air-purifier-what-is-it-for-800

If you care about the quality of the air you breathe in your home or office, you've probably heard about air purifiers. But do you know exactly what an air purifier is for and how it works? We will explain everything you need to know about this device, its health benefits and some of the devices you can buy.

What is an air purifier?

An air purifier is a device that removes impurities, particles and odors from the air, improving the quality of the air we breathe. It is especially useful for people who suffer from allergies, asthma or other respiratory conditions. In addition, it is an effective solution for those who live or work in areas with a lot of pollution.

How does an air purifier work?

Air purifiers work in different ways depending on the model. Some use filters to remove particles and impurities from the air, while others use ionization technology to attract particles and eliminate them. Some air purifiers also use photocatalysis to eliminate odors and bacteria.

What are the health benefits?

An air purifier can bring many health benefits, especially for people who suffer from allergies or breathing problems. Yeah, by removing particles like dust, pollen, fumes and mites, it helps reduce symptoms of allergies and asthma, like sneezing, runny nose and shortness of breath. In addition, an air purifier can also help prevent respiratory illnesses such as bronchitis and pneumonia.

How to choose an air purifier?

When choosing an air purifier, it is important to consider factors such as the size of the room where it will be used, filter efficiency, noise level and energy consumption. For the best results, it's important to choose a template that meets your specific needs.

What is the difference between an air purifier and a humidifier?

While an air purifier removes impurities and particles from the air, a humidifier adds moisture to the air, thus helping to combat dryness in the airways. Both appliances improved indoor air quality, depending on each person's specific needs.

You can use both in your home. In addition, some models of humidifiers allow the use of aromas. They are the aroma diffusers.

Types of Air Purifiers

There are many types available, but the most used are HEPA filters, charcoal and even ozonators. They help remove air pollutants including pollen, dust, dust mites, smoke, odors and even viruses and bacteria. However, there are many types of air purifiers on the market, each with its own characteristics and advantages. See some of the different types of air purifiers available to help you choose the best one for your needs.

1. Air purifiers with HEPA filter

Air purifiers with HEPA filter are the most popular on the market. That's because they use a high-efficiency (HEPA) filter to capture airborne particles. These filters can capture particles as small as 0,3 micrometers, which means they can remove up to 99,97% of pollutants from the air.

These filters are therefore highly recommended, and are also used in some quality appliances such as vacuum cleaners. To learn more you can click on the link above about HEPA filters.

1.1 True HEPA filters

There are two types of HEPA filters: true and false. True HEPA filters are the most efficient and are certified by the US Department of Energy (DOE) to remove at least 99,97% of particles from the air.

1.2 Fake HEPA filters

Fake HEPA filters are filters that do not meet DOE efficiency standards. This means that they may not filter all particles out of the air.

2. Air purifiers with ionizer

Ionizer air purifiers work by generating negative ions that bind to particles in the air. Negatively charged particles attach to nearby surfaces and are removed from the air. However, ionizer air purifiers can produce ozone, which is an air pollutant. It is important to choose an air purifier with an ionizer that produces low levels of ozone.

For example, some evaporative air conditioners come with several advanced technologies - as well as filtering the air, they are also used as an alternative to air conditioning.

3. Air purifiers with activated carbon filter

Air purifiers with an activated carbon filter remove odors and gases from the air. Activated charcoal is a porous material that can absorb gaseous pollutants such as formaldehyde and volatile organic compounds (VOCs).

4. UV air purifiers

UV air purifiers use ultraviolet light to kill viruses and bacteria in the air. UV air purifiers are effective at killing microbes, but they don't remove particles from the air.

Because UV radiation eliminates all microbial beings by doing a deep disinfection. However, care must be taken to connect them in the absence of people, animals and plants. Once turned off, you can safely use the areas where you used it. The germicidal lamp is just one example.

If you want to know more about these devices, be sure to consult our article “What is UV Disinfection and Germicidal Lamp".

5. Air purifiers with plasma technology

Plasma technology air purifiers use an electrical discharge to ionize the air. The ions generated bind to particles in the air, making them easier for the filter to capture.

6. Ozone Air Purifiers

Ozone air purifiers generate ozone to purify the air. However, ozone is an air pollutant that can be harmful to human health, especially in high concentrations. Therefore, when using an ozone purifier, it should be done in the absence of people and animals. At least the most powerful models.

7. Air purifiers with electronic filtering system

Air purifiers with an electronic filtration system use a filtration system that uses an electrical charge to attract particles in the air. The particles are then captured on an electronic filter. This type of air purifier is effective at removing particles from the air.

8. Air purifiers with photocatalysis technology

Air purifiers with photocatalysis technology use a chemical reaction to break down pollutants in the air. The air purifier contains a photocatalytic material that is activated by UV light. When UV light hits the material, it begins to break down pollutants in the air into harmless substances.

9. Air purifiers with ion exchange system

Ion exchange air purifiers use an ion exchange resin to remove pollutants from the air. The air passes through a chamber that contains a resin that exchanges ions with particles in the air. The particles are then captured by the resin.

10. Air purifiers with molecular diffusion technology

Air purifiers with molecular diffusion technology use an adsorption process to remove pollutants from the air. The air purifier contains an adsorbent material that is activated by UV light. When UV light hits the material, it begins to adsorb pollutants in the air.

11. Air purifiers with electronic board technology

These use an electronic board technology. Yeah, that plate is charged and captures particles in the air.

12. Air purifiers with LED light technology

Air purifiers with LED light technology use LED light to kill microbes in the air. LED light is a cold light source that can be used to kill microbes without emitting ozone.

13. Air purifiers with photochemical oxidation technology

These use a photochemical oxidation technology use a chemical reaction to break down pollutants in the air. The air freshener contains a material that reacts with UV light to produce hydroxyl radicals, which are highly reactive and can break down pollutants in the air.

14. Air purifiers with adsorption technology

Air purifiers with adsorption technology use an adsorbent material to remove pollutants from the air.

Which Purifier should I choose?

You can choose a purifier that uses several technologies simultaneously. Well, today there are models that use, for example, HEPA and activated carbon filters. Furthermore, you can complement your HEPA purifier with the ozone generator, as both allow for deeper air cleaning and disinfection.

Conclusion

Investing in an air purifier can bring many health benefits, especially for people who suffer from allergies or respiratory problems. By choosing an efficient model and using it correctly, it is possible to improve the quality of the air we breathe and prevent respiratory diseases.
