Easy Maintenance & Cleaning

Auto Self Clean ­ Auto Filter Cleaning Robot
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.

Auto Self Clean Unit
*1 Testing 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).

Easy maintenance

**As a rule, empty the dust box about once a year**
When the dust box becomes full of dust, an indication4 lets you know it is time to empty it. The box needs to be emptied about once a year, so it is not troublesome.
3 Based on the results of dust accumulation tests (assuming collection of approx. 0.2g of dust/month in an approx. 20m room. In-house investigation.) The amount of dust differs depending on the environment in which the unit is used. Please regularly check the dust box and empty it when necessary.
4 The 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.

Easy Maintenance & Hygienic

Stainless Clean System

Stainless steel anti-bacterial effect keeps it hygienic. The stainless steel used in the pre-filter, flap and net outlet help eliminate bacteria.

*1 Not 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)

Deodorising

**Washable deodorising filter Replacement not necessary for approx. 10 years***

Filter can be washed with water to restore deodorising power* . This helps to reduce four major types of odour bases: nitrogen, aldehyde, acid and sulphur components.

How deodorising power is restored

1 In accordance with the JEM1467 standard of the Japan Electrical Manufacturers’ Association. The number of years after which the odour elimination rate decreased by half with 5 cigarettes smoked per day. Maintenance or replacement may be required depending on conditions of use and the type and strength of odours.
2 Depending on the odour, washing with water may not eliminate it. Restoration of deodorising performance by washing with water gradually declines.

Results of odour elimination tests in a 25m test space using single odor components. Odour elimination performance differs under conditions of actual use in a room. Tests performed by Hitachi.

Sulfur-based
Hydrogen sulfide (Odours from drain outlet and toilets) Methyl mercaptan (Odours from rotten vegetables)
Results of deodorising performance tests performed in a 1m3 test space with single odour components. Deodorising performance differs depending on the space where the unit is actually used. Testing authority: Japan Food Research Laboratories

Dust Collection Performance

Allergen-free HEPA for fine dust

Effectively captures fine particles
The multi-layered structure of Allergen-Free HEPA Filter for fine dust effectively catches fine particles including dust, cedar pollen and airborne mould. It also suppresses the PM2.5.

HEPA Filter collects 99.97% or more dust containing fine particles of 0.3m 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 filter
• Test 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

*Air Purifier suppresses airborne viruses and bacteria³*
This is the effect on airborne viruses and bacteria after 13 minutes in a 25m3 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). 3 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 25m3 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 airflow).

Example of particle sizes (Surveyed by Hitachi)

Wide and speedy dust collection
Applicable to a 79m² floor space. Rapidly collects dust in just 6 minutes in a 13m² room.
Increased air intake surface area achieved on the back lateral sides. By widely collecting dust from both sides, a 13m room can be quickly purified in a mere 6 minutes.

Time taken to clean
Displays time taken for dirt (powdered dust) of standard thickness to reach a level lower than the standard amount of such powdered dust in a room of approx. 13m2.
Speedy air purifying with a massive air volume of 11m3 per min.
Wide range air intake
Mechanism for wide & speedy dust collection
PM2.5 sensor detects fine particles, cleans them up with max air flow

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 particles2 of 0.1m and larger (0.5m or larger with the dust sensor detection). Continues super-sensitive patrol operation even after cleaning the air.

*1 Comparison with normal automatic air purification mode. Time required for reducing an initial concentration of approx. 1,000 g/m to 35 g/m . Normal automatic air purification mode: 38 min, PM2.5 sensing automatic operation mode: 20 min. Surveyed by Hitachi.

*2 Cigarette smoke.

*99% of 0.1 to 2.5m particles caught³ — 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 2.5m or less in diameter. Removal of particulate matter less than 0.1m has not been verified. Further, not all harmful substances in the air can be removed. Results were obtained in a sealed 32m3 space and not in an actual living space.

Low operating sound and energy-saving

Special emphasis has been placed on reducing noise during operation and lowering electricity cost
Low noise operation
*Operation cuts energy consumption by up to 14% compared to normal automatic operation*
When the air is clean or the level of humidity is suitable, the fan automatically pauses and resumes operation every hour.
1 Energy consumption compared between automatic operation and ECO operation in air purifying mode. Automatic operation: 6.8Wh, ECO operation: 5.6Wh. Tested by Hitachi. Reduction rate of power consumption varies depending on how dirty the air is. Reaction toward dealing with dirty air and corresponding to humidity changes may be slower compared to normal operation mode.

EP-L110E
Auto Self Clean makes maintenance easy. And air drawn in from a wide area enables the collection of dust in a 13m room in just 6 minutes.

Hitachi’s Air Purifiers were awarded the Allergy UK Seal of Approval in recognition of their proven ability to reduce exposure to allergens.
