What kind of air purifier did you just buy for your house? Purifiers are excellent for keeping the air in your home fresh and clean.

However, you may be unsure of how to utilise it to its full potential. How long do you leave it running for? Is there a way to adjust the settings on my air purifier? What if I don’t use it for the rest of the day? Is it possible for me to do so?

how long should you run an air purifier

Make sure your air purifier is running all day long if you can. Your home’s air will be purified of dust, pollen, smoke, and other unpleasant odours thanks to this device. The more time you give it, the better the air quality will be. Keeping your air purifier on 24 hours a day does not have any obvious drawbacks. They’re designed to be left on 24 hours a day, seven days a week.

How long should I run my air purifier?

Most of the time. Dust and airborne particles circulate throughout the day, so running your air purifier continuously will give you the best results. Keep it running 24 hours a day for best results. You won’t have to deal with allergies like a runny nose, a runny nose, red eyes, a headache, or itchiness if you have continual clean air that is free of airborne allergens.

Even if you’re not at home, you may leave your air purifier running all the time. Without overheating, a HEPA air purifier can safely and effectively remove allergens such as pet dander and dust, as well as hair, lint and mould. There are more advanced air purifiers on the market that can automatically turn on when the air inside the house is harmful and shut off if it is healthy.

The air purifier must not emit dangerous ozone, often known as an ozone generator, and the filters must be replaced or cleaned on a regular basis. The air purifier will have to work harder to clear the air if the HEPA/carbon filters are unclean.

Whether you’re a light sleeper or not, you should use an air purifier seven days a week to help you get a better night’s sleep. The Asthma and Allergy Foundation of America (AAFA) states that an air purifier can help you sleep better by minimising irritation to your eyes, skin, and lungs. Invest in a silent air purifier for your bedroom and keep it near your bed or nightstand for a restful night’s sleep. When you’re closer to your breathing zone, the clean air travels a shorter distance to reach you.

Is it safe to leave an air purifier on all day?

Leaving your air purifier on all day is safe. However, you must clean the filters at least once a month. If the filters aren’t cleaned on a regular basis, they can pose a risk to those with allergies and other sensitivities.

Should I sleep with my air purifier on?

If you want the purest air possible, you should sleep with your air purifier on. After a few hours of not using your air purifier, the air will begin to become polluted again. Because you spend a significant portion of your waking hours breathing in and out of a pillow, keeping your bedroom air clean is critical to your health.

Do air purifier settings make a difference when running it?

They do, for sure. Most air purifiers include a variety of fan speeds that may be changed in exchange for consuming more power and creating a louder sound. It’s best to leave the air purifier running at its maximum setting for as long as possible if you only have a few hours a day to clean the air in your home. Note that most air purifiers’ maximum settings are too loud to hold a conference in the same space.

How much electricity does an air purifier use?

There are small and medium air purifiers, both of which consume under 100 watts of electricity.

You can run your air purifier at a very low cost. In most cases, running a 24-hour air purifier costs between $5 and $10 a month. A quick Google search will provide you with your state’s electricity rate.

How long does it take for an air purifier to clean a room?

The size of the room and the wattage of the air conditioner will have a significant impact on this. When it comes to determining how effective an air purifier is, it’s important to keep in mind that the higher the CADR, the more successful the purifier will be. When it comes to airflow through the filters and model efficiency, CADR is a popular grade because it considers both factors.

However, an average-sized room can be cleaned thoroughly by an air purifier in at least a few hours.

Should my air purifier be on the floor?

A counter or bedside table is ideal for your air purifier. Faster than air purifiers on the floor, it will remove impurities from the ceiling. Keeping it on a counter isn’t necessary, but it will improve the air quality a bit more.

Can I set a timer for my air purifier?

Yes, many air purifiers today have timers that let you turn them on and off at certain times of the day. When planning when to use your purifier, that can save you a lot of time. Most of the time, you can set it to run while you’re away, and when you get home, the air will be cleaner.


Running an air cleaner for just a few hours doesn’t guarantee that you’ll breathe clean air for the rest of the day. In reality, airborne contaminants do not stop, and neither should an air purifier that is designed to work nonstop. As a result, don’t allow your hard-earned money go to waste by leaving the air cleaner unused. Allow the air purifier to do its job and deliver clean, fresh air as intended.
