Some FAQs on Humidifiers

What should be the optimal humidity level for a bedroom while using a humidifier?

If you are sensing dry skin, an allergic reaction, or is waking up every morning with an irritating throat, then a warm mist humidifier can effectively check and prevent these minor health problems. 

For visible benefits, you can set the optimal humidity level between 45 – 50% for your bedroom. 

However, be sure of your home humidity level before consider buying one. A humidifier releases balanced moisture in the indoor air while a dehumidifier saves you from the allergens that thrive well in excess dampness.

Can I put a humidifier next to my bed?

Well, keeping a humidifier next to your bed is not recommended unless you are facing certain health issues. 

Placing a warm mist humidifier is very beneficial for those suffering from bleeding nose due to extreme seasonal dryness, sinus issue, nose congestion, and scaly skin.

With a humidifier near your bed, you are prone to certain risks, but the moisture emitted from this device can get you rid of those miserable mornings with congestion-free air passages and well-hydrated radiant skin. 

Can I run the humidifier and air purifier in the same bedroom?

Yes, you can have the benefits of both humidifier and air purifier in your bedroom by placing them a bit apart from each other. 

While a purifier efficiently improves the indoor air quality by filtering out allergens and heavy particles, the humidifier curbs down excess dryness in the room air by adding a balanced moisture level.

In fact, you can find 2 in 1 combo of air purifier and humidifier which is worth a deal as a single solution to several problems.

Should I close the door when using a humidifier?

Well, that depends on specific needs. 

Sometimes, excess room humidity can lead to ugly mold patches on the walls with an adverse impact on your health by triggering the growth of various allergens and particles.

For a balanced moisture level inside, sometimes it’s okay to keep the windows and doors open to let free airflow inside.

Also, a quality humidifier with built-in sensors automatically detects and adjusts the humidity level so that you don’t need to open the windows during harsh winters.

Should humidifier run all night?

If you are an inhabitant of a dry region and often experiences sleepless nights due to congested nose, and blocked air passage or is having bad mornings accompanied by the soaring throat and dry eyes, putting on a cool-mist humidifier all night long can effectively help in alleviating such problems by providing enough moisture.

Get uninterrupted sound sleep with an auto-adjusting humidifier near your bed that efficiently does its job in balancing the optimal humidity level of your room like a pro. 

What water to use in a humidifier?

A humidifier humidifies your room’s air which means the water inside the unit must be clean enough to release pure quality breathable air. 

To get the purest form of air to inhale, distilled water is recommended by the experts to be used in a humidifier.

Heavy particles like magnesium and calcium in unfiltered tap water, when put inside the humidifier have a fair chance to clog the filter and damage its function while making the indoor air quality poor and heavy to inhale. 

Can a humidifier cause dampness and mold?

Too much of everything is injurious and so is a humidifier. 

Moisture-laden air can have a lot of adversities on your home and health.

Get ready to experience mold patches on the walls and dampness everywhere, triggering the rise of allergens along with various health issues like asthma attacks, runny nose, whooping cough, watery eyes, and chronic respiratory diseases when a humidifier releases excess moisture indoor. 

Use a warm mist humidifier as the warm steam rules out the chances of mold build-ups.

Can I put salt in my humidifier?

Adding salt depends on the kind of humidifier you are using. 

Mixing salt in a cool-mist humidifier is of no use as they don’t work by heating. 

Go through the instructions manual to avoid any mishaps. 

Salt is just like other minerals in unfiltered water which boosts the boiling point inside to produce more steam, which works great with a steam humidifier, but the corrosive salt will eventually hamper the lifespan of the unit. 

Make sure to clean your humidifier thoroughly after every use.

What is the difference between a cold mist humidifier, warm mist humidifier, and steam humidifier?

A cool-mist humidifier is a safe option to avoid risks as they disperse cool mists in the indoor air with ultrasonic vibrations that atomizes the water into breathable microparticles. 

Whereas, a warm mist humidifier releases warm mist that generates from the boiling water heated inside, using electricity. 

A steam humidifier and a warm mist humidifier works almost in the same way, except, the steam one filters out the impurities that get deposited on its bed before releasing the hygienic mist out. 

While with the warm mist units, there is a probability of the impurities getting released in the air where it settles as heavy particles making the indoor air quality poor to inhale.

With a steam humidifier, you may need to add salt to increase the boiling point, but a warm mist humidifier doesn’t need any extra add on minerals, it works decently with clean distilled water. 

Cool mist humidifier is a safer choice especially for toddlers and pets, while warm mist humidifiers involve the risk of the hot water getting spilled, causing serious burns.

Warm mist humidifiers effectively combat excess dryness but can be avoided during the summer, while a cool mist is an ideal choice if you want to run humidifier 365 days.

What is the difference between humidifiers and vaporizers? Which is best for asthma: a vaporizer or a humidifier?

Both are made to lend a balanced moisture level in the indoor air, aiding in relief from dryness and its harsh impact on health. 

However, certain minute discrepancies make them a bit different.

Vaporizers work in the same way as that of a warm mist humidifier that releases sterilized mist from the boiling water heated by electricity. 

This warm mist is extremely beneficial for people suffering from asthma and sinus issues that mostly triggers during the winters. 

Whereas, the other humidifiers function differently in dispersing the moisture which doesn’t necessarily go through any heating and multiplies the risks of impurities getting released in the indoor air further deteriorating any such existing health conditions.

Bacteria and mold build-ups are less in vaporizer due to high heating while other humidifiers are prone to such bacterial and fungal damage.
