In the world of air quality management, filters play a crucial role in removing pollutants and contaminants from the air. Among the various types of filters available, F7 filters have gained significant attention in recent years due to their high efficiency and effectiveness. But what exactly are F7 filters, and how do they work? In this article, we will delve into the world of F7 filters, exploring their definition, benefits, applications, and more.
What are F7 Filters?
F7 filters are a type of air filter that belongs to the ISO 16890 standard, which is a globally recognized classification system for air filters. The ISO 16890 standard categorizes air filters into four groups based on their efficiency in removing particulate matter (PM) from the air. F7 filters fall under the “ePM1” category, which means they are designed to capture at least 50% of particles with a diameter of 1 micron or less.
How Do F7 Filters Work?
F7 filters work by using a combination of mechanical and electrostatic forces to capture particles from the air. The filter media is typically made of a synthetic fiber, such as polyester or polypropylene, which is designed to attract and hold onto particles. The filter media is usually pleated or folded to increase its surface area, allowing it to capture more particles.
When air passes through the filter, the particles are drawn to the filter media, where they are trapped by the mechanical and electrostatic forces. The filter media is designed to capture particles as small as 1 micron, including dust, pollen, mold, and bacteria.

What are F7 filters and how do they work?
F7 filters are a type of air filter designed to capture 99.97% of particles as small as 0.3 microns, including dust, pollen, and other airborne allergens. They work by using a combination of three mechanisms: interception, impaction, and diffusion. Interception occurs when larger particles are caught in the filter’s fibers, while impaction happens when mid-sized particles are forced to change direction and stick to the fibers. Diffusion occurs when smaller particles move randomly and come into contact with the fibers, where they are trapped.
The unique design of F7 filters allows them to capture a wide range of particle sizes, making them effective at removing airborne pollutants and allergens. This is especially important for people who suffer from respiratory issues, such as asthma, or for those who want to improve the overall air quality in their homes or workplaces. By using an F7 filter, individuals can breathe easier and enjoy a healthier environment.
What is the difference between F7 and HEPA filters?
F7 filters and HEPA (High Efficiency Particulate Air) filters are both designed to capture airborne particles, but they have some key differences. HEPA filters are designed to capture 99.97% of particles as small as 0.3 microns, while F7 filters capture 99.97% of particles as small as 0.3 microns, but with a lower pressure drop. This means that F7 filters can be used in systems with lower airflow rates, making them a good option for smaller spaces or systems with limited airflow.
Another key difference between F7 and HEPA filters is their MERV rating. HEPA filters typically have a MERV rating of 17 or higher, while F7 filters have a MERV rating of 13-15. This means that HEPA filters are more effective at capturing smaller particles, but F7 filters are still highly effective and can be a more affordable option for many applications.
What are the benefits of using F7 filters?
Using F7 filters can have a number of benefits, including improved indoor air quality, reduced allergy and asthma symptoms, and increased energy efficiency.
