The NHS Blames Damp and Mould for Respiratory Problems

Damp damages more than your property, it damages your body too.

The NHS warns that “…if you have damp and mould you’re more likely to have respiratory problems, respiratory infections, allergies or asthma. Damp and mould can also affect the immune system.”

As well as eliminating damp, PIV units filter allergens out of the air and can significantly improve quality of life for people suffering from asthma or other breathing problems.

How do PIV units work?

  • Air moves because of air pressure, flowing from areas of high pressure to low pressure.
  • By creating higher air pressure in your home than outside, air is forced out, along with any moisture it carries.
  • PIV units can either pull air from your loft or through an external wall.
  • As the PIV unit only consists of a single fan, the running cost is pennies day.
