Purifying Air in Large Spaces: How do air purifiers work

How does an air purifier work in large space?


Air purifier is one of the best ways to keep your home or office away from harmful pollutants and allergens. However, people have a lot of confusion about the air purifier for large space. The following information provides answers to some common questions about using air purifiers in large rooms, including if you have allergic symptoms, how air purifier works,whether they are effective, and which filter should be used when purchasing air purifiers. 

To understand whether the air purifier works in a large space, it is important to check its CADR value and other important functions, such as filter, sensor, noise, energy consumption and intelligent technology.

A high CADR value means the purification capacity of the air purifier. If an air purifier with a high CADR value is used in the same space, the air circulation times will be more, and the air will be cleaner and fresher. 

Before purchasing any product online, you should check online reviews, because these reviews can be very helpful to determine whether a model is different in terms of performance and reliability.


Jafanda air purifier has these certifications; Check whether the air purifier has passed the professional certification of EPA, CARB, CA65, FCC, ETL, AHAM, Energy Star, etc.

The same principle applies to see which product is most suitable for cleaning large spaces such as offices or living rooms. We have many different choices, so it may take you some time to find out which product is the best! 

One of the best ways to determine whether the air purifier is effective in a large space is to check the room size and match it with the CADR value. Generally speaking, it can ensure that 4 to 5 cycles per hour are appropriate.


The value of CADR (clean air delivery rate) is an indicator to measure the working condition of the air purifier in the room. It is measured in cubic feet per minute (CFM), which means how many cubic feet of fresh air are purified per minute. The higher the number, the more effective your air purifier will be in cleaning large spaces such as home or office. At present, AHAM only uses particulate matter to evaluate the purification capacity of air purifiers, and there is no evaluation method for VOC pollution.


How to use air purifiers in large family rooms

To clean large rooms or houses, use a machine every 1000 square feet or so. If there are many rooms or floors in your home that need cleaning, please also place small air filters in these spaces and open them at different times of the day to ensure the air purification effect! 

High-end air purifiers should have HEPA filters, activated carbon filters and prefilters, which will help to remove all kinds of pollutants, not only particles, more effectively in a large space.

If you live in a large space, you need to consider investing in a large CADR air purifier, which has a HEPA filter, an activated carbon filter and a prefilter. These can be combined to form a whole to facilitate cleaning and replacement, and ensure sealing. H13 real HEPA filter is the most effective in removing pollens, dust, bacteria, viruses and other pollutants in the air. It can capture 99.97% of allergens as small as 0.3 μ m (compared with 1 mm of human hair). The activated carbon filter air purifier is also very effective in removing odor in the air and absorbing VOC and other gases. The prefilter can help intercept large particles such as pet hair before they reach the HEPA or activated carbon filter. If they are cleaned with a vacuum cleaner under normal conditions (they should be cleaned every 2 weeks), it can prevent these too many particles from blocking and affecting the air flow.




By taking the time to study the appropriate air purifier for your large space, you will be able to protect your family from the impact of harmful pollutants. It is also important that you choose air purifiers with HEPA filter and activated carbon filter, because they can remove more pollutants than other types of filters. The best thing about using air purifiers in large spaces is that they are equipped with sensors. When the level of pollutants is detected to be higher than the normal range, the air purifier will automatically adjust the wind speed to purify!
