0.01smaller than most viruses
Delhi's air quality conversation is all about PM 2.5, but the particles that reach deepest into the lungs are far smaller than that — and most filters are rated only to 2.5 or 0.3 microns. Coway's Green True HEPA layer captures ultrafine particulate all the way down to PM 0.01, which is smaller than most viruses and bacteria. In practice that covers the full range: PM 10 and 2.5 from traffic and construction, and the PM 0.1 and 0.01 fractions that pass straight through ordinary filtration — along with dust, pollen, pet dander, mould spores and allergens. For a household with an asthma sufferer, a young child or an elderly parent, that lower bound is the specification that matters.
Max2 — one filter doing two entirely different jobs
A HEPA filter physically traps particles, and smells and gases are not particles — they pass straight through. That's why a purifier can clear the dust from a room and still leave it smelling of last night's cooking. The Max2 solves it in a single unit: Green True HEPA handles the particulate, and a high-efficiency activated carbon layer adsorbs what HEPA can't — cooking smells, cigarette smoke, pet odours, VOCs off paint and furniture, and harmful fumes including ammonia and acetaldehyde, with around 99% reduction. Combining both into one cartridge also means one part number to remember, one item to order, and one component to slide in when it's due.
Genuine Coway — and why the copies cost you more
Third-party filters for Airmega units are widely sold and tempting on price, but an air purifier is a matched system: airflow, fan load and filtration are engineered around the exact filter the machine was designed for. A copy that fits physically can still restrict airflow, reduce the effective clean air delivery, make the fan work harder and noisier, and fall well short of the filtration it claims — and unlike a blocked drain, you can't see it failing. It may also invalidate your warranty. This is the genuine Coway AP-1720-FP, built to hold the purifier's rated performance.

Set a calendar reminder for twelve months from the day you fit it. A purifier running on a spent filter looks and sounds exactly like one running properly — the only difference is that it has quietly stopped working, and nothing tells you.
Roughly a year of use, though heavier pollution or continuous running will shorten it. In a Delhi winter with the purifier working hard, expect to be at the earlier end of that range.
Rated coverage for medium to large rooms — a full drawing room, a large bedroom, or an open-plan living and dining space.
Because HEPA and carbon are combined in one cartridge, replacement is a single component and a single step — no separate pre-filter and carbon layers to order and stack correctly.
