Filters for Air Pollution, Home Protection

Air pollution is a very serious problem. In cities with highly polluted air, it can wreak havoc. Like in Mexico City, where according to the National Health Organization, this blight causes 1.8 deaths daily. Much of the blame, warns the same WHO, lies with formaldehydes, which are among the worst pollutants. What to do to protect oneself? A good tool is filters for air pollution in the home.

The air filters are a very important mechanism to prevent air pollution inside the home, and also at work. Just like in vehicles and other uses, they are nothing more than a tool capable of removing the contaminating particles present in the air. Normally, they primarily protect against dust, but they are also effective against other unwanted substances. Pollen, mold, or polluting agents.

The idea of filters for air pollution is to prevent the entry of particles -of various sizes- into our living spaces. So that the air remains clean. They are usually installed in ventilation systems and air entry and exit points.

Choosing Filters for Air Pollution

When choosing filters for air pollution in the home, the first step is to determine the size that will be necessary to install. Normally, these filters for ventilation systems, and also for heating and air conditioning, come in different sizes and also a different thickness scale depending on their uses and possibilities.

One recommendation given by manufacturers of air filters in ventilation systems is that they must fit perfectly in the frame. It is more than desirable that there are no gaps or areas where the filter does not reach, as this could lead to the escape of contaminating elements. If there are gaps, it may be important to consider that this filter is not suitable for the system.

Regarding the thickness of the air filters, they can measure between 1 and 4 inches. Normally, in many homes, the thickness is one inch, but before installing the filter, it is important to review the requirements of the ventilation system and purchase one that also fits in thickness.

It is also very important to look at the efficiency of the air filters. It is very important to consult the recommendations of the system used, whether for air conditioning, ventilation, or heating, regarding the recommended efficiency. Normally, each device has a different efficiency requirement. Just like filters for air pollution in the home require a minimum efficiency.

It is not correct to think that the highest efficiency is needed. As the more powerful the filter, the lower the airflow will be. And this, in the long run, can cause problems in the ventilation system by offering more resistance than necessary due to the air filter.

Different Types of Air Filters

• Activated Carbon Filters. For the separation of viruses and molecular particles.
• Electrostatic Filters. Designed to separate soot and tobacco smoke.
• Wet Filters. With a mesh combined with viscous materials, they retain suspended particles.
• Dry Filters. The airflow filtered will be lower than that of wet filters.

• Gravity Separators: For large particles.
• Inertia Force Separators: A centrifugal force is applied.
• Wet Separators: Water is used to prevent the particles from returning to the airflow.
