Both air sterilisers and air purifiers are used for cleaning the air of impurities. However, the technologies used in air sterilisers and air purifiers are different.
A simple way to sum up the difference is that air purifiers generally collect unwanted particles in a filter, while air sterilisers actually destroy the particles, including bacteria and viruses.
An air steriliser is convenient and low-maintenance. Due to the sophisticated technologies used in their manufacture, they often come with a slightly higher price tag than filtration-based air purifiers.
Modern homes are practically ‘air tight’, and the lack of ventilation can cause bacteria, viruses, allergens and impurities to build up.
We offer two different types of air steriliser - the Airfree machines and the Radic8 units. Both of these dramatically reduce levels of mould spores, bacteria, house dust mites, viruses and airborne particles, helping you to stay healthy.
The Airfree machines use patented sterilisation technology to incinerate unwanted particles, viruses and bacteria in a ceramic core. They do not emit any particles, ions or ozone.
These are great for mould allergy as they incinerate mould spores rather than simply trapping them in a filter. If you have mould allergy, changing filters can be a source of irritation and may flare up your symptoms. With the Airfree air sterilisers, you don’t need to worry - just plug it in and forget about it!
The Radic8 units work slightly differently; they distribute ‘super oxidants’ into the air, proactively converting impurities into harmless water and CO2. These innovative machines use the photocatalytic oxidation (PCO) technology originally created by NASA. In this process, titanium dioxide is exposed to UV light to kick-start a chemical reaction. Hydroxyl radicals are released into the air, which break down airborne pollutants like allergens, smells and viruses. These impurities are changed into a harmless combination of carbon dioxide and water.
The Radic8 air sterilisers do require replacement bulbs for maintenance. The 200 and 250 models are absolutely silent. The 300 contains a fan so produces a small amount of noise.
Radic8 air sterilisers not only tackle allergens - they also come into their own when it comes to halting the spread of bacteria and viruses. We have one in The Healthy House office, and nobody has caught a cold from a colleague in years.
Don't forget room size
When choosing an air steriliser, make sure you check the recommended room size, to ensure it will clean your air effectively.
