Improved Indoor Air Quality

Improve Indoor Air Quality At Home
Breath Easy With ClearAIR PIV.

Many homes across the UK suffer from poor indoor air quality. You may not see it, but it can affect your health, comfort, and even sleep.

At ClearAIR PIV, we help homeowners and landlords improve indoor air quality using Positive Input Ventilation (PIV) systems. These units gently remove stale, polluted air and replace it with fresh, filtered air.

What Affects Indoor Air Quality?

Poor indoor air quality happens when high levels of stale or damp air becomes trapped inside indoor spaces. In modern homes, insulation is tight, and windows stay shut. While this saves energy, it also locks in moisture, pollutants, and allergens.

Common causes include:

  • Cooking fumes
  • Cleaning chemicals
  • Mould spores
  • Pet dander and dust mites
  • Smoke or odours
  • Moisture from bathrooms or drying clothes

Without proper airflow, these particles build up. This leads to musty smells, condensation, and even respiratory infections. People with asthma or allergies often suffer the most.

Why Indoor Air Quality IAQ Matters

Clean air in your home or place of work supports better health, sleep, and wellbeing. 

Poor air quality has been linked to health problems like headaches and fatigue. Breathing issues and asthma flare-ups can often be triggered by poor indoor air quality. Even skin irritation and poor sleep can be linked to bad air quality resulting from damp and mould growth.

Children, the elderly, and those with health conditions are most at a health risk. That’s why more homeowners and landlords are turning to ventilation systems that actively improve indoor air quality.

How a PIV System Improves Indoor Air Quality

At ClearAIR PIV, we use Positive Input Ventilation (PIV) systems. These units work quietly in the background to improve airflow and reduce moisture.

Here’s how it works:

  1. The unit draws in fresh, filtered air from outside or the loft
  2. This air is gently pushed into your living spaces
  3. The fresh air replaces stale, damp air reducing indoor pollutants
  4. Moisture, allergens, and other sources of pollution are flushed out

The result is a  drier, cleaner home with improved indoor environment and air quality for the inhabitants. These units are perfect for homeowners, property managers and landlords.

Do I Need A PIV For Improved Air Quality?

Excess condensation can cause mould to appear in the corners of your rooms or behind furniture. These rooms will feel damp, cold and have a strong musty smell coming form them.

These are all signs that your home’s ventilation isn’t working properly. This can lead to problems arising with the air quality in your home. If left untreated it can also lead to potential health risks to you and your family. Our PIV systems are designed to fix these issues by improving air circulation, reducing indoor humidity and improving air quality.
