It was the day after Diwali 2019 in Gurgaon. Because we Indians cannot celebrate festivals without polluting at least 1 element of nature, the AQI was 1999. I already had air purifiers (Different makes) in all the bedrooms, but it was getting difficult to breathe so we decided to get one for the living room.
We had had a very good experience with the Xiaomi 2S, so we decided to get another one for the living room. Headed out to Ambience Mall (I miss you so much) and went straight to the Xiaomi store. We had already decided what to buy, so I asked the sales guy to bill one for us. Instead, he laughed at us and said “Stock hi nahi hai to kaha se du”. (We don’t have stock where do I give it from?). Angry at his rudeness, we decided to get the Dyson TP03 (Also known as Dyson Pure Cool Link) instead. Surely, compared to the Xiaomi (₹7999) the Dyson (₹29999) would surely be much better? How wrong we were.
Here’re my views after using it for >1 year
+ Is Stylish, looks nice in the living room
+ Setup is easy and app is very nice
+ App can show historical AQI data
– Can only show AQI on a scale from 1-10 (Both the tiny display & the app). No other details
– Is noisy
– Doesn’t really purify very well or fast. On most days, it couldn’t keep up with outside air leaking in
– Since it throws air straight at the user rather than up in the air, in winters it becomes uncomfortable
At the end of the day, I think the company’s Air Multiplier technology is not really suitable for air purifiers. Basically, if the fan draws “X” amount of air from the pedestal (and via the HEPA filter), it draws 15*X amount of air from the back of the air multiplier which doesn’t pass the filter at all. So at any point of time, only 6.66% of air thrown by the purifier is clean/has passed through the filter, compared to 100% for traditional purifiers.
All of this results in a lot of air flow in the (already very cold) room but very little purification. My impression of all this is that Dyson has over-engineered its purifiers for the simple purpose of purifying air. I feel terribly guilty for not buying 2 Xiaomi purifiers for the same price as this and still have cash left over.
