Celrith stainless steel oil removal filter mesh is a multi-layer grease and odour control filter for range hoods and kitchen exhaust systems. It captures heavy oil particles and cooking odours using a 304 stainless steel frame and front cover, aluminium foil micro-mesh, flame-retardant polyester fibre, and an activated carbon layer. It is designed for ductless recirculating range hoods, commercial kitchen exhaust purification systems, and European-style top or side suction hoods.
Cooking generates two burdens that are easy to underestimate: grease and odour. Grease leaves the pan as fine droplets and sticky vapour. It condenses on cooler surfaces as a persistent film that traps dust and becomes a food source for microbes. Odour is harder to see but travels further. Cooking smells, pungent spices, and smoke can spread through open-plan kitchens and recirculate in ductless hoods, leaving a lingering smell in living spaces.
In recirculating systems, the problem compounds because air is returned to the room. Without effective filtration, grease and odour are simply redistributed. Over time, this affects indoor air quality and the cleanliness of nearby surfaces. For commercial kitchens, the contaminant load is higher and more continuous, so filtration needs to hold up under heavier use.
When grease and odour are not captured, the load transfers to the equipment. Grease builds up on fan blades, motors, and duct walls. This buildup can reduce airflow, increase motor effort, and create a fire risk if not managed. In recirculating hoods, odour that passes through the filter returns to the kitchen, so the hood appears to work but leaves the air unchanged.
For commercial exhaust systems, grease reaching ductwork can increase cleaning frequency and maintenance cost. The contaminants also affect the working environment, making kitchens less comfortable and potentially affecting nearby areas. Effective filtration at the source reduces this downstream load, protecting the equipment and maintaining air quality.
Celrith addresses the problem with a layered approach. The aluminium foil micro-mesh and flame-retardant polyester fibre work together to separate and capture heavy oil and grease. The activated carbon layer adsorbs cooking odours, including oily smoke and spicy smells. This dual-action design helps recirculating hoods return cleaner, less odorous air to the kitchen.
The filter is built on a 304 stainless steel frame and front cover, which provide structural strength and resistance to corrosion. The frame can also be made from high-strength aluminium profiles, with optional clips and handles to suit different hood models. The materials are selected for safety: the filter meets UL 900 Class 1 and Class 2 fire safety test certification, supporting use in applications where flame resistance is important.
Celrith offers 100% flexible customisation. Sizes, structures, filter media grades, frame materials, logos, and packaging can be tailored to your requirements. This makes it possible to fit the filter to specific range hood models or commercial exhaust systems without compromising on performance. The filter is suitable for open kitchens, commercial kitchens, and European-style hoods, whether top suction or side suction.

This filter is used by appliance manufacturers and brands that need a reliable grease and odour filter for their range hoods, particularly recirculating models. It is also used by commercial kitchen operators and exhaust system integrators who require effective filtration in high-traffic cooking environments. Property managers and facility maintenance teams may specify it for residential or commercial buildings where kitchen exhaust odour control is important.
Because Celrith supports custom sizes and configurations, the filter can be adapted to different hood designs, including European-style top suction and side suction models. Whether for a new appliance line or a replacement part, the filter can be tailored to fit.
Celrith products comply with REACH and RoHS environmental regulations, and compliance documents are available upon request. The company holds ISO 9001, ISO 14001, and ISO 45001 system certifications, and obtained IATF 16949 automotive quality management system certification in 2024. These certifications reflect a commitment to quality, environmental responsibility, and occupational health and safety.
Our in-house laboratory is accredited by CNAS (China National Accreditation Service for Conformity Assessment) and can issue test reports for filtration efficiency, dust holding capacity, and resistance. The manufacturing base covers 50,000 square metres, including 20,000 square metres of cleanrooms across six workshops. With over 20 years of experience in filter research and manufacturing, we have exported to Europe, the United States, Japan, and South Korea for more than two decades. We support OEM/ODM projects and have developed over 1,000 filtration solutions. Multiple automated production lines enable a monthly capacity of millions of pieces, and quality control follows IQC, IPQC, and OQC processes.
