We spend an average of an hour a day in our cars. With air pollution inside vehicles commonly several times higher than outside, we can absorb 20 – 25% of our total pollution exposure whilst driving. So when it comes to vehicle air purifiers, we don’t believe in style over substance. It’s what’s on the inside that counts.
Take the MobileAir, solidly engineered in powder-coated aluminium, from AllerAir in Canada, who have made nothing but functional, reliable air purifiers for 22 years.
We don’t apologise for its mundane appearance because MobileAir‘s job is to sit on the floor of your car and clean the air very, very well. As far as we know it’s the most effective car air purifier in the world. It removes almost every unwanted particle that passes through it, extracts the polluting gases that ordinary filters cannot, and it keeps on doing so for year after year. We guarantee a life-time availability of filters; not that you’ll need too many, as with up to 20 times the capacity of its distant competitors, MobileAir filters will normally last for three years.
Dimensions: 25 x 20 x 7 cm. Weight: 1.8 kg
Total cost of purchase and new filters for 6 years of clean air = 25p/day.
MobileAir is supplied with two sets of Velcro™ hook & loop strips.
We recommend that you fix the two hook strips – the fluffier ones – to the base of the MobileAir, near the end edge of the unit. If installing the unit under one of the front seats onto the carpet this will suffice to hold the unit in place during normal operation and allow for easy removal or replacement when preferred. The hooks will grip the carpet.
If installing the MobileAir in the boot of a hatchback, 4x4 or estate, you may prefer to fix it to the side of the boot compartment. To do so, fix the loop strips to the side of the vehicle in the desired location. Press down firmly on the strips and leave for a few hours before attaching the MobileAir to ensure a good bond. Apply the same process for other, un-carpeted installation areas.
As you may wish to move the MobileAir from time-to-time, depending on passenger comfort, we have supplied 2 sets of the loop strips for convenience. When moving the unit to another location take care not to pull the loop strips off the vehicle unintentionally.
Top quality purifiers often boast of their use of ‘HEPA’ (High Efficiency Particulate Absorber) filters, defined as able to remove 99.97% of particles larger than 0.3 microns (really very small – a single human hair is around 250 times as thick). Less reputable brands may talk of ‘HEPA-like’ filters which is jargon for ‘Not a HEPA filter but you probably won’t know’.
The smaller the particle, the more readily it can get into your lungs and your blood stream, ending up inside your cells throughout your body.
The MobileAir contains two layers of Super HEPA – acting as a barrier to 99.99% of particles as small as 0.1 microns – or 1/10,000 of a mm. Unlike traditional pleated HEPA filters Super HEPA is not manufactured with glues, binders or fibreglass and is ideal for users with chemical sensitivities.
The ONLY way to remove significant quantities of gaseous pollutants is with activated carbon. The source of the carbon, the method used to activate it, the size of particle, and various chemical processes all affect how well the filter will remove different polluting gases from the air.
The MobileAir uses Vocarb - a proprietary blend of carbons especially engineered to have the maximum effect on both nitrogen dioxide (NO₂) , the chief gaseous concern from diesel emissions and the numerous VOC’s (Volatile Organic Compounds) given off by vehicle interiors and which react with N0₂ to form equally hazardous ozone.
Many purifiers claiming to have carbon filters contain just a few grams of a standard carbon. Not only is the exact type of carbon important but these filters work by attracting the gases to their surface, so the more carbon, the better the filter and the longer it will last. Many alternatives MobileAir contains a massive 2 lbs (900 g) of bespoke activated carbon granules, to create the longest lasting, most effective purifier on the road.
In general use the filters in a MobileAir will need replacing after 3 years. However, in the heavily-polluted environment of a new car (yes, sorry) we strongly recommend changing the filters after the first 9 months.
