Hitachi’s Air Purifiers were awarded the Allergy UK Seal of Approval in recognition of their proven ability to reduce exposure to allergens.
- Tested by Allergy UK (The British Allergy Foundation).
- Tested with house dust mites and pollen.
Auto Self Clean
When the Auto Self Clean unit operates, it moves up and down while brushing the pre-filter to remove dust, which is then collected in the dust box.
Pre-filter Comparison After 1 Month of Operation*2
Easy Maintenance
When the dust box becomes full of dust, an indication*3 lets you know it is time to empty it. The box needs to be emptied about once a year, so it is not troublesome.
*1Testing authority: Boken Quality Evaluation Institute. Test methods: JIS Z 2801 antimicrobial test (film adhesion test). Target: adhesive bacteria. Antibacterial method: antibacterial components in resin. Test results: antibacterial activity value of 2.0 or higher (An antibacterial activity value of 2.0 or higher indicates an antibacterial effect).
*2Based on test results using the Auto Operation mode in an approx. 30㎡ living room.
*3The indication is a rough guide. Even when the pre-filter is automatically cleaned, depending on conditions of use and the environment, there may be dirt that cannot be removed from the filter. If you are concerned about greasy dirt or other kinds of stubborn dirt, please regularly remove the filter and clean it.

*1Not all of the bacteria in the air released by the air purifier are eliminated. Antibacterial effect of the (1) stainless pre-filter, (2) stainless flap, and (3) stainless net (outlet)
Testing authority: (1) and (2) Boken Quality Evaluation Institute, (3) Kitasato Research Center for Environmental ScienceTest method: JIS Z 2801 (film contact method) Test item: Attached bacteria Sterilization method: Using the metal ion contained in stainless steel Test results: 99% of bacteria eliminated after 24 hours.
*2Stainless-steel coating.
*3There is no anti-bacterial effect in the air released by the air purifier. Anti-bacterial effect of the silver ion fan
Testing authority: Boken Quality Evaluation Institute Test method: JIS Z 2801 (film contact method) Test item: Attached bacteria Anti-bacterial method: Anti-bacterial components included into the silver ion fan Test results: Anti-bacterial activity value 5.1 (anti-bacterial effect is present when the activity value is more than 2.0).
Deodorizing Filter
Filter can be washed with water to restore deodorizing power*. This helps to reduce four major types of odor bases: nitrogen, aldehyde, acid and Sulfur components.
How Deodorizing Power is Restored
Nitrogen-Based
Aldehyde-Based
Acid-Based
Sulfur-Based
Results of odor elimination tests in a 25㎥ test space using single odor components. Odor elimination performance differs under conditions of actual use in a room. Tests performed by Hitachi.
Results of deodorizing performance tests performed in a 1㎥ test space with single odor components. Deodorizing performance differs depending on the space where the unit is actually used. Testing authority: Japan Food Research Laboratories.
*Depending on the odor, washing with water may not eliminate it. Restoration of deodorizing performance by washing with water gradually declines.
Allergen-Free HEPA Filter
Effectively Captures Fine Particles
Multi-layered structure of Allergen-Free HEPA Filter for fine dust effectively catches fine particles including dust, cedar pollen and airborne mold. It also suppresses the PM2.5.
HEPA Filter Collects99.97%
or more dust containing fine particles of 0.3µm at a rated air flow
Based on performance of a single HEPA filter complying with the JIS Z 8122. Overall room dust removal performance may differ.
Suppresses Activity of Captured Allergen Substances
The allergen-free components of the HEPA Filter for fine dust suppress the activity of cedar, birch & ragweed pollen, dust mite dung & cat dandruff that have been captured.
- Testing authority: Nichinichi Pharmaceutical Co., Ltd Test method: ELISA Suppression method: Application of anti-allergen agent to filterTest results: Cedar pollen 96% suppression, birch pollen 90%, ragweed pollen 96%, American dust mite dung 93%, European dust mite dung 91%, and cat dandruff 85%. Value in percentage calculated by Hitachi.
Example of Particle Sizes (Surveyed by Hitachi)
Air Purifier Suppresses Airborne Viruses and Bacteria*
This is the effect on airborne viruses and bacteria after 13 minutes in a 25㎥ test space, not the proven effect in a space where the filter is actually used. Effects may differ according to conditions and method of use. Tests performed conform to the Japan Electrical Manufacturers’ Association standard (HD-124).
*Virus/ bacteria suppression effect
Testing authority: Kitasato Research Center for Environmental Science Test method: Performance evaluation test conforming to the Japan Electrical Manufacturers’ Association standard (HD-124) conducted in a 25㎥ test space. Same test applied for bacterial suppression effect Test item: 1 type of airborne virus/1 type of airborne bacterium Test results: 99% or more suppressed in 13min Model used: EP-L110E (with max air flow).
Wide and Speedy Dust Collection
Increased air intake surface area achieved on the back lateral sides. By widely collecting dust from both sides, a 13㎡ room can be quickly purified.
PM2.5 Sensor
Purifies PM2.5 Particles with a Massive Air Volume – Much Quicker than The Normal Automatic Air Purification Mode
Switches to high-sensitive detection mode and purifies fine dust with max air flow operation.*1 HEPA filters enable the collection of fine particles*2 of 0.1µm and larger (0.5µm or larger with the dust sensor detection). Continues super-sensitive patrol operation even after cleaning the air.
99% of 0.1 to 2.5µm Particles Caught*3
— Ready to Remove PM2.5 Particles
New particles entering from outside during ventilation or by other means are not considered here.
PM2.5 is a collective term for particulate matter of 2.5µm or less in diameter. Removal of particulate matter less than 0.1µm has not been verified. Further, not all harmful substances in the air can be removed. Results were obtained in a sealed 32㎥ space and not in an actual living space.
Comparison of Purification Time
*1Comparison with normal automatic air purification mode. Time required for reducing an initial concentration of approx. 1,000µg/㎥ to 35µg/㎥. Normal automatic air purification mode: 38min, PM2.5 sensing automatic operation mode: 20min. Surveyed by Hitachi.
*2Cigarette smoke.
*3Odor sensor does not activate during the PM2.5 sensing mode.
Humidifying
Two selectable modes provide the desired level of humidity.
Humidifying Mode
This humidifies clean air to increase the humidity in a room to about 50%. And it can be used in combination with the deodorizing course.
Skin Moisturizing Mode
Room humidity can be increased up to about 60%*. This helps keep your skin moist in the dry season and when using air conditioning.
*Humidifying capability may change due to temperature, humidity and other conditions.
- The effect differs between individuals. It also differs depending on the season, room temperature and other conditions.
