Purification equipment :
First, for the filter material: good filter material (currently recognized by the world's good HEPA high-density filter material) the ability to adsorb more than 0.3 microns of pollutants up to 99.9%; if the indoor smoke pollution is heavy, you can choose dust removal A better air purifier.
Second, on the purification efficiency: the room is larger, should choose the unit to purify the air purifier; for example, 15 square meters of room should choose the unit to purify the air volume of 120 cubic meters / hour of air purifier;
Third, the service life: As the purification filter tends to be saturated, the adsorption capacity of the purifier will decrease, so consumers should choose a purification filter with regenerative function (including highly efficient catalytic carbon) to prolong its life.
Fourth, the room layout affects the purification effect: the air purifier has a 360-degree ring-shaped air inlet and outlet, and also has a one-way air inlet and outlet. If the product layout is not restricted by the room layout, the ring type inlet and outlet design should be selected. product.
V. Demand: Select the air purifier according to the type of pollutants to be purified. HEPA has a strong purifying function for soot, suspended particles, bacteria and viruses, and the catalytic activated carbon has better effect on the purification of odor and harmful gases.
Sixth, purification equipment after-sales service: purification filter after the failure of the gallbladder needs to be replaced by the manufacturer, so consumers should choose after-sales service manufacturers to produce products.
