Factors to consider when purchasing an Air Purifier

Now that we have enumerated the best quietest air purifier we have in the market, it’s time that we analyze which one of those would be the perfect fit for you.

In order to help you with that, we have enumerated some factors that you should consider when purchasing your air purifier.

Noise Level

If you’re looking for a quiet air purifier, then this should be the first factor you should consider. A clean environment will be even better if we don’t hear any sound coming from it. This noise usually comes from the motor running and the fan blades rotating. 

The truth is, there’s no silent way to move air. But we can measure the noise level to see what noise level is fine for us. 

Noise level is measured through dB(A) or decibels. A comparison below will show you what kind of noise an air purifier produces at a certain decibel. 

  • Rustling Leaves - 10 dB(A)
  • Very quiet air purifier - 15 dB(A)
  • Whispering - 20 dB(A)
  • Good air purifier on low - 32 dB(A)
  • Typical air purifier on low - 36 dB(A)
  • Fridge - 50 dB(A)
  • Dishwasher - 55 - 70 dB(A)
  • Vacuum Cleaner - 80 dB(A)
  • Lawnmower - 90 dB(A)

Based on the comparison, you can now assess at what level of noise would you be able to tolerate. By knowing this information, you’ll be sure to narrow down your choices easily.

Room Size

Ask yourself, how much space do you want to cover? As you see, the air purifier coverage can range from 90ft to 1100 ft depending on the model you choose. 

Most of the time, the larger the air purifier, the larger the coverage is. But it’s still better to make sure by checking the information on how big it can actually cover. 

Buying a wrong model of air purifier based on your room size will be useless as it won’t be able to filter out all the pollutants. In addition, figuring out how big your space is will narrow down your options.

Type of Filters

Not all air purifiers are designed with the same types of filters. Some come with 6 layers while others come with 3 layers. There are even those that can be customized on your needs. 

The most common and nice-to-have filters are the True HEPA filter that aims to trap and eliminate the air pollutants, and the Carbon Filter that is designed to eliminate unpleasant odors.

There are also filters designed mainly to remove pet allergens, PlasmaWave, and so on depending on the brand and model of the air purifier. 

So it’s also best if you know what types of air pollutants you really want to target and look for an air purifier that comes with a filter that targets that.

Fan Speeds 

The more the fan speeds, the more control you actually have in your air purifier. This feature is actually nice to have because it’s pretty convenient.

If you want to clean the air surrounding you faster, you can just adjust the fan to its highest speed to quickly remove air pollutants.

Budget

The Budget is another important factor. How much are you willing to spend for an air purifier? 

The prices can range from $100 to $1000 depending on the brand, model, quality, and features. So if budget is something that is your concern, then you should check the pricing of the air purifier as well. 

There are a lot of good quality air purifiers even in the middle range budget that also come with a lot of nice features.

Features

Features are also really nice to have. These are usually brought by technological advancements or improvements made by the manufacturers. 

Some nice-to-have features are the auto-function feature, the timer function, the air quality indicator, the filter replacement indicator, a remote control, and a lot more.

These are not only nice features but can also give a lot of convenience to you.
