Maintenance MVHR (probiotics)

Cleaning MVHR unit with bacteria

An MVHR ventilation system keeps the indoor climate healthy. Fresh air is supplied, while moisture and dirt are removed. Want to make the most of it? Then opt for regular ventilation maintenance by a professional. What is a heat recovery system? And how does it work?


Benefits of ventilation system maintenance

Super-bacteria are a growing public health problem. They are resistant to antibiotics and disinfectants. What's more, they return in greater numbers after cleaning with chemicals. With probiotics, however, they can be effectively combated. In this way, they make an important contribution to the maintenance of MVHR units and help to maintain a healthy indoor environment. But maintenance is more than just cleaning the unit. It is also important to check all the mechanical components of the ventilation system.

How often should an MVHR-unit be cleaned?

  • Twice a year: replace filters. Easy to do yourself. Use a refreshing spray to protect the MVHR filters against bacteria
  • Annually: Basic Maintenance
  • Every two years: Extended Maintenance
  • After 7 years: MVHR-ventilation duct cleaning

What are probiotic cleansers?

In soil, water, air and the human body: microorganisms are everywhere. There are billions of them, and they have only one goal: to survive. Fortunately, most of them are good for us. For example, they provide digestion, compost or food such as wine and cheese. A small group of microorganisms are harmful to humans, animals and the environment because they cause disease and spoil food. These pathogens are usually controlled with chemical detergents, but superbugs are becoming increasingly resistant to them. Fortunately, there is an alternative: probiotics. Probiotic cleaning products have been formulated with bacteria that naturally fight pathogens. A natural solution to a natural problem.


Good for people, animals and the environment

Probiotics are extremely effective in neutralising superbugs. Probiotic cleaners are therefore very suitable for cleaning MVHR units. Odour molecules are absorbed, preventing odours. Probiotic cleaners are also safer to use than chemical cleaners. They are also useful after use, as they help to purify waste water. In short, a super result against super bacteria.


Replacing an MVHR

Ventilation maintenance optimises the life of your system. However, the fact is that every ventilation system needs to be replaced at some point. Do you have an MVHR system that is 15 years old or older? Have you noticed that air quality is deteriorating, energy consumption is increasing and/or the system is making more noise? Then it's time to replace your air handling system. Want to know more? Then read more on ‘Replacing a ventilation system’.
