air purification

Pure air, because we care

With Daikin air purifiers, we promise you air that is cleaner, healthier and fresher.

Daikin’s unique double method

1. The Streamer unit, a high power plasma discharge technology, decomposes harmful substances* inside the unit. These substances are either trapped on the HEPA filter or adsorbed to the deodorizing filter element.

* Substances including: viruses1, bacteria2, pollen3, mould spores4


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.


2. 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.


Plasma discharge emits high-speed electrons.


The electrons collide and combine with nitrogen and oxygen in the air to form four kinds of elements.


These elements provide decomposition power.

Mother And Daughter Reading In Healthy Room

Breathe in air that is clean and healthy

Daikin air purifiers minimise asthma and allergy symptoms by removing dust particles and pollen from your air, and keep you healthy by filtering airborne bacteria and viruses.

Clean Room With Controlled Humidity

Humidity is essential for healthy skin

The humidifying air purifier's slim water tank infuses moisture into the air when it is too dry, and keeps you from fighting dry hands or waking up with a scratchy throat.

Three steps to decompose harmful substances

1 Powerful suction

Takes in air over a wide area from 3 directions.

2 Effective capturing of pollutants

Efficiently catches dust and pollutants with an electrostatic HEPA filter.

3 Decomposition

Uses Daikin's Streamer technology to decompose, by oxidation, harmful substances caught on the filter.*


Indoor Air Quality, A Daikin Experience

The Streamer Symbol consists of three C’s

CLASH: The dust collection filter catches the floating substances with the attached harmful gases and Streamer decomposes
the gases by oxidation.

CYCLE: The deodorising filter adsorbs and decomposes odour. Thanks to the regeneration of the adsorbing capacity, the deodorising capacity is maintained. No need to change the deodorising filter , unlike air purifiers with activated carbon filters.

CLEAN: Removes bacteria from dust collection filter and humidifying filter.


High performance HEPA filter to catch fine particles of dust


Removes 99% of particles between 0.1μm and 2.5μm in size

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

Therefore, a larger amount of air can pass through the filter and can purify a larger amount of air than other technologies.

Electrostatic HEPA filter vs Non-electrostatic filter


Electrostatically charged

  • Removes 99,97% of fine particles of 0,3μm
  • Filter fiber itself is charged with static electricity, and collects particles efficiently
  • Doesn’t clog easily, hence less pressure loss

Electrostatically neutral

  • Because it catches particles relying only on mesh size, it is necessary to make mesh finer, making it easy to be clogged and cause high pressure loss

It may become necessary to change out items that usually do not require replacing due to environmental and operational conditions.
