4. Challenges
It is ironical that modern cars are fitted as a matter of standard with
air filters to protect drivers and passengers, but little is done on a
similar scale to improve healthy air conditions inside our homes
and offices where we spend most of our time at work or leisure. A
simple, straightforward solution for anyone concerned about the air
they breathe indoors is, besides source control, to ensure that the
rooms they are using are well ventilated with clean air or contain an
air purifier.

We know there are many different air purifiers in the marketplace
today, some are frankly better than others at removing airborne pol-
lutants in whatever size or form they come. We fervently believe the
public should be able to make informed choices based on indepen-
dent testing of individual air purifiers by an ethical and well-respected
third party. Air purifiers should be proven to be excellent at removing
harmful indoor pollutants to the highest possible degree relevant to
the size of the room as well as change the entire air in a room at
the rate of five times an hour. All air purifiers should meet at the very
basic level the desire of the consumer for a product that enhances
health and wellbeing at an affordable price.
