An air purifier is a device equipped with advanced filtering technology that traps incoming air pollutants. Air purifiers wipe out impurities like dust, germs, pollens, rust powder, etc., completely from the indoor air, thus rendering it healthy.

What is a humidifier?

A humidifier is an electronic device that helps in increasing the humidity levels inside a room. This is achieved by releasing water vapor particles indoors according to the requirement. A humidifier is usually attached to your room heating or air conditioning systems.

What impact do humidifiers and air purifiers have on your health?

Humidifiers help with chest congestion. 

An extremely dry indoor environment may cause even slight cough and cold symptoms. The mucus accumulated inside your lungs gets dried and sticky due to external dryness. This may cause chest tightness, even leading up to chest congestion. Moreover, dry indoor air may lead to a blocked nose and a sore throat. Things get even worse for people suffering from sinus. Sinus pains intensify to manifolds. Humidifiers help to increase the moisture levels inside a room.

It helps prevent premature aging and dry skin.

If your room air is too dry, it directly impacts your skin. Your skin becomes prone to dryness. It becomes dry and looks dehydrated. The skin may also become itchy and flaky. This May’s excessively dry indoor environment in middle-aged people may cause wrinkles causing premature aging. The problem is, if your area is prone to dryness and is windy most of the time, moisturizer lotions and lip balms will not help. They will provide temporary relief by keeping your skin hydrated for some time. But if truth be told, none of the lotions lasts for long, ultimately leaving your skin exposed to dryness. This is where humidifiers play an important role. They help to regulate indoor moisture levels. Thus dry skin, wrinkles, premature aging, or itchy skin will not be a nightmare for you anymore. You can easily tackle these unwanted problems with air humidifiers.

Air purifiers wipe off toxic chemicals from the air.

Keeping your doors and windows closed does not always ensure that your indoor room environment is healthy and hygienic. Homes are not anyways perfectly sealed, and toxic impurities may find their way inside your rooms through holes and cracks. Outdoor air pollution is everywhere and is a big fatal cause to worry about. All the big reason to worry about exterior air pollution is that it directly impacts your indoor air quality. 

Toxic chemicals like nitrogen dioxide PM and carbon monoxide PM are invisible to the naked eye. So you may think your room air is perfectly pure. But it may be toxic to inhale. In places with more vehicle traffic and industrial pollution, indoor air may get toxic to the point that it triggers fatal health conditions. Air purifiers help a great deal by trapping these chemical contaminants and removing them from indoor air, thus rendering it completely safe.

Air purifiers prevent you from airborne diseases. 

Tiny allergens, harmful bacteria, disease-causing viruses, and other microorganisms can get into your rooms. Unfortunately, these microscopic organisms are not visible to the naked eye. Hence, it becomes more difficult to combat these harmful disease-causing pathogens. Yes, now you may ask—why buy an air purifier when we can regularly clean our homes and keep windows open to ensure sufficient sunlight?

You are right. We absolutely recommend keeping the house clean and sanitized by regularly mopping. We also suggest letting sufficient sunlight inside. All this is fine and good. But you see, even after sanitizing and cleaning, your room is not 100% safe from these germ-causing organisms. They are not completely removed. So you are still putting your health at risk. Air purifiers have advanced technology installed in them by which they filter these microorganisms. They completely wipe them off so that you can be safe from airborne diseases. Also, your family and loved ones are safe.

When to use an air purifier and when to use a humidifier?

It would help if you were using a humidifier for the aforementioned reasons. But there are tons of other reasons you should consider using a humidifier. Before getting to that, you should always remember this fact about humidifiers. Remember this as a thumb rule. Never use a humidifier when the room humidity level is about 50% already. This may lead to adverse effects. So then, how do you know when is the right time to use an air humidifier? 

Well, when humidity levels inside your room fall to 20% or 30% due to external weather conditions or forced room heating, that is the right time. You do not even need to measure for humidity levels. You can notice certain symptoms which tell you that it is high time you switch on the humidifier. For example, if you suddenly feel a shiver or feel your skin shrinking and contracting due to dryness, put on the humidifier. Or, if you feel chest tightness or itchy skin, that may be because your skin is deprived of its natural moisture. It is dehydrated and dried up due to the cold. You can look out for these signs to know exactly when you need a humidifier. This does not always necessarily have to be due to extreme cold weather. It can also be due to generally dry, windy weather or hot summer loo winds.

Additionally, you can verify the need for humidifiers by checking out the condition of your house plants, if you have any. Most house plants are meant to grow and flourish in the wild. This means that they grow best in forests with a lot of moisture concentration. If you have an indoor houseplant and if room humidity levels suddenly drop, you will see some changes in the plants. Not only humans but houseplants too get affected by dryness. You may notice leaf loss, shriveled up leaves, dry leaf tips, stunted plant growth, or shrunken and drooping leaves. Yes, of course, the symptoms will depend on what type of houseplant you have. But you can look out for these above signs in general.

Air purifiers are needed for many different reasons. But most importantly, you need an air purifier even if you feel that there is no need to get one. Confused? Well, you see, pollutants like dust, dirt, pollen grains, or rust powder can still be seen with naked eyes. This is because they get stuck on carpets and rugs, even on walls sometimes. So you know that they are present in your room, and you dust them off. Though you cannot remove them fully, they still can be detected. But the problem with pollutants like microbes, bacteria, viruses, mold spores, and other germs is that they are invisible. They enter into rooms along with the incoming air. They can trigger serious airborne diseases, which can sometimes even be fatal. Now you cannot be running around with microscopes all the time, can you? Moreover, you do not want to risk your family’s health and safety by compromising air quality. Hence air purifiers are an essential purchase. It is not just a luxurious product meant to be utilized only by the rich and elite class. Now you see why.

Differences between Air Purifiers vs Humidifiers

Price of Humidifiers vs Air Purifiers 

There is a big difference in pricing between a humidifier and an air purifier. Humidifiers are quite affordable. In fact, they are priced at reasonably cheap rates compared to the great services they provide. A good humidifier may cost you less than $100. Thus, of course, it depends on the model you are buying. But in general, the price lies within the $100 range or a few dollars more, at the most. But this is not the same for an air purifier.

They are much more expensive. Like, do not be surprised if you have to pay $500 for a single air purifier. Yes, they are costly. Now, obviously, there are cheaper products available which you can easily get for $100. But when buying an air purifier, you must always ensure that it comes with a HEPA filter. These filters are a unique and innovative technology consisting of closely knit threads to help trap any impurities, no matter how small. These HEPA filters are primarily the reason for the high cost of air purifiers. But HEPA filters are a must in air purifiers. Without them, your entire investment is a waste because purifiers Without HEPA filters do a very bad job at air purification.


Is an air purifier or humidifier better for babies?

You want to ensure a safe and hygienic indoor atmosphere for babies and newborns. So it is a valid question to ask as parents. It is even more important because newborn babies are highly sensitive to pollutants. In addition, babies are extremely vulnerable to even the slightest allergens than adults. So it is important to take even more precautions for them.

When deciding on whether to use an air purifier or humidifier for your baby, what you need to consider is the internal and external conditions. So if you live in an area with high automobile traffic congestion, you need an air purifier. Or, if you live in a region with industries prone to toxic chemical emissions, you should opt for an air purifier. This is because even the slightest of gaseous chemicals in your room can prove to be fatal to your baby. Air purifiers take care of that very efficiently.

But if your area has dry and windy weather conditions throughout the year, you must go for humidifiers. This is because dryness may cause disturbed sleep and breathing trouble in babies. Breathing trouble may lead to severe chest pain and congestion. So you should install a humidifier to prevent such unwanted emergencies. But if your area has low air quality filled with contaminants as well as a dry atmosphere, you should buy both air purifiers and humidifiers. You can run both of them at the same time without any risks. It is safe. Make your own call according to your environment.

Does the usage of air purifiers or humidifiers help with Eczema?

Although there is very little scientific evidence to prove that air purifiers and humidifiers help with eczema, people have reported immense relief by their use. Any indoor pollutants can trigger and worsen conditions like eczema or neurosis. Air purifiers literally work wonders in removing even the tiniest pollutants very efficiently. This helps people with eczema or atopic dermatitis. But it is a completely wrong conception that humidifiers help clean the sir. No. Humidifiers are not designed to improve air quality or to trap pollutants. They only regulate the moisture levels inside a room. Long story short, humidifiers do not help relieve eczema, although air purifiers can be a blessing to eczema patients.

Can an air purifier and humidifier be used together?

Yes absolutely! You can safely use and run both an air purifier and humidifier together without any worries.
