You've Cleaned Everything. Scrubbed Everything. And It Still Smells.
You know the feeling. Guests are coming. You've cleaned for hours. You light a candle, crack a window, spray half a can of air freshener... and 20 minutes later, it's back.
That lingering smell isn't a surface problem. It's embedded in your carpets, curtains, couch cushions, and walls. It's bacteria, pet dander, cooking residue, and moisture - all creating a cocktail of odour that no amount of scrubbing or spraying can touch.
Traditional cleaning products mask the smell with fragrance. When the fragrance fades, the odour returns. You're not solving the problem - you're renting 30 minutes of relief.
Meet the Device That Doesn't Mask Smells. It Destroys Them.
Smell Hound is the first residential odour elimination device powered by Synbio probiotic technology from Europe.
Instead of covering odours with fragrance, Smell Hound releases billions of beneficial probiotics into the air. These microscopic good bacteria land on every surface within 100 square metres - your carpets, furniture, curtains, and walls - and consume the organic matter that causes odours.
The smell doesn't come back. Because the source is gone.

Still Got Questions?
Is it safe around my pets and kids?
Yes — it's designed to be completely safe for everyday use around both.
The probiotic strains used are naturally occurring soil-based microorganisms that haven't been genetically modified. All ingredients are biodegradable, and their breakdown products are considered safe for both people and the environment.
These probiotics are classified as Biosafety Level 1 (BSL-1), meaning they are non-pathogenic and widely regarded as safe. They also meet cosmetic-grade standards, having successfully passed required dermatological testing.
In short: safe for your home, safe for your family, and safe for your pets.
Does it work on all types of odours?
Yes — Smell Hound is designed to tackle a wide range of everyday organic odours, including pet smells, cooking odours, mustiness, and more.
Rather than simply masking smells, it works at the source by breaking down odour-causing compounds. The result is a space that doesn't just smell better — it's genuinely fresh and clean.
What are Synbiotics?
Synbiotics are a combination of prebiotics and probiotics that work together to enhance effectiveness.
Smell Hound uses 100% natural synbiotic ingredients, carefully formulated and stabilised under lab-quality conditions. This pairing helps support and activate the beneficial bacteria, allowing them to break down odour-causing compounds more efficiently.
What are prebiotics and probiotics — and is there a difference?
Yes, there is a difference — and they work best together!
Probiotics are beneficial microorganisms that help break down odour-causing compounds at the source.
Prebiotics are specialised sugars that act as food for these good microorganisms. They support their growth and activity over time.
In Smell Hound's synbiotic formula, prebiotics provide a delayed, ongoing boost by feeding both the introduced probiotics and the naturally occurring "good" microbes already in your environment. This helps promote a healthier, more balanced microflora — leading to more effective and longer-lasting odour elimination.
Why use Smell Hound instead of normal cleaners or air fresheners?
Smell Hound takes a completely different approach to odour — instead of masking smells or killing everything with harsh chemicals, it works with nature to eliminate odours at the source.
Actually eliminates odours (not just covers them): Traditional air fresheners and candles simply mask smells, while many cleaners wipe out both good and bad bacteria. Smell Hound uses synbiotic technology to break down odour-causing compounds, leaving your space genuinely clean — not artificially scented.
Supports a healthier environment: Made with 100% natural, organic ingredients, Smell Hound contains no harsh chemicals, disinfectants, or synthetic fragrances. Instead of disrupting your environment, it helps maintain a balanced microbiome on surfaces, in the air, and even on your pet's fur and skin.
Deeper, microscopic clean: Smell Hound works on a microscopic level to remove proteins, organic dirt, and impurities that cause lingering smells. It also helps reduce allergens on pet hair while supporting skin health and the natural protective barrier.
Powered by pre- and probiotics: Probiotics (good bacteria) actively break down dirt and odour at the source, while prebiotics feed and sustain them over time — creating longer-lasting results compared to traditional cleaning methods.
More cost-effective over time: Buying sprays, candles, and cleaners adds up quickly — you're constantly replacing products that only provide short-term fixes. With Smell Hound, you invest in a long-term solution. You only need to top up with a refill bottle occasionally, which can save you money over time while delivering better results.
Better for your home, your pets, and the planet: No toxins, no cover-ups — just a smarter, more sustainable way to keep your space fresh.
How does Smell Hound eliminate odours at the source?
Smell Hound uses a smarter, biology-based approach to cleaning — powered by beneficial bacteria.
The device disperses a fine mist of Synbio® fluid using ultrasonic technology, spreading it evenly across your space (up to 50–100m²). This mist carries billions of good bacteria onto surfaces and into the air.
Once dispersed, these beneficial bacteria get to work by breaking down the organic compounds that cause bad smells. Instead of covering odours, they effectively "consume" the source — eliminating it completely.
It's the same principle that makes good bacteria essential in nature and in your body — just applied to your environment.
