What is PIV & How Does it Work?
Positive Input Ventilation (PIV) system is a cost-effective, low-maintenance way to reduce condensation. Stop black mould. But most importantly improve air quality. With better house ventilation in your home, a PIV unit gently pushes out stale, damp air. Then replace it with fresh, filtered air. All day, every day.
No more wet windows. No more musty smells. Just cleaner air for you and your family.
Signs Your Home Needs Better Ventilation
Many homeowners don't realise their property has ventilation issues until problems become serious. Common warning signs include: water droplets forming on windows and mirrors, musty or stale odours that won't go away, black spots appearing on walls or ceilings, and clothes or soft furnishings feeling damp.
You might also notice increased allergy symptoms, disturbed sleep, or that your home feels stuffy even with windows open. These are all indicators that your home's natural ventilation isn't sufficient.
A PIV system addresses these issues at source, creating a healthier living environment for you and your family whilst protecting your property investment.

The service that we received from ClearAir PIV and Steven himself has been excellent. We have been looking into PIV systems for a while as we have had such a problem with condensation on our bedroom windows. As soon as the temperature begins to drop each year the windows are covered. It has ruined the decor around the windows and caused mould to grow on the frames. Having spoken to Steven on the phone I could tell had specialist knowledge in the area. There was no hard sell, just advice. I got him booked in the same week to fit an Nuaire PIV and I’m so glad we did. Fitting was done quickly and cleanly by John who was friendly, well presented and very knowledgeable and experience in ventilation systems. Steven came too to give advice on another issue we had discussed on the phone. Result: NO MORE CONDENSATION!!! I thought it might take a few days to clear the moisture, but the next morning we checked the windows when they would normally be soaked and… nothing! And nothing since! So happy! I’d read in some reviews of the PIV systems that they were noisy and made the landing cold. This is not my experience. I honestly can’t hear it and although the landing may be ever so slightly cooler, the overall temp of the house isn’t effected and it’s not anything I’m concerned about.

Excellent Service and Results! I recently had a new PIV system installed in my home, and I couldn't be happier with the outcome. Communication with Steven was excellent from start to finish — he responded immediately to any queries and kept me informed throughout the entire process. The installation itself was smooth and professional. Since having the system installed, I’ve had no issues with mould or condensation — a huge improvement! I would highly recommend Steven and his company, CLEARAIR PIV Ltd. Reliable, efficient, and effective service.
