Ease Room Air Purifier

Details

An air purifier judged on the only number that matters, clean air delivery rate, published per variant and matched honestly to a room size at two air changes an hour. Three physical stages: a washable metal pre filter, an H13 grade pleated filter, and 900 grams of activated carbon for the smoke and paint smells that a thin carbon mat cannot hold. There is no ioniser and no ozone generating stage, which is a deliberate omission rather than a cost saving. A PM2.5 laser sensor drives the fan automatically and the reading is shown as a number, not a colour.

• CADR published per variant, 250, 400 and 600 m3/hr, with the honest room size at two air changes an hour
• 22 dB(A) on sleep mode and 52 dB(A) on turbo, both at one metre
• Metal pre filter washes under a tap, so the expensive filter lasts longer
• 900 g of activated carbon, weighed and stated, not a coated sheet
• Filter set costs about Rs 2200 and lasts 10 to 14 months in typical urban air, with life tracked by run hours not a calendar
• Spares held 7 years, service manual and part prices published
• 2 years comprehensive, 5 years separately on the fan motor
• Left out: no ioniser, no ozone stage, no UV lamp, no proprietary filter chip, no colour ring standing in for a number
