Review: Havells AP-22
The design of the AP-22 is quite compact if you compare it to most similarly priced rivals. Unlike many purifiers that have clean air outlet vents on the sides, this has the more conventional placement on the top—so cleaner air spreads through the room much quicker. The control panel is touch-enabled, with buttons for fan speed, modes, the child-lock, timer and power on/off. The front has an LED indicator that tells you about the current air quality in the room—red for bad, purple for acceptable, and blue for clean air.
The Havells AP-22 has a rated clean air delivery rate (CADR) of 200 m/h, and is capable of cleaning rooms up to 39.76 sq. m in size. Like purifiers from the likes of Philips and Atlanta Healthcare, the AP-22 also has a three-layer filter set-up—a pre-filter, a Hepa filter and an activated carbon filter. In a bedroom, it improved the air quality from a very unhealthy 112g/m to 24g/m in 30 minutes, in the automatic mode that kept altering fan speeds. There are four fan-speed settings, with the lowest and most silent one being the sleep mode. At fan speeds 1 and 2, you won’t even notice the AP-22 working in the background. At the maximum speed, however, the fan does become rather noisy.
Chances are, Havells may not yet be the first name that comes to mind when you are considering an indoor air purifier. The performance, however, is more than satisfactory for most room sizes. The only problem for Havells AP-22 is the more established competition: the Philips AC2887/20 (Rs20,695; 334 m/h CADR), Blue Pure 211 by Blueair (Rs22,990; 590 m/h CADR) and the Honeywell Lite (Rs19,990; 210 m/h CADR), all of which have potentially more powerful indoor air-filtration capabilities.
The Havells AP-22 scores when it comes to the cost of the Hepa filter replacement: Rs2,890. In comparison, the filter for the Honeywell Lite costs Rs4,595 and the Blue Pure 211, Rs7,887—depending on the air quality in your home, you might need to change this Hepa filter at least once anytime between six months and two years.
