Have you noticed that the discussion on haze has become less and less popular in recent years. Nowadays, air purifiers are changing from simple competition parameters to subdivided functions. In this round of reshuffle, small and medium-sized manufacturers with insufficient R&D strength and technical reserves have basically been eliminated, and most of the remaining ones are big brands with two brushes. Today we found 5 so-called large-brand mid-to-high-end air purifiers to conduct a first-stage comparison and evaluation to see what innovations they have.
Product introduction
These five air purifiers are Honeywell KJ460F, Bruyal 5440i, Bisheng Air 320, Ecovas Qinbao AVA, and Dyson Air Purification Fan HP09. These five brands cannot be underestimated. Let’s briefly introduce them.
Honeywell , a world's top 500 company, has a wide range of product lines. In addition to making great achievements in the field of high-tech, it also has a large number of military business. The price of this KJ460F is 3,599 yuan.
Bruyal, a brand from Swedish , focuses only on air filtration systems, and has always had a good reputation in the industry. The price of this 5440i is 3,399 yuan.
心网, a century-old enterprise, a giant in the North American floor cleaning industry, and the number one brand of vacuum cleaners in North America. We also conducted a review of Bisheng floor washing machine some time ago. If you are interested, you can take a look. The price of this Bisheng Air 320 is 3,590 yuan.
Ecovacs, a company in my country, is known as the "strongest sweeping monk in A shares" and its stock has risen a lot this year. Ecova mainly focuses on robotic products, including sweeping robots, mopping robots, window cleaning robots, etc. This Qinbao AVA is priced at 4,399 yuan.
Dyson , everyone should be familiar with. The leading brand in the small household appliance industry has gradually developed into a synonym for the new middle class. The price of this HP09 is 6,490 yuan, without any discount.
P.S. All the above prices are subject to the price of a cat on November 23.
hardware configuration
In terms of hardware configuration, we have sorted out the parameters of these 5 products. The data comes from the e-commerce details pages and customer service consultations of each product.
In terms of key CADR values, Honeywell and Victory belong to the first camp, Bruyal and Ecovacs are slightly inferior, and Dyson's data is even lower. Of course, the data cannot directly determine the effect of use, so let’s conduct actual testing.
particulate matter purification test
In the purification comparison of PM2.5, we used 20g cigarette sheets, the main components are sawdust and sulfur , and they are placed in a small transparent sealed chamber with the purifier and air quality detector. The time from the beginning of ignition of cigarette sheets to the PM2.5 value drops below 10.
After the cigarettes were burned out, the fastest decline in PM2.5 was a must-win, and it was within 7 minutes. Following closely behind is Honeywell, which also has a good performance. Bruyal and Ecovas are a little inferior and they will achieve their goal in about 9 minutes. Finally, Dyson, as a fan, is indeed a bit difficult for it. Overall, Honeywell and Victory performed better in this round.
Formaldehyde purification test
In terms of formaldehyde purification, these 5 products also have their own secret weapons. Honeywell uses high-silicon hydrophobic HISIV molecular sieve for aldehyde removal, Bruyal uses DustMagnet dust polyionization technology for electron adsorption, Bisheng uses silicon oxide crystals and activated carbon, Ecovacs uses activated carbon mixed with activated carbon and polyamine polyamine reactants, and Dyson uses formaldehyde decomposition catalyst.
Have you been confused? In fact, the principle of aldehyde removal is quite similar, it is nothing more than adsorption and decomposition. Let’s conduct actual measurements directly. The chamber is still transparently sealed, and 500ml of formalin solution is placed in free evaporation.
Among them, the fastest purification efficiency is this yellow line, which means winning. The 6-minute time has dropped below the national standard of 0.08.The purification efficiency of the three models, Honeywell, Bruyal and Ecovacs, is relatively close, and it takes about 10 minutes to drop to the national standard. Finally there was Dyson, with almost no movement in the first 5 minutes. As the same thing, as a fan, it is too difficult for it.
Noise test
In terms of operating noise, there are certain requirements for fan and air duct design. We conducted noise detection on the minimum and maximum gears of the five purifiers at a distance of 1 meter.
In the minimum gear, Honeywell, Ecovacs, and Dyson, all performed well, with only more than 30 decibels, which was almost impossible to hear. In the maximum gear, Bruyal and Dyson will perform better, under 60 decibels, and will not feel noisy.
product design
The five products also have great differences in design. Honeywell has a relatively traditional design idea, with air inlet on both sides and air coming out on the top, which looks like a purifier. The reason I say this is because none of the remaining 4 units look like purifiers.
Bruyal and Bisheng, both products are optimized for the appearance, use fabric surface, and then matched with four tripods, which have their own properties of home decorations. Especially Bisheng, this one is somewhat similar to the speakers of Boao BO.
This product from Ecovacs is a movable purifier with a fan on top, a filter in the middle, and a barrier-avoiding and mobile module at the bottom. When the sensor senses that the air quality becomes worse, it will run over to purify itself.
This product from Dyson is called an air purification fan. The point is the fan, and purification is its auxiliary function. The upper part is the classic leafless fan shape, and the lower part is the fan and filter.
Use cost
filter as a consumable that needs to be replaced regularly, and the price factor must also be taken into account. We searched for the corresponding filter prices in the flagship store of 5 products: the cheapest one is Dyson, which only costs 200 yuan, and the remaining few are between 500 and 600 yuan, which is at the mid-stream level.
If you are in an area with poor air quality, it is recommended to replace the conventional P4 and F4-level filters in about half a year. Areas with slightly better air quality are generally OK to change once a year.
Usage Experience
Next, let’s talk to you about the user experience of these 5 purifiers:
Honeywell. In fact, this purifier is relatively traditional, it only focuses on the functional point of purification, and does not have much innovation in product design and user experience.
Bruyal, we can see that we have put some effort into product design, and the addition of fabric makes the whole machine look more textured. But the problem is that its buttons and display area are really too small, which is slightly inconvenient to use.
must win. In my personal opinion, this purifier is the most beautiful among the five models. The fabric surface and wooden pedestal are just right, and it finds a balance between technology and home. Although the control and display of
also has been subtracted, the user experience is not discounted, so Bruyal should learn it. There is only one button in the whole machine. Press the start button, rotate and adjust the gear position, and dot matrix gear position display, which is practical and advanced. The problem with winning is the noise. The noise in the small gear is acceptable, but it is indeed a bit noisy under the highest gear.
Ecovacs, its advantage is that it can move freely in multiple rooms, suitable for use scenarios where only one purifier is available in a family. Thanks to Ecovacs' accumulation in the robotics industry over the years, its path planning and obstacle avoidance capabilities are excellent.
But its disadvantages are also obvious. First, it is the noise problem. In addition to purifying noise, there is also mobile noise; second, it is the battery life and power consumption problem. The movable design and small body will definitely compress the output of the machine. Whether this design is put before the horse needs to be considered.
Dyson, its advantage is its diversity of functions, it can blow air, regulate air, heat, and purify it, and use multiple uses in one machine. But unfortunately, purification is its weakest link. If it is from the perspective of purification effect, the cost performance is very average, so it is recommended to consider it carefully.
summary and recommendation
or above are comparison and evaluations of 5 high-end purifiers. I hope it will be helpful to everyone. For these 5 big-name products, we can give each product a keyword:
Honeywell is tradition, Bruyal is design, must-win is performance, Ecovacs is innovation, and Dyson is diversity, each with its own advantages.
We have also made a table for the above round comparison. If you have any needs, you can refer to it.
will eventually return to personal needs. I hope that efficient purification will be more prominent; if I want to experience new forms of products, Ecovacs will be more interesting; if there is a demand for fans and heating, Dyson will be more useful; you can learn more about it according to your needs.
