Key Takeaways
- Black mould damages property and can cause respiratory issues, allergies, and asthma.
- PIV units introduce fresh air and push out moisture to stop condensation buildup.
- Prices range from £300-£500, with running costs as low as £10 per year.
- Requires only periodic filter changes and basic cleaning.
- Suitable for houses, flats, and apartments, with heated models available to prevent cold air.
In this article we will be exploring how you can limit the danger of black mould with the utilisation of PoziDry PIV units.
What is Black mould?
Black mould is a common property issue caused by the buildup of moisture through poor ventilation and high levels of humidity in the air (condensation).
If left untreated, black mould can seriously degrade the structural integrity and aesthetics of a property. More worryingly, in extreme cases the spores released by this type of mould can lead to potential health issues for occupants.
Black mould can be found anywhere around the home, and is especially prevalent in:
- Bathrooms
- Kitchen/laundry rooms
- Bedrooms
- Attics/basements
What are the specific health risks associated with black mould, and how does it impact occupants?
Black mould can cause respiratory issues, allergies, and exacerbate existing conditions like asthma. Prolonged exposure may lead to more severe health problems.
How can a PIV Unit help?
What is a PIV unit?
A Positive Input Ventilation (PIV) unit is an air introducing appliance that is an extremely effective method of solving mould/condensation problems within properties.
How do PIV units work?
Often loft mounted, a PIV draws in fresh outside air through filters and directs it into the living areas of a property via a small, unobtrusive ceiling grill usually located in a hallway.
The stagnant, moisture-laden air is actually forced out of the house by the pressure of the fresh, dry air being introduced.
This process is continual, ensuring the air within the property is constantly fresh, eradicating condensation and mould growth.
Are PIV units effective?
PIV units, especially premium models such as Vent-Axia PoziDry units, offer the most effective way of halting/preventing black mould growth in a home.
After just a couple weeks after being installed, a PIV unit can produce amazing results in mould control, some customers even claim to have witnessed positive results after only a few days!
Do PIV units take up a lot of space?
No, PIV units are designed to be compact and unobtrusive. Many models, such as the Vent-Axia Lo Carbon PoziDry Compact Pro, are small enough to fit in tight spaces while still delivering excellent performance.
Won’t a PIV make my home colder?
The fresh, dry air being drawn into a property will generally be sourced from outside of the loft/attic area, so technically this could lower the temperature within a home, however, most elite PIV units, such as the Vent-Axia PoziDry Pro Positive are available with their own heater included.
Are PIV units expensive?
PIV units are extremely cost effective. A top-end PIV unit from Vent Axia will often cost in the region of £300-£350. Alternatively you can spend a little more for an Elta model.
An efficient PIV unit runs continuously at a very low speed, this is actually rather inexpensive with running costs being as low as £10 annually!
Can a PIV unit be installed in a flat/apartment?
Yes, many Positive Input Ventilation (PIV) units have the functionality for surface mounting due to anti-vibration legs, meaning no matter the style or size of your home, you’ll never have to compromise on air quality.
Should a PIV unit be installed by a professional?
Professional installation is often recommended to ensure proper placement and functionality. However, some homeowners with electrical experience may be able to install simpler models themselves.
What are the ongoing maintenance?
Yes, Positive Input Ventilation (PIV) units require periodic filter replacement and inspection to ensure optimal performance. It is recommended to change your filters every 12-18 months. Additionally, cleaning the unit and ensuring proper ventilation ducts are essential for maintenance.
PIV vs dehumidifiers
Dehumidifiers and Positive Input Ventilation (PIV) systems both reduce condensation but work differently. Dehumidifiers draw in humid air, condense the moisture on a cooled surface, and collect it in a tray. They are portable, suitable for single rooms, and require regular maintenance, such as emptying trays and cleaning. However, they can be costly to run, especially in large spaces or if used frequently.
PIV systems, on the other hand, provide a whole-home solution by introducing fresh, filtered air that reduces humidity and condensation across multiple rooms. They are energy-efficient, require minimal maintenance, and are ideal for tackling widespread condensation issues.
If your issue is minor and isolated to one room, a dehumidifier may suffice. For more severe or whole-home condensation problems, PIV offers a longer-term, cost-effective solution.
Frequently Asked Questions
How long does it take for a PIV unit to work?
Most homeowners notice a reduction in condensation and mould within a few weeks, though some report improvements within just a few days.
Will a PIV unit make my home colder?
While PIV units introduce fresh air from outside, many models come with built-in heaters to ensure comfort and prevent any noticeable drop in temperature.
Can I install a PIV unit myself, or do I need a professional?
While some basic models can be installed by experienced DIYers, professional installation is recommended to ensure proper setup, airflow efficiency, and long-term performance.
How much does a PIV unit cost to run?
PIV units are highly energy-efficient, with most models costing as little as £10 per year to operate, making them a cost-effective solution for moisture and mould control.
How often do PIV unit filters need to be changed?
Filters should typically be replaced every 12-18 months, depending on the manufacturer’s recommendations and the air quality in your area.
