Effect of thickness on oil fume filter performance

The oil fume filter can effectively intercept oil fume particles, grease and other substances produced during the cooking process, preventing them from entering the indoor air and reducing indoor air pollution. At the same time, it prevents oil smoke from entering equipment such as oil purifiers, reduces equipment from grease pollution and corrosion, and extends the service life of equipment. But what impact does thickness have on the performance of the oil fume filter? •Filtration effect: Generally speaking, a thicker filter can accommodate more filter materials or structures, which may improve the filtration effect and intercept more oil smoke particles. However, the specific degree of impact is difficult to express with exact data, because it is also related to many factors such as filter material and pore structure. For example, an increase in thickness may increase the interception rate of larger oil smoke particles from 70% to about 80%.

•Wind resistance: Increased thickness will lead to increased wind resistance, thus affecting air circulation. The suction power of the range hood may be weakened to a certain extent. For example, when the filter is thinner, the suction power is 15 cubic meters per minute. After increasing a certain thickness, the suction power may drop to 12 cubic meters per minute.

•Lifespan: Thicker filters may be relatively more durable because there is more material to withstand the adhesion and accumulation of oil fumes. But this is not absolute, it also depends on the quality and maintenance of the filter. Assume the normal lifespan of a thinner filter is 3 months, and a thicker one may extend to 4 months or more, but this is only a rough guide.


It should be noted that these effects are not absolutely linear, and different types and designs of oil fume filters will vary greatly. The actual situation will vary depending on the specific product and usage environment.
