Why Smell Hound Is Unlike Any Odour Eliminator on the Market
The best odour eliminator isn't the one with the strongest scent — it's the one that leaves no scent at all. Most products are built around fragrance: synthetic perfumes that sit on top of a smell and trick your nose into noticing something else. We built Smell Hound around a completely different premise. Remove what's causing the odour at a biological level, and you won't need to cover anything up.
Chemicals kill all bacteria — good and bad — leaving a void that odour-causing microbes quickly reclaim. We fill that space with beneficial biology that actively crowds them out.
The Science Behind How Smell Hound Works
Our device uses HeiQ Chrisal's patented Synbio® technology — a synbiotic formula that combines prebiotics and probiotics. When it operates, it disperses an ultrasonic micro-mist into the air. That mist contains live beneficial bacteria and the nutrients they need to thrive. Once airborne and settled on surfaces, those bacteria get to work: breaking down and consuming the organic matter — pet dander, urine residue, food particles, mould spores — everything that causes persistent odours.
We call this ambient spatial colonisation. Rather than spot-treating individual areas manually, Smell Hound fills the entire room with biological activity. The good bacteria establish a colony that keeps working for up to 72 hours after a single cycle — and in Auto Mode, our device tops that colony up on a 3-hour schedule without any input from you.
The results have been independently validated. Research by BMA Labor Germany found our Synbio® formula reduces dust mite allergens by 90%, pollen by 60%, and pet allergens by 78%. This isn't a deodoriser — it's an environmental hygiene system.
Our Eco-Friendly Credentials
Our formula is EU Ecolabel certified — one of the strictest environmental standards in the world. It's FDA GRAS listed, 100% natural, non-GMO, and fully biodegradable. When the fluid is washed down the drain, the probiotics continue digesting organic waste in your pipes and greywater system. No toxic biocides, no synthetic fragrances, no harmful residues.
It's safe for children and pets, and carries a 15-year medical heritage — the same technology has been used in European hospitals for over a decade. We brought it to the consumer market in New Zealand and made it accessible for everyday homes and businesses.
Features That Make Smell Hound the Best Odour Eliminator for Everyday Use
→ Auto Mode (flashing green light) — our device dispenses for 10 seconds on startup, then every 3 hours. Set it and forget it. This timing is optimised so a single refill lasts 20–30 days.
→ Manual Mode (solid green light) — press the timer button for continuous dispensing. Ideal for heavy odour events or the initial treatment of a badly affected space.
→ Up to 100sqm coverage — one device handles a large open-plan living area, a commercial kitchen, or a busy retail floor.
→ USB rechargeable — fully charges in under 24 hours; the indicator light shifts from red to blue when complete.
→ Wall-mountable — wall mounts are included so you can fix the unit above 2 metres for optimal mist dispersal across the full room.
→ 2-year refill shelf life — no waste, no pressure, no rushing to use it before it expires.
No other product available in New Zealand combines ultrasonic micro-mist delivery, ambient spatial colonisation, and a certified synbiotic formula in a single autonomous device.
We built Smell Hound because we believed the best odour eliminator should work at the source, not just the surface. And that's exactly what our product does!
