There is a wide variety of air purifiers 2021 and various classifications. Depending on the technology they use, air purifiers can be:

By activated carbon: These purifiers are especially effective in eliminating gaseous pollutants such as smoke and odors. They are widely used commercially, although since they are not very effective on allergens and microorganisms, they are typically used in conjunction with filter technology, especially HEPA.

By ionization: These types of purifiers remove particles from the air using electrical energy, transform the atoms in the air and convert them into oxygen and ozone. Some manufacturers claim that ozone cleans and deodorizes the air, however, there is much controversy about the possible unfavorable effects on health. These types of purifiers have been withdrawn from many countries, as exposure to ozone greater than 0.05 ppm can decrease lung function.

By ultraviolet radiation (UV) : These purifiers use ultraviolet light to soften various particles in the air. This technology is used in many types of air purifiers 2021 to remove harmful pollutants such as bacteria and viruses.

By filtration: These types of purifiers physically trap pollutant particles from the air when it is directed with the help of a fan, through its filter and are usually part of the air conditioning and / or heating system. This technology is the most widely used at a commercial and domestic level .

 Filter types

There are several types of filters:

Normal or non-HEPA:  They only serve to trap large particles, reduce allergens from dust and common dirt, so they are very inefficient. These filters also do not work in removing odors.

HEPA (for its acronym in English High Efficiency Particle Arresting): As its name indicates, they are high efficiency filters (up to 99%) when it comes to removing air particles, because they allow capturing very small pollutants (greater than 0.2 microns) that are in the air.

These filters are the most appropriate and recommended in most cases and the most used by air purifier manufacturers, particularly because of the relationship that exists in terms of quality versus price. Proper maintenance indicates washing or vacuuming them every 3 months in the case of permanent filters or changing them at least once a year in the case of replaceable filters.

MERV:  They are a type of filters denser than HEPA, capable of filtering even smaller particles but, due to their very fine sieve, they also need much more power to filter the air.

 The most popular brands

 Maintaining clean and healthy air is important for everyone, but even more so for those who have problems such as asthma, allergies and other respiratory diseases. If you do not know what an air purifier is for and you have any of these problems, this article will interest you, because we are going to discover a product with which you will always have clean air, free of smoke, odors and dust. Product that we discover knowing some of its main manufacturers and what they have to offer you.

The Bionaire company was founded in 1977, when the first boom in air purifying devices took place. A boom that the company was able to take advantage of by placing itself in the first position of its market thanks to its range of products, which helped it to make the leap to the US market just six years later. Its flagship product, the home or domestic air purifier would be improved a few years later with the ionization system, which reduces impurities in the air and frees it of static electricity and bad odors.

All this innovation reinforced the image of the company, which would later open its market to other products such as fans, air conditioners and humidifiers, thus completing a complete range of products aimed at controlling the air and the environment of our home.

During all this time, the brand has opted for innovation and technical advancement as the key to maintaining its position in the market, so its air purifiers have all the technology we need to keep the air clean and fresh at all times.

Its equipment is also recognized for its low consumption and low maintenance, which is limited to proper cleaning and replacement of filters on the established dates.

This large American corporation is not well known in Spain, except for professionals in the heating sector where it is known for manufacturing all kinds of products and accessories. The entry into the market of its air purification products is giving a new look to the company within the domestic sector of the country.  

In the United States and the rest of the world, the company is a large corporation that distributes all kinds of products. Its catalog included Pentax cameras, home products, aerospace products and many other industrial products and services. In fact, the level of the company is such that it was about to be bought by General Electric in a large operation that was eventually banned by the European competition authorities.

Returning to the purifiers, they are products that have a compact and portable design that allows them to be easily placed anywhere and maintain a tight control over the air quality of the room. If we add an elegant industrial-style design to this, we will also give a special touch to any room.

Nothing is more important to people than their health. This is the motto that Medisana has been carrying as its banner for 30 years, since its foundation, and which implies a commitment to quality that leads to the improvement of the health of its clients.

That is why a good part of its products are considered medical devices, obtained after strict quality controls and a professional manufacturing process.

The company has three main product lines: the aesthetic line, with products for beauty and personal care; the health control line with tensiometers, thermometers or scales; and the home therapy line where we find the air purifiers.

These products are manufactured with an elegant design and a resistant filter manufactured by 3M that guarantees the cleanliness of the environment we breathe. Perhaps a special model is missing, for example for a car, but at least at home we can enjoy the quality of their products.

Frequently asked questions

Q1: What is better between an air purifier and a dehumidifier?

The choice of one product or another depends on the functions the device offers you, your particular needs and your budget. However, we will give you an orientation regarding the operation of each one, so that your decision is the most successful. A purifier cleans the air through filters that capture toxic fumes and harmful particles; Depending on the quality of the filter, it can even trap bacteria and allergens.

A dehumidifier for its part is recommended for homes with a high level of humidity, since it is a device that extracts the water vapor present in the air and returns it to the totally dry environment. In the market there are some models of dehumidifiers that combine the functions of a purifier, in order to provide greater efficiency.

 Q2: What should I do to clean my air purifier?

It is essential to give proper maintenance to the filters present in the purifiers, since the optimal performance of the device depends on it. Depending on its use and the level of dirt present in the air, you should first pay attention to the pre-filters (some carbon and others foam) and keep them clean in order to perform their function properly; This prevents particles from reaching the main filter as much as possible.

To carry out a correct cleaning and without any risk, the first thing is to disconnect the appliance. Then carefully wash the plates with soap and water, rinse well and make sure they are dry for operation. You can also help yourself with a vacuum cleaner with a small nozzle, so that you can remove all the dirt present in all the corners. This process should be done periodically and if there are smokers in the home, it is best to clean the purifier once a week.

 Q3: What is a plant air purifier?

It is a new idea that has recently hit the market. Its creators are French designer Mathieu Lehanneur and Harvard University biomedical engineer David Edwards. Its ecological creation is based on the use of a natural plant that helps the circulation of stale air, thanks to the ability of plants to absorb pollutants and release pure oxygen.

All this with the help of technology, since this project includes a capsule where the plant is located and a fan in the upper part, which works by introducing the air present in the room and then is filtered by the plant through its photosynthesis process. When the air has been purified, the fan blows it back into the room. The most recommended plants for this ecological purification method are the red-edged aloe vera and also spider plants.

 Q4: Which technology provides better environmental treatment, an air purifier or an ozonator?

We cannot compare these two devices, since they are totally different and far from preferring one or the other, their efficiency allows their operation to complement each other in order to provide us with a healthy environment, free of allergens, fumes, mold and other elements. harmful to health.

For this reason, in some cases the purifier will be more efficient, while the ozonator will be more effective in other situations, depending on the particular needs of the family and the power of the equipment.

On the one hand, the ozonator cleans the air while it deodorizes in depth, eliminating annoying odors and organic compounds such as viruses, bacteria, mites, etc. The air purifier on the other hand, offers a comprehensive disinfection of the environment, since it uses different filters and ultraviolet rays, and also includes ozone. It is capable of not only cleaning the air, but it also retains dirt inside.

 Q5: Does an air purifier help improve allergies?

These technology-endowed devices are a great ally in providing a clean and healthy environment for the whole family, especially allergy sufferers. For this, they offer a comprehensive cleaning of the air you breathe, being able to eliminate not only fumes, unpleasant odors and particles from the atmosphere, but also have the ability to capture pet dander, mites and any other type of allergens.

Thanks to an air purifier you can significantly improve your quality of life, with cleaner air that is free of harmful agents. You just have to put it to work in any room, according to your needs.
