Air Purifiers

Number one choice for crystal clean air at home.

Daikin offers its unique air purifying technology in air purifiers to protect air environments in the home, office, and everywhere clean air is important.

Daikin air purifiers are high-quality air filtration systems designed to help improve indoor air quality.  Equipped with advanced filters that captures a wide range of airborne pollutants and allergens, including dust, pollen, pet dander, smoke, and even bacteria and viruses.

Daikin air purifiers use a multi-stage filtration process that typically includes a pre-filter to capture larger particles, a HEPA filter to capture smaller particles, and an activated carbon filter to remove odors and harmful gases. It also comes with features like air quality sensors, automatic operation, and energy-saving modes, which make them very convenient and easy to use.

Electrostatic HEPA Filter

Removes 99.97% fine particles of dust ( 0.3μm) using electrostatic power


The filter collects dust efficiently with electrostatic forces. It is not prone to clogging compared with unelectrified HEPA filters (which collect particles only by the fineness of the mesh)


Larger amount of air can pass through the filter.


The filter can purify a larger amount of air!

Levels of Air Purification

1) Pre-Filter – acts as an initial defense mechanism, capturing larger particles and helping to protect and prolong the lifespan of the inner filters, this ultimately improves the overall air purification process.

The pre-filter is an important component and is the first line of defense in the filtration process and plays a crucial role in capturing larger particles before they reach the inner filters. Its primary function is to trap larger particles such as dust, pet hair, lint, and other visible contaminants. It acts as a physical barrier, preventing these larger particles from clogging or damaging the more sensitive and specialized filters that come after it.

By capturing larger particles, the pre-filter helps to extend the lifespan and maintain the efficiency of the subsequent filters, such as the True HEPA filter, activated carbon filter, and other advanced filtration stages. This means that the inner filters can focus on capturing smaller particles, such as allergens, mold spores, bacteria, and volatile organic compounds (VOCs), without being overwhelmed by larger debris.

2) Deodorizing Filter – Plays a crucial role in eliminating odors and reducing the presence of harmful gases.

The deodorizing filter, also known as the activated carbon filter, is commonly found in Daikin Air Purifiers. Its primary function is to remove odors and harmful gases from the air.

When air passes through the deodorizing filter, the activated carbon absorbs and holds onto odor-causing molecules and chemical compounds. This helps to neutralize unpleasant smells from sources such as smoke, cooking odors, pet odors, and household chemicals. In addition, the activated carbon filter can also help reduce the concentration of harmful gases and chemicals in the air, including formaldehyde, benzene, toluene, and other volatile compounds that may be released from household products or indoor pollutants.

3) Dust Collection Filter or Electrostatic HEPA Filter – provides improved filtration efficiency and enhances the ability of the air purifier to remove smaller particles from the air, contributing to cleaner and healthier indoor air quality.

An electrostatic HEPA (High-Efficiency Particulate Air) filter is a type of filter used in Daikin air purifiers to enhance the filtration efficiency and capture even smaller particles from the air. It combines the benefits of both electrostatic and HEPA filtration technologies. It’s known for their high efficiency in capturing particles as small as 0.3 microns with an effectiveness of 99.97% or higher. They work by using a dense fiber matrix that mechanically traps particles as air passes through the filter.

An electrostatic filter, on the other hand, uses an electric charge to attract and trap particles. It relies on the principle of static electricity to create an electrostatic field that attracts particles with an opposite charge. This electrostatic attraction enhances the filtration efficiency, allowing the filter to capture smaller particles that may have otherwise passed through a standard HEPA filter.

4) Active Plasma Ion (API) is a technology utilized in certain air purifier models offered by Daikin. It is designed to further enhance the purification capabilities of the unit by generating and releasing ions into the air.

It provides an additional layer of purification by releasing active plasma ions into the air that helps neutralize airborne particles, including bacteria, viruses, mold spores, allergens, odors, and VOCs, contributing to cleaner and healthier indoor air.

Active Plasma Ion technology works by creating a high voltage discharge that energizes and converts oxygen molecules (O2) into active plasma ions (O2+). These ions are then released into the air where they interact with various airborne particles and pollutants which have several beneficial effects on the air purification process. They can neutralize and eliminate harmful substances, including bacteria, viruses, mold spores, and allergens. The ions can disrupt the protein structures and cell membranes of these particles, rendering them inactive or incapable of reproducing.

Additionally, these help to neutralize odors and volatile organic compounds (VOCs) by breaking down their chemical compounds. This can result in fresher and cleaner-smelling air.

5) Streamer technology is a technology patented by Daikin, designed to enhance the air purification process by generating high-speed electrons that forms four kinds of decomposing elements which effectively breaks down and eliminates bacteria and viruses captured in the filter.
Streamer technology is the air purification technology patented by Daikin. This works by producing high-energy electrons using a discharge unit. The electrons then collide with oxygen and moisture in the air, resulting in the generation of highly reactive components known as plasma discharge, or “streamers.“

These streamers are rich in reactive species such as hydroxyl radicals, hydrogen peroxide, and superoxide ions, which possess strong oxidative properties. When released into the air, these reactive components actively break down and decompose harmful substances like allergens, bacteria, viruses, mold, and volatile organic compounds (VOCs).

6) A humidifying filter is responsible for adding moisture to the air by absorbing water from water tank and releasing it into the surrounding environment.

The humidifying filter is consist of an absorbent material, such as a paper or fabric wick, that has a large surface area. This material absorbs water from the humidifier’s reservoir through capillary action. As the air passes over the moistened filter, it picks up moisture, increasing the humidity in the room.

The main purpose of a humidifying filter is to improve indoor air quality by increasing humidity levels, particularly in dry environments. Dry air can cause various issues, including dry skin, irritated respiratory passages, static electricity buildup, and even damage to wooden furniture or musical instruments.
