14 Benefits of an Air Purifier – Are Air Purifiers Worth It?

In an era of all kinds of pollution, we need the most updated technology to survive. An air purifier is one of the most modern technologies to combat air pollution. Everyone knows the consequences of air pollution. However, most of us don’t know the benefits of an air purifier. There are many benefits of an air purifier. It can help you in any commercial or residential environment. Air purifiers are also perfect for offices, schools, and hospitals.

Are Air Purifiers Worth It?

Absolutely. Let’s look at some of the statistics to know why. According to the Environmental Protection Agency (EPA), indoor air is more polluted than outdoor air because of less air circulation. It may sound strange, but it’s true. Moreover, indoor pollutants have a 2 to 5 percent higher concentration than outdoor pollutants. The higher the concentration of the pollutants, the more harmful it is. Irritation of the eyes, nose, and throat happens because of these pollutants. It also causes headaches, dizziness, fatigue, respiratory diseases, heart disease, and cancer. Now, with a little investment, if you could get rid of the impacts of pollution, wouldn’t that be great?

Americans spend almost 90 percent of their time indoors. Young people, older adults, and people with heart and lung disease spend more time indoors. If the indoor air quality is not fresh and healthy, you can imagine what can happen to your lungs and respiratory system. By staying indoors most of the time, we are exposed to inhale all the pollutants through breathing. And the consequences are deadly. So, I would say spending on an air purifier is a smart decision.

Are Air Purifiers a Waste of Money?

Not at all. Rather, buying an air purifier is money well spent. Investing money in an air purifier is like investing in your health. Your indoor air quality can impact your health in many ways. Some impacts can be irreparable like – lung cancer, asthma, or heart disease. Most of us think that indoor air is already fresh and purified. But that’s not true. Indoor air is more polluted than outdoor air.

Now, what are the sources of indoor air pollution? Some pollutants are produced inside, and some come from the outside. Indoor sources include – tobacco, fireplace, wood and coal heating, cleaning supplies, paints, radon, mold, and pet dander. Outdoor air pollutants enter the buildings through open doors, open windows, and cracks in structures. Moreover, outdoor climate, weather conditions, air exchange rates, and occupant behavior also affect indoor air quality. 

The good news is air purifiers can solve these problems with 99 percent efficiency. There are also other health benefits of an air purifier. So, air purifiers are not at all a waste of money.

Benefits of an Air Purifier

What Does an Air Purifier Do?

Air purifiers have internal fans that absorb the air in your home through a series of filters and remove harmful airborne particles such as – dust, bacteria, pollen, etc. After purifying the air, it releases the air back into your room. Throughout the day, an air purifier performs this task several times and keeps the indoor air fresh. Watch this video to know exactly how air purifiers work.

Benefits of an Air Purifier

There are many health benefits of an air purifier. Some of them are very crucial to our health. To be honest, the level of air pollution in the city is life-threatening. Because of the massive industrial revolution, air quality in every city is miserable. Pure fresh air has become a rarity. However, Air purifiers can help us to breathe fresh air in our homes.

Eliminates Triggers of Asthma Attacks

According to the Centers for Disease Control and Prevention (CDC), 1 in 13 people has asthma. You can find most asthma triggers in your home, such as – dirt, dust, household cleaners, air fresheners, smoke from cooking, cosmetics, perfumes, and hairsprays. Pet dander, pollen, and dust mites irritate asthma patients’ airways and cause difficulty breathing.

You can vacuum your bed, carpet, and floors to get rid of these pollutants. Still, some of them remain suspended in the air, and they can seriously increase your asthma attacks. Most air purifiers capture these pollutants so you can breathe clean air. HEPA filters, with their multi-layered meshes, can trap pollen, dust mites, and pet dander. In addition, the meshes are thinner than strands of hair, and they can effectively purify indoor air. An air purifier that removes microscopic contaminants is ideal for asthma patients. Along with using an air purifier, you should also increase airflow in your home for the best result.

Removes Allergens

There are many allergens in our home, such as – pollen, tobacco smoke, dust mites, and dander. When pets scratch themselves, they spread a lot of hair and dander that keeps circulating in the air. Moreover, pollen particles flow in with the breeze through open windows, or they stick to your clothes when you are outside. 

Breathing in tobacco smoke, pollen, dust, and dander cause our body to produce IgE. IgE is responsible for allergic reactions. To get rid of the allergens, we should use an air purifier. With multi-layered filters, air purifiers can eliminate allergens and produce clean air for us.

Traps Tobacco and Cigarette Smoke

The smoke of tobacco causes pulmonary diseases, bronchitis, dementia, and heart disease. Ear infections, asthma, and pneumonia are also the side effects of cigarette smoke. In addition, second-hand smoke is deadly for children and elderly people because of their poor respiratory systems. With HEPA filters and activated carbon, air purifiers can remove smoke from your room. When you install an air purifier – odor, gases, and smoke pass through the activated carbon and get absorbed in it. Consequently, you breathe the most purified air.

Reduces Harmful Chemicals

Nitrogen dioxide and carbon monoxide are found in high motor vehicle traffic areas. These gases may come into the house and cause dementia or Alzheimer’s disease in the long run. Moreover, regular household cleaners contain ammonia and chlorine. Daily exposure to these chemicals can lead to a tumor, cancer, or neurological disorders. Air purifiers can clean these chemicals with activated carbon and save you from potential health issues. The carbon filtering process traps the chemicals and recycles fresh air back to the room.

Neutralizes Unpleasant Odors and Eliminates VOC 

Volatile organic compounds (VOC) are chemicals found in paints, furniture coatings, aerosol sprays, clothes from dry cleaners, stored fuels, and air fresheners. The substances have a strong smell that can cause nausea and breathlessness. You can tell whether there is VOC in your home if you have watering eyes, nausea, difficulty breathing, and a burning or choking sensation in your throat. Air purifiers save you by trapping gases with their multi-layered filters. It also absorbs the smoke and odor of cooking oil or spices. Consequently, you won’t be disturbed by unpleasant smells or embarrassed in front of your guests.

Reduces the Chances of Airborne Diseases

Tiny pathogens floating in the air are the culprit behind the common cold and flu. Airborne diseases are dangerous because they are contagious and can affect every family member. HEPA filters in air purifiers efficiently capture bacteria and viruses. This filtering process saves you from unwanted colds and flu. An air purifier is a must for people with a weaker immune system – like children or senior citizens.

Improves Sleep

Air purifiers capture all the allergens, bacteria, dust mites, and fungi, as a result, improve the air quality. This improved air quality helps you to sleep better. Air purifiers also make a soft and soothing sound that hums you to sleep. The sound that air purifiers make is like the ocean waves or the calming winds on a mountaintop. These peaceful sounds will help you to fall asleep.

Eliminates Radon Gas 

Radon is a colorless and odorless gas that emits from building materials like rocks, soil, and granite. You can also find it in homes, offices, and schools. It enters through cracks in the floors and walls, construction joints, or gaps around service pipes, electrical wires, and sump pits. Radon gas damages the cell linings of the lungs and leads to lung cancer. Using an air purifier is the easiest way to remove radon gas. An air purifier sucks the gas into its unit and purifies the air for you. HEPA filters and activated carbon filters can trap radon gas and protect you from its harmful effects.

Extracts Airborne Asbestos Particles 

Asbestos is an odorless and tasteless mineral. This heat-resistant mineral is made of durable fibers. In the past, asbestos was used heavily in building materials and everyday products. But later, we came to know that it causes lung cancer and tissue scarring. Swelling in the neck or face, loss of appetite, and difficulty swallowing are some symptoms of asbestosis. To completely get rid of asbestos from your home, you need professional help. Asbestos particles will flow in the air during the removal process. An air purifier can effectively capture the floating asbestos particles. Use HEPA air purifiers to save yourself from the harmful effects of asbestos. 

Increases Life Expectancy 

Harmful airborne particles can impact our brain and cognitive function. Moreover, indoor air pollution weakens cardiac, respiratory, and even neurological systems. Pollutants can also accumulate in our bodies and seriously damage our most vital organs. By tackling these fatal indoor pollutants, an air purifier can increase our life expectancy in the long run.

Removes Outside Pollutants 

Allergic diseases are more common in modern and urban cities. People living in modern cities near highways are more likely to have allergies and asthma. Because the pollutants near these locations include ozone, sulfur dioxide, nitrogen dioxide, and diesel exhaust particles. All of these can be hazardous to those with allergies and asthma. To stop outdoor pollution, you should use an air purifier. You can also create proper ventilation and airflow in your house. But that’s not enough. Along with those, you must use an air purifier.

Reduces Carbon Dioxide Levels in Your Home

We all know carbon dioxide is harmful to us. That’s why we release it every time we inhale oxygen. When we are in a confined space like our home, there is less scope of oxygen circulation. Lack of oxygen circulation increases the amount of carbon dioxide in the air. Consuming too much carbon dioxide can cause shortness of breath, headaches, dizziness, weakness, increased heart rate, sweating, lung diseases, and even death. An air purifier with a HEPA filter can reduce carbon dioxide in the air and circulate the air in your home.

Removes Dangerous Insects 

Mosquitoes carry the germs of some deadly diseases. We know what little mosquitoes can do to our health. We use aerosol and sprays to get rid of mosquitoes. But mosquitos usually do not die from the chemicals of aerosol or insect spray. Rather, we spread toxins in the indoor air by spraying aerosols. So, in an effort to kill the mosquito, we add more toxins to the home environment. However, Air purifiers can do a much better job than aerosols to get rid of mosquitoes and other bugs. By using an air purifier, you can remove mosquitoes without making indoor air toxic. 

Lessens Contamination in Hospitals

Most of the hospitals are near freeways, and they draw in a lot of outdoor pollution. Indoor pollution in hospitals is more destructive than anywhere else. People in the hospital are close to airborne viruses and bacteria. The germs can settle on magazines, office brochures, clipboards, doorknobs, and pens. Hospitals use disinfectants, but they are not enough. Rather, they leave toxins in the air. An air purifier can effectively prevent these germs from landing on things. They also remove the toxins in the air left by the disinfectants. Air Purifiers can also be useful in operation theatres.


A small investment in an air purifier can have a big impact on your life. As mentioned above, the health benefits of an air purifier are many. It can certainly improve indoor air quality and provide us with fresh and healthy air every day.

FAQs (Frequently Asked Questions)

How Do Electric Razors Work?

So, what is the mechanism of an electric shaver? Here is the electric shaver mechanism:

There are two main parts in an electric razor to cut the hair. Those are – an ultra-thin, perforated metal foil and a set of tiny blades, also known as undercutter. The function of the perforated metal foil is to cover the oscillating blades of the shaver and to protect your skin from direct contact with the blades inside. The foil also has some tiny holes in it to trap the hair. These holes are smooth on the outside but sharp on the inside. Body hair can enter through the hole to be cut by the sharp blades inside. The set of tiny blades oscillates back and forth very quickly on the other side of the foil. When the hair enters through the metal foil, the sharp blades slice off the hair.

Types of Electric Shavers

There are two types of electric shavers. They are Rotary shavers and Foil shavers. Both of them can give you a clean shave, but a foil shaver can give you a cleaner and smoother shave than a rotary shaver. Rotary shavers are especially suitable for thick, long, and uneven hair. There is also a difference in their design, shaving process, technology, and noise level. But the basic electric shaver mechanism is the same. Both electric shavers have a thin layer of perforated foil with tiny holes that touches the skin and captures the hair. Then the fast oscillating blades cut the hair inside. The main difference between the two types of shaver is in the shaving process. A foil shaver should be used in a linear motion, and a rotary shaver should be used in a circular motion.

How Does a Rotary Shaver Work?

Rotary shavers, as the name suggests, have three or four rotating heads. Usually, they come with three heads in a triangular shape. Move a rotary razor in a circular motion so that it reaches the deep crevices and curves of your face. The circular motion pulls the facial hair into the shaver and cut them inside with the tiny blades. It is easy to maneuver around the chin and the neck with a rotary shaver. An ideal rotary shaver can get hair in all the nooks and crannies on your face. Rotary shavers are perfect for fast-growing and uneven facial hair. If you don’t have a daily shaving routine, and you shave only once or twice a week, a rotary razor will give you the best result.

How Does a Foil Shaver Work?

A foil shaver is named after the foil that covers the blade inside the shaver. The word foil refers to the thin sheets of metal that have tiny holes. In a foil shaver, a thin layer of foil covers its oscillating blades. The thin layer lifts the hair from the skin to cut it neatly. There are three or four blade options in an electric foil shaver. Four blades give you a faster and closer shave than a three blades shaver. You can move the foil shaver in a linear motion, the way you use a standard razor. There is minimal contact between the blade and the skin. As a result, it doesn’t cut or irritate your sensitive skin. If you shave every day, and you want perfection for trimming sideburns, mustache, or beard, then a foil electric shaver is the right choice for you.

Can You Cut Your Face With an Electric Razor?

It’s very unlikely if you use the shaver correctly. The blades of an electric razor do not come in direct contact with your skin. Your skin is protected from the blades by the foil, the thin layer that touches your skin. So, it’s less likely that you’ll cut your face with an electric shaver. The makers of electric razors are aware of the possibility of cutting your face with an electric shaver. That’s why they designed it in a way to protect your face.

Are Electric Shavers Bad for Skin?

Not at all. In fact, electric razors are excellent for sensitive skin. The blades of an electric shaver do not touch your skin. It is the ultra-thin layer of foil that touches and comes in direct contact with your skin. So, there is hardly any chance of skin irritation and razor cuts while shaving.

Do Electric Razors Hurt?

No. Every precaution is taken to prevent an electric razor from hurting us. It’s understandable that we think an electric shaver might hurt us. But there is no chance of an electric razor hurting us. As mentioned above, blades do not come in direct contact with your skin. Body hair is trapped through the tiny holes of the foil, and then the oscillating blades inside do their job. Don’t press the shaver too hard on your skin. And you’ll be fine.

Are Electric Shavers Worth It?

Certainly. If you are a busy person and you need to shave every day, an e-razor is highly worth it. E-razors shave faster than manual razor. You don’t need to get water, a shaving brush, shaving cream, foam, or gel to shave with an e-razor. Within a few minutes, you can get a perfect shave anywhere you want. Plus, there is less chance of skin irritation, nicks, and razor cuts with an e-razor. Shaving every day with a manual razor is bad for your skin since the blades come in direct contact with your skin. Electric razors are perfect for daily shavers in every way.

Can Electric Razors Give You a Clean Shave?

Yes. E-razors can give you a clean shave. But not as clean as a safety razor. The blades of e-razors barely touch your skin. The thin layer of foil comes between the blades and your skin. That’s why the e-razors give less clean shave than the manual safety razor. That doesn’t mean e-razors can’t give you a clean shave. They can. And the level of clean shave they give is enough for most people. The foil shavers are better to get a clean shave than the rotary shavers.


Electric razors are a testament to the fusion of technology and grooming. Armed with a deeper understanding of how they work, you can maximize your shaving experience.

This guide has taken you on a comprehensive journey through the history, types, components, and maintenance of electric razors. With this knowledge, you can achieve a closer, smoother shave while ensuring your trusted grooming companion serves you faithfully for years to come.

The next time you reach for your electric razor, you’ll do so with a newfound appreciation for the science behind that perfect, hassle-free shave.

What Temperature Should a Refrigerator Be? Fridge Temperature Guide

What Temperature Should a Refrigerator Be? Fridge Temperature Guide

Most of us are not sure about the correct refrigerator temperature. We use our superficial ideas and general assumptions to set the fridge temperature. But that’s not safe at all. Failing to maintain the right fridge temperature has serious consequences. Bacteria such as — Salmonella, E. coli., and Listeria can cause foodborne illness if you store food at the wrong temperature. 

Keeping your refrigerator at the proper temperature is a serious issue. To keep food fresh and prevent bacterial growth, chilling food at the right temp is mandatory. So, what temperature should a refrigerator be? In other words, what is the best refrigerator temperature? In this article, I’ve covered everything you need to know about maintaining your refrigerator temperature. By the end of this article, you will get all the answers regarding this crucial topic.

How Cold Should a Refrigerator Be?

We want our refrigerator to be cold, but not so cold that it freezes everything. We have a freezer section for freezing things. A refrigerator should be cold enough to prevent the growth of bacteria without freezing everything inside. Some foods like — eggs, meat, lettuce, and strawberry lose their quality when they’re frozen. Ideally, the fridge shouldn’t be too cold or too warm. Too much cold lessens food quality, and warm temperatures spoil food quickly by helping the bacteria to grow exponentially. In fact, at room temperature, bacteria can double themselves every twenty minutes. Therefore, we have to find a sweet spot in between to set the perfect temperature.

What is the Correct Temperature for a Fridge and Freezer?

The U.S. Food and Drug Administration (FDA) recommends that the correct temperature for a fridge is below 40℉ or 4℃, while the correct temperature for the freezer is 0℉ or -18℃. Bacteria grow exponentially at around 40-41℉ and most materials freeze at 32℉. So, the ideal refrigerator temperature range is 35-38℉. And the best freezer temperature range is 0-2℉ at the highest. The correct refrigerator temperature slows the growth of bacteria and keeps the food fresh. Your goal is to keep food as cold as possible without actually freezing it.

Always try to keep your refrigerator temperature range within 35-38℉. Stay away from the danger zone of over 40℉. To retain the ideal temperature of your fridge, try to open the fridge door as less as possible. When you open the fridge door, warm air rushes in the refrigerator and increases the internal temp. Therefore, don’t keep the door open for long. Avoid opening the door during a power outage.


How to Measure Refrigerator Temperature?

As mentioned above, Listeria, Salmonella, and E.coli. bacteria multiply rapidly at a warmer temperatures like 41℉. Salmonella is by far the biggest culprit of serious food poisoning cases in the United States. That’s why maintaining the correct temp is highly important. We know the safe refrigerator temperature is around 35-38℉. But the question is, how do you measure refrigerator temperature? Most of the fridges don’t display the internal temp reading. They have a manual knob to set the internal temperature. But these knobs don’t display the exact temp. It only shows a series of numbers such as 1-5 or 1-9. It’s not clear which number means what temperature.

Therefore, the best way to measure refrigerator temperature is to install a refrigerator thermometer inside the fridge. A refrigerator thermometer can display the exact temperature reading anytime — even when there is a power outage.

What Temperature Should a Refrigerator Be

Refrigerator Thermometer

A refrigerator thermometer is the most accurate way of getting a temp reading. You can place the thermometer in different parts of the fridge to test which parts of your fridge are colder than the others. Refrigerator thermometers can solve most of your fridge temp concerns. These thermometers are small, lightweight, inexpensive, and easy to install. Plus, when there is a power outage, it will continue to display the temperature in the fridge. This will help you to decide if the refrigerated food is safe to eat after a power outage. You should buy two thermometers. One for the refrigerator section. And the other one for the freezer section.

Simply put a refrigerator thermometer deep inside of your refrigerator to track your fridge temp. After placing the thermometer in your fridge, close the door, and wait for 3-5 hours to get the best read. If the temp is 40℉+, adjust your fridge’s temp setting to make things colder. When it’s in the freezing zone of below 32℉, adjust the temp control to make things warmer, and prevent food items from being frozen. On the other hand, a temp around 35-38℉ is the ideal temp. Don’t change the temp setting when your fridge temp is at that level.

For the freezer section, place the thermometer right in the middle of the stacked food items. After a few hours, check the reading. Adjust the freezer settings as necessary to get the temp in a safe range. Always try to keep the freezer temperature at around 0℉. Repeat the adjustment process until you get the ideal temperature.

Refrigerator Temperature Setting 1-5/1-7/1-9 

Most refrigerators have an unspecific and limited temperature setting. These refrigerator controls just show a series of numbers such as 1-5 or 1-7 or 1- 9. It’s not clear which number is the coldest and which is the warmest. This numbered dial doesn’t clarify which number represents what temp. That’s why we become confused.

Generally, a higher number indicates a colder setting. For instance, in a 1-5 dial temp setting, number 5 is the coldest, and number 1 is the warmest. When you want things colder, dial up the number. Conversely, when you want things warmer, lower the number. If you’re not sure what temp setting is ideal for your fridge, then set it somewhere in the middle. For example, if the dial is labeled as 1-9, set it at 4. When the dial is labeled as 1-5, set it at 3. You need to wait for 24 hours to see the effect.

However, we want to know the exact temp a particular number represents. But, it’s different in every fridge. So, I suggest you check your fridge’s user manual or consult the customer care service of your refrigerator brand. The best option is to buy a refrigerator thermometer and adjust the temp with it. You should not depend on unspecific built-in refrigerator temp control. 

What is the Maximum Temperature Allowed in a Refrigerator?

The maximum temperature allowed in a refrigerator is 40℉. When the temp goes over 40℉, bacteria start multiplying rapidly. If you are storing eggs, meat, dairy, and produce — don’t let your fridge temp go above 40℉. In addition, keep these food items in the coldest area, such as deep inside your fridge.  

Also remember, the more the fridge door is opened, the harder it is for the refrigerator to maintain the internal temp. Since we need to open the door many times throughout the day, we should keep the temperature a few degrees cooler. The safe refrigerator temp range is 33-38℉. Temperature over 40℉ is the danger zone. 

Besides, your climate has an impact on your refrigerator temp setting. You may need to make slight changes around the recommended temp zone if you live in a hotter environment. Figure out exactly at what temperature you get the best result by using a refrigerator thermometer. Your goal should be keeping foods fresh for maximum hours without freezing it.

At What Temperature Does Food Spoil in the Refrigerator?

Generally, food begins to spoil in the refrigerator when the temp is 41℉ or above. Even if the food items are inside the fridge, an internal fridge temperature of over 41℉ for two hours will spoil the food. So, it’s better to keep the temp under 40℉ to avoid health risks. If you are unsure how long the food items stayed at 41℉ or above, just throw the food out. Sometimes fresh-looking food, which is actually chemically spoiled, can also make you sick. So, don’t take risks.

Some food items are spoiled more quickly than others. Along with temperature, the way you store foods has a great impact on food spoilage. When you are storing eggs, meat, dairy, and produce — don’t let your fridge temp go above 40℉. Try to keep those food items in the coldest part of your fridge. Raw meat, poultry, and seafood should be in a sealed container or wrapped securely to prevent raw juices from contaminating other foods. Read this detailed guide from the United States Department of Agriculture to know more about Refrigeration and Food Safety. 

Throw out anything that looks or smells suspicious. Mold is a sign of spoiled food. It grows even under refrigeration. Discard anything moldy. Your fridge door opening frequency is also a big factor. The more you open the door, the sooner the food items spoil.


Your refrigerator temperature should be below 40℉ or 4℃. Try your best to keep it within 35-38℉. Use a refrigerator thermometer to measure the temperature and adjust temperature controls if necessary. Follow the basic refrigerator storage guidelines and maintain your refrigerator according to the user manual.
