What Is Bipolar Ionisation?
How Bipolar Ionisation Works (In Plain English)
How Bipolar Ionisation Works (In Plain English)
Bipolar Ionisation (BPI) is a natural‑mimicking air‑cleaning process that releases positive and negative ions (tiny charged particles) into your indoor air. These ions attach to airborne contaminants—dust, pollen, smoke, odours, and microbes—and help neutralise them. The result is cleaner, fresher air throughout the room, not just at the filter.
Safety first: Our BPI is ozone‑free, designed for continuous use in occupied homes without harmful by‑products.

How Bipolar Ionisation Works (In Plain English)
1. Ion generation: The unit produces balanced positive (H⁺) and negative (O₂⁻) ions into the space.
2. Particle reduction: Ions cluster tiny airborne particles (PM) so they become larger and are more easily captured—or settle out of the breathing zone.
3. Pathogen disruption: Ions interact with the surface of viruses, bacteria and mould spores, stripping away hydrogen atoms that help stabilise their structure. That disrupts their integrity, reducing their ability to infect or reproduce.
4. Odour & VOC reduction: Reactive species formed in the process can break down odour‑causing molecules and some VOCs, improving indoor freshness.
The Deeper Science (Short, Clear & Useful)
How Bipolar Ionisation Works (In Plain English)
Why Ionisation Alone Isn’t Enough for Damp & Mould
Charged ions seek equilibrium. When they meet a contaminant, they either neutralise it chemically (by oxidising/reducing bonds) or physically (by agglomerating particles together).
Hydrogen abstraction: Removing hydrogen from proteins or lipids can alter shapes of viral proteins or bacterial membranes, reducing viability.
Whole‑room action: Because ions disperse through the air stream, BPI works beyond the appliance, reaching nooks and corners where simple filtration often struggles.

Our Unique Advantage: Ionisation + Tankless Dehumidification
Why Ionisation Alone Isn’t Enough for Damp & Mould
Air cleaning improves air quality, but damp and mould are fundamentally moisture problems. If relative humidity (RH) stays high, surfaces reach dew point, condensation forms, and mould can thrive, no matter how clean the air is.
That’s why our approach pairs ozone‑free BPI with active, tankless dehumidification.

Meet the IW25‑5 On‑Wall Dehumidifier (with Ozone‑Free BPI)
Actively removes moisture (up to 33 L/day*), so RH is held within safer ranges.
Prevents condensation on cold surfaces (windows, external walls, corners).
Cuts the fuel‑poverty risk: Even when heating is off or reduced, the IW25‑5 keeps RH under control—helping prevent damp and mould.
Quiet, installed, hands‑free: Tankless drain (gravity or optional pump) and an integral humidistat that automatically maintains RH.
Plus cleaner air: Ozone‑free BPI reduces fine particles, odours and microbial load.
*Performance varies with temperature, humidity and room layout.

How the Combo Works Day‑to‑Day

Sense & control: The humidistat monitors RH.
Dehumidify: When RH rises above the set point, the unit condenses and removes water vapour from the air, lowering RH and dew point.
Re‑condition & return: Air is gently reheated and circulated back into the room.
Clean as it goes: The ozone‑free BPI module continuously sends ions into the space to reduce airborne particulates, odours and microbes.
Result: Dryer air + cleaner air—exactly what damp and mould prevention needs.

We’re often asked how our approach compares to solutions which uses hydroxyl, and HEPA to clean air.
Where we’re similar
Both aim to reduce airborne contaminants (microbes, odours, particulates).
Both are suitable for occupied spaces and offer whole‑room air improvement.
Where we’re different—and why it matters
Moisture removal: Hydroxyl devices do not actively dehumidify.
Condensation prevention: Without moisture removal, condensation can still form, especially in cold rooms or when heating is off (fuel poverty).
Root‑cause focus: The IW25‑5 removes water vapour, controls RH, and prevents damp and mould from taking hold, while simultaneously cleaning the air.
Installed, continuous protection: Our tankless, installed solution provides hands‑free, ongoing prevention, not just temporary air treatment.
Bottom line: If the problem is damp & mould, you need humidity control. The IW25‑5 delivers humidity control + air cleaning in one robust, low‑disruption system.
