How to purchase car purifier？ As everyone pays more attention to theair environment in the car, many people plan to purchase car air purifiers. However, whether they need to choose the air purifier is all too daunting. Experts whether it is necessary to purchase and use car air purifiers and consider their needs. If the airconditioning filtration system of the vehicle is powerful and can be replacedin time, it can meet the demand for purification. Part1:see the relevant test or report Car purifiers have a mix of brands,but a high-quality, safe-to-use vehicle-mounted purifier should be certified through relevant parts and have related industry quality inspection reports or 3C certification. Such a car air purifier can only be used up to a higherutilization rate, a longer service life, and effective avoidance of overcharging, explosion, and other quality problems.
Part2:look at the adsorption principle 1. Adsorbate: Activated carbon and coconut shellare two common adsorbents. The two adsorbates have strong adsorption capacityand can adsorb formaldehyde, toluene, benzene and other chemical odors. 2. Filter: All car air purifiers have filters.However, some car purifiers use ordinary filters and have poor filtration. Thetruly high-quality filter should be a medical-grade HEPA filter with the functions of purifying exhaust gas particles, second-hand smoke particles, andPM2.5. The general filter has 3-5 layers, the more layers, the better thepurification effect. Some high-quality car purifiers contain multiple filters with different functions, including HEPA filters, negative ion filters, and nano-scale filters. 3. Negative Ions: Anions Negative ions can react with formaldehyde, benzene, etc., and decompose into carbon dioxide and water.Combined with positive ions of dust, dust, and PM2.5 in the air, they can land,which in turn purifies air quality. the goal of. The air purifier that buys theconcept of negative ions depends on how many units of negative ions arereleased by the built-in negative ion generator with in the unit of time. Ingeneral, the higher the negative ion concentration, the higher the purification efficiency. 4. photocatalyst technology: Photocatalyst can also decomposeformaldehyde, toluene and other chemical odor, is a relatively high-endautomotive purification technology. Vehicle purifiers, which usually containphotocatalyst technology, are relatively expensive. Part3:see the air volume If the purifying effect of the air conditioning filter on the car is relatively general, car air purifiers with better filtration effect, use of high-efficiency air filter (HEPA) or activated carbon, etc., can indeed purify the suspended particulate matter in the vehicle. However, due to the limitation of many factors such as volume andpower, its effect is relatively small in a short time. Compared to airconditioning in vehicles, there is a large gap in air volume. Purchasing products that have a large amount of air flow should be selected according to the actual space in the vehicle. With a large amount of air output and a largeamount of air through put, this car air purifier can make the air in the vehicleform a cycle in a shorter time, to enhance the purification effect. With doors and windows closed, the chemical hazardous substances in the car are not static. Due to the largenumber of adhesives used in the manufacture of automobiles, harmful substancessuch as formaldehy de will inevitably exist in different degrees. At the sametime, the release rate of chemical harmful substances in vehicle interiors will change with temperature, especially in summer when the temperature is high, the evaporation rate It may be higher than the purification speed of the purifier.Therefore, the purchase of products with a large amount of air flow is moreeffective for purifying harmful substances such as formal dehyde and benzene.
When choosing an in-vehicle purifier, do not choose a single-functionvehicle-mounted purifier. Instead, select a car purifier with various functionsby referring to the above criteria.Function superposition, purification effect is more ideal. Of course, there are many car purifiers on the market with additional features including aromatherapy and humidification. The function of humidification is better than that of aromatherapy. It can be used in conjunction with air conditioning in the summer to enhance the moisture in the vehicle. In the autumn and winter,the static electricity can be relieved and the air in the vehicle can be relieved from drying. Publish on 06/28/2018 by yechao, 296 hits. |
