How To Choose An Air Purifier: 4 Factors To Consider

Air Purifier

Are you looking for an air purifier?

The process of choosing air purifiers isn’t straightforward as it seems. Several factors should influence your decision when it comes to this matter. After all, not all air purifiers are the same. In fact, almost all air purifiers today can be considered unique in their own right. 

If you are searching for an air purifier, you need to know the fundamental considerations that could distinguish the good ones from the bad ones. In this guide, we will go through each of these considerations, which, in turn, gives you the opportunity to find the most suitable air purifier for you. 

How To Choose An Air Purifier?

Air purifiers are designed to remove a significant amount of airborne pollutants and pathogens in a given space. Hence, you have to make sure that the air purifier you get can meet this particular expectation. 

To narrow your choices, just refer to the following guidelines. 


Perhaps it is quite a bias when we say that there are particular brands that have a better reputation when it comes to air purification systems than their counterparts. However, it’s a reality that consumers have to accept. 

You see, some brands stand out in the market because of the finesse and quality of their products. They gained the trust of their clients because their air purifiers work. And that’s not something that you can ignore. 

Narrowing your options through brands is a logical thing to do. That’s one way of reducing the time and effort needed in comparing air purifiers. Fortunately, there are numerous reputable manufacturers of air purifiers in the market today, such as HisoAir. We recommend that you check the provisions of these manufacturers so that you’ll determine whether or not they can meet your requirements. 

Floor Size Of Your Space

Interestingly, it is not all about your air purifier. You see, the ideal air purifier varies from one person to another. Some require powerful air purification, given that their homes and offices are big. Others only need personal air purifiers, as they don’t need to deal with expansive spaces. 

Air purifiers have specific ratings when it comes to the area that they can efficiently clean. Some air purifiers are designed to work in small spaces or single-room applications. These are those air purifiers that are rated to work on 100 to 200-square-foot rooms. 

Of course, you can also find whole-house air purifiers. They are those who can purify at least 700-square-foot rooms. These appliances are powerful; hence, it is a given that they consume more electricity. 

Surely enough, you don’t need large air purifiers if you aren’t dwelling on expansive spaces. That’s pretty pointless. Oppositely, an air purifier that is too small for your area would not generate significant improvements in your indoor air quality.

The point here is that you need to match the air purifier to the actual size of the area that you want to be cleaned. In this way, you will get the most out of the air purifier without spending too big. 

Filtration System

One of the essential considerations in choosing air purifiers is their filtration system. The latter is the heart and core of these air purifiers. Without them, the air purifier won’t be able to do anything. 

There are different types of filters installed in an air purifier. Needless to say, these filters are designed to trap or capture specific types of airborne contaminants. If you want to get the ideal air purifier, the following filters should be present. 

  • HEPA Filters – A HEPA filter is designed to capture 99.97 percent of microscopic contaminants in a given space. Hence, it is capable of removing pathogens, allergens, bacteria, and viruses. This particular filter is essential in protecting yourself against respiratory diseases. 
  • Pre-Filter – A pre-filter works by trapping large debris in the air, such as pet hair. This particular filter is necessary to prevent damages to the HEPA filter. After all, HEPA filters are sensitive; their performance deteriorates if they have dirt accumulation. 
  • Activated Carbon – An activated carbon filter reduces the presence of smoke, VOCs, and chemicals in a given space. Technically speaking, these carbon filters are used to make indoor spaces fresher by reducing odor-causing factors. 

Now, air filters aren’t panaceas to keep your air free from disease-causing contaminants. One way or another, you would need extra protection, especially if you are residing in regions or areas where air pollution is rampant. Here, you would need high-quality PPEs provided by notable manufacturers such as HisoMedical

CADR Rating

The majority of the air purifiers today have a Clean Air Delivery Rate (CADR). This is a system of measurement created by the Association of Home Appliance Manufacturers (AHAM) to help people assess the effectiveness of an air purifier in removing specific contaminants in a given space.

For instance, if the CADR for pollen is 100, this means that the air purifier can lower the presence of pollen in the air by adding 100 cubic feet of clean air every minute. Of course, the higher the CADR, the more pollutants the air purifier can capture. It also means that the air purifier can work more in large spaces. 

According to Consumer Reports, the ideal CADR for those who are worried about COVID-19 is 240 or higher.  

It is also notable that some air purifiers only have one CADR number for specific pollutants, such as dust, pollen, and smoke. Others have different figures or designations for these particulates. 

However, the Environmental and Protection indicated that typical air purifiers don’t have effective CADR ratings to deal with large pollutants such as allergens generated by insects. Furthermore, one should know that the CADR rating of air purifiers only represents the ideal settings. The actual performance is still influenced by external factors. 


Aside from the factors we mentioned above, there are still other factors that you might want to consider. Among these are the air purifier’s noise level, ergonomics, and portability. These things would help people get the most out of these air purification systems. 

Regardless of your needs and preferences, the importance of air purifiers isn’t something that can be downplayed. These devices could help you breathe better while inside your home. They can also protect you from respiratory disease by trapping harmful pollutants, chemicals, and gasses.
