An air purifier: What is it? The functions of an air purifier

In today’s era, air quality has become one of the top priorities for our health and comfort. With the increasing air pollution from various sources such as dust, industrial emissions, and vehicles, finding effective solutions to clean the air has become more important than ever. In this context, air purifiers have become an essential tool to help us maintain clean and healthy living and working environments. So what is an air purifier? What are its functions? Let’s explore through the following article together with Puritrak!

1. What is an air purifier?

An air purifier is a device designed to remove dust particles, bacteria, harmful microorganisms, air pollutants, odors, and other toxic substances from the air in a specific space such as indoors, offices, or industrial spaces. The main function of an air purifier is to improve the quality of the air we breathe, help clean the air, and create a healthier living and working environment.

2. The main functions of an air purifier

2.1. Efficient air filtration, odor removal, and bacteria elimination

Modern air purifiers are often equipped with 4 to 5 layers of different filter membranes, including HEPA filters, designed to capture ultrafine dust particles as small as 2.5 micrometers, which are usually invisible to the naked eye.

HEPA filters typically adhere to the H13 standard, one of the highest standards for air purifier filters. This standard is regulated by the US Department of Energy (DOE) and the EN 1822:2009 standard of the European Union. Determined by measuring the percentage of 0.3-micrometer dust particles (PM2.5 fine dust) that HEPA filters can capture, the H13 standard typically retains 99.97% of these particles.

2.2. Elimination of mold, allergens, and other allergenic substances

According to research by the Retro Screen Virology Institute (UK) and the Central Institute of Hygiene and Epidemiology (Vietnam), air purifiers using Plasmacluster ion technology have the ability to eliminate up to 99.9% of mold, bacteria, viruses, especially influenza viruses, and allergenic substances.

Plasmacluster ion technology in air purifiers operates based on the principle of emitting electrically charged ions that affect the protein structure of bacteria and viruses, causing them to break down and prevent their proliferation.

2.3. Effective mosquito trapping

Currently, most air purifier models on the market are equipped with unique mosquito trapping features. As a tropical country with abundant rainfall, Vietnam is an ideal environment for mosquitoes to thrive. Using air purifiers can reduce mosquito breeding, protecting your family.

Air purifiers effectively trap mosquitoes by using methods such as UV light, mosquito-attracting dark traps, and suction airflow to attract and capture mosquitoes and small insects inside the machine. This helps reduce the presence of mosquitoes in living spaces and improves overall air quality. However, the effectiveness of mosquito trapping may vary depending on the specific design and features of each type of air purifier.

2.4. Effective static electricity reduction and energy savings

Modern air purifiers are equipped with Inverter technology, significantly saving energy. You can use the machine continuously 24/7 without worrying about electricity bills, as the energy consumption in auto mode is equivalent to that of a regular incandescent bulb indoors, about 30 ~ 50 W/h.

Additionally, air purifiers also support static electricity removal, preventing dirt and pollen from sticking to curtains, clothing, and other surfaces in the room.

2.5. Humidification technology helps moisturize skin and hair

Some air purifiers are supplemented with automatic humidification functions by generating water vapor through humidification filters and naturally evaporating it into the air, helping maintain moisture levels in the room at a stable level.

This natural evaporation humidification system helps prevent dry skin and throat, thereby preventing respiratory diseases.

2.6. Effective removal of cigarette smoke, food odors, and harmful dust smoke

Odors such as cigarette smoke, food odors, and harmful dust smoke often cause discomfort for people and even pose risks of respiratory diseases.

Activated carbon filters in air purifiers can retain various odors and simultaneously release ions into the air, effectively eliminating odors in the room.

With high-end air purifier models equipped with advanced filters, many types of toxic gases, engine exhaust gases, and chemical odors indoors can be effectively removed. You will feel the significant effects in just 10 – 20 minutes.

2.7. Optimizing product experience with additional features

In today’s busy life, household appliances are often equipped with automatic features to help users save time and effort. Current air purifiers on the market are also equipped with some automatic features that you can choose from:

Timer shutdown: This is one of the features that helps save energy for families when users accidentally forget to turn off the device when not in use.

Filter replacement alert: This helps homeowners easily grasp the time to replace or maintain the filter regularly, thereby increasing the lifespan of the product.

Auto start when electricity is available: This feature supports automatically reconnecting the program after the machine is suddenly powered off.

Fan level indicator light: Helps users easily monitor the level of fan speed in use to adjust to the appropriate needs.

Air quality sensor in the room: Helps homeowners monitor the air quality in the room, indoors for timely air treatment.

WiFi connection allows users to remotely control: Supports remote control, allowing users to operate without direct manipulation when needed.

These features will make your use of the machine more convenient and control its operation better than ever through smartphones.

Thus, an air purifier is not just a simple device but also an indispensable part of our modern life. By removing pollutants and creating a clean and healthy air environment, they help protect our health.
