How to choose an air purifier, how to choose an air purifier

What's worth buying is the value of the help you buy.

<> "The premise of people's healthy life is to have a clean air environment. In the face of increasingly serious air pollution, people have chosen to buy air purifiers. It is loved for its ability to improve air cleanliness.

There are many types of air purifiers on the market, so how do you choose one?

How to choose an air purifier.

First, the problem of power consumption.

The less power an air purifier has, the less power it consumes, the less power it consumes. In addition to power, some air purifiers are equipped with automatic forms, which can automatically adjust the air volume according to indoor conditions, so as to achieve the purpose of saving electricity, and can also extend the life of the filter screen.

Second, the body structure.

At present, there are two kinds of air inlet and outlet air of air purifier, one is the air inlet at the back and the air outlet at the front, which is easy to blow up the dust on the floor and aggravate the dust in the indoor air; The other is the air inlet and air outlet below or behind: this can suck the dust on the floor into the air purifier and blow out fresh air from above after purification, which plays the role of "cleaning the floor", especially if there is a baby at home, the baby likes to climb on the ground, and needs to pay more attention to floor hygiene.

3. Safety performance.

Air purifiers that use Shenqi electrostatic precipitator and authentic negative ion technology will produce ozone, which is often referred to as the secondary pollution problem of air purifiers. An appropriate amount of ozone can kill bacteria and viruses and synthesize gaseous pollutants, but excessive ozone is harmful to the body, affects the lungs, causes asthma, and can cause cancer in serious cases. At present, the safe and effective technologies are HEPA net technology and activated carbon technology, electrostatic precipitator and authentic ion technology will produce ozone, and air purifiers using HEPA net filtration and activated carbon technology should be selected when purchasing.

1. Attention should be paid to the performance characteristics of the product. When purchasing an air purifier, you should check the nominal clean air volume, cumulative purification volume, purification energy efficiency and noise of the air purifier, from which you can see what kind of pollutants the air purifier has and how good the purification ability is.

2. You should consider your own use environment and the effect you want to achieve. For newly renovated houses, the most important thing to remove is formaldehyde, toluene and other gaseous pollutants, at this time, we should pay attention to the purification effect of the product for gaseous pollutants, and give priority to the purchase of products that are clearly marked with formaldehyde clean air volume and formaldehyde cumulative purification amount. For places that deal with haze weather, you should give priority to the amount of clean air and the cumulative purification of particulate matter of the product, and choose an air purifier that suits your needs.

3. At the same time, the purification capacity of the air purifier should be considered. If the space is larger, you should choose an air purifier with a large amount of clean air, generally speaking, a larger air purifier has a stronger purification capacity and the more noise. When choosing a purifier, you can refer to the applicable area or clean air volume marked on the air purifier manual or nameplate, and the relationship between the two is about:

Usable area = particulate matter.

4. Consider the service life of the air purifier. Air purifiers require frequent maintenance during use, and the key parameter that affects the service life of air purifiers is the cumulative purification volume. Depending on the type of air purifier, the air purifier needs to be replaced or cleaned regularly.

At present, electrostatic air purifiers need to clean the filter element regularly, and other purifiers generally need to replace the filter.

5. When purchasing an air purifier, you also need to pay attention to the purification energy efficiency and noise of the air purifier. For purifiers with the same amount of clean air, the higher the purification energy efficiency, the more electricity saving. Since the air purifier is a place where people work and live for a long time, special attention should be paid to the noise of the air purifier, and the noise of the purifier can be checked on the nameplate or the noise on the manual.

Generally speaking, the greater the amount of clean air, the greater the noise of the air purifier, the current air purifier noise is generally 45 70db(a), and it is necessary to pay attention to whether the product is wrongly labeled when encountering a particularly small nominal product.

1. Look at the demand.

Some homes may simply do it to get rid of odors, but others do it for filtration. Another aspect is to select the corresponding purifier according to the needs of the space, such as how large the space is and whether each functional area needs to achieve the purpose of purification. These needs are closely related to the purchase of purifiers.

2. Look at the purification method.

There are generally two types of air purifiers on the market, one is an electrostatic air purifier and the other is a mechanical air purifier. The mechanical type uses mechanical wind to blow dirty air into the filter, and then uses the filter to absorb some pollutant particles, so as to achieve the effect of purifying the air.

3. Look at the difficulty of maintenance.

Generally speaking, it is easy to repair, and the air purifier replaced by Filter NetEase is our first choice, because if the purifier is easy to maintain, we can solve problems in time, and the corresponding service life will be greatly extended.
