The Consumer Council tested the styles on the market, and one of them received a 5-star out of a total rating. In addition, the cheaper styles did not necessarily perform poorly!
(Consumer Council)
The Consumer Council and the Electrical and Mechanical Services Department have cooperated to test 4 types of two-in-one air purification dehumidifiers (4688 to 5980 yuan) and 10 traditional dehumidifiers (1899 to 5480 yuan). The styles are as follows:

Dehumidification performance:
The dehumidifying performance is undoubtedly the most important function of a dehumidifier. Under the "standard environment (26.7 degrees, relative humidity 60%)" and "manufacturer's usual environment (30 degrees, relative humidity 80%)", the performance of each sample is different. .

However, under the "customer's customary environment", the dehumidification volume of the "Famous Famous" sample was more than 10% (14.6%) lower than the claimed value, and the Consumer Council has forwarded it to the Customs for follow-up. "Famous Famous" responded that the test results differed by the input voltage.
energy efficiency
Energy efficiency is also an important part of a dehumidifier. The higher the value, the more power saving, the higher the daily dehumidification amount measured by the dehumidifier at a higher temperature and humidity. Although all the samples are marked as level 1 energy efficiency, according to the results of this test, Jiali Gala actually only reached level 2.
The energy efficiency test results are as follows:

Air purification performance
This time, it also tested the air purification performance of 4 two-in-one air purification dehumidifiers, including the removal of particulate matter (the ability to remove smoke and dust from Egyptian pollen) and the removal of formaldehyde. The results showed that the purification speed of the four samples was very uneven, and the fastest and slowest particles could be cleared up to 2 times. In addition, all samples could reduce the concentration of formaldehyde, but the speed was quite slow.
The overall performance is as follows:
Safety test
Of the 14 samples, 10 samples passed all safety tests, but the instructions for "Kusatsu Kusatsu", "Hitachi Hitachi", "Positive Plus Plus Minus Zero" and "Famous Famous" are slightly inadequate. Warning words.
Overall performance:
Among the 14 samples, the total score of most of the samples was 3 to 4 and a half stars, but one got 5 stars, which is the highest score in this test. In addition, based on the overall evaluation, expensive goods may not necessarily be the best.

There are many types of dehumidifiers. The Consumer Council pointed out that users who do not require particularly high dehumidification speed can choose "PlusMinus Zero XQJ-C010" because it takes up less space and is relatively cheap.
Consumer Council purchase 5 tips for dehumidifier
1) It is not advisable to compare the non-standard environmental values customarily used by manufacturers. Reference should be made to the energy efficiency, dehumidification capacity and energy level indicated on the energy label. The higher the energy efficiency under the same dehumidification capacity, the more power-saving and dehumidification capacity. The higher, the faster the dehumidification speed.
2) Consider the living environment and personal needs to purchase a dehumidifier with a suitable dehumidification capacity. If the living area is large, offshore or the environment is more prone to humidity, a model with a higher dehumidification capacity can be selected.
3) If you buy a 2-in-1 air purification dehumidifier, you should also consider the cost of replacing the filter at the same time (the above-mentioned 4 models in the first 5 years and the first 10 years will cost more than 4,000 to 7,000 yuan).
Consideration must be given to the cost of replacing the filter in the future. (Consumer Committee)
4) Because different manufacturers have different deadlines for parts storage, you should clearly check the relevant maintenance period and parts storage period before purchasing.
5) Pay attention to the implementation of new energy efficiency rating standards, and choose a more energy-saving and environmentally friendly dehumidifier.
