PIV Servicing and Filter Cleaning – Keeping Fresh Air Flowing Through Your Home

But like any bit of ventilation equipment, your PIV system needs looking after to keep doing its job properly. As your local extractor and ventilation specialist in Bradford, I carry out PIV servicing and filter cleaning to make sure your system keeps running smoothly and efficiently — without letting dust or dirt clog things up.

1) What is a PIV system?

A PIV (Positive Input Ventilation) system works by gently introducing filtered, fresh air into your home — usually from a central unit fitted in the loft space. It helps push out stale, humid air while balancing humidity levels, reducing condensation, and stopping black mould before it starts.

It’s a simple but clever way of ventilating your home. You’ll often find them in properties that struggle with condensation or older homes that have been upgraded to improve insulation and energy efficiency.
PIV systems are fantastic when they’re maintained properly — but they do need attention from time to time to make sure they’re doing their job right.

2) Why servicing your PIV system matters

Over time, the filters inside your PIV unit naturally start to collect dust, pollen, and fine particles. That’s their job — but when they get clogged up, airflow drops, and the system can’t push enough clean air into your home.

You might notice the air feels stuffier, or condensation has started appearing again on your windows or mirrors. That’s a sign your PIV could do with a service.

Regular servicing keeps the fan and filters clean, makes sure the controls are working properly, and checks that air is being distributed evenly throughout your home. It also helps keep your energy use down, as a clogged unit will work harder and use more power than it should.

3) What’s included in a PIV service

When I carry out a PIV service, the focus is on giving the system a thorough clean and making sure it’s doing what it’s meant to — delivering a steady flow of clean, filtered air into your home.

Here’s what’s typically included:

• Filter replacement – Depending on condition and manufacturer’s guidance.
• Fan and motor inspection – Making sure the fan runs freely and quietly.
• Ducting checks – Ensuring air is flowing properly through the vents.
• Airflow and heater test – I’ll test that the airflow is as it should be, and check that the heater (if fitted) is operating correctly.

The main focus is on keeping it clean, checking that the fan and filters are in good condition, and making sure the airflow and heat are working as they should.

4) How often should you service your PIV system?

Most manufacturers recommend a full PIV service every five years, but it’s worth keeping an eye on the filters in between. If you can see that they’re clogged with dust or dirt, it’s a good idea to get them cleaned or replaced sooner.

If your PIV has a built-in heater, you’ll also want to make sure it’s still working correctly, especially over winter.

As with any ventilation system, regular checks and cleaning will keep it running efficiently and help stop condensation and stale air from building up in your home.
