If the air purifier doesn’t have an indicator light, there should be a way to test the airflow. Usually, a cover can be removed to expose some measurement markings. By holding your hand against these markings, you can see how much air the machine is moving.

If the air circulation is not enough, it’s not doing its job. If the airflow seems fine, but you notice a drop in air quality or increased allergy symptoms, there may be another problem with your unit.

2- Check the Filters in the Air Purifier

One of the best ways to tell if your air purifier is working is to check the air filters. If they’re dirty, it means the machine isn’t doing its job. Some models have indicator lights that will let you know when to clean or replace the pre filters.

In that case, you’ll have to keep an eye on them and replace them when they start to look dirty. If the filters are clean, it doesn’t necessarily mean the air purifier is working properly, but it’s a good sign.

It’s also a good idea to check the filters every few months, even if they don’t look dirty, to ensure they’re doing their job.

3- Use an Air Quality Monitor

The best way to see if the air quality in your home is improving is with an air quality monitor. These devices measure various things, including volatile organic compounds (VOCs), pollen density, temperature, humidity and more.

If you notice that these numbers are going down or staying stable over several weeks or months, it’s a good sign that your air purifier is working.

Remember that an air quality monitor can’t always tell the whole story. For example, if you have a pet, their dander could be causing problems even if the VOC levels are low. So, it’s important to use other methods to judge whether or not your air purifier is working.

4- Use Chemical Tests Kits

Keep in mind that these tests should only be used as a guide. Also, you should always talk to your doctor if you’re having problems with allergies or asthma.


An air purifier can be a great way to improve the air quality in your home. But it’s important to make sure it’s working properly. By using these four methods, you can tell if your machine is doing its job or not.
