pollen, spore, pet hair, smoke, and even bad smells from room. However, it does not use any types of filters or ionizers to purify air. Instead, it uses a water filtration to trap in all the allergens inside room. Most water-based air purifiers use a rotating motor to create water swirls. Here, allergens are trapped, and the water continuously cycles inside the water reservoir. As a result, the machine can also function as a versatile humidifier and a scent diffuser.
development in cities, contributing to extreme air contamination in the inside. As a result of these developments, greater attention has been paid to the problem of safe and balanced indoor environments. To enhance the indoor air quality, various air purifying techniques were adopted. Air filtration technique can eliminate air contaminants and effectively reduce worsening air quality indoors the system makes use of blower which sucks the air. When air is passed through a water tank situated at the bottom of the purifier. The air passed through water gets purified as water traps dust, fungi, bacteria etc... In the water. The resulting air rising through the water is a purified air. Also added essential oils to the system allow for humidifying the area/room with essential oils which helps humans to relax. This project finds its application in various places like in IT industries, colleges and schools, clinics and medicals, Bakery factory, high population cities Where air is polluted due to large number of vehicle travels and industries The people living in metro cities may get effects on their skin, age and their organs. By using our waterbased air purifier the affects may get decrease to some extent.

Despite this, water-based air purifiers are preferred for their multifunctional use at a reasonable price. Although they cannot clean air at a microscopic well, they are excellent for purifying air from most allergens. Hyeon-Ju Oh et al. [6] investigated the indoor air quality and efficiency of air purifier in childcare centers and found enhanced efficiency of air purifier. Shiue et al. [7] reported the particles removal by negative ionic air purifier in cleanroom. This study investigated the effect of particles at various locations like heights and distances with reference to the source of negative ions. The results of experiments around the negative ionic purifier showed better performance compared to the rest of the cleanroom. With reference to height, it was observed that at 60 cm, highest removal efficiency was recorded. This height was measured from floor. It was also observed that this efficiency reduced substantially with increase in height. Hye-Kyung Park et al. [8] reported air purifier and its effectiveness on health outcomes of children with allergic diseases and indoor particles. The living rooms and bedrooms were installed with an air purifier amongst the active group for the test period of 12 weeks. For the week 0, 6 and 12, asthma control test, peak flow rate and nasal symptom scores were evaluated. An improvement trend in asthma control test and peak flow rate was observed in the active group compared to control group. On the other hand, the control group showed deterioration. Yoshiko Yoda et al. [9] investigated air purifier and its effects on indoor environment and respiratory system of healthy human beings. The results revelled that enhanced air purification in ordinary homes but it did not show any improvement in the health.

1. INTRODUCTION Air cleaners and filters can help reduce airborne contaminants including viruses in a building or small space. The peoples living in an apartment, it is highly likely that they are exposed to higher concentration of pollutants due to smaller living space. Also, people in apartments cannot control the behaviour of neighbours who might be smokers, using firewood in winters, not cleaning homes regularly and thus, exposing to odour and smoke. By development of air purifier which does not use expensive filters but rather uses water. Also it acts as an air humidifier and can be used as oil diffuser too which helps to relax and also kills certain bacteria and viruses present in the air. Air purifiers use blower to suck the outside air. Then air is passed through water. A water-based air purifier or water-
