It's Time to Clear The Air

By EnviroVent Oct 26, 2010

Did you know that mould problems and condensation in your home can make you ill and may exacerbate the symptoms of asthma?  And in the winter it gets worse as cold air is less able to hold a given amount of water vapour and so releases this excess water as condensation.

EnviroVent Positive input units can help asthma & allergy sufferers. A recent government report states that 50% of the world’s illnesses are caused or aggravated by poor indoor air. Poor ventilation causes high levels of humidity which in turn increases the levels of dust mites – a known trigger for allergies and asthma.

A ‘viral soup’

As we endeavor  to make our homes more energy efficient with improved building features such as cavity wall insulation, double glazing and draught proofing, ‘natural ventilation’ is prohibited and  a ‘viral soup’  of trapped air with high levels of humidity, mould, dust mites, tobacco smoke and contaminated gases is left inside the home.

Last year a report by The National House Building Council (NHBC) concluded that indoor air may be up to five times more polluted than outdoor air and it warns that indoor air quality is a major environmental health problem.  So as we build tighter homes and continue to ‘seal up’ existing ones the requirement for good ventilation is paramount. Simply opening a window to keep your home well aired is not enough and not always practical.

As the nights draw in, the main priorities for most households will be to keep the home warm whilst making sure that windows are not left open causing security risks. if you ensure your home has the right ventilation from the very start, you’ll be creating a healthy environment which will last for decades to come.  

Innovative solution

UK manufacturer, EnviroVent, designs, manufactures and installs sophisticated whole home ventilation and condensation control units, which are designed to gently ventilate the home from a central position on the landing or central hallway. PIV (Positive Input Ventilation) delivers fresh, filtered and clean air into a property at a continuous rate.  Moisture laden air is diluted, displaced and replaced to control humidity levels at around 55%.  This significantly reduces or eliminates surface condensation, the main cause for mould growth.  What’s more, PIV units help to redistribute heat around the home, thus reducing space heating costs and eliminating the need to open windows. 

The ultra low watt motor technology ensures the systems operate by using the lowest possible energy, reducing carbon emissions. Each product in the Lifetime® Range has been designed to outlast the lifecycle of the property it is installed in and comes with a 5-year guarantee.
