Air purifiers have become an understated yet quite necessary part of the modern home. If you own one, then you must already feel the difference that an air purifier can bring to your home and its surroundings. However, it is also true that air purifiers are not exactly the flashiest devices – there are chances that your air purifier may be faulty but you cannot tell. If you’re wondering, “how to tell if air purifier is working”, then you’re at the right place.

Lucky for you, there are a few ways to know whether your air purifier is working properly or not – especially if it’s been a while since you’ve bought yours. Once you’ve checked and made sure that nothing is amiss with your air purifier, you can go back to having it do its job in silence. 

However, don’t forget that air purifiers, too, need maintenance from time to time. But first, here are some easy ways on how to tell if air purifier is working or not. 

4 Reliable Ways To Tell If Your Air Purifier Is Working Properly

1. Use An Air Quality Monitor

An excellent and extremely precise way of knowing whether your air purifier is working properly or not is with the help of an air quality monitor. These are handy devices that are often used for telling the nature of particles in the air around you if any. 

As mentioned before, the results shown by the air quality monitor are very accurate. They can measure the constituents of the air such as oxygen, carbon dioxide, carbon monoxide, etcetera. The air quality monitor can tell you exactly what quantity or percentage of these noxious particles you have in the air around you.

How to Use an Air Quality Monitor

As you might have seen, these devices are quite handy and efficient when it comes to monitoring air quality. But how do they do so? Technically, they do this with the help of several sensors located inside the monitor itself. The oxygen sensor, for instance, takes in a small amount of oxygen and attempts to sense the contents of the oxygen. 

It then lets out an amount of energy that is somewhat similar to the amount of oxygen present in the air consumed. The process is similar for carbon dioxide and carbon monoxide as well. Hence, all you need to do is turn on your air quality monitor around the surroundings you want your air composition checked, and it can give you an accurate record of the same. 

With air purifiers, air quality monitors can be handy in knowing whether the former is doing its job. First, you’ll need to measure the air quality when the purifier is off – you can do this by placing the air quality monitor near the vent of the air purifier. 

This gives you an idea of the usual composition of your surrounding air. Then, repeat the process with the purifier turned on – this can help you see whether the purifier is making a difference in the air quality or not. Some air purifiers must have air quality monitors already fitted into them, but these can often be inaccurate and it’s best to check air quality by yourself. 

2. Assess Your Air Purifier’s Airflow

Your air purifier essentially works best when the airflow is allowed to be regulated efficiently. In this way, it can continuously take in air and then purify the same and propel it out. Hence, your air purifier’s fan is an important component that is responsible for the air purification process. If your fan is malfunctioning, then your air purifier is most definitely not working to its full capacity. 

Your air purifier’s fan should be working seamlessly – so if it’s noisy and billowy, then there might be something wrong with the air purifier’s filter. On the other hand, if it is extremely quiet and isn’t making any noises, then there might be something wrong with the fan and you’d probably need to get your air purifier checked.

Manually Check The Air Purifier’s Filter

After the air purifier’s fan, it is the filter of your air purifier that is hugely responsible for removing the surrounding air pollutants. Again, it comes right down to the working procedure of the air purifier itself. When the air purifier sucks in surrounding air, the contaminants are caught onto the filter which prevents them from being released back into the air – which effectively makes the air cleaner, but the filter dirtier.

 It’s recommended to change your air purifier’s filter every now and then since once the filter is chock full of dirt, there’s no way it can help in cleaning the surrounding air. Hence, manually check the filter(s) of your air purifier and figure out if it looks discolored or blotchy. If the answer is yes, then that’s most likely why your air purifier won’t work anymore. Get the filter replaced as soon as you can so that you’re not inviting bacterial accumulation.

Track The Built-in Filter Change Indicator Light In Your Air Purifier

As you now know the importance of changing your air purifier filters regularly, the easiest way to make sure that you can do so on a timely periodic basis is by relying on the built-in filter indicator in your air purifier. 

This indicator light is usually there to tell you when it’s time to change your air purifier’s filter – and if this light goes on, then the reason why your air purifier wasn’t working as well as before must be because it needs a filter change. 

However, this indicator light is not too accurate – you may get false readings sometimes. And if you live in an especially polluted city, then you need to be changing your air purifier filter well before the indicator light goes on. 

Final Words 

Now that you’ve seen how easy that was, you can do the same for your air purifier and verify whether it is really working or not. All you will need is to follow these methods and if you notice your air purifier not working as well as it used to, then it might be time to call the specialists since there may be a deeper problem with your air purifier. 

You can also employ the assistance of an air quality monitor any time you’re unsure, since it is one of the most accurate ways of telling whether your air purifier is really working. So now, assuage any doubts you might have about your air purifier and try out these methods right away!
