HEPA, which stands for High Efficiency Particulate Air, is a designation used to describe filters that are able to trap 99.97 percent of particles that are 0.3 microns. Most modern HEPA filters consist of interlaced glass fibers that are twisted and turned in myriad directions to create a fibrous maze. As particles traverse this web, they’re taken out of circulation in the following ways:
Direct Impaction: Large contaminants, such as certain types of dust, mold, and pollen, travel in a straight path, collide with a fiber, and stick to it.
Sieving: The air stream carries a particle between two fibers, but the particle is larger than the gap, so it becomes ensnared.
Interception: Airflow is nimble enough to reroute around fibers, but, thanks to inertia, particles continue on their path and stick to the sides of fibers.
In the past four years from 2014 to 2019, global HEPA Filters revenue market
scale was from 1483.5 million dollars to 1756.4 million dollars. It is estimated to reach 1832.6 million dollars by 2019 and 2361.2 million dollars by 2023, with the CAGR of 4.31% in terms of revenue over the period 2019-2025.
The HEPA Filters consumption volume was about 23.5 million Units in 2018 and is expected to reach about 28.7 million Units in 2019 and about 42.8 million Units in 2025, growing at a CAGR of 5.85% from 2019 to 2025. North America sales volume accounted for the largest market share of 33.96% in 2018, followed by the Europe and APAC.
At present, the manufactures of HEPA Filters are concentrated in North America, Europe, Japan, China and so on. North America is the largest sales revenue area in the world, which occupied about 36.81% revenue market share in 2018. The global leading players in this market are Camfil, American Air Filter, Freudenberg, Donaldson Company, etc.
The HEPA Filters are mainly used in Residential, Commercial and Industrial. In 2018, industrial application occupied 45.65% sales market share in HEPA Filter market.
For forecast, the global HEPA Filters revenue would keep increasing with annual growth rate with about 4.3%. The advantage of HEPA is that the technology is mature, and because of the physical filtration method, secondary pollution will not be formed. High requirements for materials. Another challenge is the maintenance costs that users pay more attention to. But with the awareness of environmental protection, we tend to believe that this industry still has a good future, considering the current demand of HEPA Filters.
