YIDINGAIR FILTRATION
Product overview
What it is and where it fits.
The Yiding 3-in-1 cylindrical HEPA filter combines a pre-filter, an H13 HEPA layer and activated carbon fibre in one round cartridge. Dust, fine particles, smoke and odours are removed in a single pass, so there is one filter to stock and one filter to change.
It is used in air purifiers, laser and welding fume extractors, industrial vacuums and dust extractors, laboratory and hospital air cleaners and odour control units. Standard reference sizes are available, and any diameter and height can be built to fit your equipment.

Construction & performance
Three stages in one cartridge
An outer pre-filter captures hair, fibres and coarse dust; a pleated H13 micro-glass fibre HEPA layer removes PM2.5, pollen, bacteria-carrying particles and smoke; an inner activated carbon fibre layer adsorbs odours, VOCs and formaldehyde. Air flows from outside to inside.
Materials & options
Expanded-metal outer and inner mesh, galvanised or powder-coated. End caps in galvanised steel, stainless steel, ABS or PU, with one end open and the other open or closed. EPDM, neoprene or foamed polyurethane gaskets. HEPA grades H11 to H14; granular or honeycomb carbon on request.
Sizing & data
The reference sizes below are standard configurations; any diameter and height can be made to order. Airflow and pressure drop are rated per size and media combination and are confirmed on your quotation, together with configuration-specific test data.
Selection guide
How to choose.
Match the cartridge you use today
Send the outer and inner diameter and height, a drawing, a photo, a sample or the part number of your current filter. Any diameter and height can be made to order.
Choose HEPA grade and carbon for the job
H13 suits most purifiers and extractors; choose H14 where a stricter grade is specified. For heavy odour or VOC loads, more carbon or a granular or honeycomb carbon version can be specified.
Tell us the operating conditions
Airflow, target gases, temperature and humidity decide the media combination. Carbon performance drops in high humidity, so mention humid service.

FAQ
Common questions.
What does 3-in-1 mean?+
Three filter stages in one cartridge: an outer pre-filter for hair and coarse dust, a middle H13 HEPA layer for fine particles, and an inner activated carbon fibre layer for odours and gases. Air flows from outside to inside.
Can you make a replacement for my air purifier or fume extractor filter?+
Yes. Send the dimensions, a drawing, photos, a sample or the original part number, and we build the cartridge to fit your housing, including diameter, height, end caps and gasket.
How often should the filter be replaced?+
Typically every 6 to 12 months, or when airflow drops noticeably or odours return, depending on the dust and gas load.
Does the carbon layer remove formaldehyde and VOCs?+
The activated carbon fibre adsorbs odours, VOCs, formaldehyde and smoke smells. Capacity depends on the gas load, temperature and humidity; for heavy gas loads a granular or honeycomb carbon version can be specified.
