Filter Based Air Purification: The Dangerous Illusion of Safe Air

The-Dangerous-Illusions-Of-Safe-Filtered-Air

It is no secret that our homes are better built and more comfortable than ever, designed to keep the internal atmosphere at a steady temperature all year round. But where the weather is kept out, contaminants are kept in, and this is a concern for our health.

According to research from the Environmental Protection Agency, people today spend up to 90% of their time indoors, and this is where the concentrations of some air pollutants is highest. In fact, air pollution within the home can be between 2 to 5 times higher than in outdoor settings.

Whilst most people understand the importance of keeping a house clean and free of dust and other visible pollutants, there are lots of other particles and pathogens in the air that we can’t see, from dust mites to pollen, as well as dangerous bacteria and viruses. Together, this creates a worrying combination of hazards that could lead to long-term health problems.

Many people believe that using air purifiers is the ideal way to filter out these pollutants and ensure the healthy environment of the home. But not all air purification systems are created equal, and simply having an air purifier does not mean that your household is safe.

Passive v Active Air Purifiers

There are two types of air purifiers available for home use, which use two main kinds of purification processes. These are:

  • Passive type air purifiers, which are the standard HEPA filters, where the air is drawn into the machine and passed through a filter to remove contaminants, before clean air is released on the other side.
  • Active type air purifiers, that send cleaning agents out into the space to clean the air, and create an ambient atmosphere.

Whilst passive air purifiers are the most commonly used in homes, the fact that the air has to pass through a filter before coming out as clean air means that the process can take a long time, and any new contaminants brought into the atmosphere (such as people coming in and out of a room) make the process take even longer.

On top of this, the trapped bacteria and other pollutants live on in the machine and create a hazard when the filter needs to be changed.

Active purifiers, on the other hand, seek to destroy or neutralise harmful elements in the atmosphere, and work to treat the whole room at the same time, making the process faster and more effective.

Removing Allergens

One of the main reasons that people buy air purifiers for their homes is to protect those that suffer from allergies. Passive air purifiers such as HEPA filters are effective at removing airborne allergens such as pollen, dust mites and pet dander from the space, as they are drawn into the air purifier and trapped in the filter. However, although airborne pathogens are removed, these filters are not as successful at removing allergens from things like your furniture, floorboards and even the foundations of your home, where they tend to settle over time.

Meanwhile, active type air purification systems are far more effective at removing and neutralising these allergens, seeking them out wherever they can be found and destroying them, both in the air and on surfaces.

Area Coverage

Active air purifiers cover a far greater area than passive filter purifiers. This is because a passive air purifier uses a physical filter, through which all air must be passed before it can come out clean. This means that these purifiers are not suitable for larger spaces and will not be very effective.

Active ionic air purifiers can cover a much wider area, some up to 3,500 sq ft, making them suitable for even the largest home or business.

Cost Effectiveness

HEPA air purifiers rely on costly consumable filters and this means that over time they come with a hefty price tag.

Most active air purification systems don’t have any maintenance requirements, save for those which include a collection plate. However, even then, the collection plate is often washable and reusable, and will last for as long as the unit does.

A Healthier Brain

One of the more surprising ways in which clean air affects the body is that it helps your brain to function properly. Studies have shown that air pollution can have a detrimental effect on the human brain, to the extent that people are 30% more likely to suffer a stroke when living in the most polluted countries.

Airius PureAir

The Airius PureAir offers an advanced yet cost-effective solution for those looking for an active air purification system to keep their home clean and safe from pollutants. The system uses an advanced type of oxidation technology called photohydroionisation (PHI) manufactured by RGF Environmental, one of the worlds leading specialists in air, water and food purification, to remove airborne pollutants from a space, as well as neutralising those that have settled on surfaces.

Research has found this type of air purification system to be effective in neutralising the smallest particles of bacteria and other contaminants, which could include everything from the common cold to MRSA, Norwalk Virus, Streptococcus, Bird Flu, Swine Flu, Candida Albicans, and SARS.

What Is Photohydroionisation?

Photohydroionisation is a complex form of oxidation – the process that removes or reduces things like mould, bacteria, viruses, and odours from a confined space by creating clean air through the release of ozone and hydrogen peroxide.

Photohydroionisation works through the reaction of moisture in the air to create hydroperoxides, an ionic reaction that is responsible for the clean air smell we get after a thunderstorm. Using hydroperoxides in the oxidation process accelerates it and makes it more efficient, without some of the safety risks that are associated with other forms of oxidation.

The Airius PureAir series uses the integrated PHI cell to create the photohydroionisation effect using a highly efficient, broad-spectrum UV bulb. This ensures a fast disinfection time over a large cleaning area, effectively clearing the room of allergens and other pollutants within a short period.

For those who want to ensure that their living space remains clean and healthy, and don’t want to run the risks associated with changing filters or keeping bacteria and viruses stored within their homes, this air purification system is one of the best options around today to protect your love ones from these invisible killers.
