Air purifiers are becoming an essential part of our lives. They make our air clean and free of pollutants, while also keeping the inside air fresh.

However, there’s a flood of options out there at the moment. And choosing the right air purifier can be a challenge. First of all, you have to choose between what filtering media the purifier uses. Most of them use HEPA filters or activated carbon filters. Though, you do find many purifiers that use ionizers or UV lights to get rid of microbes.

There’s a couple of things to consider before we head onto the list, though. Take a look at some of these factors that will allow you to make a better decision.

  • How big of an area you want to cover with the purifier?
  • How much you are willing to spend on one?
  • What type of filtration do you prefer to use?
  • What size do you want the purifier to be?
  • Do you prefer power over silence, or are you looking for a mix of both?

Without further a-do, let’s dive into the list.

1. Coway Airmega 300 Smart Air Purifier

In addition, it clears 99% of all organic compounds and chemicals, such as NH3 and CH3CHO. This makes it a great option for areas where the pollution is very high.

The True HEPA filter is combined with the activated carbon filter, and they make a combination – together, they form the Max2 filter, which takes care of air purification as well as odors and weird smells. This filter can be removed as a complete entity, and you’ll need to purchase one after a few months.

The pre-filter that’s located prior to the Max2 filter is permanent and washable, meaning that you’ll be able to use it again after some time; wash it, and re-use it. This filter will remove the larger particles from the air.

This device also features a few smart design options. There are five fan modes, letting you choose between Smart, Sleep, Low, Medium, and High. The lower speeds are aimed for silence, while the higher speeds are better for performance.
