How Often Should I Run My Air Purifier?

Last updated on October 8th, 2022

How often should you run your air purifier? The answer is different for every person, as the amount of time spent indoors will vary. However, it’s important to note that excessive indoor pollutants can be just as dangerous as those outside.

If you spend more than 8 hours a day inside and/or have asthma or allergies, then it could be necessary to run your air purifier from 2-4 hours per day. For others who only spend 4-8 hours per day in their home or office, running an air purifier for 1-2 hours each day may suffice.

As a general rule, you should run your air purifier for at least 15 minutes before the first person enters the room. This will give it time to cycle through its entire filter life and remove contaminants from both inside and outside of the home.

The timer on many models can be adjusted so that it runs as often or infrequently as desired. For example, if you are only in one area (such as an office) all day long then setting it up to turn off after two hours may save electricity costs without sacrificing performance too much. If, however, you want maximum protection throughout your house or business space then running 24/seven is recommended.

Can I run my air purifier all the time?

Before answering this question, it’s important to understand the difference between running a purifier 24/7 and having one always on.

A continuously running air purifier is constantly drawing in dirty outdoor air through its ventilation system while simultaneously blowing out filtered indoor air. This means that they need more maintenance than those with an intermittent timer setting because their filters will wear down faster. For this reason, we recommend running air purifier all the time only for very large homes or offices that have multiple people living or working there all day long.

If you’re just needing protection from occasional allergens then an intermittently activated purifier may be enough for your needs as well as save some money on electricity costs!

How Long Do I Run Air Purifier?

It is a good idea to run your air purifier continuously during allergy season when pollen and other allergens are making it difficult for you or those in your home.  In the winter, if you have an intermittent setting that kicks on every day at noon for four hours then running it all of the time may not be necessary as long as any windows are closed so that fresh outside air can’t seep inside. You’ll want to make sure there’s enough ventilation because otherwise mold will grow easily without proper circulation.

As a general rule, you’ll want to run your air purifier for at least four hours a day in the winter, and during warmer months you may need to run it for up to eight hours a day.

Can I Run Air Purifier with the Windows Open?

If you decided to run your air purifier with the windows open, you’ll want to make sure it’s set up in a location where there is natural ventilation.

In order for an air purifier to work properly and efficiently without getting clogged or overheating, it needs fresh incoming air from outside – which means any windows should be closed during use.

You will also need to clean out the filter regularly because of all the dust coming inside that may have made its way through tiny gaps around windowpanes (or even vents). As long as you are doing this on a regular basis then running an air purifier with the windows open shouldn’t cause too much concern. If not, then mold could grow quickly and pollution levels would rise rapidly.

Can I run my air purifier 24/7?

Yes, as I stated before, if you are running the air purifier with clean fresh-air coming in at all times then it will not get clogged and will not overheat.

This also depends on how long they can last on a single filter without needing replacement.

But the only time I would recommend running an air purifier 24/7 is if someone has asthma or allergies to dust mites, pollen, pet dander, etc., because they need clean dry-air all day long even when asleep.

How much does air purifier cost to run?

It will cost you between $70 and $120 each year ($6-10 per month) if it runs 24 hours per day, depending on how much electricity it consumes. They usually use about 50 watts of power per hour.

Use Air Purifier Electricity Consumption Calculator to figure out how much electricity an air purifier would use per day, month or year.

The best way to determine how much do air purifiers cost to run is by finding out what your current electric bill is for each hour you are running the machine in 24 hours (i.e., if you had an electric bill that was around 400 kWhs per month but used half of one hour during one day then your monthly cost would be 200 kWh). You’ll want to multiply that number by 20-30% more than normal every time you turn on the purifier.

Do air purifiers need to run all the time?

If you want to have fresher air all the time, then you can run your purifier 24/7.

A lot of people think that an air purifier should be running constantly to ward off bacteria in their home or office building. This is simply a myth; truthfully there are so many other things that need to happen for these types of bacteria to reproduce, it’s just impossible for any type of filter or HEPA vacuum cleaner on its own will remove them completely from the environment.

Do I run an air purifier all day? No, I don’t. I use Nuwave OxyPure air purifier (my review is available here) only for 4-6 hours per day, sometimes more, depending on a season and weather conditions.

I recommend running your air purifier for at least 15 minutes every day. This will help ensure that dust, pollen and other particles are always being removed from the environment on a regular basis. Running it in short bursts throughout the year is more than enough to keep dirt down so you’ll have cleaner indoor air all year long!

You should also change or clean your filter once per month (or per year, depending on a air purifier you’re using – my Nuwave OxyPure utilizing filters that last much longer) as this will reduce any bacteria buildup inside of your unit which can lead to poor quality breathing conditions.
