Improving Air Quality and Moisture

When the moisture content in the air is less than 30%, it indicates that the atmosphere is dry, which can cause numerous skin issues, including a sore throat, eye irritation, and dry skin.

The most effective tool for improving air quality and moisture in the air is a humidifier, but can you use humidifier and air purifier in same room?

Yes, a humidifier and an air purifier may be used in the same space to perform separate tasks while complementing each other. However, placing them too close together might cause issues since the moisture from the humidifier can clog the air purifier’s filter and reduce its efficacy.

Because air purifiers and humidifiers are so different, it’s crucial to examine their characteristics and how they might work together.

So after discussing the question, ‘can you use humidifier and air purifier in same room?’ Let us move towards the difference between air purifier and humidifier.

Air Purifier and Humidifier Difference

Humidifiers and air purifiers are two types of equipment that will help you improve the quality of your air. Humidifiers create a more humid environment, whereas air purifiers remove contaminants from the air.

When one or both of these systems are insufficient, numerous problems can arise in comfortable living, but knowing when to employ them is crucial.

Air purifiers come in a variety of sizes. Compact designs that are lightweight and simple to transport are available, as well as larger appliances that weigh several pounds. Lightweight air purifiers can be placed on a nightstand or at an office desk, whereas floor-based warm and cool mist humidifiers are tiny.

Cool and warm mist humidifiers have a small design. As a result, air purifiers are considerably larger since they accommodate many filters.


A multi-stage filtration system is featured in an air purifier. An activated carbon filter, HEPA filter, and pre-filter are all included. Some also have an ionizer and a UV-C light. Many of them feature an air quality sensor that measures particulates and VOCs in the air.

Comparatively, humidifiers have a water tank that adds moisture to the air. This helps relieve any irritation caused by dry conditions. Humidifiers also include a hygrometer to measure air humidity (RH).

Health Benefits

Air purifiers capture and remove pollutants and disinfectants from the air. As a result, they are helpful to allergy sufferers and those with bronchial problems.

The humidifier is beneficial for asthmatic patients who suffer from dry airways or have irritated respiratory tracts. The humidifier adds moisture to the air for better living conditions.

Noise Level

The speed of the fan determines the noise level of an air purifier. The ambient noise level can range from 20 to 40 decibels at the lowest setting, and it can reach up to 65 decibels at the highest setting.

Ultrasonic humidifiers are most prevalent. As a result, they run very quietly. This implies they may be used in your bedroom without interrupting your sleep patterns.

Humidifiers can assist with a variety of issues caused by dry air, including:

  • Frequent nose bleeding
  • Common cold
  • Sore throat and irritating eyes
  • Asthma attacks
  • Dry hair and skin
  • Snoring
  • Sinus congestion

Your skin will be dry if the air is too dry. Your respiratory tract demands lubricants as the humidifier is used to boost water vapor concentrations in the air so that your body may get adequate moisture.

The mucous membranes of the body begin to dry out, and breathing becomes difficult if there is not enough moisture.

The relative humidity, or RH, of space is the amount of water vapor present in it. The US EPA (Environmental Protection Agency) recommends that an indoor environment have a minimum of 35% relative humidity to keep people hydrated enough to perform their daily activities.

Types of Air Purifier

Air purifiers are a valuable method of removing pollutants and improving interior air quality to minimize health hazards. Air purifiers are classified into several groups depending on the way they clean the air.

UV Technology Air Purifiers

UV technology is somewhat more effective at removing small organic pollutants, such as viruses, germs, and bacteria, present in the air. UV technology is less prevalent than activated carbon filters on air purifiers or HEPA.

That’s because the debate is still out on these. Many studies exist showing how UV light destroys germs, but many devices advertising this feature have fallen short of people’s expectations in terms of usefulness. So, if you are thinking about purchasing an air purifier with UV light, do your homework first.

UV air purifiers are not the same as ozone air purifiers, which can be harmful. While UV light is not poisonous in and of itself, it does not pose any risks as ozone does. Look for a UV air purifier that does not generate any ozone. The result is to conduct extensive research before buying one of these items.

Activated Carbon Filters on Air Purifiers

Air filters are made from carbon materials such as charcoal or bamboo. They feature a large porous surface area, allowing air pollutants to be readily absorbed.

The filter pores trap smaller pollutants that a HEPA filter can’t capture because of their tiny molecular size. Such cleaners, which are sensitive to particles with small molecular sizes, like chemicals and odors, are ideal for both commercial and residential use.

When it comes to odor removal, activated carbon filters are best when they are heavy and made up of granules (rather than being a sprayed-on layer inside an air purifier), but you will pay more, of course.

We recommend experimenting with a few activated carbon bags and planting them around the home where you notice the most chemical smells and odors if you are just getting started.

HEPA Air Purifiers

The most effective type of air purifier is a HEPA (high-efficiency particulate air) filter. These filters include a foldable accordion-like surface that allows them to trap as many pollutants as feasible.

However, when purchasing a HEPA air purifier, be wary of manufacturers that claim their filters are “HEPA-like” or “similar to HEPA.”

Humidifiers are the most effective technique for treating dry air, generally found in many houses throughout the winter months. However, it is essential to understand the many sorts of humidifiers available on the market and how they humidify the air before purchasing one.

Whole-House Humidifier

Whole-house humidifiers are generally connected to your home’s HVAC system, although they do not have to be. Furthermore, such humidifiers are hefty and big; thus, transporting them from one location to another may be difficult.

These humidifiers include huge tanks that can store water for days but are tough to keep clean. Whole-house humidifiers also come with air filters that must be cleaned after three months.

Ultrasonic Humidifier

Ultrasonic humidifiers work by causing water to vibrate using the power of sound. A metal diaphragm in an ultrasonic humidifier vamp releases cool fog water droplets.

Ultrasonic humidifiers are simple to maintain, but you may notice white dust on furniture after usage. It is a typical problem with cold-air humidifiers; however, it can be avoided using distilled water instead of tap water.

Cold Mist Humidifier

The filter is put in the cold mist humidifier, which keeps pollutants from combining in the air and producing fog. Cold mist humidifiers are simpler to maintain than warm mist humidifiers since they do not need cleaning as often, but cover more significant ground because of their identical capacity.

The noise produced by a cold mist humidifier (versus the warm mist one, which is quiet) makes it unsuitable for nighttime use in the bedroom. Furthermore, owing to the filter, this humidifier requires more regular maintenance.

Warm Mist Humidifier

The heating mechanism inside warm mist humidifiers is usually placed within the device. Water is changed into warm mist vapors using this heating mechanism. Because the steam produced by this method is clean, it is becoming more popular as a way to cure seasonal colds.

Despite their benefits, warm mist machines are large and hard to maintain. Furthermore, it is essential to remember that it generates hot steam and should be avoided by pets and children.

Air Purifier and Humidifier Combo
