LEAF 320i

cado Air Purifier
Room size: ~ 42m²



A flattened structure of a higher plant, typically green and blade-like, that is attached to a stem directly or via a stalk.
Leaves are the main organs of photosynthesis and transpiration.

“leaf.” Oxford Dictionaries. (12 February 2019)

Beauty that breathes.

Through photosynthesis, plants convert the light they absorb into life-giving oxygen and nutrients they then release back out into the world. Just like in photosynthesis, the LEAF delivers nourishing, invigorating air to your space.


The World No.1

What does it mean to be No.1 in air quality?1

For us, being No. 1 means offering the absolute highest level of both air purification technology and aesthetic design?without compromise. Performance, reliability, or style; our products are the best across every standard and we refuse to make sacrifices. Being No. 1 is our bare minimum.

No. 1 in dust collection since the product's inception.

The CADR (Clean Air Delivery Rate) is an international standard for measuring the dust collection performance of air purifiers, established by the Association of Home Appliance Manufacturers (AHAM) in the United States. It represents the amount of clean air supplied by an air purifier each minute.
The cado air purifier has achieved the highest clean air delivery rate (CADR). Since the brand was created in 2012, cado products have continued to be No. 1 in the world.

Neutralizes and removes over 99% of odors and viruses.

cado air purifier reduces formaldehyde emitted by paint, furniture and similar items, as well as methanethiol and ammonia, which carry odor, to practically zero in one hour. At least 99.9% of viruses, molds and bacterias are eliminated in just 20 minutes.

Operation time / 60 minutes 2
  • ホルムアルデヒド除去率(シックハウスの原因)94.9%
  • メチルメルカプタン除去率(生ゴミ臭・焼き肉臭)99.9%
  • アンモニア除去率(トイレ臭・体臭)99.4%

  • 細菌除去率 99.99%
  2. Attained the top world ranking for clean air delivery rate. The cado AP-C700 air purifier is the first product from a Japanese manufacturer that attained the world’s highest clean air delivery rate (CADR), which is a global standard for air purifiers established by the Association of Home Appliance Manufacturers (AHAM) in the United States. (As of October 2012)

□ Verification of air conditions
□ Turning power ON and OFF
□ Changing air volume
□ Changing operating modes
□ Lights ON and OFF
□ Setting, turning ON and OFF of 24-hour timer
□ Verification of filter life

Devices supported by cado sync app (as of October 2018)
iPhone: iOS 8.0 and later versions
Android: OS4.2 and later versions


Air Purification Speed

The key to effective air purification is speed.

Dust, harmful substances and viruses suspended in air cannot be picked up once they fall to the floor, no matter how powerful a vacuum cleaner may be. This is why the “purifying speed” to draw in all such particles before they hit the floor is so important. The diagonal flow fan incorporated in the LEF 320i powerfully sends air drawn in from all sides straight up 360-degrees around the unit. A large amount of air is circulated quickly in the room to achieve a high air cleaning speed.


Self-cleaning filter

Filter performance that can keep up.

Filter performance is also an important factor in achieving high air purifying speeds. The filter is equipped with a self-cleaning function, and the high performance filter filters air in stages.

1. Self-cleaning function for a long-lasting filter.

The filter features activated carbon for absorbing odor, as well as a self cleaning function which decomposes and eliminates them with LED light using the photocatalytic technology. This cycle of operation allows the filter to restore itself and achieve long service life.

  • 1. Absorption
    Harmful substances and odors are absorbed.

  • 2. Decomposition
    Photocatalytic technology that reacts to visible light is used to decompose particles into carbon dioxide and water inside the base unit.

  • 3. Regeneration
    Self-cleaning restores the absorbing performance. A long service life for the filter is thus achieved.

2. A high-performance filter that catches even the smallest particles.

Air is drawn in, then filtered through stages of high performance filters with various functions. The size of particles captured by the filter is 0.09 μm*. PM2.5, with a particle diameter of 2.5 μm, most certainly cannot pass through it and is captured by the filter.

* μm = micrometer: One thousandth of 1 mm.

  1. Pre-filter
  2. HEPA type filter (inhibits proliferation of virus, mold and bacteria)
  3. Photocatalytic activated carbon filter + Special activated carbon filter (absorbs and decomposes harmful substances)


Minimal Design

A special, narrow frame design takes air purifying performance to the limit.

The edges of the top panel on the LEAF 320i are made extremely narrow to increase the amount of discharged air to enhance air circulation efficiency. An intuitive control panel is installed on the edge to incorporate functionality in a minimal design.



LEDs indicate air quality.

Three LED light colors notify invisible air conditions. The LED light is dimmed to suit the brightness of surroundings for peaceful ambiance at bedtime.
