Should An Air Purifier Run All Day?

Air purifiers have become a staple in many homes, helping to clean up indoor air and reduce the level of airborne allergens in your area. In fact, they have become so popular that one in four American homes currently own an air purifier. 

But the big question remains: should you leave your air purifier on 24/7, or is it better to give it a break? Let's dive into the pros and cons of running your air purifier all day to help you decide what's best for your space.

Benefits of Running an Air Purifier All Day

Probably the biggest benefit of keeping an air purifier on at all times is having constant and continual control of airborne pollutants and allergens, which carries numerous other benefits. 

Having the air purifier on at all times means that the indoor quality in your home or room will be at a high level almost constantly. 

Furthermore, you will prevent the buildup of pollutants over time, thereby reducing the risk of potential health issues associated with prolonged exposure.

Potential Disadvantages 

One big issue many people have with having an air purifier on at all times is the noise. While many modern high-quality air purifiers are designed to operate quietly, some models may produce noticeable noise levels, especially at higher fan speeds. This can be a concern, particularly in bedrooms or in an office.

For this reason, we make it a priority to control noise output from our air purifiers at Rabbit Air. Ultra-quiet operation is one of our key features and sets us apart from other air purifiers.

Another common consideration, cost of operation, is not that much of an issue once you analyze it more thoroughly. 

Many people are worried about the costs associated with running an air purifier all the time. However, air purifiers cost between  $0.02 and $0.32 per day to run, i.e. increase your monthly electric bills by $0.60 to $9.62 per month. 

Rabbit Air purifiers are energy-efficient by default and are Energy Star certified. You can use our electricity cost calculator to discover how much (or how little) it costs to run each Rabbit Air model.

Finally, keep in mind that running your air purifier non-stop could affect how long it lasts and how much upkeep it needs. You might find yourself changing filters more frequently and having to give the whole thing a good clean to keep it working as it should. So, when you're deciding whether to leave it running all the time or give it a break now and then, it's important to think about these maintenance tasks too.

Why Keep An Air Purifier Running All Day?

Deciding whether to keep your air purifier running round the clock depends on a few things. First off, you've got to consider how big the room is and how dirty the air usually gets. If you're dealing with a large space or there's lots of pollution around, it might be a good idea to keep that purifier running constantly to make sure the air stays clean all day long.

Then there's your own health to think about. If you or anyone in your home has allergies or breathing issues, having the purifier going all the time could reduce the number of airborne allergens in your vicinity. This can even vary depending on the time of year, whether it is allergy season, or if your pet sheds seasonally.

Best Practices for Air Purifier Usage

To get the most out of your air purifier, it's important to use it wisely. That means figuring out when you really need it and when you can give it a break to save some energy. You might set up a schedule based on when people are around and how much stuff is floating around in the air. That way, the purifier kicks in when it's needed most but takes a breather when things are quiet.

Keeping an eye on the air quality is also key. You can use sensors built into the purifier or get a separate monitor to see how clean the air is. If you notice a drop in quality, you can adjust the settings on the purifier to deal with it.

Finally, don't forget about maintenance. Regular maintenance is essential for keeping your air purifier in top shape. This includes tasks like changing the filters according to the manufacturer's recommendations, wiping down the exterior to remove dust and dirt, and checking for any signs of wear or damage. 

By staying on top of maintenance, you can ensure that your air purifier continues to function effectively and efficiently, providing you with clean and fresh indoor air. 


In the end, whether you decide to keep your air purifier running all day or give it a break now and then depends on a few factors. Consider the size of your space, the level of air pollution, and your own health needs. If you've got a big area or suffer from allergies, keeping it on might be the way to go. Just be mindful of the noise and the additional cost on your electricity bill if you got a larger model. And don't forget that regular maintenance is necessary to keep it humming along smoothly. With a little thought and care, your air purifier can be a real game-changer for your indoor air quality.
