Nowadays, the levels of pollution in the air are increasing every day. The emissions from vehicles and industries reach an all time high. Unfortunately, there isn't much hope for things to be changing for the better in the recent future. Moreover, the buildings we live in are also polluted. These places do not allow air to either leave or come inside. That's why, the impurities already present in the air has no way to get out. No oxygen can flow in from the outside, and the possibility of oxygen cleaning the air is also nullified.
 But there is one way we can use to help us a little. These are air purifiers. And this is the only solution to this problem. Impurities in the air have been linked to several respiration illnesses including asthma. Moreover, it has also been held responsible for problems like sinusitis. Breathing impure air affects the quality of our sleep. That's why, it is very important to have an air purifier at your place.
You can find many air purifiers in the market. They can be differentiated on the basis of the kind of filters it uses.
The ionic air purifiers are very popular. Such air purifiers actually have ionizers inside them. Basically they work on the principle of static electricity. And when switched on, the plates inside the purifier gets electrically charged which subsequently charge the dust and smoke particles. Once they are charged, they will cling on to the neutrally or positively charged surface of the air purifier.
But they have one disadvantage. The heavier particles may actually fall off if two dissimilarly charged small particles clump together.
Nevertheless, the ionic air purifiers come with a pre-filter which actually separate the larger dust particles from the smaller ones. Recently better air purifiers with more advanced filters have been launched. But, if someone in your family doesn't suffer from severe respiration problems, you can well do with an ionic air filter.
