There are new concerns about the importance of the air we breathe and the effects on health. Our team has reported various benefits from the smart green walls and purifiers being used in our offices, including feeling more alert in the afternoons, better skin and drinking less caffeine.
Air pollution is an invisible killer. It kills more people than wars, natural catastrophes and traffic incidents combined. The latest data and guidelines confirm a long-standing belief. among doctors and experts about the spread of viruses by air. Research shows that virtually all droplets smaller than 50 micromillimeters – many of which are from coughing – dry out before hitting the floor. However, they attach to larger particles that remain floating with the indoor air currents.
Experts believe it is possible that the viral content of these particles may be sufficient to cause coronary infection. Guidance on keeping distance is a good starting point when considering safety solutions for open plan offices, restaurants and other public indoor spaces. However, distance recommendation are difficult to maintain and monitor at all times. The movement of people, the opening of doors and airflow caused by ventilation effectively spread aerosols that carry a risk of adhesion very well. The air suspension time of these aerosol clouds can be reduced to a fraction with air purifiers based on the latest research and technology.
You breathe 10,000 liters of air a day. The most important thing you put in your mouth is the air you breathe. Indoor air quality is affected by several different sources, causing a range of symptoms, illnesses and chronic ailments.
It’s topical to talk about Coronavirus, but most flu threads originate from indoor air problems. In public spaces where large numbers of people move, and at the same time the number of bacteria and viruses in indoor air increases.
In the manufacturing and finishing of textiles, furniture and clothing, various chemicals are utilised to prevent mould and wrinkling and to increase ease of care. These chemicals are released into the air for a long time during their use.
The human metabolism produces carbon dioxide and odours in the air. Stale air, contaminants and strong odours cause allergic respiratory, ocular and other symptoms.
Chemical compounds are used in building materials such as plaster board, mineral wool, paints and adhesives. Due to emissions, for example new buildings have a set ventilation time, which can be several months. The compounds released from the materials, aldehydes and ammonia, often with very strong odours, can cause severe symptoms to the most sensitive individuals.
Particles and gases pass through ventilation and structures : Do you live in a major town or city? Is your office located along a busy main road? Did you know that up to 80% of outdoor air pollutants end up as indoor air through doors, windows and ventilation. Hence vehicle exhaust fumes from outside can continue to worsen the quality of air inside.
Microplastic is formed when plastic waste decomposes. Scientists estimate that by 2050, the Sea will have more plastic than fish in terms of weight. Microplastics are not just a problem in water. The Archipelago Sea Research Institute found that there is also a lot of microplastics in the open air, which is transported into our bodies with the air we breathe.
Room dust is constantly released into the air from workspace surfaces, textiles, furniture, clothing, plants, insects and the skin of people. Room dust is susceptible to indoor air symptoms. Regular, careful cleaning reduces the number of particles, but at the same time it spreads dust from surfaces to the room air.
Many substances used in general cleaning are toxic and dangerous if swallowed and harmful if inhaled. Because detergents are usually handled on a daily basis, they are a significant part of the indoor air hazards in commercial and domestic settings.
Perfumes, shampoos, soaps and other cosmetics are made to please the senses. However, even good scents are allergenic and cause symptoms for sensitised people. Many cosmetics also contain micro-plastics that are harmful to breathing.
Pollen causes allergic symptoms in about one-fifth of people. In addition, global warming has extended the season from February to August. Up to 80% of outdoor air pollutants end up in indoor air through doors, windows and ventilation systems.
Moulds and microbes grow in structures and on the surfaces of building materials when there is enough moisture present. Moisture damage is a major cause of mould problems. Mould spores spread easily in the air and can cause conditions such as allergic rhinitis and allergic alveolitis. Respiratory and skin problems can occur as well as nose bleeds, flu like symptoms, headaches, muscle and joint pain, memory issues and nausea.
Animals are also a burden to the indoor air. Hair, feathers, dandruff and other particles coming of pets, dogs, cats and rodents and birds cause allergy symptoms.
The idea of an Indoor air purifier is that it circulates the indoor air through the machine thus removing pollutants, particles, VOCs, Bacteria, viruses etc. thus returning clean air to the room. This is not only essential for dealing short term pandemics, but also to maintain healthy spaces for the long term.
It is very important to know how much of the pollutants the purifier can remove when the air passes through the machine. This is called filtration efficiency. It can get close to 100%, which is often something that the air purification companies like to promote as it is relatively easy to reach this level. But what really matters is the actual air flowing through the purifier, which is something that is not always talked about. For us to have clean air, filtration efficiency alone does not tell us enough. Only the air circulated through the purifier is filtrated. If only a portion of the room’s air goes through the purifier, the rest stays polluted, no matter how high the filtration efficiency is.
Clean Air Delivery Rate (CADR)
Generally, the whole air volume of a room should be fully circulated through the air purifier at two to five times per hour. The amount of air flow through the machine is as important as the filtration efficiency of the purifier. Because of this the best criteria for selecting a proper air purifier is the Clean Air Delivery Rate (CADR), the amount of clean air delivered per hour (m3/h), which is calculated by multiplying the purifier’s filtration efficiency with the air flow through the purifier.
When it comes to air pollutants, the ultrafine particles are the most harmful as they are most easily absorbed into the lungs. They are also the most difficult to observe with sensors and the hardest ones to catch with filters without compromising on the air flow.
When comparing different CADR values, the filtration efficiency should be measured for the same particle size, preferably for smaller particles
like PM1 or even smaller, not only for PM2.5. Before buying an Air, Purification check your CADR rates are shown and what particles are being measured in that CADR rate.
