Many users wonder why the Xiaomi Smart Air Purifier 4 Lite is not making a difference in reducing the AQI (Air Quality Index). It’s widely understood that the AQI is directly relevant to the removal of viruses and germs from the air. Well, it is not. AQI measurement and virus removal are two different aspects of an air purifier. So, if the purifier is cleaning the air, AQI won’t decrease due to many reasons.
It invokes many questions in the user's mind. You can easily doubt the efficiency of the air purifier. When it claims to remove 97.99% of germs and viruses, it is odd to see AQI meter is showing the red signal. Hence, all the doubts will be cleared in the discussion below. Hence, Xiaomi Air Purifier 4 Lite is leading in providing clean, fresh air to the people of Pakistan. And they chose Xiaomisale to buy Xiaomi air purifiers because it offers the best price.
Why Smart Air Purifier 4 Lite not reducing AQI?
Before diving into the debate, why the Air Purifier 4 Lite is not reducing AQI, let's understand the term. This measures the air quality around you. Poor air quality includes cigarette smoke, fumes, cooking particles, garbage burning, outdoor smog, and traffic smoke. These traces are called PM2.5, are invisible to the naked eye and are completely different from biological viruses and bacteria.
There could be many reasons your Smart Air Purifier 4 Lite is not reducing AQI. Which surely isn’t that they aren't working efficiently. Let’s unfold them below:
- AQI shows real-time air quality, not the filter efficiency. So, if the current air is polluted and you just turned it on, you are going to have a high AQI number.
- It won’t improve air quality instantly; the purifier will take time to achieve complete air circulation.
- If the room is larger than the purifier's capacity, it won't drop the AQI drastically. It will take more time than you expect.
- The AQI will be shown under the high range when there is a constant source of PM2.5 coming inside the room. This could be the reason your air purifier is stuck at 300 AQI.
- Another reason can be the clogged filters. You need to clean the filters to get the AQI level back to normal.
PM2.5 particles are solid and liquid droplets that are suspended in the air for hours. They can travel indoors easily. You also have many sources of their origin within the home. Cooking smoke or burning can make them linger in the air. They don’t settle naturally as well. Therefore, Xiaomi Air Purifiers 4 Lite takes time to remove them from the surroundings.
However, these Air purifiers are an essential product in every Pakistani home now. Due to hazardous chemical fusion in the environment, the air has become dangerously polluted. So, people are increasingly investing in air purifiers. You can get them from Xiaomisale, an official online reseller of the original Xiaomi products that offers complete one-year warranty coverage.
How does Xiaomi Air Purifier calculate the AQI level?
Xiaomi air purifiers have advanced sensor lasers installed. They can efficiently detect those PM2.5 particles, dust, smoke, and allergens that are invisible to the naked eye. The air flows through these sensors that scatter and hit them to detect. This way, the purifier counts and measures the size of the particles.
This data is converted into the AQI number and shown in three different colours:
- Green for Clean Air
- Yellow for Moderate Air Quality
- Red for Polluted Air
It is the real-time update by the purifiers. If, after a specific time, your closed space is introduced from the air outside, the purifier will turn its green color to red. It shows that the air gets polluted by the particles outside. Moreover, when there is constant incoming of the outer air, the Air purifier could get stuck at 300 AQI, because it is exceeding its capacity of cleaning and shows a high volume of pollutants.
Turning your air purifier on and off to change the AQI number is not the solution, as it's not a device malfunction. Restarting the device won't change the source of the pollution. You need to cut down the source of the pollutants and give the device some time to filter the air.

Final Words
If your AQI is stuck at 300, this isn’t a device fault. The Xiaomi Smart Air purifier 4 Lite is built to provide real-time air quality metrics. If, on consistent use, the AQI is high, then you must check the source of incoming outer air. Moreover, the filters can be clogged. Even if it removes 97.99 per cent of viruses and bacteria, it can still show a high AQI number because it counts PM2.5 particles to show the quality of the air.
