Humidifier or air purifier: what to choose?

Humidifier or air purifier: what to choose?

Did you know that the air inside our homes is 8 to 10 times more polluted than outside? It is essential to be well equipped with household appliances to improve ambient air quality by noting these figures.

Do not forget to ventilate your home well by opening your windows for at least 10 minutes a day. In this article, we focus on humidifier or air purifier.

These two devices are intended to improve your comfort in your home. However, it is sometimes difficult to know which one to choose when changing the indoor air quality.

We analyze the specificities of each one for you and help you choose between the humidifier and the air purifier.

The humidifier to increase the humidity in the house It tempers the atmosphere and brings humidity to the air

Humidifier or air purifier what to choose

The primary mission of a humidifier is to increase the relative humidity level in a home. Usually, healthy air has a humidity level between 30% and 50%. However, during the winter period, the heating is turned on fully, and the air quickly becomes dry, often falling below the recommended 30% humidity mark.

This lack of moisture can lead to dry skin, itchy and itchy eyes, sensitive mucous membranes leading to nosebleeds or respiratory tract disorders. We, therefore, recommend mainly the use of a humidifier in winter, for sensitive people and prone to asthma problems, for example.

If you have a baby, it’s a good idea to install a baby humidifier in their bedroom to make it easier for them to sleep. In general, babies and toddlers have weaker respiratory systems and are sensitive to surrounding dust.

This device will increase the well-being of everyone in the home and provide healthy and quality air. Some models even offer a small reservoir to add a few drops of essential oils, for a more temperate, relaxing, and pleasant air.

The operating mode of the humidifier

The operating mode of the humidifier

There are 3 types of humidifiers on the market, which remain the same: a base and a water tank.

Then, it is the mode of emission of the vapor which changes

  • hot steam humidifier;
  • evaporative humidifier (cold fog);
  • the ultrasonic (or ultrasonic) humidifier.

Hot steam humidifier

In this model, it is the evaporation of heated liquid that allows the humidification of a room.

The water changes from a liquid state to a gaseous state: it is heated beforehand and comes to a boil in the tank thanks to two electrodes responsible for boiling the water.

All bacteria and microbes present are naturally destroyed by heat up to 80 ° C.

The water ends up turning into vapor, which cools when it passes through a ventilation system.

The device spreads cooled water, which provides a light, healthy and delicate mist that does not require prior filtration.

We appreciate that it can cover large rooms while heating them and mixes very well in the air.

However, even if the water is cooled, the risk of scalding is still present.

It is why we do not recommend installing it in a bedroom or the presence of small children.

Evaporative humidifier

This type of air humidifier offers a vapor rich in humidity, and therefore perfect for readjusting a too low humidity level in the house.

It adapts to each room of the home and can sanitize an area of ​​approximately 30 m².

The bottom of the device has an absorbent filter (or filtration cassette) that soaks up water.

Then, a fan is responsible for diffusing dry air to spread water droplets in the air.

It is a very safe humidifier model if it is well maintained, mainly because it diffuses a cold vapor without risk of burns.

In addition, it is peaceful and affordable in terms of price.

However, do not forget to maintain it regularly and empty its water tank so as not to see impurities and bacteria develop in the stagnant water.

In any case, it is recommended to empty the water tank before each use for all types of humidifiers.

Also, be sure to change the filter regularly, as indicated in the manufacturer’s instructions for use.

Ultrasonic humidifier

These ultrasonic air humidifiers are among the most popular on the market: they are reticent, use less energy than other models and work quickly and efficiently.

This model works by vibration: sound waves, diffused at high frequency, vibrating a metal membrane inside the device.

The water from the tank falls on this metal plate, and this generates a vapor made up of mini-water droplets, which will then be propelled into the air using a fan.

With an ultrasonic humidifier, you can choose hot or cold vapor; that’s the advantage!

However, in this type of humidifier, the water does not undergo prior filtration.

It is, therefore, necessary to carry out treatment against the bacteria and germs present in the water before placing it in the tank.

The air purifier cleans the ambient air and rids it of pollutants.

The air purifier cleans the ambient air and rids it of pollutants

It gets rid of polluting particles and cleans the ambient air.

The purifier has a whole other mission: it cleans the air and rids it of odors and all pollutants, dust, allergens (animal dander and mites) using various filters.

The more filters the purifier has, the cleaner and healthier the air will be for you and your family.

If we mainly recommend a humidifier for people sensitive to dry air in winter, the purifier can be used all year round and for everyone.

Indeed, it provides you with better air quality and frees you from foul odors and pollutants harmful to your health.

We recommend using air purifiers if you have babies or toddlers to reduce the risk of respiratory disorders such as asthma or allergies.

How the air purifier works

The purifier works quite simply: the ambient air in the home is drawn in via a fan, passes through one or more filters, and comes out pure and cleaned.

While the overall design remains familiar to each purifier, the filtration system varies depending on the model.

It is why there are purifiers with a filtration, ionization, or even photocatalysis system.

The filtration purifier

In this model, the air passes through several filters, each with a different degree of efficiency:

  • The pre-filter, which, as its name suggests, is often the first barrier in the path of air.

This filter removes the most multiple residues in the air, such as hair, animal hair, coarse dust, etc.

  • The HEPA filter (for High-Efficiency Particulate Air) is one of the most widespread in the manufacture of air purifiers, in particular thanks to the efficiency of its mesh.

With an efficiency rate of almost 100%, HEPA filters are among the most formidable in existence.

Count on a replacement every 6 to 18 months for optimal efficiency and longer filter life.

Say goodbye to allergens (dander and pollen) and cigarette smoke.

However, it does not retain chemical pollutants or viruses.

  • The activated carbon filter: depending on the type of air purifier, this filter is found in the form of beads or powder.

It has the property of neutralizing foul odors and stopping gaseous pollutants and VOCs (incense essences, scented candles, paints, formaldehyde, etc.)

The more the air purifier has a powerful filtration system composed of different filters, the more you will have clean air and benefit your health.

The ionization purifier

Another way to purify the air in your home is by ionization purifiers.

We know that the particles in suspension are made of positive ions and that the ionizer purifier generates negative ions.

This confrontation of the elements destroys these fine particles, which fall to the ground or settle on your furniture.

You will then have to take care of eliminating them permanently, either by using the vacuum cleaner or with a microfiber cloth to dust your furniture.

Also, note that some innovative models have a filter designed for this purpose, so you will have nothing to do except enjoy a pleasant and secure atmosphere for your family.

The photocatalytic purifier

Purification by photocatalysis is done by emission of ultraviolet light from the device, which will dissolve and destroy the polluting particles via a catalyst, often titanium dioxide.

These particles then become harmless.

But, how does it work?

Using an internal fan, the purifier attracts these harmful particles. It thus gets rid of mold, VOCs, allergens such as dust mites, dander, pollen, chemical pollutant residues, bacteria, and even some viruses!

You probably have the winning combo for healthy air if you pair your photocatalytic purifier with a dehumidifier.

However, to operate, this type of device requires a large volume of circulated air.

It will therefore be noisier than with another type of purifier.

If you are prone to breathing problems from air pollution, an air purifier will make a real difference in your daily life.

In addition, there are some for all budgets, and you can easily find them directly on merchant sites or platforms such as Amazon.

To make your job easier, we’ve compiled the best brands of purifiers in our buying guide, right here!

So what to choose between a humidifier or an air purifier?

The choice will be made mainly according to your needs.

However, the combination of the two devices ensures you a very healthy and safe indoor air for your family.

If you want to act on the humidity of your home’s ambient air without trying to sanitize it, then a simple humidifier will do the trick.

On the other hand, if you are concerned about the risk of respiratory illnesses like asthma, especially if you have children, then an air purifier will be an excellent investment.

But why have to choose when there are 2 or even 3-in-1 devices?

Many devices, such as the Dyson Pure Humidify + Cool, automatically purify the air, humidify it, and continuously analyzes its quality.

Or this Sharp 2-in-1 model that purifies rooms up to 35 m2 and can humidify simultaneously.

It is the best alternative if you don’t want to sacrifice your air quality or humidity level.

Even if they seem more expensive to you, these models save you from buying two devices instead of one and allow simultaneous action, so you never have to choose between humidification or purification.

What you must remember

Both the humidifier and the purifier have the mission to make your interior more pleasant and healthy.

  • The purifier is dedicated to people wishing to improve the quality of the ambient air at home, but who do not necessarily have an interest in bringing back humidity;
  • The humidifier is helpful for households with babies sensitive to the dry winter air when the heating is constantly on. If you also suffer from breathing problems or are prone to dry mucous membranes, this is the device for you.
  • There are devices that combine the two functions and have a beautiful price-performance ratio for their benefits.
