3M electric fan electrostatic filter 12 inches 3 pieces

【3M】Special static filter for net breathing electric fan -12 inches (3 pieces) ◆Efficient filtration: the same electrostatic treatment principle as N95 mask, effectively adsorbing pathogens in the air ◆Easy and convenient: paste the filter directly on the back of the fan without cutting, which can upgrade the electric fan equipment ◆No power consumption: taking into account the filter power and air permeability, does not reduce the circulation capacity of the fan body ◆Unique permanent electrostatic fiber technology—effectively adsorb small bad molecules ◆Antibacterial fiber material: inhibit the growth of bacteria ◆Special non-woven fabric weaving method: This technology has a world patent, which can make clean air per unit time and good circulation efficiency without causing additional burden on the body ◆Exclusive patent: 3M patented process, BMF micro-woven meltblown technology, permanent positive and negative charge electrostatic treatment on superfine fibers ◆Imported filter material: The filter material of the electrostatic air filter is originally imported from the Netherlands, with excellent filtering efficiency and guaranteed quality ◆In order to ensure the filtration efficiency and avoid the burden on the circulating body, according to the use environment, regular replacement of about 2-3 weeks to maintain the best filtration efficiency Precautions: ◆The filtering efficiency of the electrostatic air filter mainly comes from the electrostatic force. During the use, the electrostatic force will gradually disappear, and the number of particles that the filter can carry will gradually decrease; in addition, when the electrostatic filter accumulates When too much particles are filtered out, the air permeability of the filter will be reduced. Please be sure to replace it regularly to ensure air quality ★This product is a consumable, once opened and used, it cannot be returned.★ ◆Model: SF123 ◆Contents: Electric fan electrostatic filter x 3 ◆Packing size: 27*15*1 cm
