Panasonic's new air purifier F-655FCV is available first

Since last year, the air purifier industry has shown an explosive trend, with various brands and models emerging one after another, making people confused. For consumers, if they want to buy a reliable product in the mixed air purifier market, the easiest and most feasible way is to choose a regular product from a well-known brand.

As a giant in the Japanese home appliance industry, Panasonic naturally has a complete product line of household appliances. Air purifiers are also a type of household appliance that Panasonic focuses on promoting in China. The F-655FCV reviewed this time is the latest air purifier that Panasonic will launch in China.

● Overview

Strictly speaking, the F-655FCV is a multi-purpose purifier that combines passive adsorption filtration + active sterilization technology; in addition, it is also equipped with Panasonic's ECO NAVI energy-saving navigation technology, as well as additional gasification humidification technology. It has a certain environmental perception and automatic operation capability, and is more suitable for use in dry northern regions.

Compared with conventional purifiers, the "nanoe nano water ion" technology of the F-655FCV is an exclusive selling point. The charged nano water particles are generated by applying high voltage to separate water molecules in the air, achieving additional purification and even disinfection effects.

The effects of nanoe nano water ions are mainly reflected in the following five aspects:

1. High water content. The water content of nanoe nano water ions is 1000 times that of general negative ions. It is naturally formed by the dew reaction of water in the air. It can be said to be a veritable "water" ion. Therefore, nanoe nano water ions are very effective in moisturizing.

2. Nano-level particle size. Nanoe nano water ion particles are very small, only 5-20nm, reaching the nano level, which is 1/1 billion of ordinary water molecules. Therefore, they can thoroughly penetrate into the fine fibers and deep into the stratum corneum, thereby taking effect, surrounding and inhibiting allergic substances such as pollen, lice corpses, feces, etc.

3. Strong stability. Since nanoe nano water ions are wrapped in water, they are not easy to combine with oxygen and nitrogen in the air, and can fully reach and react with various bacteria to neutralize them. At the same time, compared with general negative ions, the stability is up to 6 times, so its effect time is longer and the reach distance can be up to more than 10 meters. Therefore, it can reach every corner of the room.

4. A large amount of OH ions. Nanoe water ions generate 480 billion OH ions per second. OH ions are used to absorb various bacteria in the air and decompose them into healthy water molecules, thereby inhibiting and removing bacteria and viruses.

5. Weak acidity. Nanoe water ions have weak acidity similar to human hair and skin, and are mild and non-irritating.

● Appearance

This new air purifier has an appearance that is completely different from any product that has been launched in the past. If it weren’t for the huge “PANASONIC” trademark on the front, you would never have thought that this is a Panasonic purifier.

Compared with the square purifiers in the past, the F-655FCV has a very complex shape: a black glass panel tilted backwards on the front, a cylindrical white body at the rear, and a transparent base at the bottom. Not only is the shape complex, it also has a more technological feel than previous models.

Due to the change in appearance, the air duct of F-655FCV has also changed. Panasonic's previous purifiers basically adopted the design of front panel air intake + top air outlet, while F-655FCV has changed to rear air intake + top air outlet. This change is obviously a product of compromise to appearance, because Panasonic's previous products have always used the flexibility of front air intake and the multiple air intake modes brought by the sliding front cover as selling points. As to whether this change will lead to performance loss, it will be tested later.

● Panel

The F-655FCV's full glass front panel provides a variety of display prompts, and the visual effect after starting the machine is quite good.

In addition to various status indicators, the F-655FCV can intuitively display the current relative humidity of the air on the panel. The air quality status prompt is mainly indicated by the PM2.5 light strip and the light color of the base, allowing users to understand the changes in air quality very intuitively and conveniently.

● Filter

The filter structure of F-655FCV includes 5 layers, namely the pre-filter, HEPA filter, deodorizing filter, formaldehyde filter and humidifying filter. This is a very mainstream configuration for mid-to-high-end purifiers. The pre-dust collection filter has passed the antibacterial certification, which is exclusive to Panasonic. The HEPA filter can filter particles as small as 0.3 microns, which is an advanced configuration among similar products.

The deodorization and formaldehyde filters are highly similar, and they should be made of the same filter material.

The border colors of the deodorizing filter and the formaldehyde filter are different, but the structure and form of the filter materials are very similar, so they should use filter elements made of the same material.

F-655FCV also provides an impeller-type vaporization humidification device, which is more common in Japanese mid-to-high-end purifiers. Compared with ultrasonic humidification technology, this humidification technology is more comfortable and will not form a white covering on the surface of furniture. It is safe and convenient.

● Power consumption & noise

A purifier is a machine that needs to keep working for a long time. Although its power consumption performance is not a very core parameter, it cannot be ignored.

The actual power consumption of F-655FCV is close to 9W at the lowest gear; close to 12W at the second gear; and close to 50W at the highest gear.

The noise index is an important parameter that affects the comfort of an air purifier, especially during sleep. A purifier with excessive noise may seriously affect the user's normal rest.

In a room with an initial ambient noise of 59.5dBA, the F-655FCV was started at the first gear and the noise was measured at 62.6dBA at a distance of 50 cm from the front panel; the instrument reading at the second gear was 63dBA; and at the highest gear the instrument reading was 73.1dBA.

From a subjective listening perspective, the noise of the F-655FCV in the first and second gear modes is very, very slight. The sound of the airflow can only be heard within a distance of 1 meter. If the distance is beyond 1 meter, the sound will not be noticeable even in the dead of night. In the third gear, which is the highest gear, the noise of the whole machine will increase significantly. The main reason is that a lot of noise will be generated when the airflow is blown out at high speed. Therefore, this mode is only suitable for quick purification in a short period of time, and is not suitable for use at night or on ordinary days.

● PM2.5 purification effect

We use cigarette smoke as a standard pollutant test source for PM2.5 purification effect. The room is about 18 square meters and the ceiling height is 2.8 meters.

The air quality was good on the day of the test, with an initial PM2.5 concentration of 45ug/m3 in the room. After the introduction of cigarette smoke, the PM2.5 concentration in the room soared to 512ug/m3, which is considered heavy pollution.

Five minutes after starting the F-655FCV, the instrument reading dropped to 62.5ug/m3. At this time, the machine also switched back from the highest air volume to a smaller, quieter gear.

After purifying for about 5 minutes, the PM2.5 particle reading of the instrument dropped to 29ug/m3, which is lower than the initial value of 45ug/m3, proving the powerful filtering effect of F-655FCV.

Summarize:

The CADR value of F-655FCV is 310m3/h. From our actual test results, it is definitely a mid-to-high-end large purifier with a large clean air volume. Its appearance is more fashionable and modern than Panasonic's previous purifiers, and it is more suitable for users of large households. Its unique nanoe nano-water ion active sterilization technology can provide an extra line of defense for our health in addition to purification, which is also a selling point not to be missed. The PM2.5 pollution indicator on the front panel can use different colors to prompt the user of the current air condition, which is also very convenient for users to grasp the home air condition in real time, which is very convenient.
