How to Tell if Your Air Purifier is Working?

Author: | Latest Update On:

Whenever it comes to the Air Purifier, the first concern of almost everyone is that How to Tell if Your Air Purifier is Working? An air purifier, also known as an air cleaner is a tool or device that removes airborne contaminants in a room to improve the quality of indoor air. This device is claimed to be helpful for patients with allergies and asthma, and at minimizing or removing smoke from second-hand tobacco smoking. 

Do Air Purifiers Actually Work?

The world has never faced such a disastrous condition of its environment before. Being pollution at its peak, the air is as polluted inside our home just as outside. It makes using air purifiers a necessity these days. Air purifiers for home are now on the rise as a partial response to the air quality issues. But questions may arise if air purifiers are really reliable solutions to indoor pollutants. The answer is yes, to many extent.


Ultimately, the exact pollutants that are extracted by an air purifier depend on the model you select. Some versions are designed with a filter to capture particles when the air runs through it, while other versions neutralize other air particles without even filtering them. Another alternative is an air purifier that emits negative ions that helps in attracting positive ion air particles in order to neutralize them.

How to Tell if Your Air Purifier is Working?

In spite of the practical uses of air purifiers, it is hard to trust over something that you cannot see yourself. The pollutants that make the air dirty are not visible with the naked eye. In the same way, you can’t just intuit the air quality. Then, How to Tell if Your Air Purifier is Working?

We’ll be including a few methods in this post to test your air purifier. While there are many forms of air purifiers, we will only discuss how to inspect air purifiers using HEPA technology.

1. Taste the airflow of the air purifier:

An easy way of evaluating whether your purifier works is by inspecting the airflow from your purifier. There is a fan in the air purifiers that pulls out air from inside of the room. The purifier filters toxic contaminants out of the room and blows clean air out. If no air is coming out even when the purifier is on, your purifier may not be functioning properly.

Ideally, the fan shouldn’t work hard to draw in and blow out air. If the fan is very noisy, the filter may need to be replaced, or your air purifier may have another underlying issue. Equally, if there is no sound at all, it is probably not drawing in enough air to boost the air quality.

2. Check the filters:

A bad filter is one of the major reasons behind an air purifier that doesn’t work properly. The purifier forces the air to the filter that traps aggravating molecules, in order to clean up the air. As a result, the filter clogs up and needs a replacement. Many air purifiers come with a filter indicator that is typically a time indicator, only telling the recommended time to change the filter.

Thus, it is always a better idea to check the filter manually. You can be sure your air purifier is functioning well if you see any dust, lose hair, silts, or black spots in the filter, but not as much to clog it up completely. Also, a too clean filter means the purifier is not working at all.

3. Use an Air Quality Monitor:

You can know if your air purifier is working through an easy test. First, have the purifier read with the baseline air quality, then switch on your purifier. If there is any improvement in air quality when all doors and windows are closed, it can be ascribed to the purifier. If the purifier is on with little or no improvement in air quality for a long period, then be sure that your purifier is not working.

Benefits of Using Air Purifier

There is no doubt about the effectiveness of air purifiers to purify the air and improve the air quality of the room. However, your air purifier will probably not neutralize or remove all of the pesky particles from your house. That is because certain pollutants are able to stay on soft surfaces like furniture, bed, carpets, along with hard surfaces like the walls. Below are some of the benefits of using an air purifier:
