How Long Should An Air Purifier Work (24/7 Or Not)?

The task of the air purifier is to keep the indoor air clean and safe for breathing. It does that by clearing out airborne pollutants from the air.

But how long does it take for the air purifier to clean the entire air of a room? Most importantly, how long should an air purifier work?

You should keep the air purifier on all the time. In fact, if you want to get the most out of your air purifier, you should leave it 24/7. And there is no harm in keeping the air purifier on all day.

But will there not be any problem with the air purifier if you leave it on all the time?

And what about the electricity bill? Well, those are some questions we will answer later in the discussion.

Is It Safe to Run the Air Purifier 24/7?

There is no major downside to leaving the air purifier on all day. In fact, the air purifier manufacturers have built and designed the devices to work like that.

To understand whether the air purification device should always be on, you need to understand what they actually do.

The primary purpose of the air purifier is to capture all the contaminants from the indoor air. It relies mainly on two core components.

The first one is the intake fan, which sucks the air inside. And the second one is the filter that purifies the air that the fan is taking in.

Nonetheless, polluted air is one of the continuous and pervasive problems you must deal with in this modern age.

Keep the windows and doors open for a while, and you will find that the air quality meter is warning you about the pollutants that are in the air.

So, if you were asking yourself should I run my air purifier 24/7, you should!

By doing so, you can ensure that the indoor air is free of contaminants all the time.

And that is something that we all want, right?

Will the Electricity Bill Be Too High If You Keep the Air Purifier on All the Time?

Now that you know the answer to the question of does an air purifier has to be turned on 24/7 let’s talk about the electricity bills.

So, there is really no need to worry about the electricity bills.

Here are the reasons why –

Most Air Purifiers Are Energy Efficient

Air purification devices have come a long way. Nowadays, most of them have the Energy Star certification.

Now, you might not know what makes this certification so special.

Well, the air purifiers with Energy Star certification are at least 25 percent more energy-efficient than most standard models.

In other words, energy-efficient air purifiers do not consume too much electricity to operate. So, you can keep your air purifiers on without worrying about electricity bills.

Air Purifiers Do Not Require a High Amount of Electricity to Run

The power rating for air purifiers is from 8.2 watts to 130.8 watts. Compared to other home appliances, that range is considerably low. For example, consider a regular refrigerator. Fridges typically have a power rating between 100 watts and 250 watts.

Many Air Purifiers Have Power-Saving Modes

A lot of air purifiers will come with auto modes. This clever mode automatically changes the speed of the fan. And it does that by checking the pollutants that are present in the air.

So, during the first few cycles, the auto mode will run the fan at high speed. These cycles will clean the air as fast as they can. And after most of the cleaning is done, the auto mode will detect the low presence of pollutants in the air. That is when the fan speed will drop to lower levels.

When the fan is not running at high speed, the air purifier will not take in the least possible amount of electricity.

It Does Not Cost Much to Keep the Air Purifier on All the Time

Depending on the model, running the air purifier will cost anywhere from 0.02 USD to 0.32 USD per day. So, you want to spend anywhere from 0.6 USD to 9.6 USD monthly. Now considering the typical electricity bill of a household, that is like 5 to 8 percent of the total bill.

Things to Consider Before Running the Air Purifier All Day

Before you plan to keep the air purifier on 24/7, you need to consider these crucial points:

Carry Out Regular Maintenance

Most air purifiers will primarily rely on the filtration unit for the process. And when you keep the device on all day, the filter will have a relatively high level of strain. But that is pretty normal! All you need to do is to ensure that you check the filter life from time to time and replace it when needed.

Place the Air Purifier in the Perfect Spot

Without placing the air purifier in the right spot, you can not get the most out of it, even if you leave it on 24/7. And when it comes to finding the perfect spot for an air purifier, you just need to keep two crucial things in mind.

Firstly, make sure that the spot is elevated from the ground. Secondly, ensure that there is no obstruction around the air purifier.

Enable the Auto Settings

The air purifier does not need to stay cranked up all the time. After the first few cycles, the indoor air quality will rise, and there will be less number of pollutants. In such cases, if the fan speed is high, the purifier will consume more electricity than it needs.

A solution to this issue would be to enable the auto mode on the air purifier. As mentioned earlier, the auto mode will analyze the air and adjust the speed accordingly.

Frequently Asked Questions

1. Can you run the air purifier 24 hours a day?

To get the most out of the air purifier, you should run it 24 hours a day. Through that, you can ensure that the indoor air has the highest possible purity and there are little to no contaminants in the air.

2. Should I leave my air purifier on all the time?

You should always leave the air purifier turned on if you want to ensure that the indoor air does not have any contaminants. And as the manufacturers design the air purifiers to operate all day long, they will have no issues.

3. How long should I keep an air purifier on?

It is better to keep the air purifier turned on all the time. However, if you do not stay in your home for most of the day, you can keep it turned off when you are outside.

Final Words

In order to have the best possible indoor air quality, you need to know how long should an air purifier work. As you can see, it is recommended that you keep it on 24/7.

By doing so, you can be assured that the indoor air will have little to no pollutants in it.
