Types of PIV Units We Supply & Install

At ClearAIR PIV, we supply and install a variety of Positive Input Ventilation systems. All installs we undertake are tailored to suit different property types, layouts, and air quality concerns. Here’s a breakdown of the main types we offer:

Loft-Mounted PIV Units (For Houses with Loft Space)

Loft mounted PIV units are our most popular solution. This is due to them being discreet, but effective. Loft mounted PIV units are ideal for houses with an accessible loft space. 

These systems draw in fresh, filtered air from the loft. Then distribute it into your home or place of work.

Wall-Mounted PIV Units (For Flats & Bungalows)

Our wall-mounted PIV units are designed for properties like flats, apartments, bungalows. These units are compact, versatile, and installed directly on an internal wall. These PIV units are perfect for properties without a loft space but are still suffering from condensation or poor air quality. 

Heated PIV Units (With Integral Heater)

A heated PIV unit comes equipped with integral heating elements. These systems gently warm the incoming air before it’s filtered into your home or place of work. This makes them a great choice for homes in colder climates. Heated PIV systems are especially popular with landlords and homeowners who want to avoid cold draughts.


Tailored to Your Property

Every home is different, which is why we don’t take a one-size-fits-all approach. Our ventilation assessors will visit your property and recommend the right PIV unit based on:

  • Property type and layout
  • Airflow and ventilation levels
  • Presence of condensation or mould
  • Whether there’s access to a loft space

We can supply and install a system that fits your home and budget.
