How do air disinfectors reduce bacteria in air?

What are the main causes of air pollution?

The first source of contamination is that which comes from outside, entering rooms through windows, doors or through poor ventilation.

However, eliminating natural or artificial ventilation also has its consequences.

Unventilated classrooms can host CO2 concentrations ranging from 1500 ppm to 3000 ppm.

On the other hand, we must pay special attention to the temperature and humidity present in the interior school space, because they are among the factors that affect air quality.

Air disinfectors kill Dangerous air pollutants

Some dangerous air pollutants are:

• Dust
• cleaning supplies and
• disinfectants, gas leaks, or residues from construction sites near the educational establishment.

We can also find fungi, bacteria, viruses, spores in bird feces and mites. We can clean them using air disinfectors.

Among the viruses is COVID-19. At the beginning of the pandemic, the main cause of spread was thought to be coughing or sneezing.

Furthermore, in educational institutes, young people may be more sensitive to pollution than adults.

For what reason we need air disinfectors? 

They generally breathe more air and drink more fluids relative to their body weight.

For this reason, exposure to indoor air pollution practically doubles the risk of respiratory diseases, such as pneumonia, during childhood.

What are air disinfectors?

A practical solution to avoid the threats present in closed spaces in schools is to improve ventilation, and for this, installing air disinfectors is an effective solution.

What are they about? They are equipment designed to eliminate harmful gases, particles and pollutants suspended in the air from closed spaces.

This is achieved thanks to the fact that it is equipped with a HEPA filter, a carbon filter and a multilayer filter.

Thanks to these filters an air purifier can eliminate more than 99% of particles in the environment, which includes:

• Bacteria
• Mold spores.
• Allergens
• Smoke particles.

Why is it important to integrate it into educational establishments?

Using an air cooler purifier in an enclosed space greatly reduces the concentration of ultrafine particles in the air.

Air Purifier: Is It Really Effective?

The importance of air quality

One of the essential factors for well-being indoors is air quality. According to the Directorate-General for Health, daily exposure to air pollutants results in large part from inhaling indoor air, not only because of the time spent inside buildings, but also because the levels of indoor air pollution are generally very high.

This means that while the population is concerned only with outdoor air pollution, which is easily perceived in large urban centers, it ends up forgetting (or not knowing) that indoor air pollution can also have harmful effects on health.  You need air disinfectors.

US Environmental Protection Agency studies of human exposure to air pollutants indicate that indoor levels of pollutants can be up to 5 times higher than outdoor ones – occasionally even more than 100 times.

The origin of indoor pollutants

Some of the internal pollutants originate from the external environment, while others originate internally, based on everyday situations, such as cleaning the house and cooking, or even from building materials, tobacco smoke, or even furniture.

These pollutants can be present in the environment in the form of gases, vapors and particles. As an example we can cite common contaminants that exist in our homes, such as formaldehyde, molds and pollens.

How do air disinfectors reduce bacteria in air?

To eliminate these polluting s best to reduce or remove the sources are air disinfectors. There is also a very effective option which is filtration, a useful mechanism to supplement both the control of the source of pollutants and ventilation.

If you already have an HVAC – Heating, Ventilation and Air Conditioning system, it is important to periodically change the filters or use a portable air purifier, which will reduce exposure to pollutants, in order to improve indoor air quality.

There are two basic categories of air purifiers:

• 1 – Portable air purifiers
• 2 – HVAC/ heating filters or duct mounted air purifiers.

Portable models are generally good to clean the air in spaces such as a medium-sized living room, bedroom, or office. These air disinfectors can be small or larger units and can usually be moved.

Heat filters and other duct-mounted air filters are installed in a home’s central HVAC system and can supply filtered or clean air to many parts of the home at the same time, as long as the system fan is running.

What are the advantages of an air purifier?

There are several benefits of purchasing an air purifier. The different technologies that can exist in these devices have a common goal: to reduce or eliminate exposure to airborne contaminants such as:

• fungus spores
• Bacteria
• Pollensand other pollutants

Some air fresheners can also be allies in removing odors from the environment.

Several studies of portable air disinfectors with HEPA filters have shown small improvements in cardiovascular and respiratory health. HEPA filters are those that have technology with high efficiency in retaining particles.

And even though it is not always possible to immediately perceive the positive changes that are taking place, health professionals are able to identify them.

In the case of people with respiratory allergies or asthma, this improvement may be even clearer, since the presence of one of these devices in the bedroom, for example, can reduce some of the recurrent symptoms of these conditions.

Types of Portable air disinfectors

Basically, air disinfectors have specific technology for cleaning indoor air and, in some cases, fans to drive air through the purifier.

There may also be other technologies that focus on different functions, such as activated carbon to reduce odors, or others that assist in the removal/inactivation of pollutants. Some of these technologies are aimed at:

• Gases(catalytic oxidation, plasma and intentional ozone generation, etc.);
• Particles(electrostatic precipitation, ionizers, filters, such as HEPA, etc.);
• Or even microorganisms(ultraviolet irradiation, etc).
