How Long Should An Air Purifier Work?

Last Updated on March 29, 2024

Yes, you can’t expect air purifiers to last forever. Air purifiers trap dust, pollen, pet hair, and germs flying around your home. Day by day, the particles build up a layer and decrease the purifier’s lifespan. Now the question is, how long should an air purifier work? 

The lifespan of an air purifier depends on certain aspects, such as the air pollution range around your home, the requirement of units a day, and the maintenance you provide. However, on average, an air purifier should work for 2 to 5 years. 

However, this duration is only for the machine, not the filters. Filters last 6-12 months, and carbon pre-fibers should be changed every three months.  

There is still too much information regarding air purifiers to shake a stick at. Take it easy; our article will help you to get through it! 

How Long to Run Air Purifier?

You can use it for as long as you want. But if you want effective results, at least turn the machine on for 7-8 hours daily (no harm if you keep it on 24/7). This way, you can keep your windows and doors open if needed without stressing about harmful particles. 

Although, if you’re too stressed with the electricity bills, keeping it on for the least amount of time will also do a pretty decent job. So, the duration depends on your necessities and preferences, actually. 

Can You Leave an Air Purifier on All Night?

You certainly can. Air purifiers are one of the safest machines. Just make sure you clean the filter once a month, as it traps a thick layer of dust, allergens, and other harmful particles. And instead of turning the purifier off at night, it would be best if you keep it on. 

Sleeping with the cleanest air is all we want, right? So, here’s your elbow room; the purifier will keep your room fresher and safer than ever when you sleep. If you turn it off, your room will potentially be filled with dust and germs again after a few hours. And it is never healthy to spend lofty sleeping hours in untidy air. 

How Long Should You Run an Air Purifier?

Air purifiers are built to be turned on all day and night. So, if possible, you should leave your air filter on all day long. The longer you keep this on, the cleaner and fresher the air around your home will be. 

Moreover, there are no possible drawbacks to leaving your air purifier on 24/7. If you purchase an electricity-conscious air purifier, it won’t stretch much of your electricity bills too. This is because these purifiers are built in a way that consumes less electricity. 

Small-sized air purifiers won’t use more than 50 watts (per hour) of electricity. If you install the medium ones, the maximum bid would be 100 watts per hour (which won’t seriously harm your bills).

So it’s very cheap to run an air purifier. Leading air purifiers don’t charge over $10 worth of electricity per month, even if you run it 24/7. However, different areas have different electricity rates, so it’s recommended that you know the rate of your region.
