Frequently Asked Questions
The salient factors must be taken into account before you make the purchase of the best air purifier in India.

7. Number of Filters
8. Child Lock
It is the most ideal to place the air purifier in the room you must spend time in. It is an incorrect notion to place it in the room which gets air ventilation most. Air purifiers are for your benefit, so place them in the room you spend most or in the bedroom if you suffer from respiratory distress.
It is ideal to run it the entire time you are occupying the room it is in. The modes and fan speed must be altered as per the change in air quality and the noise tolerance levels. But switching on and off the air purifier is discouraged.
While we have provided the noise of every air purifier brand in decibel values, in real sense it is not very loud. The noise gets amplified at the highest fan speed, but that depends on the noise tolerance level of self.
While the CADR for different models differ from the other, the rate at which air is purified is dependent on the Clean Air Delivery Rate. So one air purifier with a higher rating cleans it faster and vice versa. Having said that, on an average, it can take anytime between 15-30 mins.
Air purifiers are fast becoming more important than earlier. With rising pollution levels, clean air is becoming the need of the hour to fight acute respiratory conditions arising from polluted air.
