Can an air purifier improve sleep?

The air purifier allows you to breathe healthy air, but can it help you improve your sleep? In our opinion, the answer is yes. The air purifier is the ideal companion to ensure clean air in the bedroom, as it allows you to breathe fresh air and helps you fall asleep faster and maintain a good quality sleep.

An air purifier for sleeping: what are the advantages?

Air purifiers are effective in improving your sleep. Thanks to the HEPA filter, these devices can purify the air by trapping 99.97 % of airborne allergens down to 0.3 microns, such as dust, dust mites, pet hair, pet dander, mould spores and many bacteria that cause nasal congestion and keep you awake. Using an air purifier allows you to control your allergies and sleep better at night.

In addition, the air purifier can emit white noise, which helps to facilitate sleep. Many sleepers fall asleep with white noise, a term for static frequencies that are mixed to create soothing ambient sounds.

This white noise is produced by the fan of some air purifiers, which can block out external noise to an appreciable extent. Therefore, it will help you sleep faster.

An additional reason to buy an air purifier to improve sleep is the fresh air it gives off. Did you know that we sleep better in a fresh and comfortable environment? Fresh air allows our body to better control its temperature, burn calories and rest more easily. So with this device you can recover physically and mentally faster.

What are the causes of sleep problems?

Insufficient sleep leads to fatigue, daytime drowsiness, lack of mental clarity and a reduced ability to use resources to solve problems. There are many possible causes of sleep problems. The following two are related to air quality.


One of the main symptoms of depression is poor sleep quality. People with this problem are able to fall asleep, but they wake up at dawn and are unable to go back to sleep.

A good environment is a prerequisite for maintaining an optimal state of health, which is achieved through regular cleaning, air purification and the removal of household chemicals. An air purifier is able to maintain the quality of indoor air at its optimum level. In addition, if it has an ionisation function, you should benefit from the benefits produced by negative ions on your morale.

Air hygiene

Hygiene is one of the common causes of difficulties in falling asleep. Even if you took a shower before going to bed, your room may still be full of smoke, smells and odours.

The problem is that these gaseous fumes tend to linger in the air and will keep you awake. Again, an air purifier is all you need to keep odours and smoke at bay. By using an activated carbon filter, many air purifiers can adsorb odours and fumes from your home.

7 sources of pollution that can affect your sleep

Air quality goes hand in hand with quality sleep and the air purifier is the ideal companion to help us sleep better. But what are the sources of pollution that can influence the quality of your sleep?

1. Carpets

Carpets are very common in homes and offices. They generally present two problems. Carpet always emits some type of volatile organic compounds (VOCs) through a process known as outgassing, especially when it is first installed. In addition, carpets are the best place to trap contaminants such as smoke, dust, dust mites and even pet hair and dander. These pollutants can cause bacterial growth and foul odours.

2. Electronic products

Electronic equipment in offices (computers, printers, photocopiers) emit varying amounts of VOCs, carbonyl compounds and particulate matter. The source attribution of VOCs in modern offices is rather difficult to identify because of the many components.

3. Kitchen equipment

Kitchen equipment such as gas cookers can produce carbon monoxide as a by-product. Carbon monoxide is one of the main causes of headaches and prolonged fatigue. Another by-product generated during cooking is nitrogen dioxide, which causes respiratory problems and inflammation of the eyes, nose or throat.

4. The new painted walls

The main indoor air quality issue with paints is the release of volatile organic compounds (VOCs), many of which are irritants or odourants, and may present other toxic exposure problems. The actual chemicals released by paints depend on their chemical formulation. They are the main cause of headaches and nausea and are recognised as a major source of VOCs in the indoor environment.

5. Pet dander

Your pets are the most likely to cause discomfort or trigger allergic reactions such as asthma and respiratory problems in your home.

While pet hair and odours are trapped in your furniture and clothing, pet dander can cause serious allergy problems.

6. Pesticides and other chemicals

The chemicals we use to kill household insects and fungi also cause air pollution, especially if you do not clean or ventilate properly after use. The chemicals can become airborne and cause a number of allergies, including to the eyes, nose and throat.

7. Tobacco smoke

The chemicals and smoke particles from cigars and cigarettes remain in the air for a long time. We are aware of the health risks caused by smoking, but second-hand smoke is just as dangerous and can cause heart disease and lung cancer.
