Types of Air Purifiers (Air Purifier Filtration Technology)
- HEPA Filteration –HEPA which stands for High-Efficiency Particulate Air. It is capable of capturing 99.9% of air pollutants such as bacteria, viruses, bacteria as well as toxins. It will also remove H1N1 viruses. The only constraint of HEPA, it does not remove foul odours. You need a carbon activated filter along with HEPA to remove odours.
- Activated Carbon Filteration. – It is made of porous material & absorbs allergens as well as odours. It eliminates VOC’s, harmful gases, chemical toxins, tobacco smoke and also odours.
- UV (Ultra Violet) Filteration. – It has a UV lamp through which microorganisms passes and get destroyed. It also removes airborne particles. Its power depends on the wattage of the UV light and its duration of exposure.
- Ionic Air Purifier: This is the modern way of purifying Air. It captures ultra-fine particles of size up to 0.01 microns. Here it passes a source of negatively charged ions through an ionic generator. Where they attract airborne dust, allergens and other debris. This process will continue until the airborne particle become heavy enough and fall on the floor. Later you can sweep or vacuum them to clean the floor. You can wash them so no need to replace the filters frequently. These purifiers are quite affordable but generate ozone as a byproduct.
- Ozone Air Purifier. – Ozone protects the earth atmosphere from the harmful Ultraviolet Rays from the Sun. While on home an Ozone air purifier kills the mould and removes the bad odour. But ozone oxidises anything in contact. So it is a danger for our small indoor animals as well as it rusts the iron. Ozone purifiers are ideal only for emergency purposes or for commercial reasons.
