You've tried everything.
$900+ spent. Nothing worked.
That $350 HEPA purifier? Only captures particles. Your problem is gas molecules - ammonia from urine, VOCs from feces.
They're 1000x smaller than HEPA filters can catch. They pass straight through. That's like trying to stop mosquitos with a chain-link fence.
Carbon filters saturate within weeks. Baking soda makes ammonia worse. Scented litters create a "horrific combination of fresh linen and ammonia" that takes weeks to air out.

Here's what actually works:
Litter boxes produce 2 Types of Odor:
Feces VOCs (that "hot garbage" smell that fumigates your home)
Ammonia (that burning nose sensation)
Both are tiny gas molecules that need molecular-level elimination.
The OdourGuard Pro uses Bipolar Ion Technology™ - delivering two mechanisms:
Ionic Oxidation: Millions of negative ions chemically break down feces VOCs into harmless, odorless compounds (CO₂ + water vapor)
Ionic Precipitation: Pulls ammonia molecules out of your breathing zone via gravity, where they naturally dissipate
The result? Both odor sources eliminated before they spread through your home.
Yes. Safe for cats, humans, and children.
We know you're concerned. You've probably used products that:
The OdourGuard Pro:
No harsh chemicals - uses natural negative ions (same as after rainfall)
Silent operation (20dB) - won't scare cats or startle them
3rd Party Certified Ultra-Low Ozone (49x below CARB, the strictest air purifier standard in the US)
Safe for asthma & allergies
Vet approved and recommended
Used safely in veterinary clinics for years
Unlike plug-in air fresheners and chemical sprays, this doesn't add anything to your air - it just removes odor molecules that are already there.
The OdourGuard Pro is Independently Certified for Ozone Safety.
We sent the OdourGuard Pro to a third-party laboratory and published the full results. See our complete ozone testing report →
Your litter box doesn't have one smell problem. It has two.
You already know this without having named it.
There's the sharp, eye-watering sting that hits you in the doorway — that's ammonia, from urine. And there's the heavier, warmer smell that settles into fabric and hangs about — that's VOCs (volatile organic compounds) from faeces.
Different molecules. Different behaviour. They need different handling, which is why products that do one thing never quite fix it.
Now think about the air after a thunderstorm.
That clean, sharp quality isn't imagination. A storm floods the air with negative ions, and they change what's in it. This reproduces that effect continuously, in one room, at around 50 million ions per cm³.
Those ions do two jobs at once:
(volatile organic compounds) The ion collides with the molecule and triggers oxidation. What's left is carbon dioxide and water vapour — no smell, because there's no longer a smelly molecule. Destroyed, not covered up.
So why hasn't anyone done this before? They have — just not here. Ionic air treatment has run in water treatment plants and hospitals for decades. It's settled, unglamorous engineering. Nobody had built it at the right size and the right output for the one square metre of a home that actually needs it.
We know you're skeptical. You should be.
Here's what actual customers experienced:
Immediate: Ions begin eliminating odor molecules the second you power on. The process starts instantly.
Within a few hours: The "hot garbage" feces smell reduced by 80%. Ammonia levels dropped dramatically. You notice when you walk in the door.
By 24 hours: The burning nose sensation is gone. Air feels cleaner. Guests walking in won't smell anything.
Week 1: Your home stays clean 24/7 - even right after your cat uses the box. No more pre-cleaning panic before visitors.
Data from 3,421 customers:
Step 1: Plug the OdourGuard Pro into an outlet near your litter box. Wall-mounting above the box works best.
Step 2: Press the power button once. The indicator light will glow softly.
Step 3: That's it. Let it run 24/7 for continuous odor elimination.
Placement tips:
♾️ Maintenance: None. No filters to clean or replace. Ever.
The OdourGuard Pro works best when it's positioned near your litter box. The closer it is, the faster it eliminates odor before it spreads through your home.
Wall-mounting directly above your litter box is the ideal setup.
if your nearest outlet isn't within a few feet, just use a simple indoor extension cord to close the gap.
Try it risk-free. If you're not satisfied with the results, return it within 30 days for a full refund - no questions asked.
We're confident this will work for you. But we also know you've been burned before by products that promised and didn't deliver.
If you're not happy with how your home smells, you get your money back.
My sister got me this as a gift because she said my apartment smelled like cats and that she'd get a headache every time she visited. I didn't think it was a big deal, but after about a week I noticed I was sleeping better and waking up with more energy myself. I had no idea the litterbox air was affecting me that much!!
Watch how the OdourGuard Pro transformed their homes
Bipolar Ion Technology™ runs two mechanisms at once, because a litter box produces two completely different kinds of odour.
Generates 50 million negative ions a second that chemically break faeces VOCs apart into harmless, odourless compounds — at molecular level, not masked.
Charges the ammonia clusters floating in your air so they become heavy. Gravity pulls them down and out of your breathing zone, where they naturally disperse.
Three steps, thirty seconds, then you never think about it again.
Position it near the litter box — wall-mounted or in a socket. Takes 30 seconds.
Press the power button once. A soft indicator light confirms it's running.
Continuous odour elimination, 24/7. No maintenance, no filters, ever.
You deserve to feel your best at home.
Litter trays release ammonia and faeces VOCs around the clock. The OdourGuard Pro uses Dual-Action Ion Technology™ to eliminate both at the molecular level — protecting your air, not just masking it.
Ammonia is a known respiratory irritant. Clear it out of the room and the heaviness that comes with breathing it all evening goes with it.
It isn't just you. Everyone in your home is breathing the same air — partners, children, guests, and the cats themselves. One socket covers all of them, 24/7.
Your nose adapted to the ammonia. Your lungs didn't. No more inhaling something your body was never meant to tolerate.
Independent lab testing
Any device that generates negative ions produces a trace of ozone — that's physics, and we won't pretend otherwise. So we had ours independently tested and published the results in full.
0.002 mg/m³
Measured ozone output under standardised test conditions.
49× below
The CARB limit — the strictest air purifier standard in the US.
At 1 watt, the device is physically incapable of producing meaningful ozone. The report shows the methodology, not just the number.
Experience the transformation from the moment you plug it in.
50M+ ions per second begin eliminating ammonia and VOC molecules the moment you power on.
Ammonia levels drop sharply. Leave the house for 30 minutes and walk back in — you might notice the difference for the first time in months.
That heaviness from breathing ammonia all evening lifts. The air in your home feels lighter and cleaner.
Your home simply smells clean, around the clock — even right after the tray has been used. This is what it was supposed to feel like.
HEPA filters can't trap gas molecules a thousand times too small. Litters can't touch ammonia that's already airborne. Deodorisers mask it, or make it worse.

From "I had no idea my home smelled" to "guests can't tell I have cats" — see how the OdourGuard Pro changed things at home.
I used to come home from the gym feeling great and within an hour I'd be completely wiped out on the sofa. Made no sense — I'm in good shape, I eat clean, I sleep well. My mum visited and said my place smelled like a litter tray the second she walked in. I had no idea. Got this and now I actually have energy at home. Turns out I was breathing ammonia every night and didn't know it.
My eyes would water and my throat would get scratchy every evening. I went through three different air purifiers trying to fix it. Spent over £800 in total. None of them touched the litter tray smell, because apparently they can't filter gas. This little £31 device did what £800 of purifiers couldn't.
I spent two years assuming I'd developed a cat allergy. Sneezing, itchy eyes, every single evening. A colleague with cats told me about ammonia building up around litter trays and suggested this. Six weeks in and the evenings are completely different. It wasn't the cats at all.

I was constantly paranoid, obsessed with asking everyone "do you smell cat?" My boyfriend, my friends, random guests - always seeking validation because I couldn't trust my own nose. The anxiety was exhausting. This gave me peace of mind. I finally know my apartment doesn't smell. The paranoia is gone.
The ammonia was so strong it literally burned my nose and throat every time I walked into my bedroom. I'd wake up with headaches. My doctor said it was respiratory irritation from the fumes. Within just a day of using this, the burning sensation stopped completely. I can breathe normally again.
I work from home 5 days a week with my litter box 10 feet from my desk. The poop smell was giving me headaches by afternoon. I'd open windows year-round just to breathe. This eliminated the problem completely. I can finally work without feeling sick. Air quality feels totally different.
I wish I'd bought this before getting my cat. I researched obsessively before adopting because I was terrified about smell in my studio apartment. Tried premium litters, daily scooping, everything. Still smelled. Found this and it changed everything. If you're considering getting a cat but worried about odor - just buy this from day 1.
I have 5 cats in a 1200 sq ft house. FIVE. Everyone said it was impossible to keep it smell-free. I'd spent over $900 on different solutions - nothing worked. Bought 3 of these units (one per main room). My sister visited last week and said "I can't believe you have 5 cats, I smell nothing." First time in 3 years someone said that.
My elderly cat has kidney disease and her "business" is extremely potent. The smell was unbearable no matter how often I scooped. I was seriously considering putting her down because the smell was making us both sick. This saved her life. The smell is manageable now.
Everything people ask before they buy.
A litter tray gives off two different kinds of odour molecule, so the device runs two mechanisms at once. Plug it in and it starts producing 50 million+ negative ions per cubic centimetre.
Faeces smell (VOCs). Ionic oxidation breaks those compounds apart into carbon dioxide and water vapour. There's no smell left because there's no longer a smelly molecule — nothing is being masked or trapped.
Urine smell (ammonia). Ionic precipitation charges the ammonia clusters floating in your air until they're heavy enough for gravity to pull them out of the air you're breathing.
HEPA purifiers only capture particles, which is why yours never touched this. These are gas molecules roughly a thousand times smaller than anything a physical filter can hold.
Yes — and we'd expect you to check. Safe for cats, humans and children.
Cats with respiratory sensitivities tend to do better with it running, since ammonia irritates their airways as much as yours. See the full test results →
A trace, yes. Any device generating negative ions produces some as a by-product — that's basic physics, and we're not going to pretend otherwise.
So we had it measured independently. The result was 0.002 mg/m³, which is 49 times below the emission limit set by CARB, the strictest air purifier standard in the US. At 1 watt, the device is physically incapable of producing meaningful amounts.
It goes to work the second you switch it on, and most people notice a clear change within a few hours.
Give it a full day before you judge it, though. The strongest test is walking back in from outside — you stop registering your own home's smell within minutes of being in it, so coming in from the cold is when you'll actually notice.
After that it just runs, dealing with odour as it appears, including right after the tray has been used.
Never. There are no filters and no ongoing costs.
Ionic generation isn't physical filtration, so there's nothing to clog, saturate or swap out. Performance on day 1,000 is performance on day one.
A HEPA purifier costs £25–40 a filter every few weeks. This costs nothing after you've bought it. Plug it in once and forget about it.
One per litter area covers most homes.
If your trays are in separate rooms, or the smell is bad enough that you've been avoiding a room, one per room works better. Households with three or more cats often run two or three.
Position each one near where the tray actually sits, not in the middle of the room — you want it dealing with odour where it's strongest, before it spreads.
Yes — a 400 sq ft studio or a large house. Floor area matters far less than placement.
Put it near the tray, where ammonia and VOCs are most concentrated. Deal with them there and they never spread through the rest of the house.
Any nearby socket works, or wall-mount it directly above the tray for the best position. No installation, no tools.
You've spent money on things that didn't work before, so being sceptical is reasonable.
30 days, full refund, no questions asked. If your home doesn't smell fresh, just tell us and we'll refund you — no need to post anything back.
This isn't a miracle product — it's settled ionic technology aimed properly at litter tray chemistry. But if it doesn't fix your particular situation, you're not stuck with it.
HEPA captures particles down to about 0.3 microns. Ammonia and VOC gas molecules are around 0.0003 microns — roughly a thousand times smaller. They pass straight through the filter.
It isn't a cheap-versus-expensive thing. Physical filtration is simply the wrong tool for gas, no matter what you spend. This works at molecular level instead.
