Like most homeowners, you’re probably concerned about mould creeping into your home. It’s an understandable fear – aside from being unsightly, mould can pose serious health risks and create a breeding ground for unwanted pests. Preventing and eliminating it is key to creating a healthy, comfortable living space.

Positive Input Ventilation (PIV) systems have gained popularity as a potential solution to mould problems, but do they actually work? Well, that’s what we’re here to answer.

As damp and mould experts, the Prokil team know the ins and outs of creating a mould-free home. Read on to find out how PIV systems work and how effective they are at tackling mould!

What is a Positive Input Ventilation system?

A PIV system is a whole-house ventilation solution designed to improve indoor air quality by introducing fresh, filtered air into your home. Here’s how it works:

• A PIV unit typically located in the loft or on a wall draws in fresh air from outside.
• This incoming air is filtered to remove pollutants and allergens.
• The filtered air is then gently distributed throughout the home, creating a positive pressure.
• This positive pressure forces stale, moist air out through natural gaps in the building.

Can a Positive Input Ventilation system help prevent mould?

Absolutely!

When warm, moist air from activities like cooking, showering, or drying clothes comes into contact with cold surfaces, condensation forms. This moisture can create damp spots on walls, windows, and other surfaces. If mould spores in the air settle on these damp areas, they find the perfect conditions to multiply and grow.

PIV systems bring fresh, dry air into your home, lowering humidity by pushing out damp air. This makes it harder for condensation to form, reducing the chances of mould appearing.

Can a Positive Input Ventilation system remove existing mould?

While PIV systems are great at preventing mould, they can’t eliminate mould that’s already there. Mould can only be removed by cleaning the affected surfaces with a specialised cleaner, identifying the source of the damp conditions, and taking steps to prevent the damp from returning.

Although some minor mould cases can be handled on your own, it’s usually best to call in a professional for anything more extensive. Mould can penetrate deeper than what’s visible on the surface and requires comprehensive cleaning to make sure nothing is left behind, as leftover patches could continue to spread. A specialist can employ advanced tools and techniques to thoroughly remove the mould and address the root cause of the damp, whether that means installing a PIV system, adding a new damp proof course, or taking other necessary measures.

Is it worth installing a Positive Input Ventilation system?

A PIV system won’t banish mould that’s already there, but it’s a great way to stop it from appearing in the first place. This makes it a smart choice for preventing damp and mould problems. It also cleans the air of pollutants, allergens, and dust mites, creating a healthier home environment overall.
