Indoor air quality solutions


At Daikin, we’re driven by a simple belief: organizations are at their best when their air is at their best. Thanks to our constant innovations Daikin defines the benchmarks for indoor air quality within the industry. We offer our unique air purifying technology in air purifiers to protect air environments in offices, light commercials, and everywhere clean air is important.

Why air purification?

Why air purification?

We spend 90% of our life we spend indoors. Indoor air can be 2 to 5 times more polluted than the air outside.

Air dampness, humidity levels, odors and floating airborne particles… All of these, unnoticeable at first factors, can cause a lot of physical and environmental damage to our lifestyle.

Three steps to decompose harmful substances


Powerful suction

Three-directional suction reliably takes in dust that tends to collect near the floor from: below, left and right. Its design allows it to take in large amounts of air because the air inlet is located apart from the air outlet so that the airflow from the outlet is soft.

Powerful suction


Effective capture of pollutants

The unit’s electrostatic HEPA filter can collect harmful substances efficiently with the power of static electricity.  Therefore it doesn’t clog as easily as a non-charged HEPA filters that capture particles based on the fineness of the mesh.

HEPA filter



Uses Daikin’s Streamer technology to decompose harmful substances caught on the filter by oxidation 5. Effect after nine hours in a space of about 200L.




Mechanism of decomposition by Streamer

Mechanism of decomposition by Streamer:

Streamer, a high-power plasma discharge technology, decomposes harmful substances (including viruses1, bacteria2, pollen3, mould spores4) inside the unit. These substances are either trapped on the HEPA filter or adsorbed to the deodorizing filter element.

  1. Streamer emits high-speed electrons.
  2. The electrons collide and combine with nitrogen and oxygen in the air to form four kinds of decomposing elements with decomposition power.
  3. The decomposing elements provide decomposition power.


Active Plasma Ion flow outside

The Active Plasma Ion generation unit provides further purification to the space, by adding purifying elements to the cleaned air. These could for example assist to deodorize smelling curtains and carpets.

Removes 99.97% of fine particles of 0.3μm*

Electrostatic HEPA filter
High-performance filter to catch fine particles of dust

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.

Unique vertical structure

Reduced sound operation and improved operation thanks to the new, innovative structure.

Filter cleaning without opening the panel

Easy maintenance

> Filter cleaning without opening the panel

Just vacuum with a cleaner. No need to open the panel to clean the filter.


> Easy-to-detach water tank*

The water tank is conveniently placed in a high position for easy detaching. The compact size of the tank makes it easy to replenish water in a sink or a wash basin.


> Equipped with roll-away casters*

Easy to move to clean the floor.


* URURU model

Powerful humidification* with clean water

The humidifying tray is equipped with a silver ion agent and a water wheel system to keep the humidifying filter from being directly soaked in water.

  • Air purification capacity does not drop even during humidification.
  • Removes bacteria from humidification water with Streamer.
  • No large temperature drop during humidification.
  • Equipped with three humidity settings + moist mode.


* URURU model

Water wheel system

Triple detection sensor

Equipped with a high-sensitivity sensor which reacts while differentiating between small particles sized 2.5µm or smaller, and large harmful substances such as dust and pollen.This in combination with the odor sensor that detects odor concentration, allows the unit to remove harmful substances and achieve high deodorization performance.

Breathe clean fresh air

The Streamer Air Purifier protects your home air environment, where clean air is important. With Daikin’s unique Streamer discharge technology, allergens such as mold, mites and pollen are decomposed and removed, along with unpleasant odors.


[1] Testing organization: Kitasato Research Center for Environmental Science; Test result certificate 21_0026 (issued by same organization); Result of experiment: 99.9% removal of A-H1N1 virus after 1 hour.

[2] Testing organization: Japan Food Research Laboratories. Test number: 15044988001-0201. Test method: Attached a test piece inoculated with bacteria liquid on the upstream side of a dust collection filter installed in an air purifier and operated it in a test area of 25 m³. Counted the number of live bacteria after five hours. Test result: Reduced by more than 99% in five hours. Test unit: Tested with MCK55S (Japanese model), a model equivalent to MCK55W series (turbo operation).

[3] Various allergens were irradiated by streamer discharge and the breakdown of protein in the allergens was verified using the ELISA method, cataphoresis, or an electron microscope (Joint research with Wakayama Medical University). Test example: ‘Japanese cedar pollen Cryj-1’; Test result: 99,6% or more decomposed and removed in 2 hours.

[4] Testing organization: Japan Food Research Laboratories. Test number: 204041635-001. Test result: 99.9% or more of mould (Cladosporium) spores decomposed and removed in 24 hours.

[5] (Reduction of gases) Testing organization: Life Science Research Laboratory.
Test method: After operating a gasoline engine for 10 minutes (when particulate concentration reached 60mg/m3), operated the air purifier for 80 minutes to absorb polluting dust emitted from the engine.
Operated this air purifier for 24 hours in a closed space of 200L and measured the effect to decompose gases.
Test result: Compared with a test without Streamer irradiation, gas components were reduced by 63% in 9 hours.
Test number: LSRL-83023-702.
Test unit: Tested with MCK70N (Japanese model).
