Do you leave your air purifier running all day and is it worth it?
This is a question that many people wonder about because they want to make sure their family members are breathing clean and healthy air.
However, not everyone has the same opinion on whether or not it's necessary to keep the air purifier running all day.
Some believe it would be best to leave it on 24/7, while others think turning it off at night will help with energy costs.
But where to start?
As experts in our field, we discuss the following in this article:
In this article, I will explore both sides of the argument so that you can decide what works best for your lifestyle.

You may have heard that it's a good idea to leave a household air purifier on all day.
However, some people think you should turn it off at night so that your energy bill is not as high.
Let's explore both sides of this argument to better understand the consequences and benefits of each option.
Some experts believe you shouldn't run an air purifier while you're gone because they say most homes don't need one, unless someone in the house has allergies or asthma¹.
Suppose everyone who lives in the home doesn't suffer from any respiratory issues. In that case, these professionals recommend turning the device off when no one will be around to benefit from its effects.
They argue that leaving an air purifier turned on 24/7 wastes electricity and that a residential air cleaner will not remove all contaminants from the air, especially those heavier than air, such as carbon monoxide.
Alternatively, some people think leaving an air purifier on all day can help you avoid breathing in harmful pollutants and chemicals as long as your device has high CADR² ratings.
While some experts say these devices do little more than circulate dirty rooms into clean space, others claim they reduce common household odors like pet dander and cigarette smoke, while trapping larger particles such as dust, pollen, mold spores, grease, and ash.
As for energy costs associated with running these machines 24/365? Some purifiers cost pennies per hour to run, while more advanced models could set you back a few dollars each month³.
Some people will tell you that it's perfectly safe to leave your residential air purifier running 24 hours a day.
However, others may argue that this is not safe because they're concerned about both safety and energy costs.
The truth?
There have been no confirmed reports of anyone getting sick or injured by leaving their home air purifier on while nobody is at home.
But could there be risks I don't know about simply due to lack of research?
Someone might get hurt if they come across a machine with exposed blades or hot coils, but these types of injuries would likely happen when the device was turned off as well.
In most cases, an indoor humidifier⁴ poses more risk than an air-purifying unit does, mainly because it can spill water and electrocute you if not handled properly.
If you wonder whether it's better to leave the air purifier on all day, there is no right answer.
Some experts say leaving your device running while you're gone could help reduce allergens⁵ and contaminants in the home, while others argue that turning off the machine (or at least lowering its settings) will save energy costs.
In terms of health risks associated with these devices?
You should be perfectly safe as long as you keep them clean and maintained according to manufacturer recommendations.
Remember, regardless of how often they run, residential air purifiers cannot remove 100% of pollutants from indoor spaces⁶.
This is because a filter can only catch so much dirt before it becomes overworked and ineffective, especially if you live in a place that has harmful gases or chemicals in the air.
Suppose your home is one of those that normally require an air-purifying machine. In that case, leaving it on while nobody is home may be beneficial for reasons such as reduced odors and improved air quality, even though some purifiers do cost pennies to run each hour.
On the other hand, turning these units off when no one will benefit from them could help lower energy costs. This alone probably won't make much of a difference unless you live somewhere with very expensive electricity rates.
Air in a home is constantly being exchanged with the air outside. This means that outdoor pollutants may enter your home at any time, and indoor contaminants can leave it just as quickly.
This does not mean you should turn off your residential air-purifying unit every night, because even though these devices are built to improve overall air quality.
They cannot remove 100% of household chemical vapors or dangerous gases from interior spaces like gas stoves, for example (which is why carbon monoxide alarms⁷ exist).
In other words, an indoor purifier might help clean up some odors. Still, it will never protect against hazardous chemicals or combustible fumes released by appliances such as furnaces and ovens.
Essentially, if something is going on inside your home that could be potentially dangerous to you or someone else, it would probably be a good idea to leave the air purifier on all day, because this will help reduce airborne contaminants.
If not?
Turn off the machine and save some money for yourself by cutting back on energy costs.
Air pollution is a big problem⁸. If you have an air purifier, It's important that you set up your schedule appropriately so that the device will run all day long.
For example, some people leave their devices on while at work and forget about them until they get home again later in the evening.
However, this means half of the time when you need clean air, and most are lost because no one has been around to activate it.
One solution for this problem is to leave the purifier on all day long. Some people are concerned that leaving it on constantly will put an added strain on your electric bill, but this isn't true.
Studies have found that air purifiers use no more electricity than a standard light bulb⁹. In fact, many home appliances like TVs and heaters use significantly more power than they do.
The best way to ensure that you get clean air throughout every minute of the day is by making sure your device runs consistently for as long as possible each time you turn it on.
If someone accidentally forgets about their purifier while at work or school, there's less chance of them coming back home with dirty air if they don't need to spend hours cleaning up after the machine.
No, leaving your air purifier on while you’re out of the house will not damage its components or cause any problems for yourself over time.
However, this does depend on which device you have and how often you use it. Some models may require more maintenance than others to ensure that they continue working properly as long as possible.
The best time to turn on your purifier is as soon as you get home from work in the evening or when you wake up in the morning before leaving for school. This way, it has a good amount of time to clean all of the air breathed throughout each day.
It’s important to keep costs down as often as possible, but leaving your purifier on won’t increase the total amount of energy you use.
Many appliances such as microwaves and televisions are more expensive than a simple air cleaner that can help protect against allergens and toxins in the home environment.
It’s generally fine to leave your air purifier running for longer than one day at a time, but it’s important not to let the device run for more than two or three days without interruption.
This will ensure that everything functions as well as possible and no parts wear out too quickly in only a short period.
If you've been wondering whether to leave your air purifier on all day, the answer is yes. Air purifiers are designed to work continuously to maintain clean and healthy indoor air conditions around the clock.
Leaving an air cleaner running overnight will help keep allergens like pet dander, dust mites, pollen, mold spores, and other airborne particles from accumulating in your home while you sleep.
Not only does this create a healthier environment for you and your family members, but it also prevents any potential health issues that can arise because of these environmental pollutants being present at high levels.
Therefore, I can strongly recommend that it is worth leaving your air purifier to run all day.
