What are the differences between purification, depuration & sanitization?

3 words that are often mentioned in this complicated period. But do they mean the same thing or are there some differences?

In this difficult period, we often hear about how important it is to have a healthy, clean, and pollution-free environment.

Due to the increasing time we are forced to spend inside our homes, it is our duty to take care of our interior spaces to ensure that the air we breathe is fresh and clean: breathing well helps concentration, mood and makes us feel better!

But what are the gestures to be made in these cases? What should we do to ensure high-quality indoor air every day? Surely you have heard phrases like this:

  • "It is necessary to purify the air we breathe to avoid inhaling pathogens"
  • "We need a depuration before..."
  • "All people have to sanitize the building ..."

All these terms apparently seem to mean the same thing, but they actually have different meanings.

So what are the differences between purification, depuration, and sanitization?


When we talk about air purification we mean all those processes that are needed to remove impure substances, therefore pollutants and contaminants, present within an internal space, which make the air renewed and free of any impurities.

This process can be carried out through the use of air purifiers which, thanks to their filter, are able to retain these pathogens and unwanted agents, continuously releasing clean and healthy air that allows you to breathe better.

Unfortunately, the main air purifiers on the market require a continuous change of the filter to be permanently effective, and this can become very expensive and not very eco-sustainable in the long run.

For this reason, we recommend the use of Natede and Eteria, our air purifiers made with biomaterials that don’t require any filter replacement.

In fact, Natede and Eteria are equipped with a special filter that uses powerful nanomaterials capable of purifying your air thanks to a cutting-edge technology called "photocatalysis". This special feature allows the filter to never be changed but to be simply rinsed under the water only a few times a year.

Natede and Eteria eliminate:

  • -93% of VOCs
  • -40% of fine particulate (PM 2.5)
  • -99% of viruses and bacteria


It's a similar process as the purification but it regards fluids. The final purpose is always to remove contaminants and all substances that do not make the fluid suitable for its use or that can make a liquid dangerous or unusable.

So the big difference is that a purification process is required to make the air pure (in our case, we use photocatalysis because it is one of the most effective and low-energy technologies) while for what concerns the fluids, depuration tools are needed to make them free of pathogens and pollutants.


In this period, the word sanitization is used in all those cases where it is necessary to make an environment free of viruses and bacteria, in order to not run the risk of being contaminated by these pathogens that can harm our health.

In fact, normal cleaning is not sufficient to remove all these harmful microorganisms, and it is therefore necessary to use a practice such as sanitation to ensure that there is no trace of viruses and bacteria on every single surface and space of the environment.

To proceed with this type of practice, it is necessary to use chemical detergents or industrial substances that are able to significantly reduce (almost equal to 0) the amount of polluting microorganisms. Specific procedures are also required to make an optimal sanitation: one of the best methods to perform proper sanitation is to follow the instructions of specialized bodies such as the WHO (World Health Organization) which has issued an official document listing the procedures and optimal actions to sanitize your indoor environments: Water, sanitation, hygiene, and waste management for SARS-CoV-2, the virus that causes COVID-19

So it isn’t a natural process, but it requires chemicals to be put into practice through human intervention and can take a lot of time (and money) to be done properly.

The term "chemical cleaner" must in no way be misunderstood with toxic substances or associated with something that hurts: it’s the opposite! Especially in this period, it is absolutely necessary to use sanitation to protect ourselves and other people from viruses and bacteria that could compromise our health.

Take care of your indoor air

Thanks to our Natede and Eteria air purifiers, you can get purified and healthy air at any time of the day, breathing better and living better.

Natede and Eteria are 100% made in Italy with biomaterials, and they allow you to monitor your air in the app Vitesy Hub, thanks to their IoT technology.

In this period, our purifiers can make the difference and be essential, because they can eliminate viruses and bacteria in a non-chemical and natural way, so as not to overload the environment with chemicals already present in the sanitation processes.
