If you require a humidifier and do not want to read the entire article, below are the recommended items from the article.  (Low, Medium and High Price)

Part I: What is an Air Purifier with UV Light?

UV light stands for Ultraviolet radiation, which operates at a wavelength shorter than visible light and longer than X-rays, but harmless to humans and other animals without protection. Ultraviolet rays possess great abilities to remove bacteria and viruses from the air. In addition, for general cleaning, UV technology can be used to sterilize the air of smells, odors and mildew.

By incorporating ultraviolet technology into air purifiers, indoor pollutants that are invisible to the naked eye or our senses are effectively controlled and removed from the environment. Because these pollutants exist in micro-particle form (viruses and mold spores), it is impossible to achieve complete eradication using only one type of filter.

However, UV has a long wavelength that is effective against these particles which allows a combination of HEPA filtration plus Ultra Violet light to virtually eliminate them. You can imagine the effectiveness of this technology when you think about how much viruses are spread via hand-to-hand contact.

Part II: Diseases that can be treated by UV Light

Legionnaires disease and Tuberculosis are both illnesses that are treated in a hospital setting using Ultraviolet light. However, air purifiers with UV light can be used to treat the same diseases at home. It is important to note that these two diseases and conditions are only treated using UV light when there is active infection and not as preventive measures, although convincing arguments could be made for doing so as well.

Tuberculosis (TB) has been around for thousands of years, infecting and killing hundreds of millions of people each year. Although TB is curable, there are still 10 million people who are infected by the disease and 1.7 million who die from TB.

Treatment for TB includes a combination of antibiotics and UV light therapy (this is where UV light comes in). The treatment takes place in a machine called an "Intensivist", which uses intense levels of ultraviolet light to kill Tuberculosis bacteria that reside deep within the lungs. The Intensivist unit emits this concentrated dose of ultraviolet radiation for many hours per day for up to three months.

Legionnaires' disease is a type of pneumonia caused by the Legionella bacterium, which has become one of the leading causes of death from infectious diseases in America today.

Part III: Why choose an Air Purifier with Uv Light?

There are three main reasons why you may want to choose an Air Purifier with UV Light:

1. Better Air Quality

A regular home air purifier can only filter a limited range of pollutants. However, UV light technology is able to eliminate the harmful particles that cause indoor air pollution and other diseases, such as Legionnaire's disease and Tuberculosis. Using UV light technology in conjunction with your standard home air cleaner will ensure that you are improving your indoor environment and removing harmful bacteria and viruses from the air.

2. Odor Removal

Air purifiers with UV light are ideal for removing unpleasant odors out of the air. When it comes to removing odors, most people think of charcoal filters, which is a very effective method. However, UV light technology also has the ability to remove odors from the air and in some cases it is even more effective than charcoal. The reason for this is that charcoal filters remove pollutants from the air by literally trapping them on their surface. However, these "impurities" can still be released back into the air after they are trapped.

3. Sanitizing and Germicidal capabilities

Germicidal capabilities are a vital part of an effective home air purifier that removes harmful bacteria and viruses from your home environment. UV light is one of the most effective methods of controlling these particulates.

Part IV: Benefits of Air Purifiers with UV Light

In addition to the reasons above, there are many other benefits that you will receive when using an Air Purifier with UV Light. These include enhanced health, a healthier environment and longer-lasting filters. Some people might also choose to use their air purifier as extra place for collecting dust or pet particles, which can be swept away by the UV light technology.

You can even add a UV light to your space sensor to ensure that pathogens in your house do not seep outside into public areas when you open windows or doorways. Air Purifiers with UV Light are extremely easy to use with most users taking only a few minutes to get it up and running.

In addition, the air quality in your home is simply unbeatable due to the elimination of harmful microorganisms from the air.

About UV light On Air Purifiers

Are air purifiers with UV light safe?

While the UV light technology is essentially safe for all members of your household, there are individuals who should not use the technology. This includes people with photosensitive skin or eyes, those undergoing cancer treatment or using skin creams that contain SPF. The reason for this is that the exposure to UV light may cause severe burns and adverse effects. These issues are very rare however, anyone unsure of whether they should use UV light should contact their doctor.

Which is better HEPA or UV light?

Many homeowners will try to decide between HEPA or UV when purchasing a new air purifier. While they both have their own benefits, UV light technology is more advantageous when it comes to killing germs and bacteria in the environment. This is because UV light has the ability to penetrate into areas that would be difficult for a HEPA filter, such as cracks or crevices in your home.

When should I use UV light on air purifier?

You should use your air purifier with UV light when you need to remove microorganisms from the air or to improve the air quality in your home. Some people choose to take advantage of this technology on a daily basis, especially when there is a low level of virus and bacteria present in the air. Other people will only use this technology when they experience an adverse health issue.

These will protect your home from harmful bacteria and organisms.

What does UV light do on air purifier?

UV light on air purifiers eliminates germs and microorganisms on the filter, HEPA filter, and other parts of the unit. Microorganisms are trapped on the surfaces of these parts so that they cannot spread through your home.

UV light on air purifiers also neutralizes gases such as carbon dioxide and nitrogen so that the air in your home is thought to be more pure. Air purifiers with UV lights will even help keep your home dry by removing moisture from the air and preventing mold growth. Even though they do not produce a noticeable amount of vapors like some other brands of air purifiers, UV light units do not use toxic chemicals such as formaldehyde or benzene.

Are UV air purifiers better?

UV lights on air purifiers are simply more effective and powerful than regular HEPA filters. They are also more effective at removing unwanted odors, bacteria, and viruses that can be harmful to your health.

Air purifiers with UV light can make a significant difference in the quality of air in your home. The UV rays kill germs, mold, mildew and other unwanted microorganisms that cause odors or allergies. Most homeowners who use air purifiers with UV lights notice an improvement in their health over time as well as a cleaner home environment. There is also less risk of spreading harmful bacteria through your house if you have a UV air purifier instead of just one that filters the air.

Do UV lights improve air quality?

Yes, air quality will undoubtedly be improved by using an air purifier with UV lights. Many people have allergies and respiratory problems such as asthma, and the air purifiers with UV lights will remove pollen, other allergens and bacteria from the air.

According to Wisconsin Department of Natural Resources, "Many diseases are spread by microbes in the environment. For example, being around someone who smokes or has a cold may lead to your developing one of these diseases. The same is true for being around someone who has a pet bird that isn't properly cared for."

This is why it is very important that you use an air purifier with UV light at home to help prevent spreading harmful germs through your environment.

Why does it smell after using a UV light?

If your air purifier has a UV light, it is more than likely that you will notice a slight odor after using the purifier for a period of time. This is perfectly normal because the UV light must kill the germs on the filter and other parts.

This will neutralize any harmful bacteria or viruses on the surface and will result in an odor similar to that of burning rubber. Once you change the filter, this odor will fade away. In addition, this smell is not harmful to your health but some people find it unpleasant.

Do portable UV sanitizers really work?

The answer to this question is yes! Portable UV sanitizers are very effective at killing germs and organisms in the area. One of the reasons that they are so popular is that they eliminate odor from the area and keep your environment hygienic.

In addition, it's incredibly easy to use and just requires you to push a button for a few minutes each day before you leave your home. You'll notice an improvement in your health after just one use because of the increased air quality in your home or vehicle.

Is UV light for AC worth it?

Of course, YES, an AC Light will make a huge difference in the air quality of your home. UV lights on AC units are extremely powerful and effective at killing bacteria and viruses, mold spores, mold growth in carpet, etc.

It will actually improve the quality of air in your home as well as increase the life of your AC unit by up to 68% which can be great for everyone who spends time indoors while their AC is running.

Is UV light safe for eyes?

It is important to remember not to stare directly into UV light. Although the light is not harmful to your skin, you can make yourself feel sick if you stare directly at the light. If you are using an air purifier with a UV light and you have young children, make sure that they stay away from the light when it is being used so that they do not get a headache or a burning sensation in their eyes.

Better Over All Heath

When you get a UV air purifier, it will eliminate odors from unwanted microorganisms in the air as well as neutralize harmful gases such as carbon dioxide, nitrogen and make your home or vehicle more humid. There is also less risk of spreading harmful bacteria through your home if you have a UV air purifier instead of just one that filters the air.

UV light on air purifiers will help keep you healthy by providing a germ-free environment. It also prevents the spread of bacteria and diseases from room to room after you move around. UV light on air purifiers is simply more effective at removing unwanted odors, germs and viruses that can be harmful to your health than other brands of air purifiers.


When you use an air purifier with a UV light, you are benefiting your health as well as the environment. Air purifiers with UV lights are more effective at killing bacteria and viruses than regular HEPA filters. In addition, they remove moisture from the air and prevent mold growth so that your home is less likely to be affected by musty odors in the air.

It is important to know the difference between an ionizer and a UV air purifier before you buy a new device. UV light used in air purifiers is one of the most effective ways to kill bacteria and mold spores that can cause allergies or illnesses.

Likewise, the fact that many air purifiers only have regular HEPA filters can be a drawback. The ultraviolet light in the purifier makes up for the lack of filtration by killing germs and viruses in the air which could spread infections.

If you enjoy cleaning your home and want it to be more sanitary, try an air purifier with a UV light. Whether you are using it on your carpet or AC unit, you will notice an improvement in the quality of your home's air and health and also reduce allergens in your environment as well as its odors.

Other Questions

Which UV light is most dangerous?

The most dangerous UV light in the air is the direct rays of sunlight. It has been known that some people have experienced severe eye damage from simply looking directly at UV lights. Direct exposure to sunlight also has the ability to burn skin and cause severe eye damage.

Some people choose to use an ultraviolet air purifier anywhere in their home, but there are many places where it is not necessary. For example, unlike an air purifier that needs to be connected into an HVAC system, a UV light can be used with any other type of home system.

Is UV light harmful to humans?

UV light is not harmful to humans. However, UV lights should be avoided if you are likely to be exposed to UV rays in the sun. UV lights should also be avoided if the sunlight is intense or directly overhead such as during the middle of the day.

UV light causes eye damage when your eyes are exposed directly to sunlight. UV light products can create exposures that differ from those produced by direct sunlight. As with any exposure, prolonged exposure can cause irritation of skin and eye tissues. The intensity and duration of exposure may vary from manufacturer to manufacturer, so it is important to read and follow all directions on any accessory or equipment packaging before use for best results.

Does UV light kill bacteria in shoes

Yes, it kills bacteria in shoes and clothes. UV light is good for keeping pet urine stains off of carpets. It also effectively kills fungus and mold spores that get onto your clothes from the outside environment. In addition, over time it can even help to eliminate bacteria from the fabrics themselves, helping to keep you healthy for life.

Does UV light work on bed bugs?

UV light does not work on bedbugs because insects are not affected by this kind of radiation. However, there are other ways to get rid of these insects that you will find in your home or business, such as using rapid heat or freezing them with a liquid nitrogen fogger.
