PIV (Positive Input Ventilation)
PIV Units Replace The Stale Unhealthy Air in Your Home with Healthy Fresh Air
What is the problem with the air in our homes?
Our modern, sealed homes with double glazing and insulation are more energy-efficient than ever before but they also promote moisture, mould and indoor air pollution.
Pollutants including moisture, cleaning chemicals, mould spores and dust mite faeces can lead to conditions unfit for human habitation.
If you've already tried to cure your mould & condensation issues with more powerful extractor fans, adding sealant all over the place or even just painting over the evidence, you can relax because there is an easier and much more effective solution for you now.
- Indoor air can be up to 50x more polluted than outdoor air
- 17 pints of water can be produced indoors, per day, by a family of 4
- Cooking, bathing and cleaning produce up to 10 litres of moisture per day
- 90% of our time is spent indoors
- We breathe 9,000 litres of indoor air per day on average, so creating a healthy living environment is important to our health
How Does the Unit Prevent This?
Filtered, cleaner, drier air is gently introduced to the home, leading to increased circulation of air around the property.
As air always moves from high-pressure areas to low-pressure areas, cold air is usually pulled in, leaving moisture-heavy stale air in your house. This high moisture content settles onto surfaces in your home which in turn causes all your damp, condensation and mould issues.
Positive pressure ventilation units do exactly what their name says by pushing filtered air into your home creating the pressure which forces the bad stale air out through the existing vents in your home (never cover these up by the way).
Moisture and other pollutants are removed from the air in this way, preventing mould growth.
The unit runs constantly providing consistent high air pressure to ensure that the air in your home is always fresh and free from mould spores, bacteria and other nasties.
Incredible results can be seen just a few weeks after installation of the PIV unit, with reduction or in most cases complete eradication of mould and condensation issues.
The units are available with or without a pre-heater unit that gently warms the filtered air before pushing into your home for additional comfort. These units also include a summer bypass function which automatically switches the heater off during the warmer times of the year. The slightly increased cost of running the heater is offset by your standard home thermostat and also by avoiding the need to open windows during the cold weather to let fresh air in.
By removing the moisture and other air pollutants in this way, mould growth is prevented at the source.
"Mould is a simple plant; if you want to kill it, you must stop watering it!"
PIV Installations are Easier Than Traditional Ventilation Installations
Finding a spot to add a new extractor fan to an already busy home can lead to units being put into an awkward spot spoiling aesthetics or creating noise in an inappropriate area of the home.
Positive Input Ventilation Systems are easily positioned in the loft, mounted on adjustable, vibration-reducing feet. The ducting from the unit connects with a neat grille in the ceiling of your hallway/landing from where it will introduce the clean fresh air.
- Extremely cost-effective as running costs for an entire year can be as little as £5
- Additional F7 filters will also remove pollen and diesel particles. Nox filter models are also available
- With noise levels as low as 9dB(A), the units can hardly be noticed
- Perfect maintenance-free choice for landlords and social housing
