Can I use an air purifier with windows open?

You can have the windows open, but it is best not too!

Windows Open?

It is not necessary that you close your windows when you use an air purifier. However, if you want to ensure the latest air quality inside and the outside, then it is advisable to close your windows.

Nevertheless, in order for an air purifier to work properly, all of its sensors must be working so that it can detect any kind of pollutants that are present inside or outside of the room. If a window is open while using a purifier then this will create a barrier and the sensor will not be able to detect any pollutants in or out of the room which can lead to decreased performance levels with time as well as possible damage on the health level.

In order to prevent this from happening and to allow the air purifier to be able to work properly you should always use it in an area where there are no windows. If you are using it for a room that has windows then make sure that they are open while the room is being used as well.

You can also close your doors or try to place your purifier in a different part of the room so that it does not affect either the air quality inside or outside of the room, even if you are using an air purifier with windows open.

If you are using a purifier with windows open then make sure that you do not leave it on while having windows open for long periods of time. Also, check the air quality regularly in order to ensure that the purifier is working properly.

Where should you put an air purifier?

It is often advised to put an air purifier in a major entrance area of the home, such as a hallway or living room. This will help trap the allergen and other pollutants when they enter, keeping them from spreading throughout the home. If you are using an air purifier in one of these areas then it is good to keep your windows open so that they can keep enough oxygen flowing into the room.

If you are using an air purifier for a different room then make sure that it is placed close to a major entrance or exit, which will also allow any polluted air to flow out of the room.

As you can see, it is not necessary to close your windows to use an air purifier. However, if you want to get the most out of your air purifier then it is better to have a room without open windows. The best way to choose the right place for your air purifier is to take into consideration any furniture that may be in the way as well as whether or not you open or close your doors when the air purifier is in use.

Also keep in mind that if someone smokes inside of your house, you should place your air purifier near their area so that it can filter out all of the smoke.

Where should you not put an air purifier?

It is important to keep an air purifier out of the reach of children because they may try to play with it or take it apart. This could cause damage to the unit, the room, and even result in severe injury. It is also advised not to put an air purifier near any appliances that use gas or oil. These types of appliances release harmful chemicals that could compromise the health and safety of anyone near an air purifier. If you do not want your purifier smelling like your food, then do not put it close to your kitchen area either.

As you can see, there are many things that should be taken into consideration when it comes to where you should place your air purifier.

Can you leave air purifier on all the time?

Yes, you can leave your air purifier on all the time. In order for your air purifier to work properly, it needs to be cleaned regularly so that it is able to handle the job and not become clogged up. It is always recommended that you clean your air purifier at least once a month or more if needed.

Overall, it is safe to leave an air purifier on all the time so long as it is being cleaned regularly.

Are air purifiers a waste of money?

With an air purifier, you will be breathing clean air every day which means that your health will be greatly improved.

Instead, you can simply clean your air purifiers regularly and it will help to keep your home or business clean as well as your health.

Which air purifier is best for me?

The best air purifiers will be based on your own personal needs and what is important to you so make sure that you choose something that suits all of your needs before making any purchase.


When it comes to selecting and using an air purifier, you will need to consider a number of factors such as your personal health, physical environment, lifestyle, and how much you want to spend on it. However, depending on where you live, the amount of pollution that is present outside of your home or office is likely different so this may also need to be taken into account when choosing an air purifier.

One thing that should not be neglected when selecting a new air purifier is the cost because there are many different types available.
