Ionisers clean up your air and save your lungs and skin from damage.
Keep an ioniser switched on wherever you spend time, - in your office, in every room in your home in which you spend time, and in your car.
Ionisers improve the quality of the air, making it safe by generating large numbers of negative ions, which combine with the positively charged particles of dust, smoke, bacteria, viruses and fungal spores, causing them to settle down. Charged particles called ions, repel each other when they come close to each other, thus staying in motion because of a phenomenon called Brownian motion. Electrons are examples of negatively charged particles. Dust, smoke, bacteria viruses, mold, pollen etc are examples of positively charged ions. When a positively charged particle comes into contact with a negatively charged particle the charge on both particles is neutralized and the particle sinks to the ground. This settling down of the particles improves the air quality helping the sinuses to heal.
Use an ioniser wherever you have pollution, air conditioning or central heating. Always install an ioniser in your car as heavy traffic has high levels of pollution. If you live in a polluted city use an ioniser in every room in which you spend time. A good ioniser should generate at least a trillion ions a second. Ionisers available in the market generate between 1500 ions per second to 45 trillion ions per second. Ionisers with a light and Himalayan salt usually generate 1500 ions per second and are inadequate in highly polluted areas. An ioniser which generates a trillion ions a second can reduce the particle count in a room with a cubic capacity of 3000 cubic feet (300 square feet with a height of 10 feet) (84 Cubic Meters) by 99.98 percent in 1 hour. Keep your ionisers on all the time so air quality in the room is good whenever you enter it. Ionisers use between 3 to 15 watts per hour, so running costs are negligible. Ion concentrations reduce with the square of the distance from the ioniser. So if your area is larger than 3000 cubic feet, 2 ionisers will be more effective than 1 large ioniser. The price of a good ionizer begins around Rs 3000.
Place the ioniser a distance of about 3 feet from where you sleep. Ionisers cause the suspended particles to settle down so the area around an ioniser turns black. To prevent this dirt from spoiling your walls or furniture place the ioniser on the floor or on an easily cleanable surface like a glass or stone table. Placing electrostatic paper behind the ionizer also helps to trap the dust. This paper can then be changed every few months. Some ionisers contain a filter to trap the dust. These filters are HEPA filters which have to be replaced periodically. Often the replacement cost of the filter can exceed the cost of the ioniser over a period of a year! This makes ionisers with a filter unviable in heavily polluted areas. Spend 5 minutes to clean and maintain your ioniser every week as advised in the instruction manual of your ioniser to ensure that it keeps giving you the full benefit.
