Ford develops a new air filter to help allergy sufferers and to reduce transmission of viruses

  • Ford customers can equip vehicles with an enhanced air filter, capable of trapping the tiny particles of dust, pollen and pollution, to ensure more comfortable travel even for allergy sufferers.
  • Thanks to this system, which uses the common citric acid, easily found in lemons, drivers and passengers are protected from particles that can have incredibly small dimensions, up to less than a thousandth of the thickness of a human hair.
  • Available on the entire Ford range, the filter can also protect against viruses such as swine flu and coronavirus.

Ford offers a filter on its vehiclesenhanced air, able to provide the necessary relief to those suffering from the so-called hay fever and seasonal allergies.

The Ford micronAir proTect filter, developed by Freudenberg’s experts, is highly effective in capturing a wide range of harmful germs, allergens and even viruses, which can cause significant health problems.


The advanced system uses carbon combined with a special active layer obtained from a secret recipe that includes citric acid, present in lemons. This system provides protection against unwanted bacteria, yeasts and fungi, while also offering antiviral properties.

“For many drivers and their passengers, allergies to pollen and dust can cause great discomfort, as well as serious health problems,” said Nigel Brackenbury, Vice President, Ford Customer Service Division, Ford of Europe.” This filter is an economical but effective measure that could protect health and offer greater comfort to anyone traveling in a Ford vehicle.”

How it works

The Ford micronAir proTect is capable of trapping very small particles down to 0.05 microns – less than a thousandth the thickness of a human hair. If mounted on the vehicle’s ventilation system, it can dilute the concentration of harmful particles entering the cabin and remove droplets containing viruses as quickly as possible, reducing the possibility of further contamination and infection.

The filter features an activated carbon element designed to offer additional protection against harmful pollution, such as particles and acid gases, and a multilayer microfiber barrier that retains the smallest particles, dust and pollen.

In addition, the filter acts actively against some agents that are located in the passenger compartment, demonstrating a 99.9% effectiveness in inactivating the viruses that come into contact with the special active layer. (*) These include swine flu (H1N1) and the HCov-229E virus. Current conditions make it too dangerous to test the filter against SARS-CoV-2, the coronavirus that causes COVID-19-related disease, but Freudenberg estimates 99.9% effectiveness in this case too.

Coronaviruses spread in droplets produced when affected people sneeze, cough or breathe and can remain contagious on surfaces for hours or even days. Wind, changes in temperature and humidity can put these particles back into circulation, which, at that point, can be picked up by the filter.


Ford dealers can supply and mount the filter on Focus, Kuga, Mondeo, S MAX and Galaxy, and now also on Fiesta, Puma and EcoSport, while for Transit Courier and Tourneo Courier it will be available by the end of summer.

Ford customers who want to install the Ford micronAir proTect filter can do so with the No Touch maintenance protocols, during which the vehicle is sanitized and protected with additional covers of the contact points, before being returned to the customer.

The Ford micronAir® proTect filter has an anti-viral surface protection developed through the use of a functional filter layer based on fruit extract (active ingredient citric acid CAS-Nr. 77-92-9 and / or 5949- 29-1) for use in air treatment / conditioning systems. Safe bacteriostatic and fungistatic surface protection against a multitude of gram-positive and gram-negative bacteria, yeasts and fungi, as well as proven antiviral properties (Influenzavirus H1N1 and Coronavirus HCoV 229E) according to ISO 18184.
