Indoor air can have levels of certain pollutants up to five times higher than outdoor air. A recent report suggested that indoor air pollution kills up to 40,000 people per year in the UK. On top of this, we spend up to 90 percent of our time indoors.
Activities such as cooking and cleaning can emit many chemicals into the air. Pets can add to allergens in a household and so can chemicals from carpets and certain furnishings.
This can create a toxic and unhealthy mix which can cause health issues or greatly exacerbate existing ones such as allergies, asthma or other respiratory diseases.
Air purifiers, or portable air filtration systems, can remove indoor air pollution and can create a cleaner indoor air quality. This can result in real benefits especially for people living with allergies or asthma. There are many different types of air filters and purifiers and some work differently.
High-efficiency particulate air (HEPA) is an efficiency standard of air filter. Filters meeting the HEPA standard must satisfy certain levels of efficiency.
HEPA filters are designed to remove 99.97 % of all air borne pollution down to a level of 0.3 microns. There are high grade HEPA filters that can go up 99.999 %
Some sizes of pet dander can be 90 microns, pollen can be 30 microns, dust mites are around 10 microns, tobacco smoke is approximately 1 micron and HEPA filter standers is 0. 3 microns.
So, it is clear to see that HEPA filters are efficient at removing small airborne particles in the home.
An air ioniser is a device that uses high voltage to ionise (electrically charge) air molecules. Couples with electrostatically positively charged collector plates, they have been used to eliminate the occurrence of airborne bacterial infections and lower airborne viral infections. Air ionisers are used in air purifiers to remove particles from air. Airborne particles become charged as they attract charged ions from the ioniser by electrostatic attraction. The particles in turn are then attracted to any nearby earthed (grounded) conductors.
PHOTO CATALYTIC AIR PURIFIERS
In photocatalytic air purifiers, the catalyst that cleans the air is typically titanium dioxide and it is energized by ultraviolet (UV) light. The ultraviolet light shines onto a catalyst, which converts water in the air into a form that turns molecules of pollution into more harmless substances.
Unlike filters which trap air substances, photocatalyst air purifiers completely transform the harmful chemicals and effectively destroy them.
The only drawback is that during the processes of the photocatalytic purification tiny amounts of ozone (O3) can be produced. Purifier makers claim the amounts of ozone produced are well within the guideline limit (0.05 parts per million) but this is something to keep in mind.
ULTRAVIOLET LIGHT AIR PURIFIERS
UV air purifiers use short-wave ultraviolet light (UV-C light) to inactivate airborne pathogens and microorganisms like mould, bacteria and viruses. They are used to reduce indoor air pollutants. In UV air purification systems, the extra energy emitted from the UV light can change the molecules that absorb it, and DNA is particularly susceptible to these changes. Ultraviolet light bombards microorganisms around the UV lamp and damages the DNA they need to live.
WINIX have developed Plasmawave® technology and use this in their air purification units.
How it works:
- The PlasmaWave® air purifier technology in our Air Purifiers creates a short electrical discharge to create dual polarity ions from air moisture that are dispersed into the This electrical discharge is safe and only occurs for a short period of time (nanoseconds).
- These are + hydrogen (H+) and – oxygen ions (-O2). The ions attach themselves to surface of air pollutants to form Hydroxyls by removing hydrogen from the structure of air
- This interaction removes air pollutants and allows the ions to use the missing Hydrogen ion, which was removed from the structure of the air pollutants, to return as air moisture (H2O).
Benefits of Plasmawave® technology.
-Greatly reduces odours from everyday smells such as bodily, cooking and smoke
-Protects indoor air by reducing mould growth rates.
-Increases air purification performance by reducing static electricity so air pollutants are captured by the air purifier airflow directing them into the multi-stage filtration process.
