Frequently Asked Questions

The number of Air Changes per hour is key to the creation of “Safe Clean Air”.

Despite being a requirement under law to provide safe, clean air, Before the outbreak of Covid 19, the importance / necessity of Air Filtration for employees, patients, students, residents, visitors and customers was not considered widely, outside of acute environments such as operating theatres, data centres and pharmaceutical environments.

Covid 19 has shone a light on this area and brought attention to airborne transmission of viruses, influenza and other dangers which live and transmit in non-clean air.

Governing bodies / national bodies now recommend multiple clean air changes/ filtrations per hour (As opposed to air circulation, which does not filter the air).

Your Mia Air expert will be able to talk you through how many air filtrations are required per hour in your setting.

HEPA  (High Efficiency Particulate Filtration) Filtration systems are recognized and recommended  to filter the air indoors.

HEPA 14 Air Filtration was designed for use in high-risk areas such as operating theatres, pharmaceutical production, data centres and nuclear sites.

Hepa 14 Filters which are standard on Mia Air, are at least 99.995% effective in capturing viruses and Bacteria.

ULPA 15 Filters as used in the Mia Air Tower are at least 99.9995% effective in capturing viruses and Bacteria.

SARS-CoV-2 viral particles, like other viruses spread between people more readily indoors than outdoors.

When indoors, ventilation mitigation strategies help reduce viral particle concentration. The lower the concentration, the less likely viral particles can be inhaled into the lungs, contact eyes, nose, and mouth, or fall out of the air to accumulate on surfaces. Protective ventilation practices and interventions can reduce the airborne concentrations and reduce the overall viral dose to occupants.

HEPA filters are no less than 99.97% efficient at capturing human-generated viral particles associated with SARS-CoV-2.

HEPA filtration units that combine a HEPA filter with a powered fan system are a preferred option for auxiliary air cleaning, especially in higher-risk settings such as health clinics, vaccination and medical testing locations, workout rooms, or public waiting areas

HEPA Filtration systems are recommended by authorities such as the Centre for Disease Control, WHO and SAGE in the United Kingdom / HSE in Ireland as part of the solution for Improving Indoor Air Quality

Most people are aware that outdoor air pollution can impact their health, but indoor air pollution can also have significant and harmful health effects.
EPA studies of human exposure to air pollutants indicate that indoor levels of pollutants may be two to five times — and occasionally more than 100 times — higher than outdoor levels.1

These levels of indoor air pollutants are of particular concern, because most people spend about 90 percent of their time indoors.

In fact, many office buildings have significant air pollution sources. Some of these buildings may be inadequately ventilated. For example, mechanical ventilation systems may not be designed or operated to provide adequate amounts of outdoor air. Finally, people generally have less control over the indoor environment in their offices than they do in their homes. As a result, there has been an increase in the incidence of reported health problems.

Approximately 20% of employees suffer from some type of airborne allergen. with hay fever being the most common Airborne Allergen with 7% of people affected.

Mia Air has been extensively tested and is certified by the independent body ECARF.

The ECARF seal of quality is a label for allergy-friendly air purifiers that are able to achieve a measurable improvement in air quality for the indicated room volume with normal use,
