How to judge the quality of air purifiers (comparison through actual examples)

How to judge the quality of an air purifier?

Many people may have questions. The air purifiers on the market are of varying quality and are available at all prices. How can I judge the quality of an air purifier? In fact, I wrote a related article a long time ago, teaching you how to judge the quality of air purifiers 👉Important indicators for judging air purifiers

Now let's briefly review the indicators for judging air purifiers.

1. CADR: Determine whether the room is suitable for you based on the CADR value👉Calculate the CADR value of the air purifier suitable for your room size

2. Air Purifier Filter: Different filter elements will lead to different purification efficiencies

These are the most core indicators of air purifiers. In addition to these parameters, the remaining parameters need to be determined according to needs.

Critical Parameter Comparison

I took a few machines sold by Coway in Vietnam for actual comparison👉Coway Vietnam sales website

It is not difficult to see that Berk's D3S has a clear advantage in parameters (marked out). Next, I will explain the importance of each parameter one by one.

Why are parameters so important?

Parameter explanation (taking Berk-D3S as an example)

• Particle CADR：Particulate CADR is the most direct parameter related to purification, and the purification of air purifiers has the most direct relationship with it.

• Formaldehyde CADR：
  

  1.Formaldehyde CADR mainly affects the efficiency of purifying some gaseous pollutants, such as smoke, pet odors and other irritating gases. Many air purifiers do not have this function, so they generally do not mark this parameter.
  

  2.Berk's air purifiers have a patented technology specifically for removing formaldehyde, which makes us stand out in the direction of removing odors.
  

• Multi-Sensor Tracking：Sensors can monitor the surrounding environment and let you better understand the surrounding air quality.

• Sanitization Tech：Different disinfection techniques help kill viruses and bacteria👉How UV Lights in Air Purifiers Can Prevent the Flu

• Wellness Feature：Aromatherapy can relieve stress and relax the mind, and also help sleep.

• Purification stages：The higher the purification level of the air purifier, the more thorough the purification

• Weight：The lighter the weight, the easier it is to carry it to other places for use.

The Verdict: Berk D3S is Health Guardian
