Tips for Choosing the Best Air Purifier

I’m sure you will agree with me when I say:

Choosing the best air purifier for your household or office is a daunting task.

Purchasing it is a one-time investment and can go terribly wrong if you do not know what to look for. Do not get confused by the sales jargon and look out for these seven important things before you make your choice:

Understand Air Cleaning Technologies:

Today, there is no single air purifying technology. That is why manufacturers often club different technologies together for the best results. E.g. HEPA filters are good for getting rid of micro particles, but do nothing for bad odors. In this case, it is very important that you understand the different technologies and choose a product that provides you with multiple results.

Size Of  The Room:

Air purifiers work over a certain area. Make sure you buy an air purifier that is capable of covering the area that is slightly bigger than the area you will install it in.

CADR – Clean Air Delivery Rate:

This rate is a scale of how efficient the air purifier is in reducing pollen particles, smoke and dust. The higher the CADR, the faster is the speed of the purifier.


Cost is one of the most important factors. Compare the cost of different purifiers online as well as offline. Apart from the purchase cost, you also need to keep in mind the cost of maintaining the purifier by changing its filters. Also, keep in mind you will need electricity to run the cleaner, adding to the cost.


Apart from the replacement of the filter, certain purifiers require monthly cleaning by hand. If you do not want to increase your chores, you may want to invest in a maintenance free unit.


Air purifiers are not noise free – rather, some sir purifiers are extremely loud! The faster the fan speed, the louder the noise it will make.

Your Needs:

Along with purifying function, you need to keep in mind the space the purifier will occupy and the aesthetic it will add to your room. That said, don’t invest in a fancy-looking air purifier that doesn’t do its job efficiently!

So, here you have it, 7 things you should keep in mind while buying an air purifier!
