Live in a pollution free environment at home. Get yourself an air purifier to remove impurities and allergens from the air you breathe. This guide will introduce you to the following points:
You need an air purifier for the following reasons:
Dust particles, allergen and bacteria can be present in different shapes and sizes in the air. An air purifier helps catching all of these, thereby reducing the pollutants from the environment. For comparison, here's a table charting the difference in size of various particles:
|Particle||Size (in microns)|
|Tobacco smoke||0.003 – 0.04|
|Bacteria||0.3 - 3|
|Fungi||0.5 - 5|
|Mould||2 - 20|
|Dust mite||10 - 40|
|Plant spores||10 - 70|
|Pet dander||0.3 – 100|
|Pollen||10 - 100|
Ideal for placing on table tops, shelves and in cars.
Air purifiers are also further classified based on the filters they use. Here are a few types:
Your air purifier should be able to monitor dust levels and turn itself on when they hit a certain percentage.
This feature lets you control how quickly you want the air to be cycled. It also lets you control noise levels.
This makes it easy to know when a filter needs replacing.
You can adjust the air purifier from a distance with a remote control. This is especially useful for the elderly and the infirmed.
All air purifiers produce sounds but some are quieter than others. For comparison, normal breathing sounds are at 10 dB while a whisper is 30-40 dB.
A timer feature can let you set when you want the purifier to operate. This saves energy.
This feature comes in handy when you need to clean air quickly. The purifier is run at the maximum speed for a set period before slowing down.
Energy Star-rated air purifiers utilise electricity more efficiently. They can be 40 percent more efficient than non Energy Star-certified products.
With sleep mode on, the air purifier's fan speed is reduced and produces less noise.
Most air purifiers consume about 50W on a low setting and around 200W on high.
