Fine dust is always present in the air, so when we breathe, we always inhale it. Currently, pollution is increasing day by day, and the proportion of fine dust in the air is also increasing, significantly affecting human health. The solution proposed is to use air purifiers. However, can air purifiers filter fine dust? Let’s explore the answer in this article.
1. Understanding fine dust and its impact on health
1.1. What is fine dust?
Fine dust is often represented by the abbreviation “PM2.5” (Particulate Matter 2.5), which are very small particles present in the air. Their size is less than 2.5 micrometers – smaller than the diameter of a human hair. These particles are present in the air that we breathe daily, not only outdoors but also indoors.
1.2. Impact of fine dust on human health
Respiratory and allergic issues: Fine dust particles can penetrate deeply into the respiratory system, especially the lungs. This can cause respiratory problems such as bronchitis, pneumonia, and increase the risk for people with asthma or chronic lung disease. Inhaling a large amount of fine dust particles can cause itching, sore throat, and difficulty breathing.
Cardiovascular system risk: Studies have shown that fine dust particles can also affect the cardiovascular system. They can enter the circulatory system, causing inflammation and hindering blood circulation. This can create a favorable environment for cardiovascular issues such as hypertension and stroke.
Long-term health effects: Continuous exposure to fine dust particles can lead to long-term health effects. The risk of lung cancer, chronic lung disease increases, and can even affect the digestive and immune systems.
2. Can air purifiers filter fine dust?
The answer is Yes. Although fine dust particles are extremely small and difficult to see with the naked eye, they can be filtered out thanks to the operation mechanism of air purifiers.
One of the commonly used filters in air purifiers is the HEPA filter. HEPA filters are designed to trap very small particles with high efficiency, cleaning fine dust particles up to 99.97%. Particles with a diameter of 0.3 micrometers – a size that is not visible to the naked eye – can be cleaned by the machine.
3. Factors affecting the performance of air purifiers
The performance of air purifiers depends not only on the type of filter used but also on a range of other factors. Below are some important factors affecting the ability of air purifiers to remove fine dust and improve air quality:
3.1. Capacity and filtration ability of the machine
The capacity and filtration ability of air purifiers determine the level of air processing within a specific period of time. Machines with higher capacity often have better filtration capabilities, especially in large spaces. A machine with a faster air processing rate will help maintain good filtration when there are many fine dust particles present.
3.2. Type of filter
Your choice of filter type also significantly affects performance. HEPA (High-Efficiency Particulate Air) filters are often a good choice because they can remove fine dust particles with high efficiency. Additionally, activated carbon filters can help remove unwanted odors and other particles.
3.3. Room size and efficiency level
The room size affects the efficiency of air purifiers. A purifier with the ability to handle air volume suitable for the room size will ensure that the air in the room is filtered and improved.
3.4 Filtration speed
Filtration speed affects the ability to remove fine dust particles and other particles in the air. A faster filtration speed often results in better performance, but it is important to note that higher filtration speeds may also produce more noise.
3.5. Regular filter replacement
Regularly replacing filters according to the manufacturer’s instructions is important to maintain the best performance of the air purifier. Dirty filters can reduce efficiency, and the air may not be properly filtered.
