How much does it cost to run? Airfree is surprisingly inexpensive considering we spend 90% of our lifetime indoors and Airfree gives us the opportunity to have healthy surroundings.  With Airfree there are no expensive Hepa filters or UV bulbs to replace.  Hepa filters can cost from £40.00 up to £200.00 each per year for some machines with UV bulbs costing around £30.00 each.  This is before you even consider the cost of actually running then units.  Airfree’s extraordinary new technology was specifically designed for 24/7 usage without a jump in electricity consumption.  It will cost you the same to destroy micro organisms in your home as it does to power a single light bulb.
