How to clean and recirculate the air in Sick Building Syndrome buildings

According to experts, in the United States alone, between 20 and 30% of buildings are affected by Sick Building Syndrome (SBZ).

Recall that the term was first introduced in the United States. They began to talk about SBZ after they began to build buildings with good thermal insulation, non-opening windows and low ventilation levels to save energy and reduce operating costs. A “sick building” can also be a dwelling where people feel bad because of the poor air quality in it.

The fact is that in Sick Buildings ventilation is often absent or insufficient. And if the ventilation in the room is insufficient, then we observe an increase in the level of content of air pollutants in the room. Modern research has showed that the main pollutant in this case is carbon dioxide. Others are mold, building materials, contaminant gases, dust and high humidity.

In 1992–1997, a group of scientists from different countries conducted special studies of air quality in residential and public buildings. As a result, the main risk factors present in modern houses and provoking the syndrome of sick buildings were identified. This list includes products of fuel combustion (including household gas), building materials and high humidity in rooms.

Clean air for the people in the office as well as electronic equipment the industrial controlled environment with data centers and control rooms can be achieved with Corrosive Air Filtration Unit https://www.alfaintek.com/products/corrosive-air-filtration-unit.html.

How can an increased amount of carbon dioxide in a room affect human health?

As a result of recent studies carried out by scientists from different countries, it was found that even a small excess of the level of carbon dioxide in a room can be potentially hazardous to health if a person is in such a room every day for years, months or even weeks.

If you stay in a room for a long time where the level of carbon dioxide is higher than 600-800 ppm, carbon dioxide can affect the body in the following ways:

May cause negative changes in human blood

Normal acidity (pH) of human blood is about 7.4. Our body is tuned to this figure, it is necessary for the normal functioning of all enzyme and biological systems of the body. It is logical to assume that even small constant changes in blood acidity can have a very strong effect on a living being.

What happens when the concentration of carbon dioxide in the air that enters the body increases? The partial pressure of CO2 in our alveoli increases , its solubility in the blood increases and weak carbonic acid is formed (CO2 + H2O = H2CO3), which in turn decays into H + and HCO3-. The blood becomes acidic, which is scientifically called acidosis. The English scientist D.S. Robertson believes that the higher the concentration of CO2 in the air we constantly breathe, the lower the pH of the blood and the more acidic it has. The scientist identifies the following minimal physiological consequences of acidosis:

• overexcitation,            

• rapid heartbeat,            

• moderate increase in pressure.            

While stronger acidosis person becomes sluggish, lethargic, anxious appears. But all this is already happening with the concentrations of carbon dioxide that exist in modern premises with a large number of people. However, when a person goes out into the fresh air for a long time, everything gradually returns to normal. In underground shelters and bunkers there is no such possibility and that’s why carbon dioxide (CO2) air scrubbers are crucial for such spaces https://www.alfaintek.com/products/air-scrubber/underground-shelters-and-bunkers.html.
