The HEPA air filters are the most effective filtration medium for pollutants such as smoke, dust particles, mold spores, dust mites, airborne particles, and bacteria, with a filtration efficiency of 99.97% or more for particles with a diameter of 0.3 microns (PM0.3) or more.
And HEPA filter development is relatively mature is internationally recognized as the best high-efficiency filtration equipment, so it is commonly used.
Compared with traditional filters, HEPA filters have high filtration performance and large dust-holding areas, which can purify the air of an ample space at once.
It has high air resistance, dust-holding capacity, and filtration accuracy. This air filter is also characterized by the fact that only air can pass through, but fine particles cannot, thus guaranteeing its filtration efficiency.
Therefore, the removal efficiency is exceptionally high, and bacteria, smoke, and airborne pollutants are effective filtration media.
However, HEPA can’t do anything about harmful chemical gases and needs to be replaced and maintained regularly during use.
Let’s analyze whether HEPA filters are worth buying or using from 3 specific application scenarios
1. Living environment
This depends on your current air quality, the number of indoor pollutants in the air, the type, how much air is needed, and the danger to the population.
The primary contaminants in a family residence are hair, smoke, allergens, pet dander, small particles, bacteria, mold, etc. HEPA filters can effectively remove them and improve indoor air quality. This protects indoor people, especially those with allergies and asthma symptoms, and other respiratory symptoms.
The most common air purifiers today use a large number of HEPA filters, and only TURE HEPA filters are able to trap dust and filter out airborne particulates and harmful pollutants. Improve air quality and give people healthier air.
2. Commercial facilities and public places
Many office equipment, and dense crowd, are the source of air pollutants, smoke, hair, and volatile organic compounds VOCs, and all need true HEPA filters to filter and remove.
The HVAC system in commercial environments also uses multi-stage filtration systems that use primary or intermediate efficiency air filters in front of HEPA filters. Using a HEPA filter will be trapping dust and removing airborne particles, larger particles, and airborne contaminants in air ducts.
3. Industrial production sites
Many high-precision products have high requirements for 0.3 microns of small particles in the air in the production workshop, such as pharmaceutical, semiconductor, electronic, and other industries with very advanced HEPA filtration systems, so HEPA filters are essential for these industries.
In the face of the diversity of HEPA filters on the market, how do customers choose the right product?
First of all, from the perspective of their own purification needs
Here mainly depends on the application in what industry, what scene, what is the quality of indoor air requirements, to a relatively clear understanding of what particles in the air, what indoor air pollutants, and what is the desired air quality to target the choice of HEPA filtration system to purify the air.
The design of the filtration system or ventilation system, Combined air flows, air passes, and clean air delivery rate, if necessary, needs a multi-stage filtration system that is the primary – medium – high-efficiency filtration. For example, multi-stage filtration is more common in the semiconductor and liquid crystal display industry.
In the residential or household sector, multi-stage air filtration systems is also often used, most typically in air purifiers or air cleaner, where the core of the filtration system is a multi-stage filtration system consisting of a primary filter, activated carbon, and a HEPA filter. The activated carbon filter can remove volatile organic compounds.
In addition, floor sweepers and vacuum cleaners are equipped with HEPA filters to filter dust, particles, hair, food residue, etc. HEPA filter helps to protect the machine’s motor and avoid secondary pollution of indoor air.
Second, to start with product quality considerations.
The excellent quality HEPA filter can only use for a more extended period, and the chance of problems will be smaller.
When checking the quality, see the material of the HEPA air filter, see if the service life of the HEPA air filter is long, and how about the purification efficiency and purification effect. If they are better, such filters are worth choosing.
Finally, consider the environment of their use.
To a certain extent, the use of the environment affects the efficiency of the high-efficiency particulate air filter, considering aspects such as the temperature and humidity of the domain.
We suggest customers check the filter regularly for wear and tear in the later use process, and if too much dust has accumulated on the HEPA filter or it has reached its service life, it should be replaced with a new filter in time.
