Air filters for best indoor air quality against air pollution

Make sure your indoor air is free of pollutants and viruses. Upgrade your existing HVAC system or install air purifiers with certified HEPA filters.


When we think of air pollution, we usually think of poor outdoor air quality: cities under smog clouds, industrial areas and high traffic roads. But indoor air pollution is actually worse – sometimes as much as five times higher – than outdoor air pollution. As we spend around 90% of our lives indoors, bad indoor air quality can significantly impact our health, productivity and social interactions. Which is why good indoor air quality is so important.

MANN+HUMMEL offers numerous solutions for cleaner indoor air quality (iaq). Our filtration solutions can improve indoor air easily, quickly and sustainably. From upgrading your existing room air technology to fitting modern, mobile room air purifiers with HEPA*-H14 filters, our products ensure cleaner, healthier room air – anywhere and any time.

How is indoor air pollution caused?

The sources of air pollution

Unfortunately, thick walls do not protect interiors from air pollution. Poor indoor air is caused by:

  • People bringing in pollutants like fine dust or pollen from the outside.
  • Common indoor air pollutants like tiny particles of skin, hair and clothing.
  • Carpets and other furnishings, cleaning agents, paints, glazes and much more that release harmful gases or volatile organic compounds (VOC).
  • Pets carrying particles or allergens.
  • Oxygen consumption causing CO2 levels to exceed the recommended limit (around 1000ppm) for indoor air.
  • Regular ventilation – especially in places with bad outdoor air quality – which can let pollutants like fine dust and harmful gases like ozone into the room.

Evidently, the air quality in buildings, whether it is in the workplace, in schools or at home,  can be negatively influenced by many different factors. All we need for optimal room air that meets the international indoor air quality standards is uncompromising, highly effective and sustainable solutions against air pollution.

Move onto the next level: HEPA upgrades for existing HVAC systems

Our upgrade options for existing heating, ventilation and air conditioning systems include standard filter elements, filters with biofunctional coatings and modern HEPA room air filters.

Upgrading existing HVAC systems to HEPA filters is particularly worthwhile if you want to improve your indoor air quality. With a filtration performance of up to 99.995%, HEPA filters (H13 and H14) serve as highly effective pollen filters, fine dust filters and protective shields that filter acute threats such as COVID and other viruses or bacteria from the air.

The advantages of a HEPA upgrade for indoor air quality systems at a glance:

  • The upgrade saves money and time with no decrease in pressure drop or need for reconfiguration.
  • Even with the upgrade your energy costs remain roughly the same as before.
  • You can provide cleanroom level air quality.
  • With our filters you can operate your building safely and protect guests, customers, employees or family – in the long term and holistically.
  • Our filters meet all safety requirements, in particular the fire protection regulations according to EN 15423 or VDI 3803-4.
