Do Air Purifiers Need To Be On All The Time?

You might be wondering whether air purifiers need to be on all the time. You may have seen a lot of conflicting information, even from reputable sources. In fact, the answer can vary depending on what type of room you're in, and what you're trying to improve with an air purifier.

That's not too surprising; there are many factors that affect what an air purifier needs to do for your environment and personal preferences.

If you're in a "sick room" (e.g., a room with frequent illness, or one that has been occupied by a pet/child for very long periods of time), it might be necessary to have an air purifier running all the time to make the room healthy once again. However, if you're in an office or home office, with no potential illness and no livestock, normal air cleaning may be sufficient.

Should I run my air purifier 24 7?

Leaving your air purifier on all the time does have some benefits, but also some drawbacks.

Benefits

Healthier air throughout your home/office: Even if you're in good health, it serves to have a cleaner environment. Keeping your air purifier on 24/7 can help with that – especially if you are sleeping with your windows closed, or are particularly sensitive to chemical smells/particles in the air.

Quieter operation: An air purifier left on overnight or during parts of the day when you aren't at home won't need to work as hard to filter the same amount of dust and other particles out of the air. This can make for a quieter operating unit.

No need to "charge" the unit: If you leave it on all the time, there's no need to remember to plug it in every night and every morning. (Though, of course, many modern air purifiers can be plugged into a standard wall outlet, so there's no need for those either.)

Drawbacks

Cost: It can get expensive to continuously run an air purifier throughout your home/office all day (especially if you're just one person). Air purifiers with UV lights are often more expensive up front because they consume more energy to run. The upfront cost of a high-end air purifier will get higher over time with this type of usage as well.

Lack of movement: If you have a unit that is designed to move around the room for maximum efficiency, it won't be able to do that all day.

Noise: It can get noisy if you leave your air purifier on continuously, especially running at a higher fan speed setting and/or with a special feature like UV lights. This may not be a problem if you're in an office environment, where the noise may be normal, but it could be bothersome if you're sleeping in the same room.

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

Thirty minutes to two hours is how long it takes to properly clean a room with an air purifier. Given the larger particles that are found in house dust, this can vary depending on the type of household you live in and the particle count, as well as how dirty or dusty your home/office is to start.

If you have a high-end air purifier with HEPA filters, it can take even longer than that for them to remove all of the normal particles that you normally come across.

Is it OK to leave air purifier on all night?

Yes, it is okay to leave the air purifier on all night, but it's unnecessary to run it all night if you are sleeping clean room.

What does air purifier do?

Air pollution is the reported number of deaths caused by unhealthy air quality. Air pollution is a complex mixture of many different sources, including long-range transport of pollutants from distant points in the atmosphere, local industrial and agricultural sources, and man-made emissions.

Most people experience little more than an occasional throat cough when respirators are fired up at factories or other locations. However, most people can experience serious health effects from even low levels of air pollution, ranging from headaches and fatigue to aggravated asthma.

Does air purifiers use a lot of electricity?

No. In fact, most air purifiers use far less electricity than a standard household light bulb. This is more than half of the amount consumed by a standard incandescent light bulb. Other large, more efficient air cleaners use even less power if you choose to use their optimum features such as purified air mode, or if you choose to leave them off all day and night.

Can I run my air purifier with the windows open?

The answer is "yes". This is a common practice with most air purifiers. You can run your air purifier with the windows open or closed, as long as the unit continues to draw air into itself.

Do air purifiers make noise?

Yes, some air purifiers make noise when they are running. If the noise bothers you, you can either turn it off or reduce the fan speed. You can also buy air purifiers that make almost no noise.

What are the pros and cons of an air purifier?

Pros

Clean and healthy air: A basic variable-speed air purifier can provide a natural, disease-proof environment by removing particles, odors, and germs from the air. Thus, it ensures that you breathe in fresh air rather than unhealthy air.

Cost-effective: An air purifier can be an inexpensive way of improving your health and well-being, without resorting to expensive medical bills. It can also save you money in the long run if you plan on using it for years. Investing in a high-end air purifier will also save you money in the long run because of their higher energy efficiency and effectiveness.

Quicker results: Some air purifiers capture airborne particles immediately, making your room (and even your home) cleaner and healthier right away.

Advance features: Some air purifiers come with advanced features such as UV lights, which are useful if you live in areas where there are radon levels or other airborne particles that need to be taken out of the air.

Cons

High up-front cost: The cost of getting an air purifier can be expensive up front; however, many models have a warranty that covers any defects for up to three years after you purchase it. That can make up for the cost of an air purifier.

Technical know-how: If you plan on purchasing a more complex air purifier, you may need to learn a few technical terms and how to perform certain functions. However, most higher-end models are pretty easy to use.

Are air purifiers a waste of money?

No . Many health professionals recommend getting an air purifier if you want to breathe in clean, healthy air. If you've tried to solve your home's bad air quality without success, not only should you consider buying air purifiers, but also installing better ventilation when possible. That is one of the best ways of getting rid of unwanted particles and odors from the inside of your home or office.

Conclusion

Air purifiers are an incredibly effective way of cleaning the air. This is especially true if you have a house full of pets as they are particularly useful in getting rid of pet dander, pollen, mold, and dust mites. They work by creating negative ions which attach themselves to common particles in the air (dust, pollen, etc.) and drag it out of the air.

There are also other forms of airborne particles that can cause harm to your health and make you feel sick. These include smog, cigarette smoke, pollutants from cars/sources such as coal burning power plants or gas stations. An air purifier is a great way to reduce these types of particles as well.
