How Long Should You Run Your Air Purifier

The short answer is that an air purifier should stay on 24 hours per day. But why? There are several factors to be considered.

The first is that the air purifier improves the air quality only when it stays on.

As soon as it turns off, unless the room is completely isolated from the external environment, the air quality would go back to its normal polluted values.

The second factor is just as important, but very few users are aware of it: an air purifier doesn’t clean up the entire indoor environment immediately.

It can take from 30 minutes to 2 hours to clean indoor air. Why is this important to know?

If you have an air purifier in the office, or if you have one at home, but you spend half a day in your workplace, you may wonder whether it makes sense to leave the air purifier on 24 hours per day. Can’t you just turn it on when you arrive at home or at the office?

You could, but you need to be aware that for the first 1 or 2 hours, you’d be breathing polluted air.

If you want to find a clean environment when you get home or at work, the air purifier needs to be working for a while.

You could purchase an air purifier with programmable features: for example, you could set the air purifier to turn itself on 1 hour before you get home or to the office.

This is an effective way to optimize the energy consumption of your device.

One of the main cons of leaving an electrical appliance always on is that it is going to consume a lot of energy.

We’ve already talked about programmable features, but another way that you can use to make your air purifying system more energy efficient is to isolate your room as best as you can.

Keep windows and doors closed, for example, so that new pollutants or other particles don’t come in. This way, even when the device is off, the air can remain clean.


When Should I Turn Off my Air Purifier?

Air Purifiers work effectively when you keep them on 24×7. But you can put the air purifier on low mode during the night if you are tired of its noise.

You can also turn it off if you’re going away from your house for long hours or days.

In case you do not have an allergy or respiratory problems, you can turn it on for some hours during the day or night.


Should I Put My Air Purifier on the Floor?

You should keep your Air purifier on a bedside table or counter because that way, it is able to take up the air and pollutants closer to the ceiling and is able to clean the air more efficiently and faster.

The timing depends on how large your room is and the setting of the air purifier.

The air in smaller rooms can be cleaned in 30 minutes, while larger rooms can take 2-3 hours. You can buy an air quality monitor to know if your room is cleaned or not.


Conclusion

Your air quality would improve only when the air purifier is on. For this reason, you should keep it working 24 hours per day. However, in this article, we’ve seen ways of optimizing its functions.
