micronAir CF112 Cabin Air Filter (2021–Present) for BYD DOLPHIN – Activated Carbon

Your DOLPHIN breathes through a single cabin filter — and by the end of its first year that panel is a grey mat of dust, pollen and road film throttling your vents. This is the correct replacement: the micronAir CF112 activated carbon cabin filter, the catalogue-standard part for the DOLPHIN, in its micronAir retail box.

CF112 is the number that matters. It is micronAir's part code — the code workshops and parts catalogues use to identify the cabin filter for this car — and it exists because the DOLPHIN and the ATTO 3 are built on the same BYD e-Platform and share the same filter housing and panel. One CF112 panel services both cars. The media is the grey activated-carbon type shown in the photos: pleated particle filtration plus a carbon component that works on odours and exhaust gases, not just dust.

• The right code, zero guesswork — cabin filters are bought by part code, not by hope. CF112 is the established cross-reference for the DOLPHIN (2021–present) and ATTO 3 (2022–present) housing, so the panel that arrives is the panel your car takes.
• Activated carbon, not plain paper — the grey carbon-loaded media adsorbs traffic fumes, outside smells and volatile compounds on their way in. In queued traffic and tunnels, that is the difference between air that smells like the road and air that smells like nothing.
• Full airflow back — deep, even pleats give a large filtration area in a compact panel, and a fresh set of pleats removes the restriction your blower has been fighting. Vent output sharpens, demisting quickens, and the musty smell of a saturated old filter leaves with it.
• One panel, two BYDs — households and fleets running a DOLPHIN alongside an ATTO 3 stock a single part number. The shared fitment graphic in the photos shows both cars for a reason: same platform, same housing, same CF112.
• Minutes to change, behind the glovebox — the housing sits behind the glove compartment. Lower the box, unclip the cover, slide, click, done.

• CF: micronAir's cabin filter line — the prefix identifies the part as a cabin (pollen) filter in the micronAir catalogue.
• 112: the model code for this exact panel shape and housing — the number that ties the DOLPHIN and ATTO 3 fitment together across catalogues.
• Media type: activated carbon pleated panel — particle filtration for dust, pollen and fine soot, plus gas and odour adsorption from the carbon component.
• Cross-check: BYD's own shelf number for this shared filter is 1312461000; CF112 is the aftermarket catalogue equivalent workshops order by.

• Vehicle: BYD DOLPHIN, 2021–present (all battery and trim versions)
• Also fits: BYD ATTO 3, 2022–present — same e-Platform filter housing
• Part code: micronAir CF112
• Filter type: activated carbon cabin air filter
• Quantity: 1 panel — the car takes one
• Position: HVAC filter housing behind the glovebox

1. Empty the glovebox. Release its side damper and press the box's side walls inward so it lowers past its stops — the filter housing cover is right behind it.
2. Unclip the housing cover and pull the old CF112 panel straight out. The state of the pleats will tell you the change was due.
3. Slide the new panel in following the airflow direction marked on the housing, seat it fully, and click the cover back on.
4. Raise the glovebox, refit the damper, and run the fan. Fresh media restores full vent output immediately.

• Brand / part: micronAir CF112, in micronAir retail packaging (shown in the photos)
• Media: pleated activated carbon cabin filter media
• Function: dust, pollen and fine-particle filtration + odour and exhaust-gas adsorption
• In the box: 1 × CF112 cabin air filter
• Replacement interval: once a year or every 15,000–20,000 km. City, dusty and high-pollen driving loads the panel faster — if the vents weaken or a stale smell arrives with the airflow, change it early.

What is CF112 — is it a size or a brand?
It is a part code: micronAir's catalogue number for this cabin filter. "CF" is micronAir's cabin filter line and "112" identifies this panel and housing. When a workshop orders a cabin filter for a DOLPHIN or ATTO 3, CF112 is the number they look up — which is why it is in this product's name.

Does one filter really fit both the DOLPHIN and the ATTO 3?
Yes. The two cars share BYD's e-Platform and the same cabin filter housing, so they share the filter. The fitment panel in the photos lists DOLPHIN 2021–present and ATTO 3 2022–present for this single CF112 panel.

Is this the carbon version or the plain paper version?
The carbon version. The media in the photos is the grey activated-carbon type: it filters particles like a standard panel and additionally adsorbs odours, exhaust fumes and volatile compounds. A plain paper filter cannot do the second half of that job.

How often does my DOLPHIN need a new one?
Once a year or every 15,000–20,000 km is the established interval for this filter. Treat the car's behaviour as the final word: weaker vent output, slower demisting or a stale smell when the fan starts all mean the panel is saturated and due, whatever the mileage.

Where is the filter, and can I fit it myself?
Behind the glovebox, in the HVAC housing. Lower the glovebox past its stops, unclip the housing cover, slide the old panel out and the new one in, and refit the cover. It is a few minutes of work with no disassembly beyond the glovebox itself.

My vents smell musty when the air conditioning starts — will this fix it?
Yes, in the most common case that smell is the old filter itself: a saturated panel holds a year of damp dust and organic load, and the first blast of air carries its smell into the cabin. A fresh carbon panel removes the source and adsorbs odours in the incoming air from then on.
