Considering the times we live in, air purifiers are now a must-have in every home. That said, not many homeowners are familiar with air purifiers and how they work.

In this post, we’ll answer some of the common questions we get about air purifiers, including how long they should be left running:

Will the Settings of the Air Purifier Make a Difference?

Air purifiers have different settings that can be adjusted depending on the user’s needs. The most common settings are the fan speed, the filter type, and the air quality sensor. The fan speed determines how much air is drawn through the purifier, and the filter type determines what kind of particles are removed from the air. The air quality sensor monitors the air quality and adjusts the settings accordingly.

Most air purifiers will have a setting for the time the purifier is run. This is typically in hours and is usually adjustable. The longer the purifier is run, the more effective it will be. 

The settings on an air purifier can make a difference in the air quality, but they will not always be effective in removing all contaminants. It is crucial to choose an air purifier that is right for your needs and to run it for the recommended time.

Is It Safe to Keep My Air Purifier Running At All Times?

When it comes to air purifiers, one of the most common questions we get asked is whether or not it’s safe to keep them running all the time. The short answer is “yes”, it is considered perfectly safe to keep your air purifier running at all times.

There are reasons why you might want to keep your air purifier running all the time:

  1. If you have asthma or allergies, keeping your air purifier running can help to reduce your symptoms.
  1. If you live where there’s a lot of air pollution, running your air purifier can help to reduce the number of harmful particles in your home.
  1. If you have pets, running your air purifier can help to reduce the amount of pet dander in your home.

Of course, there are several things to keep in mind if your air purifier runs all the time. First, choose an air purifier with a high CADR rating. The CADR rating measures an air purifier’s ability to remove airborne contaminants. The higher the CADR rating, the more effective the air purifier will be.

Also, be sure to change the filter in your air purifier regularly. Most air purifiers come with a filter that needs to be replaced every few months. If you don’t change the filter, your air purifier won’t be as effective at removing contaminants from the air.

How Long Should You Be Running Your Air Purifier Every Day?

Assuming you have a quality air purifier, you should run it as much as possible to keep your indoor air quality high. However, there are things to take note of when deciding how long to run your air purifier daily.

The size of your purifier and the size of your room will impact how often you need to run your purifier. If you have a large purifier for a small space, you won’t need to run it as often as you would a smaller purifier in a larger room.

The type of air purifier you have will also impact how often you should run it. Some air purifiers are designed to run continuously, while others have an automatic shut-off feature that kicks in after a set period.

If you have allergies, you may have to run your air purifier more often to help keep your symptoms under control. The same goes for smokers in the home – running an air purifier can help to remove smoke and other airborne particles from the air, making it safer and more comfortable to breathe.

It would help if you aimed to run your air purifier for at least 12 hours daily. This will help you ensure that your indoor air quality stays high and that you do everything possible to protect your health.


An air purifier can help make sure that your indoor air is clean. However, you should first understand how the air purifier works and what type of purifier you own to better understand how long you should run it.
