Features That Make A Good Air Purifier

1) Why Are You Buying An Air Purifier?

Buying An Air Purifier

As it always happens, there is not the perfect air purifier or the absolute best one.

It all depends on your needs because if you want to remove allergens from the air, you’ll need a certain type of air purifier; if you need to remove smells, you can buy a different option.

So, the first thing you should consider is why you are buying an air purifier? Do you suffer from asthma or some kind of allergy?

Perhaps you live just next to a restaurant’s kitchen and are sick of its smells? Or do you live in a polluted capital city? For each of these problems, there is a different solution.

2) Type Of Filter

Type Of Filter

What determines if an air purifier can remove allergens or only smells? of course, it all depends on the filters.

So, the second thing to consider is, of course, the type of filter:

  • HEPA filters can capture more than 99% of particles as little as 0.3 microns. They are considered the most effective, but they are the most expensive
  • Carbon filters: on the contrary, these filters are the cheapest, but they are only effective in removing smells
  • UV filters: they are the most effective if your aim is to remove pathogens from the air (bacteria, viruses, or spores) because they kill them.
  • Combined solution: even more effective than HEPA filters are combined solutions: air purifiers that use more than one level of purification using two or more different technologies, for example, HEPA filters + UV lamps or HEPA filters + carbon filters. 1

3) Design

You’ll hardly hide your purifier inside the room. Especially if it’s an office or a living room, and everybody is going to see it, you want to pick a design that matches your furniture.

4) Noise Level

Noise Level

In this case, you need to check the dB rating. Of course, you want your air purifier to be as quiet as possible.

The quietest air purifiers on the market will have a dB rating of 20-40 at the lowest fan speed, while the loudest ones will be rated 50 to 70 dB and above.

5) Energy Consumption

The last thing you need to consider is energy consumption. The best air purifier would be energy efficient.
