How Many Hours A Day Should You Run An Air Purifier?
Most air purifier experts will tell you that running your device 24 hours daily will provide you with the cleanest air.
However, this doesn’t mean you should run the machine on the highest setting for the entire time.
It would be best if you run the air purifier on a high setting for a couple of hours to get the best results.
This will remove most of the airborne particles and clear the room. If you have a larger space, you may wish to increase this time.
After running it at full speed for two hours, you can return the settings to the lowest option.
That said, this will help maintain the level of clean air in the room throughout the rest of the day.
Is It Safe To Leave An Air Purifier On All Day And Night?
Many electrical devices that serve an ongoing purpose have been designed with continual use in mind.
For example, consider your fridge or freezer, which remains plugged in and running 24/7.
Your air purifier is no different.
As a matter of fact, it has been manufactured in such a way that continuous use won’t cause any safety hazards.
However, it is worth remembering that running the air purifier all day and night will mean the filters must be replaced more frequently.
Benefits Of Leaving An Air Purifier Running All The Time
You will likely appreciate running an air purifier all the time.
Why?
Because it is the best way to tackle air problems within the home, let’s look at the benefits of running the device continuously.
- You will get a better night’s sleep thanks to the ability to breathe more freely – this is especially important for those with allergies, asthma, and other breathing conditions.
- The air in your home will constantly be free from bacteria, so you and your family will remain healthier.
- It’s no secret that humans can create some questionable odors, but running your air purifier all the time can eliminate these odors, leaving your home fresher and more pleasant.
- Some building materials contain harmful chemicals, and these can be passed into the air and, as such, breathed in by you and your family. Your air purifier will ensure that VOCs are effectively removed. Inhaling these particles could potentially play a part in developing lung cancer.
- Outside fumes can easily penetrate the home if you live in a significantly polluted urban location. Running an air purifier daily at night will remove these fumes from your home.
Disadvantages Of Leaving An Air Purifier On 24/7
While there are many reasons why continually using your air purifier is excellent, there are a few downsides.
However, it is worth remembering that the advantages far outweigh the disadvantages.
- Your energy bill may be slightly higher, thanks to the additional power you will use. However, many air purifiers are made to be energy efficient, so that this increase will be minimal.
- The filter must be replaced frequently. If not, dust and dirt will build up, making the air purifier far less effective.
- If you are running an ozone air purifier, this could potentially do more harm than good.
Do Air Purifiers Help With Sleep While Running Overnight?
Air purifiers are great for helping you obtain better quality sleep, and there are many reasons for this.
Primarily those with lung conditions and allergies. And even sleep apnea will likely find relief from their conditions when using an air purifier overnight.
Often, allergens will settle during the night, increasing your body’s reaction to them.
Think about how bad your hay fever gets on those summer evenings.
Running your air purifier through the night will remove these allergens, leaving you free to sleep peacefully.
Additionally, many air purifiers on the market emit a low hum, and this white noise can help people drift off to sleep more easily.
Studies have shown that white noise has a positive impact on sleep quality.
So even if you don’t suffer from breathing difficulties, the gentle sound could be beneficial.
What’s more, some air purifiers out there can cool down a room. And can act as a temperature control system, like the Dyson Hot + Cold.
For example, sleep is much more easily induced when you are in a comfortable environment.
Summary – Is It Ok To Leave An Air Purifier On All Night?
You can leave your air purifier running all night, and it will not do any harm.
If anything, this is the preferred mode of operation as you can maintain continually clean air throughout the home.
This can aid with sleep and help those struggling with allergies.
