In this article, we will discuss the different types of Mechanical Ventilation with Heat Recovery (MVHR) filters that are available in the market. MVHR systems are widely used in modern buildings for their energy-efficient ventilation and heat recovery capabilities. These systems are designed to provide fresh, filtered air while retaining the heat from the outgoing air.
The filters in MVHR systems play a crucial role in maintaining good air quality, and it is important to understand the different types of filters available to make an informed decision.
Types of MVHR Filters
G4 Filters
G4 filters are the most basic type of filter used in MVHR systems. They are designed to filter out large particles such as dust and pollen. These filters are typically made of synthetic fibers and are effective in removing larger particles from the air. However, they are not effective in filtering out smaller particles, such as mold spores and bacteria.
F7 Filters
F7 filters are a higher grade filter that can remove smaller particles such as PM10, pollen, and diesel soot. They are effective in filtering out up to 80% of these smaller particles, which helps to improve the overall air quality. These filters are made of synthetic fibers and are more efficient than G4 filters.
F8 Filters
F8 filters are the highest grade of filter available for MVHR systems. They are designed to filter out even smaller particles such as PM2.5 and are effective in removing up to 90% of these particles. These filters are made of synthetic fibers and are the most efficient type of filter for MVHR systems.
Activated Carbon Filters
Activated carbon filters are used in MVHR systems to remove odors and volatile organic compounds (VOCs) from the air. They are typically made of activated carbon granules, which have a large surface area that can absorb pollutants from the air. These filters are not effective in removing particles from the air and are often used in conjunction with other types of filters.
HEPA Filters
HEPA filters are the most efficient type of filter available for MVHR systems. They are designed to remove particles as small as 0.3 microns and are effective in removing up to 99.97% of these particles. These filters are made of tightly packed fibers and are used in environments where high air quality is required, such as hospitals and laboratories.
Choosing the Right Filter for Your MVHR System
Choosing the right filter for your MVHR system is important to ensure good air quality and system efficiency. Factors such as the level of pollution in your area, the sensitivity of the occupants, and the type of building should be taken into consideration when selecting a filter.
If you live in an area with high levels of pollution, it is recommended to use a higher grade filter such as an F8 or HEPA filter. For buildings with sensitive occupants, such as hospitals or schools, it is recommended to use a HEPA filter to ensure the highest air quality. For residential buildings, an F7 filter may be sufficient to provide good air quality while maintaining system efficiency.
Conclusion: MVHR filter types are crucial
In conclusion, MVHR systems are an effective way to provide energy-efficient ventilation and heat recovery in modern buildings. The filters in MVHR systems play a crucial role in maintaining good air quality, and it is important to understand the different types of filters available.
Choosing the right filter for your MVHR system is important to ensure good air quality and system efficiency. Factors such as the level of pollution in your area, the sensitivity of the occupants, and the type of building should be taken into consideration when selecting a filter.
