Features to look for in an air purifier:
- Technologies used in air purifiers
There are five common techniques used for filtration in air purifiers. The most famous and effective technology is HEPA which stands for High-Efficiency Particulate Air. This removes impurity particles bigger than 0.3 microns but cannot remove foul odour.
The activated carbon technology is used to absorb allergens and contaminants. It also absorbs harmful gases like formaldehyde and foul odour. UV technology or ultraviolet technology is generally used in the final stage of the air purification process.
In this process, there is a UV lamp which destroys the microorganisms present in the air. The byproducts produced are ozone and hydroxyl. In negative ion technology, the ions magnetically attract particles like pollen and dust which gets accumulated together.
This heavy accumulation then attaches itself to another solid item like a window or wall. This method is ineffective as it does not get rid of the pollutants entirely. Ozone technology pumps ozone into the air which in turn oxidises and kills mould and mildew and gets rid of foul odour.
This technique is not preferred as it leads to certain health issues. In addition to these, most of the air purifiers use a combination of more than one technology to achieve effective filtration.
- ACH Ratings (Air change per hour)
ACH rating is used to convey information about how often the air purifier can change the air in the room. It is expressed as 3x,6x, etc. in multiples of ‘x’. It is advised to choose the one with the highest number as this will clean the air faster.
Air purifiers can be used for different needs. It can be used to improve the air quality for family members with allergies, asthma or hypersensitivity to chemicals. It can also be used to protect your family members from being susceptible to such health conditions.
- Size of the room
Every air cleaner has a certain capacity or coverage area. This determines the effective usage of the appliance. If the size of the room is bigger than the coverage area of the air purifier, the cleaning would not be efficient and the sole purpose is lost.
Depending on the technology used in the air purifier, they can only filter a particular type of impurity. While choosing an air purifier, make sure to check if the particles they can filter matches with your needs. Air purifiers can be used in bedroom, living room or even in a car.
As with any electronic device, air purifiers demand regular maintenance to perform their best. This includes the change of filters and cleaning it at regular intervals. You must also keep an eye on the warranty period and the after-sales maintenance service.
Air purifiers are no more a luxury product. Owing to the alarming rate of increase in air pollution around the world, it is now a necessity to own an air purifier to control the quality of air you breathe inside your house or office.
Many companies are coming up with an affordable range of air purifiers with latest features due to this reason. It is wise to make an informed decision as choosing the right air purifier could determine the health of your family members.
