Air Purifier helps in Killing Corona virus ???

Is air purifier necessary for a household, does it effectively provide breathable air? All of these questions will be answered here. The system to purify the air is simple just the air needs to pass by the filter to give out good air without PM 2.5. The main layer in a filter to capture PM 2.5 and other harmful particles is the HEPA filter layer. There can be other layers also like Activated carbon filter and a primary filter to remove dust and hair. Other things to note while buying an air purifier that how fast it produces good air to breathe. I am personally using the cheapest air purifier in the market that is Mi air purifier and it has 2 variants one with smart features and one without it. Mi air purifier with smart features costs Rs 9999 and it can be operated from Mi home application which is available for both android and IOS. You just have to connect your device with your wifi at home to stay connected with the internet so that It can be operated from the application on your mobile. You can check the PM 2.5 level and turn on or off. It also works with Google Home and Alexa speakers. It sucks air from 3 sides on the purifier and blows out good air from the top. The speed of producing cleaning air is 380m3/h which is very fast and it is silent also. It also has a night mode to make it ultra silent. For this purifier 2 filters are available one with a dual-layer of primary and HEPA filter and one is with 3 layers, an additional activated carbon filter layer. The main purpose of the air purifier to remove harmful particles from the air and you can feel it when it cleans the air in your room. Also, it doesn’t work for the whole house; it works in a single room with closed doors. If you want to secure your whole house then you have to buy 1 air purifier for every separate room. The air purifier without smart features is the bang for the buck at just Rs 6499 it provides clean air but its speed of production of clean air is less than the expensive one.  It indicates the PM 2.5 level with led indicators, green is good air,   orange is little bad air, red is for extreme bad air. The air purifiers use electricity just equal to a zero watt bulb. Now the question is, do we need it and is it good to buy? It is effective in cleaning the air but it doesn’t need to run all the time. Just turn it on when you need it otherwise doesn’t. Watch the video to know more
