Whereas, the ULPA (Ultra-Low Penetration Air) filter can trap particles up to 0. For typical respiratory issues, the purifier must filter out PM 2. Once the Plasmacluster block comes in contact with other non-conducive surfaces, they can remove static charge.Predominantly all brand air purifiers come with HEPA filters (an international standard air filter that can trap particulate matter) and four filtration layers, but there are some budget options as well wherein Air Purifier with three filtration layers are available.5) can enter the bloodstream and settle in the lungs, which can lead to cancer of larynx, nasopharynx, lung, and leukaemia, cardiovascular and respiratory illnesses like acute respiratory tract infection and COPD. Electro Static Precipitator (ESP) is another filter that consists of charged wires which trap coarse particles. Ozonizers work much like an ionizing purifier, but it is designed to alter molecules of oxygen and turn them into ozone that breaks down airborne particles.
These masks usually come with N99 & Carbon filters and are priced between Rs 200 to 2000. Negative Ionizers generate negative ions that magnetically attract airborne particles such as pollen and dust until the newly-formed particle is too heavy to remain in the air.5 microns, fine particulate matter (PM 2. As per a 2016 report by WHO, 4 out of 5 most polluted cities of the world are in India, with Delhi being in the 9th position.5 and if exposed for a longer duration may inflict serious health hazards.For outdoor activity use of breathing mask is suggested as they have the capability to trap dust, pollen, toxic gases, PM10 and PM 2.Some purifiers use Active Charcoal as well, which has a layer of carbon particles that can absorb certain gases but the efficiency of this filter depends on the volume of air drawn. Plasma discharge generates and emits the same positive and negative ions that occur in nature. Air purifiers may further help reduce dust, pollen, allergens, particulate matter and odour from the air making it cleaner and more breathable. Measuring less than 2. When choosing an Air Purifier, Clean Air Delivery Rate (CADR) needs to be considered as the higher the CADR, the more air gets purified. Depending upon usage requirement, brand, quality and technology these devices are priced between Rs 5,000 to Rs 90,000. Air Wholesale function submersible pump purifiers using UV Light & PCO technology uses UV light to destroy microorganisms.
