Air Purifier VS Dehumidifier: Which Is Better?

Air Purifier VS Dehumidifier

Air Purifier VS Dehumidifier

Air purifier comes in different sizes and shape of form including a slim tower framework. Barring the renewable type, dehumidifier is typically in boxy shape to accommodate a reservoir. An air purifier works by circulating air through its internal filtration. Airborne irritants like dust, mold, pollen, smoke to the extent of germs will be trapped by the filter. On the other hand, dehumidifier works by sucking out moisture from the air. This would halt mold and other microbes growth as thrive on high humidity environment. Air purifier and dehumidifier can relieve discomfort from allergic reactions. This includes cough, sinus, itchiness, headache or breathing problems. The difference with a dehumidifier is more restricted to mold and microbes allergies. Air purifier can target a boarder range of indoor allergies.

Air purifier can be placed anywhere indoor but bedroom and living hall is the popular spot. Dehumidifier is often placed in the basement due to poor ventilation and no sunlight. Both appliances are suitable for all age group from newborn, baby, children, to adult. Noise level favors air purifier more as dehumidifier’s motor fan noise can be intrusive on higher speed. Price point is also similar at lower-end category but the gap widens for higher-end models. Air purifier calling the higher shot because of the complexity filtration and features.

Do I Need an Air Purifier or a Dehumidifier?

Get an air purifier if you are allergic to dust, mold, pollen, pet dander, germs, and the list goes on. Works well for smoke particles coming from cigarette, cooking, or chemicals if you have carbon filter installed. Get a dehumidifier if the air feels damp with a hint of musty smell (mold is here). If you have hygrometer/ humidity meter at home, you can keep track when humidity level goes beyond 50%. Summer is also a good time to get one.

Air Purifier VS Humidifier: Can I Use Both At The Same Time?

Air Purifier VS Humidifier

Air Purifier VS Humidifier

The classic same difference. An air purifier removes airborne contaminants from the air. This includes dust, mold, pollen, spores, pet dander, bacteria, smoke, and odors. A humidifier pump moisture back into the air to curb the spread of viruses. Air purifier typically has a bigger body to fit its multi-layer filtration. Humidifier is much smaller in size that is mostly covered by a water reservoir. Air purifier stops airborne contaminants from spreading and aggravating respiratory diseases. This includes sinusitis, pulmonary edema, respiratory tract damage, asthma and more. Humidifier moisture skin, nasal airways and relieve discomfort from dry cough, and dehydration. Humidifier also reduces static electricity. Air purifier does not change a room humidity level but humidifier does. Anyone can benefit from an air purifier or humidifier but children, asthmatic, and an allergenic person would reap the most.

Moving to location, air purifier can be placed anywhere in the house. We recommend placing it in the bedroom or living hall where you will spend the most time in. Humidifier is frequently placed in a bathroom or bedroom when one is applying skincare. Noise wise, an air purifier is distinctly louder with its spinning motor fan. Finally and perhaps most importantly for some, the cost of ownership. Air purifier is generally pricier without even accounting for the filter replacement cost. Humidifier is a one-off cost excluding any optional essential oil add-on.

Do I Need an Air Purifier or a Humidifier?

Get a humidifier if your house humidity level falls below 30% (Ideal level is between 30-50%). When the air feels stale and stuffy (winter is coming), humidifier would ease the breathing space. Look for symptoms like itchy/ flaky skin, chapped lips, or dry cough. Static shock is also a sign of dry air. Get an air purifier if you are allergic to dust, mold, pet dander or anything that floats. Air stinks from fire burning, cigarette, or chemical emission, get one. Just had a baby, asthmatic person or anyone with weaker immune system, you know the answer, get one!

Humidifier VS Dehumidifier: Which One Do I Need?

Humidifier VS Dehumidifier

Humidifier VS Dehumidifier

Let’s go through key differences. Humidifier adds moisture into the air through the release of cool or warm mist. Dehumidifier would bring the humidity level down by absorbing moisture from the air. At the end of the day, Humidifier reservoir will be empty through water dispersion. Dehumidifier water reservoir will be full through water collection. Humidifier is best used to keep skin hydrated, clear nasal passage airways, alleviate dry cough, and throat irritation. Dehumidifier is best used to halt microorganisms like mold from growth. This would curb down symptoms like sinus, red eyes, cough, itchiness, and headache. Popular spot for humidifier is bathroom or bedroom; dehumidifier is often placed in the basement due to poor ventilation. Noise level favors more to the former than the later traditional refrigeration or desiccant mechanism.

You can find humidifier in evaporative form, steam vaporizer (cold & warm mist), ultrasonic, or impeller. Whereas for dehumidifier mechanical, refrigeration, absorption/ electronic desiccant, thermoelectric, or ionic membrane. Lastly, humidifier is generally cheaper but costlier to maintain if you account for the essential oil add-ons (optional). Dehumidifier on the other hand, is more expensive but with zero maintenance cost if no replaceable filter is involved.

The Differences Between Humidifier and Dehumidifier

Subtle to soft for ultrasonic, cool mist. Livable white noise for impeller, warm mist (steam).Louder but manageable noise level depending on the selected speed and placement.
Cost with Upkeeping
Cheap for a compact vaporizer/ cool mist between $20-50. Expect price from $100 all the way to $500 for 2-in-1 air purifier humidifier combo.Mini/ portable unit is at an affordable price of $30-50. Expect price between $100-300 for a full-sized 30-70 pint dehumidifier.

Do I Need a Humidifier Or a Dehumidifier?

Get a humidifier if your room humidity level falls below 30% or the air is stale and dry e.g. in the winter. If you often fall sick from virus infection, humidifier can stop the spread. Get a dehumidifier if humidity level goes beyond 50% or the air is humid e.g. in the summer. Consider one if your house is constantly infested with mold. Ideally, the sweet spot is between 30-50% humidity level. Achievable but you will have to swap the machine during season change.

Too technical? No problem. You can also rely on your allergies to determine what is needed. If one is experiencing the following symptoms:

  • Itchy or flaky skin
  • Chapped lips
  • Dry or nose bleeds
  • Dry cough
  • Breathing difficulty
  • Static shock

Humidifier it is. Start using a dehumidifier if you experience the following signs:

  • Stuffy or runny nose
  • Postnasal drip coughing
  • Bloodshot or watery eyes
  • Dry throat
  • Itchiness all over the body
  • Headache or dizziness
  • Wheezing or shortness of breath
  • Static shock (again)

My take? Skip the second option as most symptoms are repetitive and can be caused by any allergies. Instead, get a hygrometer/ humidity meter for less than 10 bucks and you will have a clear answer.

Air Purifier VS Humidifier VS Dehumidifier: What’s The Differences

Air Purifier VS Humidifier VS Dehumidifier

What is an Air Purifier and How It Works?

AKA air cleaner is a device that pulls in and traps airborne irritants in the air. This includes dust, dust mite, pet dander, mold, pollen, mildew, bacteria, and viruses. With an activated carbon filter, it can remove smoke from cigarette, miscellaneous odors, chemical fumes and so much more. With all harmful particles trapped, the air purifier can circulate back clean air to the room. There are many different types of air purifier in the market, we always recommend people to go with a conventional HEPA air purifier. It is the safest, efficient and proven on its reliability.

What is a Humidifier and Dehumidifier?

Humidifier is a device that increases the humidity level in a room. Dehumidifier works the opposite that decreases humidity in a room. There are 4 common types of humidifiers in the market: Evaporative, Steam vaporizer/ Mist, Ultrasonic, and Impeller. As for dehumidifier, there are Refrigeration, Absorption/ Electronic desiccant, Thermoelectric, and Ionic membrane.

So Air Purifier, Humidifier or Dehumidifier?

Short and sweet: Air purifier plus humidifier or dehumidifier. The sweet spot for humidity in a room is between 30 to 50 percent. You need to figure out what is needed and what works best to maintain a longevity clean air.

Need a little bit more convincing? Better air quality means better health and quality of life. If you experience ANY allergic symptoms consistently, get an air cleaner. Humidifier if you have a dry throat, flaky skin, or sinus just after waking up. Home constantly infested with mold, dehumidifier it is. Summer air = high humidity, winter air = low humidity. Pro tip: There are seasonal allergies or even haze invasion. During that period, most purifiers would be sold off thus there is limited room for price bargaining. So please be well-prepared before it happens.

How About Air Purifier with Built-in Humidifier? Yay or Nay?

I have nothing against an air purifier humidifier combination if it can deliver the “goods” (airflow output). You will use less electricity and have one less device to maintain. It’s not the best choice if you have a budget constraint. Also, most top models in the states is a standalone unit rather than a combo. If you don’t mind eating up your interior space, there is no difference in having two units running at the same time. Both air purifier and humidifier will complement each other existence well.
