Air filters: this system uses a filter to capture dust or germs. Filters are made of paper or various fibres, with different efficiencies and service lives.

Using the principle of electrostatics or Electrostatic Precipitator (ESP), it works by releasing negative electrical ions into the air. So that the negative ions trap dust in the air. The negative ions will cause those dust particles to fall on the ground and not float into the air.
Air purification using chemicals or Gas-Phase air filters. This type of air purifier focuses on eliminating various odors that are vapors, gases, and volatile substances in particular. Using chemicals that have the ability to absorb pollutants to act as air filters. This system of air purifiers is commonly installed in kitchens. Because it can filter air that has the smell of cooking gas. and smoke from cooking well
Ozone air purifiers or Ozone generators are air purifiers that use the principle of removing carbon dioxide particles, germs, and various substances that are contaminated in the air using the ozone system. But ozone has quite a number of side effects on our bodies. This makes this system of air purifiers not very popular.
Hybrid Air Purifiers Hybrid Filters Hybrid air purifiers are a combination of the strengths of various air purifier systems. Let's mix it together. Resulting in maximum efficiency in air purification. But the combination of various technologies Together, this air purifier system has a relatively high price.

Air purifiers became popular again after severe PM 2.5 pollution affected many parts of Thailand. The article says that not every air purifier can filter PM 2.5, and describes a PM 2.5-capable unit with a HEPA (High Efficiency Particulate Air Filter) element capable of filtering particles as small as 0.3 microns.

5. How should you use an air purifier correctly?
When choosing the right air purifier and meets the needs The first step to starting using an air purifier is to read the user manual to understand the various guidelines for use in order to use it correctly. and is within the terms of the warranty

The air purifier should not be placed under the air conditioner. Because the air force of an air conditioner is stronger than that of an air purifier. If placed in this position, it will cause the air purifier to work too hard. This is because the air conditioner will suck in more dust than the air purifier can handle. Including the suction force of the air conditioner, it will suck in the air that the air purifier releases. Therefore, the air purifier should be placed away from the air conditioner.

Just take it out and use water to wash it thoroughly. 1 once a month is enough.
HEPA air filter (HEPA Filter) is a high efficiency air filter. which can comfortably filter PM 2.5 dust with a very high resolution This filter should not be cleaned with water or liquid because it will deteriorate faster. Changing the HEPA filter should be done every 6 month.
Carbon Filter (Carbon Filter) is a filter for filtering various odors. In the air Changing the carbon filter in normal use should be changed every 6 month and the carbon filter cannot be washed with water.

Air purifiers come in many designs and price ranges. Prices depend on size, purification capability, additional functions and brand. OBM brands manufacture and sell their own products; the source's examples are blank, and it says their standard prices do not differ greatly.

OEM air purifiers are manufactured by an existing factory under another company's brand. They are usually cheaper than OBM products, and some replacement parts may be interchangeable. Such brands may be less widely recognised or mainly known in their domestic market.

For the air-filter type popular when the source article was written, it gives average OBM prices of 3,000–15,000 baht depending on size, brand and functions. It describes OEM prices as approximately 40% lower than OBM prices.
