Healthy living – avoid mold, live healthily for the long term

Identify causes, actively purify the air – for mold-free and hygienic living spaces

Mold is not just a visual or structural problem – it poses a serious health risk. Even low concentrations of mold spores in the air can lead to respiratory diseases, allergies, asthma, or chronic infections. Children, seniors, and immunocompromised individuals are particularly affected.

oxytec‘s air purification solutions prevent mold growth through controlled hygienic air exchange, dehumidification, and germ reduction using UV-C technology.

Common causes of indoor mold

Cause Effects Solution with Oxytec
Insufficient ventilation Moisture accumulates → mold growth Hygienic air exchange with germ-free supply air
Cold exterior walls, thermal bridges Condensation forms on surfaces Dehumidification, even air distribution
Airtight building envelope (e.g., KfW) Moisture remains in the room Recirculating air purification, disinfection, promoting air exchange
Invisible sources of spores (e.g., furniture, carpets) Pollution of the air we breathe UV-C air purification neutralizes spores in the air

Why use Oxytec to prevent mold?

Germ-free air actively reduces the risk of mold
Odorless living spaces – no musty smell
UV-C technology deactivates spores in the circulating air
Solutions for every living situation: from old buildings to passive house apartments
No chemicals – safe even for children’s rooms and bedrooms

FAQ – Frequently Asked Questions

How exactly does Oxytec help prevent mold in living spaces?

Our systems combat mold on two levels:

  1. Reducing humidity through hygienic air exchange
  2. Neutralizing mold spores in the room air with UV-C technology

This not only prevents growth, but also reduces the health risk posed by spores.

Can air purification alone prevent mold growth?

It makes a decisive contribution, but must supplement structural deficiencies, not replace them. The ideal solution is a combination of:

  • hygienic ventilation or recirculating air purification
  • Structural mold protection (thermal insulation, moisture protection)
  • Avoidance of thermal bridges and condensation

What happens to mold spores in the air?

UV-C light deactivates the spores – they can no longer multiply. Our devices clean the air without filters, meaning:

  • no recontamination
  • no spore deposits in the device
  • no follow-up treatment necessary

How loud are the devices during continuous operation?

Our recirculation units and modules for living spaces are whisper quiet – usually

  • less than 35 dB(A) in normal operation
  • also suitable for bedrooms or children’s rooms
  • quieter than typical room air purifiers with HEPA filters

Can Oxytec also be combined with ventilation systems?

Yes, especially with controlled residential ventilation (CRV):

  • UV-C modules for supply air or recirculation circuits
  • Suitable for retrofitting or new installations
  • Can be used in addition to heat recovery

How maintenance-intensive are the systems?

Very low:

  • No filter replacement necessary
  • Maintenance of UV-C tubes approx. once a year
  • Maintenance can be carried out by in-house technical staff or a specialist company

Are there any legal requirements for mold prevention?

Yes. Particularly relevant:

  • DIN 1946-6: hygienic air exchange to prevent moisture
  • VDI 6022: Hygiene in indoor air systems
  • WHO limits: for mold spores and VOCs

oxytec helps to comply with or even exceed these requirements.

Is the use of air purifiers to combat mold encouraged?

In some cases, yes:

  • For renovation measures in residential construction (e.g., KfW programs)
  • In nursing homes, allergy-friendly apartments, kindergartens
  • Funding applications often require technical documentation—we are happy to provide this.
