As a result, it never recognises AQI in India to be acceptable. In the week and a half that I've used it, the app has never shown me acceptable AQI levels, settling to average at best.ĭyson says this is because the app matches data with international standards. That's not to say it's not useful or easy to use, it's just set to higher standards than those prevalent in India. The Dyson Link app is new in India and it's the most confusing bit about this device. The Dyson Link app allows remote access, AQI monitoring and more. In contrast, the Honeywell Airtouch S8 has three filters, priced at Rs 1395, Rs 3595 and Rs 2995. After running for about 8 hours a day for a week and a half, my unit says the filters will last for another 4159 hours (about 6 months).ĭyson sells the filter for Rs 2700, meaning it's cheap enough to maintain. It's lab tested for 12 months usage but could last you anywhere between eight to 12 months depending on your usage. The purifier uses a 360-degree glass HEPA filter that can be changed manually when required. That's the speed the Cool Link will choose whenever you set it to Auto, and it will kick into high gear in the next 15 minutes if required. The air intensity can be toggled between one to 10 and the company says four is the economy speed. On regular use, the purifier will kick into high gear intermittently. You won't feel this happen unless you're actually blowing smoke or other pollutants in your room. In practice, there's a sensor lag of about 15 minutes, in which all of this calculations are done. The sensors on Cool Link measure the air quality in your room, send it to the company's cloud servers and turn up the fan intensity. Essentially, the Cool Link will take care of dust, invisible pollutants and odours, just like most other purifiers. VOCs can be produced by paint varnishes, air fresheners, smoking and more. It has two sensors that analyse, PM2.5, PM10 and VOCs (Volatile Organic Compounds). From there, it can oscillate to blow air out in all directions. The Cool Link should be kept in a corner of the room.



Since bringing the Cool Link into the room, there's been noticeably lesser dust on my furniture too. That is, in test conditions, when I was intentionally burning matches etc. In a 20x20 room, the purifier cleans the air in less than 20 minutes. However, it is actually too powerful for most regular rooms. Using the Dyson Pure Cool Link TowerĪ Dyson engineer told me that the company recommends the Tower for most homes. The Dyson Pure Cool Link is meant to be placed in a corner of the room.
