For the first time also with HEPA filter: What modern air conditioning systems can do in the car

Unfortunately we have to stay outside: the view under the hood is denied to the owners of the new Mercedes EQs.Because where other Mercedes models have the engine and electric cars such as the Model S from Tesla a "Frunk" (front drink, i.e. a front trunk), a new air conditioning is sitting at the Swabians.

For the first time, the manufacturer has installed a so-called HEPA filter in the flagship of its battery fleet and thus promises air quality in the luxury liner as in the operating room.The fact that the Swabians sacrifice the additional storage space for this may be able to get over the customers.Finally, the EQs stands out with a classic trunk from 610 to 1770 liters anyway.But it also shows the importance of air conditioning and filtering the interior.

With the surface of 150 soccer fields

"If this was initially a very big issue, especially in Asia, it has also had a top priority in the rest of the world since Corona," says series manager Christoph Starzynski.He justifies the installation of a filter that is larger than a beverage crate and 99.65 percent of the particles of all sizes on a surface with the size of 150 football fields.

Mercedes is not alone in the fight against the thick air in the car.After the developers were concerned with the perfect distribution of air currents in the car for years and about the most individual feel -good zones for every inmate, they are now increasingly wrestling for purity: modern climate systems recognize air quality and automatically activate the air -air operation, they ionize the air flow to eliminate smellsAnd now they are now filtering smaller particles.

Pure air via app remotely controlled

For example, Rolls-Royce launched the first automatic climate automatic climate automatic with a nanoparticle filter in the new Ghost last year, which has also been available for some luxury models at BMW since this spring: "In addition to ultra dustKeeping microbial particles and allergens away from the vehicle inside, "says press spokesman Bernhard Ederer.

In recirculation mode, the interior is cleaned by almost all particles beyond the usual level.And that doesn't even have to be in the car.But thanks to the remote access via an app, the air conditioning system can be programmed accordingly before Fahrberginn.

Mercedes EQS, Rolls -Royce Ghost, BMW Siebener - Pure air is not a privilege of fine society.Last but not least, this proves Honda and presents a new interior filter for his entire model range, which can be bought as an accessories and installed at the dealer.According to their own statements, the Japanese rely on a "multi -layer design that filters and suppresses toxic environmental gases as well as inorganic and biological particles and aerosols effectively."

Don't forget fresh air supply

Nevertheless, they also advise their own initiative, especially in Corona pages.They not only warn above average changes in filters, but also advise too much fresh air: "In order to reduce the risk of infection, it is generally recommended to increase the fresh air supply, as this reduces the concentration of aerosols."On the other hand, if you are traveling in recirculation, you have to rely on the efficiency of the filter system and air exchange when removing the viruses.

Climate systems are now standard down to the compact class, but manufacturers can often still be paid for their high-tech systems.The nanoparticle filter, for example, is only available in a series at BMW in the X7, in seven or eighth it costs surcharge.

Air conditioning can ensure noticeable additional consumption

And even after the purchase, air conditioning can become expensive pleasure, warns Hans-Georg Marmit from the expert organization Küs: depending on the load and performance, air conditioning increases consumption by up to two liters.

However, the money is well invested not only to protect against viruses, pollen and bad smells and to avoid fungal attack in the air tubes of the car: "Especially in summer, activation of the air conditioning is absolutely necessary to the driver's ability to concentrateguarantee."Apart from dehumidifying the air and thus protecting against fitting windows.

But it's not just the manufacturers themselves who want to cause great air and clean air in the car.Since the outbreak of pandemic, there have been numerous air purifiers and spreaders from partly dubious quality that the car want to make the car into clean room at the latest.

From performance, paint and leather to pure air

Even the tuners have taken on this topic.One of them is Rolfhartge from Saarland.Where the company boss Rolf Hartge used to be about performance, paint and leather, he now promises his customers wellness and health.To do this, he equips a Mercedes G-Class to the clean room on wheels.

The cabin of the off -road vehicle not only gets an integrated air purification, but also a microscopically fine surface coating with liquid glass, according to the company: This not only effectively reduces the adhesion of impurities.It should also make viruses, fungi, spores and other pollutants harmless through the antiviral and antibacterial mode of operation.

The manufacturers are doing a lot of effort for pure air in the car, but the driver still has to bring a little bit of their own work, says Küs expert Marmit: "Because air conditioning is only as good as their maintenance," warns the specialist and refers toemphatically on the service intervals of the manufacturers, in which coolant is checked and filters exchanged.

There are your own fragrances

No matter how well a ventilation filters and how thoroughly the owner maintains the air conditioning, it can only suppress or eliminate disturbing smells.Because this does not go far enough for some customers, many manufacturers have long been working with additives and perfuming the interior to match the brand and often to the model.Mercedes also promises not only the pure air in the fleet for the EQS, but also its own fragrance.

Because just like for their convertibles or Maybach models, the Swabians have also composed a special space perfume for the noble e-car: "Number 6 Mood Linen"-the future of Mercedes smells of linen and green coward.(dpa/gem)
