First of all, consideration should be given to the environment and the effect to be achieved.General indoor air pollution is: 1. Allergens such as dust, virus, bacteria, mold and mite; 2.2. Inhalable organic volatile gas, such as formaldehyde, benzene, ammonia, etc.;3. Radioactive pollution caused by radon gas and its daughters released from strata and building decoration materials.So, choose air purify product, should consider its function and effect synthetically.
Secondly, the purification capacity of air purifiers should be considered.If the room is larger, you should choose the air purifier with larger air volume per unit time.Generally speaking, larger purifiers are more powerful. For example, a room of 30 square meters should be equipped with an air purifier of 120 cubic meters per hour.When choosing, you can refer to the sample or the description in the book to choose.
Third, should consider the service life of the purifier, maintenance is simple.If there are some products because of adopting the principle of filtration, adsorption, catalytic purifier use increases with time, saturation, filter bravery is air purifier to purification equipment capacity decline, need to clean and replace filter and filter, the user should choose regenerative ability of purification filter bile (including high catalytic activated carbon), to prolong service life.There are also some electrostatic products do not need to replace the relevant modules, as long as the regular cleaning.
Fourth, should consider the room pattern and the purifier of the match.Air purifier inlet and outlet wind design has a 360 degree ring design, or one-way.
Techniques of choose and buy
One, filter material.Good filtration materials (such as HE PA high-density filter) have a capacity of over 99.9% to absorb pollutants over 0.3 microns.
Second, purification efficiency.If the room is larger, an air purifier with a high air purifying capacity per unit should be selected. For example, for a room of 15 square meters, an air purifier with a unit air purifying capacity of 120 cubic meters per hour should be selected.
Three, service life.The adsorption capacity of the purifier will decrease as the purification and filtration bile reaches saturation, so consumers should choose the purification and filtration bile with regenerative function to extend its life.
Four, room pattern.The inlet and outlet of the air purifier has a 360-degree annular design, and there are also one-way in and out of the wind, if you want to put the product in the room pattern is not limited, you can choose the product of the annular in and out of the wind design.
Demand.According to the types of pollutants to be purified, air purifiers are selected. HEPA has a strong purification function for smoke, suspended particles, bacteria and viruses, and catalytic activated carbon has a better purification effect for odor and harmful gas.
Vi. After-sales service.After the failure of purification filter tank to the manufacturer to replace, so should choose the product of the enterprise with perfect after-sales service.
