Nowadays, respiratory diseases are an increasingly present reality, whose prevalence continues to increase. Pollen allergies, asthma, bronchitis and much more are diseases that make breathing difficult for many people today, causing symptoms such as a stuffy nose, cough, conjunctivitis and difficulty breathing. All this is mainly due to the increase in external triggering factors, such as dust, pollen, mites, smog, smoke, among others.

It should be noted that thanks to new technologies, if you are also suffering from a respiratory disease that makes it difficult for you to carry out your daily tasks, you can improve the symptoms by purchasing an air purifier. It is a device very similar to air conditioners, but its mission is to return clean air free of pathogens and allergens so that you can breathe better.

That said, it is also important to know that currently on the market you will be able to find a wide variety of purifier models, each with its own characteristics and advantages to improve indoor air quality. Therefore, in today's guide we are going to discover what the perfect air purifier is and how it works, what are the different types of models that exist and what are the factors to consider when purchasing.

What is the best air purifier and how does it work?

As we have mentioned, air purifiers are devices aesthetically similar to air conditioners, which have the mission of eliminating elements present in the air, such as smoke, dust, mites and pollen. That is, thanks to their innovative technology, they can rule out all those polluting factors that can trigger respiratory problems, including allergies and asthma. Likewise, it should be noted that these devices are usually purchased when space is limited and you want to trap odors so that they disappear more quickly. Furthermore, its use is recommended in cities where there is too much pollution.

After having sucked in the air present in the environment and filtered it, it will return cleaner, healthier air with fewer odors, since it is also capable of trapping molecules that cause unpleasant odors.

That said, it should be noted that although there are several technologies that allow air purification, such as electrostatic precipitators or the use of ozone, the vast majority of models available on the market use high-efficiency filters. They are an effective and safe solution that, however, require periodic replacement so that they can complete their mission.

What are the types of air purifiers that exist?

Technology is constantly evolving and that is why currently, available on the market, there is a wide variety of air purifiers to choose from. Now, each of these devices is especially differentiated by the type of integrated filtration system and various technologies to purify the air, as we will see below.

With ozone

Purifiers that produce ozone release this oxidizing gas to eliminate bacteria, viruses, and odors from the air. That is why one of its main advantages has to do with the fact that it effectively eliminates organisms, while neutralizing strong odors present in the environment. On the other hand, it is important to note that sometimes ozone, if present in large quantities, can irritate the respiratory tract. That is why the use of this device is recommended mainly in companies and offices, and not in homes.

With HEPA filter

One of the most effective solutions to purify the air are purifiers with a HEPA filter. For a filter to obtain this designation, it has to respect some standards, among which is to trap all types of particles equal to or greater than 0.3 microns in diameter with 99.97% effectiveness. It is a system capable of capturing all types of micro and larger particles, such as mites, dust, pollen, pet dander and smoke. All this makes it the most recommended and ideal model for people who suffer from allergies and respiratory problems and need to eliminate air pollutants and pathogens present. The only thing that must be taken into account is that the filter must be changed frequently in order to maintain its effectiveness over time.

Activated carbon filter

Another very effective and currently recommended solution is air purifiers with activated carbon. Activated carbon absorbs odors, gases and volatile organic compounds , helping to effectively eliminate odors such as cooking odors, pet odors and tobacco. However, as with ozone purifiers, models that work with active carbon are not as effective at trapping dust or pollen molecules, since they require the incorporation of another filter to be able to perform this type of work.

With ultraviolet ray technology

Finally, you can also select an air purifier with ultraviolet rays. UV light is responsible for inactivating viruses, bacteria and other pathogenic microorganisms found in the air. This makes it a device capable of safely disinfecting the air, without the need for a filter. At the same time, we also have to highlight that although it is a model that disinfects the air, it is not capable of capturing odors.

Criteria to consider before buying an air purifier

Now that you know the different types of air purifiers that are available on the market, the time has come to introduce you to the criteria to consider before making the purchase. Let's not forget that although this device is mainly differentiated by the type of filter it includes, there are also other key factors that must be considered to buy the most suitable model that can satisfy your needs.


As we mentioned above, the main factor to consider is the type of filter that is integrated into the purifier. For those who need to eliminate microparticles such as dust, mites and smoke from the air , it is advisable to prefer the purifier with a HEPA filter, while those who want to disinfect the air to say goodbye to pathogenic microorganisms, it is better to select a model with activated carbon oo UV light sensor.


Just as it is important to select the type of filter needed, it is also crucial to consider the power of the device. Let us remember that power has to do with carrying out the air purification process in the times that the air purifiers offer in their specifications. What you should know about this key factor is that the more cubic meters that have to be covered, the more power the purifier is required to have, power that is given based on the flow rate of the air purified per unit of time . If you buy a portable air purifier, it may be that it does not have enough power, the device will be forced to work for longer, which, in the long run, will affect the performance of the device, its useful life and even consumption. electric. If the room is large, you should find the largest air purifier that promotes air circulation.

Room to purify

Hand in hand with power, it is essential to consider the room to be air purified. We are referring to the cubic meters of room whose air must be purified. This also happens with air conditioners, since having to purify the air in your home or condition a room with 10 square meters is not the same as a room with 50 m³. In order to size the room , what you have to do is calculate its volume, taking the surface area multiplied by the height. Don't forget that purifiers usually have this information in the specifications, or rather, indicate an approximation of the surface that is capable of purifying in a given time. This is essential information when purchasing a suitable air purifier, because it will help us determine what our needs are to avoid buying an oversized device or one that is not capable of covering the entire environment.


On the other hand, it should be noted that another element that is often overlooked but is very important has to do with noise. Although it is true that purifiers, due to their size, are usually portable devices, it must be taken into account that noise is an important factor. Let's not forget that this device is usually used while we are constantly at home, or even while we are sleeping. All this makes it necessary to take a look at the level of noise generated to avoid inconveniences, especially at bedtime. Experts advise noise levels to be less than 30 dB.


In short, choosing the ideal air purifier for your home is not as simple a task as it may seem. Before making your purchase, you'll need to consider a number of key factors, such as the contaminants you want to remove, budget, room size, type of built-in filter, noise, and power of the device. With the purchasing guide for air purifiers that we present to you today, you will be able to discover all the purchasing criteria that you should consider to make the purchase that can satisfy your needs. With this device you can enjoy a cleaner and healthier area in your home or office.
