Going into details, it is easy to see the product is quite beautiful. The surface and edges of the plastic parts are carefully crafted, sharp and quality. Hitachi EP-A5000 is manufactured in Japan and imported in complete units for sale in Vietnam market.

The front of the machine is equipped with a table showing the modes and functions of the machine. The process of using the product is done completely through the infrared remote controller included. This is a control with a very simple design, only 6 buttons and made from plastic looking thick and sturdy.

Inside the control panel are 3 filters, which are considered the most important parts of Hitachi EP-A5000. These include:

1. Plastic external filter, can be removed for washing
2. EPA Filter: A 2-in-1 filter including anti-allergenic dust filter and activated carbon filter for deodorizing, can be used for 2 years to replace
3. And moisture filter

In addition to filters, it also has a sensor that detects dust, moisture and odor levels to automatically adjust the air purification, humidifying and deodorizing functions.

Hitachi EP-A5000 has 5 operating modes:

1. Air filter
2. Eliminate pollen
3. Strong deodorant
4. Moisturises and moisturizes skin

For each mode, you can choose the fan speed at automatic level including: Low, medium, strong and maximum (max). It also has Eco mode, which saves up to 23% of power consumption, the device can stop the blower for 50 minutes after 10 minutes of operation in clean room air condition.

With a humidifying function, the machine can disperse moisture up to 520ml of water per hour in maximum operating mode. The water source for humidification and air purification is taken from a 2.5-liter water tank located on the side of the machine. This water pitcher is also very easy to remove when adding water. The manufacturer recommends using clean water and not pouring too cold water into the bottle.

II. Practical experience of air filtering, humidifying and deodorizing capabilities of the machine

Hitachi EP-A5000 does not cause much trouble for users because the operation is quite simple without much support or manuals included. All operations will be done with the remote control, with clear, intuitive buttons.

In automatic mode, the machine works quite smoothly, even when operating with air filtering or humidifying functions, you will not hear noises. Auto mode is also considered to be the mode recommended by the manufacturer to use to ensure the filtering effect and at the same time bring a pleasant feeling.

Moreover, when running in automatic mode, the machine also consumes very low power. According to Quantrimang's test, it only consumes about 3 electric numbers if it runs continuously for 1 month in automatic mode. Of course, in case of deodorizing or quick humidification, the machine will produce more noise and power consumption, but only in a short time, every few minutes to ten minutes.

To evaluate the effectiveness of Hitachi EP-A5000, we use a number of specialized equipment such as electronic hygrometer, noise meter and power consumption measuring device. However, not all functions of this device can be measured using machines but need to use the experience of the experience.

1. Air filtering ability

With this function, you need to pay attention to not cause misunderstandings. Current air purifiers do not have the function of vacuuming like regular vacuum cleaners.

In fact, Hitachi EP-A5000 and air purifiers in general are mainly used to filter dust particles suspended in the air. This series of dust particles is the most harmful to human health and is also the type of dust used to assess the air pollution index of cities today.

Hitachi EP-A5000 has an air purification effect in the following modes:

1. Maximum mode: 5m3 / minute
2. High mode: 4,3m3 / minute
3. Medium mode: 3m3 / minute
4. Low mode: 1m3 / minute

In addition to fine dust filtering, the machine also achieves the certification of Allergy UK (UK) in the ability to reduce pollen and filter mold .

2. Deodorizing ability

To evaluate the effectiveness of this function, we recreated the smell of a normal kitchen space with the smell of alcohol, soy sauce, coffee, carbonated soft drinks, chili sauce and pickles in an enclosed room with an area of about 25m.

When switching to deodorizing mode, the sensor of Hitachi EP-A5000 immediately activates the highest fan level to accelerate deodorizing speed. After nearly 2 minutes of operation at a high and quite noisy fan speed, the machine switches to automatic mode. The unpleasant odors in the room were effectively removed, almost no smell.

3. Moisture generation ability

Use an electronic hygrometer to measure changes in humidity in a 25m2 closed room. Similar to deodorizing function, the moisture-generating effect of Hitachi EP-A5000 is also very clear and fast.

Before turning on the machine, the humidity in the room was 55% and after about 10 minutes of operation at a high fan level, the humidity in the room increased by 60% and remained at that level throughout the process of the humidification regime. dynamic.

You should also understand that Hitachi EP-A5000 creates a different moisture from a nebulizer.

Humidifier is controlled, will automatically disconnect when reaching the appropriate moisture level (usually at 60%), so it can run continuously without worrying about high humidity which affects health as well as electrical appliances in the house. Meanwhile, the nebulizer does not have a self-disconnecting mechanism, the user must feel the humidity in the room to turn off the machine. In addition, the humidification area of ​​the air purifier will also be wider, because the air convection machine is circulating in a continuous, continuous manner and the moisture-bearing air is released regularly, more covered by the blower system.

4. Noise and electricity consumption

The noise and power consumption of Hitachi EP-A5000 are increased according to the level of blowing of the fan. Auto mode and Eco are the two quietest modes and consume the least power.

About noise level:

According to the parameters on the packaging, the noise level in the air purification mode and the air-purifying mode are both equivalent:

1. 50dB at maximum blower level
2. 46dB at a high level
3. 15dB low or automatic

In actual use, most of the time, the device will run in automatic mode and in this mode, the machine emits extremely small noise, not enough to hear even when standing next to it. However, sometimes you will need to increase the level of the fan up to create moisture or quickly deodorize the room.

When the fan is running at level 2, the noise level of Hitachi EP-A5000 has increased significantly and heard clearly but not enough to cause discomfort when near. When the fan is operated at level 3 and the maximum level (max), the noise level increases enough to wake the sleep if lying near the machine.

However, you can rest assured that the high fan mode normally only works for a few minutes when it is necessary to quickly moisten or deodorize that the machine will automatically switch to a low level, causing no noise.

About electricity consumption:

Similarly, the noise and electricity consumption also depend on the speed of the fan, which ranges from 4W to 15W and the highest is 50W.

In fact, when running in automatic mode, the machine consumes about 0.12 electricity per day, equivalent to more than 3 numbers per month.

When operating at a moderate (level 2) or high (fan 3 and Max) level, the power consumption increases several times to dozens of times the automatic mode.

However, as mentioned above, the time of high fan operation is usually very short, only a few minutes so there is no need to worry about power consumption when using Hitachi EP-A5000.

III. Overview review

Overall, the Hitachi EP-A5000 is a humidifier and humidifier with a compact, eye-catching design. The operation is also easy to use, simple. The machine has many modes of air purification, humidification can be adjusted flexibly according to user needs.

The effect of dehumidification and deodorizing can be seen very clearly during use. The device makes almost no noise and also consumes very little power when used in normal daily mode (automatic mode). Therefore, users can comfortably and peacefully let the Hitachi EP-A5000 work around the clock to filter the air, create moisture and limit bacteria, mold, etc. in the home.

However, this product also has a few points to keep in mind: the price is quite high because direct import from Japan and EPA filter may need replacement after 2 years of use or may be longer if the level of pollution is low. . If you overcome these limitations, then the device will be an extremely ideal suggestion for your family.
