Have you ever wondered, how long should you run an air purifier for? An air purifier is a common sight in many households. This is in many cases a necessary decision, as modern homes are being built “hermetically sealed” to be more energy efficient. While this is more to cut your energy bills, “sealing” doesn’t allow your home to breathe properly.
Harmful substances get stuck in your home and linger there for long periods, and the lack of natural ventilation makes it impossible to maintain optimal air quality.
An air purifier will improve your overall indoor air quality and in turn improve your overall health. We tend to think that only the air outside our homes is harmful to our health, yet recent studies in the field have shown that indoor air pollution levels can be more than 2-5 times higher than outdoor pollution.
But at the same time, the majority of people who own air purifiers ponder the question, “Can I run my air purifier all the time?” So, How long should you run an air purifier? Let’s find out!

Should I run air purifier on all the time?
You are supposed to run your air purifier all the time, 24 hours a day, 7 days a week.
Usually, air purifiers contain an advanced sensor that controls the fan speed to save energy. As a result, they can be used throughout the day without any issues.
An indoor air quality indicator is included with air purifiers. If you are happy with the indoor air quality, there is always the option to shut down the air purifier unit for a few hours to conserve more energy.
But if you have sleep disorders, a good idea would be to run your air purifier on the lowest setting.
How can I make my air purifier work faster?
The ability of an air purifier to keep the air clean and maintain a high level of air quality depends on a number of factors. Here, we’ve included some useful advice so that the air purifier works efficiently to maintain clean air quality at all times while also being comfortable to be around while it’s operating.
CADR, or clean air delivery rate, is basically how much air is being cleaned per hour. It is usually expressed in cubic meters per hour. With this, you get an idea of the air purifier performance you’ll have and the amount of air changes per hour that the device can give you.
In general, the more irritants the air purifier can remove and the bigger the space that can be cleaned, the higher the number.
The CADR rating is determined in cubic feet per hour and is usually used for airborne particles that have a size of a dust mite.
Features of the microclimate, such as drafts or dampness, can prevent an air purifier from reaching its base performance and cleaning all the air in your room.
Keep in mind that for a typical room size, most air purifiers do not have enough air displacement capacity to remove irritants associated with house insects. Otherwise, you wouldn’t be able to purchase an air purifier to clean the air in your room. Choose an air purifier whose CADR is appropriate for the room size.
CADR is usually listed by the air purifier manufacturer on the packaging.
Air extraction rate
Because it counts the number of times the air in a space is recirculated and altered in an hour, a high fresh air extraction rate and air changes per hour are also required.
The air purifier has a maximum capacity suitable for your bedroom. It is important to consider the size of your bedroom in square feet. The size of the room each air purifier can clean is different, and you need one that can filter all the dirty air in your bedroom.
In addition, if you have a room that is less than the specified maximum power of the air purifier, this means that you will purify the air in the same room more times while not even being on the highest setting.
The square feet size and design of the air purifier are suitable for your room. It’s very likely that if you have a small or medium bedroom, you don’t need a very large air purifier to take up all the space, otherwise, you’ll need multiple air purifiers working at low speed.
The size and design of the air purifier should also be considered when choosing an air purifier for the bedroom. For example, the Aerotronic 360 has a maximum capacity of 40m², perfect for any bedroom, and the small size is perfect for people with limited space.
Type of filters
A typical residential air purifier consists of a fan and a set of filters that collect particles of air pollutants.
HEPA (high efficiency particulate air) is the main air filter element in many air purifiers. HEPA filters were originally developed for the equipment of ventilation systems in medical institutions and premises with increased requirements for air purity; the technology is widespread and is used in industrial and domestic air cleaners.
A HEPA air purifier work principle is quite simple: the indoor air is driven through the filter by the air flow of a fan and thereby freed from dust particles. Even on the basic fan settings, a usual HEPA filter traps more than 99% of even the smallest particles with a size of 0.3 microns or more, including pollen, fungal spores, pet dander, smoke particles, dust mites, and other harmful particles and other airborne pollutants.
Therefore, HEPA filters are used in vacuum cleaners or air purifiers that are recommended for people with allergies.
Also, most air purifiers utilize activated carbon filters. An activated carbon filter physically absorbs the molecules of the odor-causing gas through its pores. However, these air purifiers work is not very effective when used in a high-humidity environment, as carbon filters cannot clean indoor air in these conditions.
Also, carbon air filters are not effective in removing low molecular weight gases such as formaldehyde, sulfur dioxide, and nitrogen dioxide. Therefore, in indoor air cleaners, it is used in combination with other filters (Usually a HEPA filter).
Keep your room clean
When you run your air purifier, it can only remove indoor pollutants if they are suspended in the air. Heavier allergens, such as mold, pollen, and other pollutants, settle to the ground so quickly that the air purifier cannot catch them.
The best way to improve the air quality in your home is to remove contaminants that have settled on surfaces. You do this by doing regular cleanings, such as vacuuming, dusting, and disinfecting.
Without this, the air purifier will be ineffective in improving indoor air quality and keeping the indoor air clean of airborne pollutants, which is a serious allergy foundation.
Thus, even if you currently run an air purifier, you should still consider doing the usual cleaning routine.
When choosing an air purifier, you should pay attention not only to its functionality and its ability to keep a high air quality, but also to the noise produced when you run your air purifier. The noise generated by most household appliances plays a very important role in our lives, and this also applies to the air purifier.
We must take into account the fact that on the most polluted days, we will use the device with the greatest efficiency, and this is reflected in the noise generated.
The higher the intensity, the more noise the device produces (especially if you have an ozone generator). If you are a light sleeper, you should find out how many decibels the device produces; in comparison, a standard refrigerator produces a noise level of around 50 decibels. Otherwise, just set the air purifier in standby mode.
How often should I run an air purifier?
To maintain health, doctors recommend running an air purifier all the time, 24 hours a day, so that you only breathe purified air. Manufacturers guarantee the operation of the device for 8 hours a day. Therefore, when using the air purifier around the clock, it is necessary to change the filters before the declared service life as well as to look after the device’s energy consumption.
Is it OK to leave air purifier on all night?
You can sleep next to the air purifier, leaving the device running all night. It is important to make sure that it is installed safely and that the steam is supplied correctly. It should be distributed throughout the room.
Is it better to sleep with an air purifier?
Yes, it is! As we have mentioned earlier, the air purifier helps you maintain the clean air in the room. Your bedroom is the place that you spend the most time in while at home, so it would make perfect sense to keep the air purifier running in it during the night.
Do air purifiers remove dust?
The air purifier, depending on the degree of cleaning of the filters and their set, removes from the rooms of an apartment or house: dust particles, smoke, odors, pathogenic bacteria and microbes, animal hair, fluff and bird feathers.
Clean air is the key to health and excellent performance, and it is important to know how long should you run your air cleaner. With an air purifier running in your house, the threat of the spread of viral diseases is eliminated, the concentration of negative ions that is best for health is maintained, immunity is maintained, and well-being improves. Filter sets destroy all types of air pollution, disinfect and ozonize it.
