Currently, major cities in Vietnam are on high alert due to air pollution levels affecting human health. Therefore, air purifiers are considered the 'saviors' of every household. However, to ensure the best effectiveness, proper usage is crucial.
Choosing the Right Capacity of Air Purifier for the Intended Space
Selecting the appropriate capacity of an air purifier according to the area of use is a crucial factor that determines cleaning effectiveness as well as living expenses.
If you are using it for a large space, do not opt for a low-capacity machine as it will not achieve the desired effectiveness nor be able to eradicate bacteria and viruses completely.
Conversely, if the area requiring air filtration is large but the machine operates with low capacity, it will consume more time and energy without achieving high efficiency.
Choosing air purifiers suitable for the area of use not only brings high efficiency but also saves energy because the fan part of these machines is larger, so running at a capacity of around 7W - 10W can achieve the best filtration.

Correctly Positioning the Machine
Incorrect positioning of the air purifier will result in reduced operational efficiency compared to normal. Typically, air purifiers have a structure consisting of 3 air intake doors into the machine, 2 doors on the sides, and 1 door at the bottom. Therefore, you need to place the machine at least 30cm away from objects such as wardrobes, tables, or barriers to avoid obstructing the airflow.
If your family uses air conditioning, you should place the machine directly under the airflow. This will improve air circulation, helping the air purifier to clean quickly and effectively.
When using the machine, it's advisable to keep the room tightly closed as most models operate on the mechanism of emitting negative ions to combine with the chemical radicals of bacteria in the air for neutralization, making it easy to lose these ions.
Function Usage Guide
Modern air purifiers are equipped with advanced technology to eliminate bacteria and mold, providing the ability to clean the air within a certain period, typically 4 – 6 hours, targeting various types of bacteria. Therefore, it's advisable to activate the device during this time to ensure the air remains fresh and beneficial for health.
For rooms with high levels of air pollution due to prolonged inactivity, they tend to harbor numerous bacteria and molds. Hence, it's recommended to use the highest airflow setting to achieve optimal results.

Regularly Clean Air Filters and Membranes
Regularly cleaning air filters and membranes will enhance the efficiency and performance of the device. Air filters are typically installed at the rear of the machine, making it easy to remove manually for cleaning. You can easily use your hand to remove them and then use a vacuum cleaner or a small brush to clean the filters effortlessly.
It's advisable to perform routine maintenance every 1 – 2 months and replace the membranes once every 2 years to ensure the machine operates effectively.
Guide to Using Energy-Efficient Air Purifiers
Most modern air purifiers are equipped with energy-saving features such as Econavi or Inverter functions. Therefore, it's advisable to switch the device to night mode when not in use or during bedtime to save electricity and promote better sleep.
Only utilize the maximum function when air pollution is severe, and avoid continuous usage to prolong the lifespan of the device. Under normal conditions, keep the device operating in AUTO mode.
Above are the complete guidelines for using air purifiers simply and effectively. Hopefully, this article will be helpful to everyone in utilizing air purifiers!
