This air purifier has an advanced 7 stage filtration system to remove 99.97% of all airborne pollution, allergens, smoke, harmful gases, and odours – creating a healthier atmosphere.
It is ideal for a room up to 35m² (87.5m³).
The first stage of air cleaning is the washable nylon filter, which retains larger particles including human and animal hair, pollens and dust fluff.
The air then passes through a HEPA (High Efficiency Particulate Air) filter where 99.97% of particles >0.3 micrometres is removed. For comparison, a hair has a width of 70-100 micrometres.
Originally the HEPA filter was developed for use in clinical applications and is now a breath of fresh air for allergy sufferers.
Once the small particles have been removed, an active carbon filter removes harmful gases and odours.
The fourth stage of the filtration process is the Cold Catalyst filter Biostop-2 which breaks down toxic emanations of the VOC type. VOC (Volatile Organic Compounds) are found in building materials such as gloss paint, varnish and deodorant; as well as in household cleaning products. The Biostop-2 is a cold catalysis filter: a new method of breaking down toxic emanations making them harmless enough to breathe.
Stage five and six is an UV lamp and photo catalyst TiO2 filter that kills any remaining airborne bacteria, reducing the impact of germs and viruses. The UV lamp can be turned off and on when the unit is operating.
The final stage of the filtration process is an ioniser this will replace negative ions that have been destroyed by pollution and electronic equipment. Air contamination and electronic appliances such as computers and televisions lead to the breakdown of negative ions in the air. When there are not enough negative ions, the air feels stale and stuffy. By generating negative ions the air feels noticeably clean and fresh.
This unit has exceptionally quiet operation compared to other HEPA air purifiers on the market.
The LED control panel includes an on/off button, three fan speed settings (low, medium and high). All controls can for the air purifier can be controlled by the remote control.
As indoor air can quickly become contaminated by activity in the room it is advisable that the air purifier should operate 24 hours a day as it uses just 35W it is cheaper to run then a standard light bulb.
Regular filter replacement is a prerequisite for hygienic, trouble-free operation. The HEPA and carbon filter would need to be replaced every 3 months. The catalytic filtration (cold catalyst filter, UV lamp and photo catalytic filter) would need to be replaced once a year.
