If your sleep time is disrupted by constant sneezing, headaches, or other allergic reactions, then the possible cause could be the environment where you are sleeping. You might find it hard to believe it, but your sleep can be disturbed if the area you live in has a low quality of air. The surrounding air can leak into your house and make your indoor air unhealthy.

In this article, we will be discussing the importance of air purifiers and the answer to your question, should I sleep with an air purifier on?

What Are The Causes Of Sleep Issue

There could be many reasons that you are struggling to have a good night’s sleep. The causes could be your mental or physical health conditions, but we will only be discussing the problems caused due to poor bedroom environmental conditions.

Returning to typical day to day works without having a good sleep can be a great turn off. It affects your mood and your health.

Let’s look at what causes sleep problems and how can an air purifier fix these issues.

The Air Quality

Air quality is the most crucial factor that makes up your environment. If the air around you is full of dust, dust mites, pollen, pet hair, or some odd odors, then not only your sleep time but everyday day work can be disturbed.


If constant sneezing, coughing, or headaches take up most of your time at night, then it is the fundamental acknowledgment that you are allergic to the pollutants present in the air. Since there is no cure for allergies, the possible solution could be getting a nighttime air purifier.

Do air purifiers help in improving sleep?

One of the possible causes of not resting well at night is the constant itchiness or the random cough or sneeze that awakes you. Such uneasiness while sleeping can be due to the pollen or pet dander present in the air. Or even the strong and weird odors.

So, do air purifiers help in improving sleep? The exact and simple answer is. Yes, it does. An air purifier is an appliance used to make the air quality in your house better. It does so by removing all the pollutants present in the air and making it easier to breathe. Having clean air that won’t trigger allergies and make breathing easier eventually makes your sleep time better.

Using air purifiers in night settings allows them to function quietly, which does not disturb your sleeping environment. In conclusion, The effect of air purifiers in improving sleep time is remarkable.

So Should I Sleep With Air Purifier On?

Air purifiers are manufactured to run all day long. Buying an air purifier whose performance doesn’t wear out after some time is essential. Many people, after purchasing air purifiers, claim them to be not useful. The reason for that is the way that the air purifier is being used. Air purifiers are a machine; they can run 24/7 without having to rest. Running an air purifier continuously is more effective than constantly turning it on and off.

When the air purifiers are turned off, the dust, pollen, and other pollutants can quickly build up in the earlier purified air. The air purifier will require more effort in cleaning the air when it’s turned on the next time and eventually consume more time and electricity.

Keeping the air purifier running while sleeping should be done if you are a victim of allergies or breathing sensitivities. Or just a light sleeper in general. There are air purifiers that operate quietly and even come with a night light to add comfort to your sleep time.

Thus, air purifiers’ benefits are best availed when kept running all the time, even while sleeping.

There are some features to look for when getting an air purifier that you will be using in your bedroom at night time too.

The most important feature is the noise that your air purifier produces. To have a good sleep, it is essential to have an air purifier that functions quietly. There are air purifiers that are loud even at the lowest fan setting and some that functions noiselessly, even at the highest fan setting.

The audible range of a refrigerator is 50 dB, and that of a good cleaner that functions quietly is 32-36 dB. The quietest air purifier can be as low as 15 dB. These are just some things to remember before choosing a nighttime air purifier for yourself.

Night Light
