Kent Aura air purifier review: low airflow for the money and a spec sheet that contradicts itself

How we researched this

We have not used this purifier. We read Kent’s product page, the Flipkart listing, its owner reviews and the filter kit listing on 12 November 2026. We could confirm the price, Kent’s CADR, power and filter-kit price. The sources disagree on CADR, coverage and size, and neither publishes filter life, a noise curve or an ozone figure. We have not measured airflow or noise.

Airflow is the problem

Clean air delivery rate (CADR) is the number that decides how fast a purifier cleans a room. Kent lists 183 m³/h for rooms up to 270 sq ft. For about the same money, Philips lists 250 m³/h for the AC0920 and Xiaomi lists 360 m³/h for the Smart Air Purifier 4 Lite. Unless the Aura does something special, it moves less air for the money.

Filtration and features

Kent describes three stages: a primary filter for large particles, an activated carbon filter for odours and gases, and an antibacterial-coated HEPA filter. It does not state the HEPA grade (H13, for example). There is a built-in ionizer, an air-quality sensor with an on-unit display, a filter-change indicator and a child lock. Kent does not say whether the ionizer produces ozone.

Spec sheet problems

Flipkart’s table lists a CADR of 180 m³/h, while its key-features line says 250 m³/h for rooms up to 250 sq ft. Kent lists 410 x 242 x 580 mm; Flipkart lists 35 x 48.2 x 18 cm and a pink colour. Flipkart’s description also says the unit “operates silently”, while its spec table lists 60 dB. We use Kent’s own numbers, but the inconsistencies don’t inspire confidence.

Running costs and warranty

Kent’s filter replacement kit for the Aura costs ₹3,500 on Flipkart. Kent does not say how long a set lasts. The Flipkart listing gives a 1-year warranty for manufacturing defects only, with carry-in service at a service centre.

What owners report

Flipkart shows 3.9 stars from 1,084 ratings: 545 five-star and 134 one-star (about 12%). The review pool is unreliable. Some reviews date back to 2018, some are for a 400 m³/h variant, and several recent one-star reviews complain about water leaking, which an air purifier should not do, so they almost certainly belong to a different product. The one-star review tagged with this model’s 180 m³/h, pink listing describes a button that stopped working and a unit that kept stopping in auto mode from day one.

Should you buy it?

We would not, at ₹9,300. The Aura’s published airflow is well below rivals at the same price, its listings contradict each other, and its filter kit is expensive. Buy it only if you can get it at a steep discount for a small room. Our score is provisional until we test it.
