　　Which air purifier to choose?

　　In fact, before choosing an air purifier, first remove the products you need. If the main dust removal is dust removal and purification, formaldehyde removal air purifier with aldehyde removal device is mainly used... The above product types and structures can be used in combination when looking at the equipment.

　　Secondly, when purchasing an air purifier, you can focus on the four parameters of the product, namely CADR value/CCM value, energy efficiency value and noise value. Generally speaking, the higher the CADR value/CCM value and the energy efficiency value, the faster the product purification speed, and the lower the noise, the better the experience. Of course, we can’t just look at one parameter when buying an air purifier. It is a product that combines multiple factors to achieve three highs and one low.

　　Extended reading: How to choose a suitable purifier

　　There are two hard indicators when choosing an air purifier

　　One is the number of air changes required for indoor air, that is, the air volume required by the built-in fan of the air purifier. The standard is 5 air changes per hour in the applicable area.

　　The other is the purification performance index-Cleanair Deliveryrate (CADR), m3/h, the higher the CADR value, the better the purification efficiency of the product.

　　Tip 2: Know the applicable area of the selected air purifier

　　The main reference index for consumers to buy and use air purifiers is the applicable area, that is, the indoor area that the air purifier can use. The scope of application of an air purifier is closely related to its ability to remove particulate matter (that is, the amount of clean air). The general applicable area is divided into 30 square meters, 30-50 square meters, 51-99 square meters and more than 100 square meters.

　　Tip 3: Choose quality instead of price

　　At present, the prices of air purifiers in major shopping malls and online stores vary greatly, ranging from 100 yuan to yuan. Many people may think that the higher the price, the more comfortable to use an air purifier, but the higher the price, the better the effect of the air purifier?

　　Experts pointed out that the price difference of air purifiers is mainly due to two factors: applicable area and material cost. At present, there is no comprehensive evaluation method for the purification effect of air purifiers, and there is no uniform price standard for air purifiers on the market. The price of an ordinary household air purifier is around several thousand yuan, but the most important thing is to look at its effect and quality.

　　Tip 4: You need to consider the issue of replacing consumables in the future

　　Many consumers now only pay attention to the effect of air purifiers, often neglecting the need to change consumables. Consumables are the main filtering equipment of air purifiers, such as carbon nets, HEPA nets and so on. Because consumables are important to air purifiers, when purchasing, do not consider the price and service life of the consumables, but also consider the way the consumables are purchased. There are various air purifier consumables on the market, with different brands and models, but most of them are HEPA nets and carbon filters.

　　Experts pointed out that many consumers choose air purifiers that do not require replacement of consumables in the later period, but there is a big misunderstanding. Because general consumables have a service life, ignoring the direct impact of consumable replacement is to increase capital cost, time cost, and affect the purification effect.

　　Tip 5: How to maintain the air purifier

　　Experts remind consumers that if the air purifier does not clean the filter for a long time, it will become a breeding ground for bacteria. Each purifier has several layers of filters with different functions. For example, the filter is very dirty and cannot be washed with water, so replace it with a new one. Thoroughly clean the front filter of the layer once a month. In some air purifiers, the layer is a carbon filter, which needs to be exposed to the sun for more than 24 hours within half a year. The second and third-layer composite filters are replaced every six months, and every three months for families with poor environment and dust. In addition, the consumables should not be replaced only according to the indicator lights of the consumables, but should be replaced regularly according to the degree of environmental pollution. The filter should be changed frequently, even if it is air, it cannot be half a year, otherwise harmful substances will be released after the filter material is saturated and become a "pollution source".
