Streamer discharge that decomposes odours rather than trapping them
Our editorial score
Very good — recommended
Long-term owners who would rather clean a filter than keep buying them.
Look at the running cost line: ₹1,800 a year against ₹3,500-6,500 for most rivals. Daikin's electrostatic HEPA is rated for up to a decade provided you actually vacuum and wash it on schedule, and the Streamer discharge breaks down what the filter has captured rather than letting it sit there breeding. Over five years of ownership this is one of the cheapest purifiers here despite the sticker price.
The condition attached matters. Skip the cleaning schedule and you get a clogged filter and mediocre performance. If you are the kind of owner who will follow it, this is a genuinely smart long-term purchase.
Every condition below is derived from this product's published specifications and from how it compares with the air purifiers we track — so you can check each one against your own room, supply or budget rather than take our word for it.
Your room is bigger than about 225 sq ft
It is rated for 450 sq ft, but that assumes roughly one air change an hour. For visible results in Indian winter conditions, halve it — which puts the realistic ceiling near 225 sq ft.
Work out the CADR you need →You need it quiet at the speed that actually works
It reaches 53 dB at its loudest setting. That is fine in a living room and intrusive in a bedroom, and the quiet modes on most purifiers move far less air.
Compare noise across the database →You are trying to remove smells, smoke or gases
No meaningful activated-carbon stage is fitted. HEPA captures particulate and does nothing whatsoever for gases and odours — this is the most common mismatch in the category.
Purifiers with real carbon filtration →You want the HEPA grade stated rather than implied
The brand claims HEPA filtration without naming a grade. H11 and H14 are very different filters, and only 2 of the 13 air purifiers we track name theirs.
See which brands publish a grade →You want to verify it is working rather than trust it
There is no numeric PM2.5 readout. A colour ring cannot tell you the room went from 180 to 22 µg/m³, and it cannot tell you the filter is exhausted.
Strong transparency. This is separate from our review score above — it measures how well documented, how supportable and how expensive to own this air purifier is, scored on 7 of 7 axes by formula, with no manual override. See the methodology.
