How Long Can You Leave Levoit Air Purifier On?

Air purifiers, especially those equipped with True HEPA filters, work by continuously filtering and circulating the air in your home. This process effectively removes allergens, pollutants, and particles to provide fresh air. The Levoit air purifier models, such as the LV-H132, LV-H128, and Levoit 300, are designed to be energy efficient and safe to use around the clock. However, it’s essential to understand that air purification is not a one-time event. Indoor air quality can change over time. The best way to maintain optimal air quality is to keep the air purifier running continuously.

Leaving your Levoit air purifier on all the time is optional for everyone. It depends on your specific needs and the factors contributing to your home’s indoor air quality. Let’s take a look at some of these factors.

Factors To Consider

  1. Allergies and respiratory issues: If someone in your household suffers from allergies, asthma, or other respiratory problems, it’s beneficial to keep the air purifier running continuously. The Levoit air purifiers, like the Purifier Core 300 and Core 400S, are equipped with advanced air filtration technology, including True HEPA filters, to remove allergens and improve air quality.
  2. Air pollution and outdoor factors: If you live in a highly polluted area, near a busy road, or in a city with a high pollen count, keeping your air purifier on all the time can significantly improve your indoor air quality. The Levoit Smart air purifier models, such as the Core 200S, can even be controlled remotely using your smartphone, allowing you to adjust the settings and monitor the air quality in real time.
  3. Pets: Pets can bring dander, hair, and odor into your home. Running your Levoit air purifier continuously can help keep these irritants at bay and maintain a fresher environment. The LV-H128 is an excellent choice for pet owners, including an activated carbon filter to reduce odors.
  4. Home size: The size of your home and the air purifier’s coverage area are essential factors to consider. A smaller air purifier, like the Levoit Core Mini Air, may need more than a larger space. In this case, you should run the air purifier continuously to maintain air quality. On the other hand, a larger model, such as the Core 400S, may be more efficient and cover a more significant area, reducing the need to run it 24/7.

Energy consumption: While Levoit air purifiers are designed to be energy efficient, it’s essential to consider the energy costs of running the device continuously. Some models, like the Purifier Core 300, have a Sleep Mode that reduces energy consumption while still providing air filtration and purification. You can also look for models with an Energy Star rating, which indicates that they meet strict energy efficiency guidelines set by the US Environmental Protection Agency (EPA).

  1. Filter replacement: The more you use your air purifier, the more frequently you need to replace the filters. Levoit air purifiers have a filter replacement indicator, like the Purifier Red Light on some models. It lets you know when it’s time for a new filter. Follow the manufacturer’s recommendations for filter replacement to maintain optimal performance and air quality.
  2. Noise levels: Noise can concern some users, especially when running an air purifier continuously. Levoit air purifiers are designed to be relatively quiet, with some models featuring a whisper-quiet sleep mode, like the LV-H132. However, choosing a model that suits your noise tolerance and the location where you plan to use the device is essential.


In conclusion, it is safe and efficient to always leave your Levoit air purifier on, depending on your specific needs and circumstances. If you or someone in your household suffers from allergies or respiratory issues, live in a polluted area, has pets, or needs to cover an ample space, running the air purifier continuously can be beneficial. The Levoit Core Mini Air, Core 200S, Core 300, Core 400S, LV-H132, and LV-H128 models offer different features to cater to various needs.

When deciding whether always to leave your air purifier on, consider factors such as energy consumption, filter replacement frequency, and noise levels. Levoit air purifiers are designed to be energy efficient and user-friendly, making them an excellent choice for improving and maintaining your indoor air quality. Ultimately, keeping your air purifier on depends on your needs and preferences. So, breathe easy and enjoy the fresh, clean air your Levoit air purifier provides.
