Air purifiers are popular home appliances that function by filtering indoor air to remove pollutants and odors, providing a fresher, healthier indoor environment. So, how do air purifiers work? Does it really help remove odor? Let’s take a closer look.
The working principle of an air purifier can basically be divided into three main steps: suction, filtration and release.
The first step is to breathe in air. Air purifiers usually come with a fan that draws air into the room. The process works similarly to a regular fan, but with a special filtration system that captures tiny particles in the air.
The next step is filtering. When air is sucked in, it passes through one or more filter layers. These filter layers use different types of filter materials, such as mechanical filters, activated carbon filters, and HEPA (high-efficiency particulate air) filters, to capture and remove different types of pollutants.
Mechanical filter is one of the most basic filter layers, consisting of a fine fiber mesh. It effectively captures large airborne particles such as dust, pollen and pet dander. Activated carbon filters are designed to remove odors and volatile organic compounds (VOCs). Activated carbon has a porous structure that can absorb and neutralize odor molecules in the air.
One of the most important filtration layers is the HEPA filter. HEPA filters use a dense fiber mesh that effectively captures tiny particles in the air, including bacteria, viruses, mold, dust mites, and smoke particles. This makes HEPA filters one of the most commonly used air purifier filtration technologies.
The final step is to release the purified air. After filtering, the air purifier releases clean, purified air back to the indoor environment. This way, you can enjoy fresher, healthier indoor air.
So, do air purifiers really help get rid of odors? The answer is yes. By using activated carbon filters, air purifiers can effectively absorb and neutralize odor molecules in the air, such as tobacco smoke, kitchen fumes, and pet odors. At the same time, by removing pollutants and particulate matter, air purifiers can significantly improve air quality and reduce odors in the air.
In addition to removing odors, air purifiers have many other benefits. They can remove allergens from the air and reduce allergic symptoms; reduce the number of bacteria and viruses in indoor air and improve indoor hygiene; reduce dust and particles in indoor air and protect your respiratory health, etc.
To sum up, air purifiers effectively remove pollutants and odors from the air through the process of inhalation, filtration and release, providing a fresher and healthier indoor environment. Whether it's to improve air quality, reduce allergy symptoms, or remove odors, an air purifier is a home appliance worth considering. Now, choose the leking air purifier that suits you and enjoy fresh and healthy indoor air!
