The air quality in the capital has been in very poor condition for the last few days. Especially in the condition of Air Quality Index in Delhi around December 15, it is considered extremely dangerous to leave the house. The AQI situation in Delhi ranges from 400 to 700 at different places. In this situation, it is suggested not to leave the house at all, but this polluted air is entering the house also. In such a situation, to avoid this polluted air in the house, people install air purifiers in their homes and offices. Are these air purifiers really useful? Let us know how they work.
How does Air Purifier work?
How the air purifier will work depends on which filter the company has used in this device. HEPA filters etc. are used in this device, these filters work to improve the quality of air by sucking the smallest particles present in the air.
To explain in simple language, air purifiers suck bad air and the filters installed in the purifier work to eliminate viruses and bacteria. For your information, let us tell you that four types of filters are used in air purifiers, HEPA filter, oil generator filter, carbon filter and UV filter etc.
What will happen if you buy an air purifier without a HEPA filter?
By purchasing an air purifier without a HEPA filter, the device will not be able to trap small particles present in the air, such as dust, smoke, toxic gases, and bacteria. It can transmit toxic or allergy causing particles which can affect your health. Since an air purifier has a HEPA filter, it traps small particles present in the air and purifies the air. Therefore, buying an air purifier without a HEPA filter will not be able to repair poor air quality.
Note these 3 important things
If you are also going to buy an air purifier, then you should first know about three important things like room size, CADR Rating and HEPA Filter. Do you know what CADR is? CADR means Clean Air Delivery Rate, this rating shows how much air the air purifier can clean in an hour. Explained in simple language, the higher this rating is, the more air the air purifier will clean in an hour.
