Air purifiers have become a necessity for many Indian households, especially in the Delhi National Capital Territory where air pollution levels often reach dangerous levels. These devices filter harmful pollutants, allergens and irritants to help improve indoor air quality and relieve respiratory illness and allergy symptoms.
Kuba Smart air purifiers have recently been launched to address the growing pollution problem, especially in northern India. Priced at Rs 14,990, Qubo Q600 Facing serious air quality challenges, especially in winter, factors such as straw burning, vehicle emissions and industrial activities lead to thick smog.
we used Qubo Q600 smart air purifier Testing its effectiveness during pollution spikes in the National Capital Region of Delhi, here’s what we found.
Qubo Q600 smart air purifier design
Qubo Q600 smart air purifier adopts a simple design and a checkered chassis. The outer shell is made of high-quality plastic and has a cylindrical filter inside. There are perforations on both sides of the casing, through which the purifier can not only suck in dirty air, but also give the purifier a unique appearance.

There’s a grille-covered opening at the top that lets purified air out, and an LED panel with a bunch of touch controls for managing airflow, speed, and other functions. The color display panel shows the level of PM2.5 particulate matter.
Qubo Q600 smart air purifier performance and APP
Setting up the Qubo Q600 smart air purifier is very easy. We simply remove the filter from the back panel, remove the polyethylene and push it back into the chamber before inserting it. You can plug it in and use it, or download an app for finer control.
Notably, the LED panel also provides key controls such as the display, power button, speed setting, auto mode, and QSense AI mode. The front panel displays instant AQI levels and is color-coded (green, orange and red) to indicate the severity of indoor air pollution.
Most of the time, the Qubo Q600 Smart Air Purifier produced PM2.5 readings between 150 and 170 in our approximately 11×15 sq. ft. bedroom (plus a 6×6.3 sq. ft. dressing area). During peak pollution periods, the purifier showed PM2.5 readings as high as 435.

We can choose different speeds – night, 1, 2 and 3 and automatic. In night mode, the purifier operates noiselessly, but it takes a relatively long time to purify the air. We mainly use the machine in automatic mode.
When it is higher than 150, the purifier runs at the highest speed and the fan noise is very loud. For example, when the reading approaches 250, it runs at full speed until PM2.5 levels drop to 150.


When the AQI level exceeds 250, Q600 quickly reduces the PM2.5 level to around 25-30 within 15-18 minutes. When the reading is close to 150-170, Qubo Q600 smart air purifier will complete the purification in 8-10 minutes. On a nice day, we got a reading of 9 PM (PM 2.5) — the cleanest reading we saw during our review. Air purifiers can also quickly remove the smelly smoke emitted after we blow out candles.

In addition to the automatic mode and fan speed, there is also a QSense AI mode that intelligently switches off the device when air quality is good and switches it on when pollution levels rise. There is also a countdown mode that allows us to set a timer (1 hour, 2 hours, 4 hours and 8 hours), after which the device will automatically turn off.

All of these features are also available on the app, but it also comes with useful features like daily, weekly, monthly and yearly insights; filter life, the ability to turn off the purifier over the phone and even automation. The purifier can also be controlled via voice (Google Assistant or Amazon Alexa) and comes with a child lock for added safety in homes with young children.
