Eureka Forbes Aeroguard AP700

When this is not a good choice

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 275 sq ft

  It is rated for 550 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 275 sq ft.

• You need it quiet at the speed that actually works

  It reaches 55 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 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.

• 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.

Transparency Score: 6.3/10

Fair 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.

Specifications are from manufacturer literature and were checked at the last price-verification date. Brands occasionally revise stage counts, tank sizes and warranty terms without changing the model name — confirm against the current listing before purchasing.
