Before buying read alot of reviews alot of them were positive and some of them were negative,had alot of doubtes should i buy it or not ,but eventually i bought it,and im very happy with it,i never had devices for objective controls the ionic composition of air ,but after turning on the ionizer a while the air in the room became softer or something ,I cant even to explain it,but feels very fresh when u move from one room to another ,at the beginning it felt like the windows are always open ,but later i relalized that the windows were closed and the effect of freshness were not given by the outside air but by the ionizer,its main function is why it dose not turn off it couse cleans the air -this is air purifier .
in fall and spring our city covers in smog from burning fields ,its extremely hard to breath on the street ,And if you accidentally forgot to close the windows,you will end up with smoke in your room ,The ionizer copes with this error at full power in only 5 minutes ,We have around 300 sq ft room after we transfer to average power mode and that how we are using it ,
Another example : we dont have a hood in the kitchen ,when had to fry food ,later we had to ventilate the apartment before,now its only enough just to put an ionizer on ,he copes with smells faster than if the doors in the next room were open for plowing ,im not exaggerating , I don't understand how it works ,but it dose
