Airguard Envirocare G4 High-Loft Filter are de igned for reliable coar e particulate filtration in commercial and indu trial air handling y tem .
The G4 High-Loft Filter is designed for HVAC and ventilation systems where effective coarse particulate filtration is required. Its high-loft pocket construction provides increased media volume and filtration area, making it suitable for applications with regular dust loading.
The filter is used across office buildings, retail environments, hotels, hospitals, food industry facilities, leisure centres, paint shops, spray booths, automotive operations and allied industries.
It can be used as a primary filter or as part of a multi-stage filtration system to help protect downstream filters and air handling equipment.
The G4 High-Loft Filter uses high-loft filtration media formed into multiple pockets. This construction increases the available media area and allows the filter to retain airborne particulate while maintaining airflow through the system.
Standard and bespoke dimensions can be supplied to suit different filter housings and ventilation systems.

Common questions about G4 High-Loft Filter.
It is used for coarse particulate filtration in HVAC, ventilation, paint shop, spray booth, and industrial air handling applications.
Yes. It can be used as a primary filtration stage to help reduce particulate loading on downstream filters and equipment.
Yes. Airguard Envirocare can manufacture or supply G4 High-Loft Filters to suit non-standard filter housings.
A G4 High Loft Filter is a coarse-grade HVAC air filter designed to capture larger airborne particles before they reach downstream filtration stages. It is commonly used as a pre-filter in ventilation, HVAC and air handling systems.
The G4 classification is commonly associated with coarse filtration under the older EN779 classification system. For modern filter specification and comparison, the relevant ISO 16890 classification should also be checked, as the exact rating depends on the filter's tested performance.
A G4 High Loft Filter can be used in:
HVAC systems
Air handling units
General ventilation systems
Industrial air intake systems
Pre-filtration stages
It is particularly useful where larger dust and airborne contaminants need to be captured before finer filters.
Yes. The filter can be supplied as an OEM-equivalent or specification-matched replacement when the existing part number, dimensions, airflow and filter construction are provided.
A G4 High Loft Filter can act as a first-stage filter, reducing the amount of larger particulates reaching downstream F7, F8, or higher-efficiency filters. This can help reduce contaminant loading on later filtration stages.
Yes. Provide the required width, height, depth and application details for a custom or specification-matched replacement filter.
G4 High Loft Filter should be selected according to the environmental conditions stated in its product specification, including factors such as dust, moisture, salt, humidity, temperature and airborne contamination where applicable. The installed system and required filtration performance should be checked before selection.
Where G4 High Loft Filter is identified as Altair-compatible, Airguard Envirocare positions it as an OEM-equivalent or specification-matched replacement. Exact compatibility should be confirmed against the installed filter's part number, dimensions and required performance. The available FAQ material does not identify a specific gas-turbine air intake system for this product; use it only where its published dimensions, airflow and filtration requirements match the installed system.
