How long should you run an air purifier

How long should you run an air purifier

The run of the air purifier depends on the quality of the air Purifier. An air purifier is a necessary device that helps eliminate indoor impurities such as dirt and container. Some people are quiet about running air purifiers all day, citing energy use. That’s why people wonder how long an air purifier should run a day. It is based on numerous things such as filters, CADR, room size, air displacement, and air circulation. Most air purifiers take half an hour to two hours to clean the whole room perfectly. You can also run the air purifier for more than a few hours with full control and then back at a lower speed to maintain indoor air quality. An air purifier needs thirty minutes to two hours to clean the air in a room. If you have an air purifier in a room of 300 square feet, it needs an exact(CADR) of 195 and a standard Air Changes per Hour (ACH) of 4 that require 15 minutes to purify the air in the room. So, it’s best to run the cleaner extensive precisely than essential, mainly when you have pets or allergies. In calculation, you need to keep your air purifier constantly running to maintain fresh air in your room.


How long should I keep my air purifier on?

If you just started using an air purifier, you will often be wondering how long I should run my air purifier to clean the air for maximum results or how fast air purifiers work. Fear not, as we have compiled and addressed some of the common questions that relate to an air purifier’s runtime. Anyhow you are a student or a master in the air purifying world, give this post a quick run-through. At least 12 hours a day, but for the best result, we approve possession of your air purifier run 24 hours a day as dust, and driting particles will circulate continuously all around the day. With sustained clean air, you can breathe more easily without allergies like cough or sinus being triggered. To optimize the performance, set it to full speed for a couple of hours and switch back to low speed to maintain the room air quality standard. Also, run your air purifier daily or as while as possible to be done to ensure the air is always clean and fresh every time you come back home.


So the most classic solution would be to run your air purifier 24 hours a day. Although, this could result in overly high costs. Not to mention, it will also wear out the filters and the machine itself. Production rate means the amount of air the device can spotless in an hour. An average unit should have a production rate of about six air changes an hour. With these statistics, you could run your air purifier for about 10-12 hours a day. Air purifiers have various built-in qualities with some ability to best when your indoor air is clean and when it has contaminants that need cleaning. If yours does not have an air standard strainer, you must think about how long you should leave the purifier running. It is secure to run your air purifier all the time since the units are built to run repeatedly without any risk of lack o success or destruction. Even when you go from the house, leave the unit running so that you can come home to clean penetrable air. Indoor air gets fast infected, so turning the air purifier on and off does not get rid of contaminants effectively.

On average, your air purifier would take 30 minutes to 2 hours to purify the air in a room. You should notice a difference in the room air quality after 20 minutes with a running air purifier. In organization for an air purifier to be truly effective, it is highly dependent on the extraction rate (air changes per hour), model type, and the room size that needs purifying. The removal rate is a figure of how much air can be clean from a room in an hour. For example, a HEPA air cleaner running at four air changes per hour (15 minutes one charge) would only take half the time to clean the air compared with an air cleaner running at two air changes per hour. Place and climate also play a big factor in how quickly an air purifier will work. There are more pollutants like pollen during the summer. Thus, an extended period of time is needed for an air purifier to clean the air. Lastly, the air cleaner must also have enough airflow capacity to fulfill the room size.


How much does it cost to run an air purifier

How much does it cost to run an air purifier?

If anyone tells us that an air purifier is very costly to run, they are lying or ignorant. We can assure you it is more energy-saving than a refrigerator or air conditioner. Additionally, we will show you the exact formula used to calculate an air purifier’s energy consumption with a few prime examples. At the end of it all, doubters will be proven wrong where it is very cheap to run an air purifier 24 hours a day. You can leave your air purifier on all night, and it will have little impact on your electricity bill. Some air purifier energy consumption is around the same as a light bulb at LOW speed (keyword: LOW). To put things into perspective, a normal television uses 70 watts of electricity per hour. A refrigerator uses 200-300 watts, and an air conditioner uses 600 watts. Washing machines are the most significant power hogger that uses 2000 watts.

 Air purifiers cost $0.12 to run per day, on average, in the US. It costs $0.85 per week, $3.69 per month, and $44.24 annually to run an air purifier. This is based on the average power consumption of 243 air purifiers, assumes 16 hours of active mode and 8 hours of standby mode per day, and uses the average price per kWh in the US (i.e., $0.15).  The most common daily running cost for an air purifier is $0.14 per day, $0.96 per week, $4.18 per month, and $50.17 per year. Air purifiers cost from $7.19 to $115.48 to run per year.

The table below summarises the average, most common, highest, and lowest running costs for air purifiers over various durations. The cost to run an air purifier increases along with room size. Per month, it costs $1.72 to run an air purifier designed for a tiny room (less than 100 sq. ft.). This cost increases to $2.50 for small spaces that are 100 to 199 sq. ft. The price rises again, to $3.34 per month, for small-medium rooms (200 to 299 sq.ft.)


How much energy does an air purifier use?

One of our FAQs is “Do air purifiers use a lot of energy?“. Here are a few things you have to keep in mind:

The first thing you need to know to check if your air purifier (or any electric device) uses a lot of energy or not is to read its usage (commonly in watts).

One unit in electricity bill equals 1 kW (1000 watts) in an hour.

More clearly, if your electric devices’ power is equal to 1 kW and you run them simultaneously for one hour, your electricity bill increases by one unit. With a typical capacity of an air purifier is about 50 watts, you could run it restlessly for 20 hours to increase one unit. Compared to the general power of a light bulb of 60 watts and a computer of 365 watts. Air purifiers, as we all know, have been one of the breakthroughs in this recent times, keeping us away from free-floating contaminations (for a relatively low price) in the atmosphere and, in turn, going to see the doctor lesser than we usually would. But with this great addition comes the air purifier electricity bill, which might be considered to be still discomforting by many air purifier consumers.

  • Air purifiers must run a lot, basically, a 24/7 operation, because they have to be as useful as possible. All air purifiers use a fan that blows, with some more powerful than the others, and the presence of a HEPA filter in most units makes sure the fan has to blow enough at high speed, thereby consuming much more energy.
  • To clarify and shed more light on the working principle of air purifiers and the amount of energy they consume, we have written this article to answer all your questions and give you an idea of how many hikes you should expect before buying that air purifier.

With a typical power of an air purifier being about 50 watts, you could run it restlessly for 20 hours to increase one unit. Compared to the general power of a light bulb of 60 watts and a computer of 365 watts. Your air purifiers are much more energy-efficient than most popular electric devices.




Can I run my air purifier 24 7?

In many cases yes, you can run an air purifier 24/7 to keep your indoor air healthy & fresh. That’s because of how air purifiers work.

Should I sleep with an air purifier on?

If you like you can sleep with an air purifier on with no problems. Air purifiers don’t cause problems as they simply remove particles from the air – they don’t add anything to it. Additionally, leaving them on all night is a good way to be sure the air is kept clean all the time. However, if you’re a light sleeper like me you may want to consider a model with a “sleep” mode feature.


Is It Costly To Run An Air Purifier All Day?

It is not costly to run an air purifier 24 hours a day compared with other home appliances. It will only cost you an estimate of $0.08 to $0.30 daily, depending on the airflow speed, power wattage, and states you’re in.


Do I Need An Air Purifier If I Have an Air conditioner To Save Energy?

​You will still need an air purifier even though you have an air conditioner in the room because both have different functionality. Air purifiers clean the air by removing pollutants. Air conditioners cool the room by regulating indoor temperature.


Final thoughts:

In addition, I would recommend cleaning the pre-filter regularly, changing the filter periodically, and following all the tips I mentioned earlier, as this will reduce your electricity consumption and increase the efficiency of the device. Please note that we only covered a few best-sellers in this article and the list is not exhaustive. Also please note that all electricity costs are based on the UK average rate of 18.54p/kWh (December 2019 tariff) Please feel free to comment below or email us with any questions you may have, thanks for reading!
