According to the authoritative investigation report, in the hot summer, after the car is exposed to the sun outside, the release of formaldehyde/toluene, TVOC and other chemical pollutants in the interior of the car is 50 times higher than usual, resulting in a significant increase in the concentration of toxic substances in the car, which seriously threatens human health. Therefore, the on-board air purifier has become a hot commodity at present. Choose a practical one in the context of the smart market It has become the focus of attention. But at present, there are thousands of products of more than one hundred brands in the vehicle air purifier market, so what should ordinary consumers do in the face of the market situation of various categories?

  Today, the author brings a comprehensive comparison of the three popular car purifiers, Calm, Philips and Sharp, which not only enables consumers to better understand the car purifiers, but also provides consumers with the most valuable shopping reference.

Parameter comparison

Packaging comparison

For any product, packaging is the first impression to users. A good packaging can not only effectively protect the internal products, but also leave a good initial impression to users.

The package of Calm intelligent car air purifier is made of square cardboard, and the color is slightly dark black. The cardboard packaging box can effectively avoid the damage of internal products during transportation, and the sharp edges and corners are more eye-catching.

In contrast, the packaging of Philips and Sharp is inferior, which may be due to cost control and the use of soft corrugated paper packaging. The front of the package uses the vehicle use scenario as the cover picture, and the packaging of the two is satisfactory. The packaging of Philips and Sharp is more straightforward about the product, and Calm is very mysterious.

According to the official publicity, the function of Calm's packaging box is not limited to that. The cardboard box can also be used as a storage box for family or trunk. The black color is not only dirt resistant, but also a versatile color. It is very creative, but it does not rule out that there are references to "Solo One".

Appearance comparison

As a vehicle product, we should firmly grasp the pain point of "limited interior space". Therefore, it is not as large as the household purifier. The volume of the three devices in this horizontal review has been well controlled. But the product design is free.

First, let's talk about Sharp's FU-GEM1N-B purifier. We can't find many new ideas from the shape. The irregular square shape has an arc transition on the front panel, but it is a bit like an outdated CD player from any angle. In a word, it is "ugly", because the author is not a nostalgic person. Among the three, Sharp is the largest, made of pure plastic, and its workmanship can only be described as "hehe".

The cobblestone shaped Philips Yi ACA301, with symmetrical and convex grids on the left and right, is easy to associate with sound. There is only one power button in the whole body, and it also has the air volume adjustment function. The strip LED display light is the only human-computer interaction mode. The whole fuselage has a novel shape, which can be described as concave and convex. The streamlined fuselage is also more suitable for various corner environments.

Calm X1 adopts a disc shape. The fuselage increases the sense of hierarchy through circular dents. The metal concentric circle wire drawing on the top brings a strong metal texture to the whole product. The top of the air duct grille is an inductive touch key. Compared with the physical key, the inductive touch key has a longer service life and more sensitive control. The design of the physical key shape should be better for users to understand at a glance.

Use scenario comparison

In order to better adapt to the environment in the car, the car and purifier are placed in a variety of places to avoid occupying too much space in the car.

Calm X1 can be used to install the front instrument panel, front seat, rear seat or rear window shelf. In combination with the safety bracket buckle at the bottom of the fuselage and the car strap buckle, the user can instantly complete the change of the installation position, and the whole process requires no tools.

In contrast, the Sharp FU-GEM1-B is much weaker, and the fuselage has only one strap buckle, so the use scenarios are only front seats and rear seats. Due to the wide body of the purifier, the use position between the rear seats is very limited.

Although the use scenario of Philips ACA301 is similar to that of Calm X1, both of them are comprehensive players, but there is no strap buckle on the back of the body of Philips ACA301. Each replacement requires the use of tools to remove the original silicone pad and replace it with a unique strap bracket, which is limited in convenience, cumbersome in operation and insufficient in humanistic care.

Air duct comparison

In the air duct design, the three vehicle mounted purifiers are basically the same. The air inlet at the top of the machine and the air outlet at the side of the fuselage are adopted. Because there are many use scenarios for the vehicle mounted purifiers, and the various placement positions and fuselage attitudes are different, it is difficult to tell the design advantages and disadvantages of the air duct.

The Calm X1 purifier uses a single air outlet at the side of the fuselage. Sufficient fresh air flow can be ensured in the same direction.

Sharp FU-GEM1N-B extends the 20 ° caster angle design of the household purifier to this unique point. The wind shield with manually adjustable tilt angle can control the air flow direction to a certain extent, thus creating new air flow.

Philips ACA301 has designed the air outlet to be symmetrical from left to right. The large area of air duct makes the air flow more relaxed, and at the same time, it creates the air flow shape with the changeable fuselage.

Filter screen comparison

As the core part of the purifier, the quantity and material of the filter screen have a great impact on the purification effect. However, some manufacturers not only falsely label the filter screen but also exaggerate the purification effect in order to control costs. HEPA filter screen is adopted for the three filters in this horizontal evaluation. In fact, HEPA filter type air purifier occupies most of the market share by virtue of its mature technology, safety and reliability, low research and development costs and other characteristics.

Calm X1 filter screen is divided into upper and lower layers: the upper layer is MarkromolekuHEPA filter screen, which intercepts and filters fine dust, pollen, smoke, bacteria, viruses, and effectively inhibits bacteria, mold, viruses and other allergens. The lower layer is a catalytic activated carbon filter screen, which adopts a common honeycomb structure to absorb harmful volatile gases such as ammonia, formaldehyde, sulfur, acids and VOC.

With a double-layer separable design filter screen, Sharp FU-GEM1N-B separates the deodorization filter screen from HEPA filter screen. Since the deodorization filter screen can be cleaned repeatedly, it can be recycled. There is no common activated carbon filter screen, so it is difficult to deal with some volatile harmful gases.

Philips has added its own HESA technology on the basis of HEPA filter screen, which also has a certain removal effect on volatile gases. However, the entire filter screen is unusually tight, which is not conducive to the passage of air flow, and may lead to low filtering effect.

Motor comparison

Both Calm X1 and Philips Yidong vehicle mounted air purifier ACA301 use wing type centrifugal fans. Compared with the traditional cooling fan, the centrifugal fan can output more air volume with less space occupation, but it also makes more noise when the impeller has ash deposition or runs at high speed.  

Sharp FU-GEM1N-B uses a multi wing centrifugal fan. The shell of the multi wing centrifugal fan is formed by precision die stamping, electrophoresis treatment, beautiful appearance, and stable structure. The wind wheel has passed strict dynamic and static balance test, and it is stable in dynamic and rotation, with large air volume, high air pressure, small vibration and low noise. However, due to the large number of impellers, it is easy to accumulate dust, and the noise generated when the impeller has dust or runs at high speed is also greater.

Noise contrast

The impact of noise on users' work and life is obvious. Living in a noisy environment for a long time is also likely to cause neurasthenia and other symptoms. A noisy driving environment not only affects personal mood, but also endangers driving safety.

When the ambient noise is 46dB, the noise of the three purifiers under different wind forces is as shown in the figure above. In contrast, Calm X1 has the smallest noise, whether in the maximum wind force or the minimum wind force.

According to the "National Noise Standard", the areas less than 50dB in the daytime and less than 40dB at night belong to the optimal category 0 quiet area, while the areas more than 70dB in the daytime are equivalent to both sides of the urban trunk road. From the test results, the three products performed well, and only the Philips ACA301 was high under the maximum wind.

Purification efficiency comparison

From the test results, Calm X1 and Sharp FU-GEM1N-B have equal purification efficiency, but Calm's purification rate is better. Among the three, Philips ACA301 is slightly inferior, and the purification speed is slow, which should be related to the poor air flow caused by the tight filter screen.

Function comparison

In terms of function comparison, the word "rolling" can be used to describe it.

Calm purifier as a Of course, there is a unique APP that makes the operation more convenient. Although positioned as an on-board purifier, CalmX1 supports both home use and timing.

The unique active oxygen sterilization function will instantly enhance the product style by several orders of magnitude.

The functions of Philips and Sharp purifiers can best be described by the numbers "1, 2, 3". First gear, second gear and third gear have different values, different wind force, different purification speed and different noise.

If aromatherapy is regarded as a special function, Sharp purifier is also a highlight. Aromatherapy and HEPA filter screens are also used and consumed, so they need to be purchased additionally. However, some unqualified aromatherapy on the market may cause secondary pollution, so it is necessary to choose carefully.

summary

After horizontal evaluation and comparison, the car purifier products are not ideal. Even big brands like Philips continue to reduce the size of the home version, and do not return to the real needs of car owners. At this time, the vehicle mounted purifier market urgently needs the injection of fresh blood. Under the influence of the smart trend, it broke through the dilemma of the reduced version and stepped into the smart; At the same time, to break the price barrier of big brands, big brands should learn from some entrepreneurs.

As a rising star, Calm purifier has exceeded the traditional vehicle purifier in appearance, practicability and comprehensive performance by a lot, even showing a trend of comprehensive compaction, returning to the real needs of the owner. No matter what the effect is, at least this is the future development direction of the vehicle purifier, and as a price issue that consumers are most concerned about, The Calm purifier has also been well controlled, and the price of 999 is also a good choice.
