You love your fur babies, not the smell they leave behind. The Mewly Pro uses Bipolar Ion Technology™ to reduce and eliminate litter box odors at the molecular level instead of masking them.

Most homes notice the sharp ammonia smell drop within a few hours, with fresher air by the end of day one (see the timeline above). Try it at home with our 30-Day Try-at-Home Guarantee.
Yes. Mewly Pro is scent-free, silent and uses no essential oils or chemical sprays, so there's nothing for your cat to breathe in or avoid. Give your cat a fresh corner they'll actually love.
No. It's silent (no fan, no motor) and has no scent of its own, just a soft indicator light, so most cats ignore it from day one. Your cat keeps their routine; you just lose the smell.
Use one Mewly Pro per litter box for the best results. Most multi-cat homes choose the 2 or 3-pack, and save up to 40% doing it.
No. Mewly Pro plugs into any standard wall outlet and runs 24/7 on very little power. Plug it in once and forget about it: nothing to charge, nothing to replace.
Yes: Mewly Pro handles the smell between scoops, not the scooping itself. Keep your usual routine and enjoy a home that smells fresh in between.
No filters, no refills, ever. You pay once and it keeps working: no subscriptions, no hidden costs.
Plug it into the outlet closest to your litter box; the closer it is, the faster it stops odors before they spread. If your outlet is a few feet away, a simple indoor extension cord closes the gap, then it does the work around the clock.

I've tried everything: enzyme cleaners, ten different litters, $400 air purifiers. Nothing worked. I can't believe I didn't buy this earlier. My litter box area has been fresh ever since I turned this on. All my friends come over and don't know I have cats until they see them.
Watch how the Mewly Pro transformed their homes
Every cat owner knows these moments. Mewly Pro was made for all of them.
You put the key in the lock, open the door, and take that first breath. And there it is. Before you’ve even put your bag down, you know the litter box needs attention again.
You scooped this morning. It doesn’t matter. The smell got there first.
A friend texts: “I’m outside!” Your stomach drops. You’re opening windows, grabbing the air freshener, and apologizing before they’ve even taken their shoes off.
“Sorry, it’s the cat.” You’ve said it so many times it comes out automatically.
Dinner’s on the table. Everyone sits down. And right on cue, your cat heads to the litter box.
Thirty seconds later, the whole room knows. Nobody says anything, but nobody’s hungry anymore either.
They walk in after work, pause in the doorway and say it again: “It smells like cat in here.”
You love your cat. They love your cat. But that one sentence has turned into the same argument every week.
No spare room. No laundry room. The litter box lives 10 feet from your bed, and at 3 a.m. you can smell it from your pillow.
You can’t move the box. You can’t open a window in January. You just live with it.
Here’s the part nobody tells you: after a few weeks, your brain stops noticing the smell. It’s called nose blindness.
You don’t smell it. Your guests do, in the first five seconds.
One device. Every one of these moments, gone.
Bipolar Ion Technology™ uses dual mechanisms to reduce and eliminate both odor types at the molecular level
Generates 50 million negative ions per second that chemically break down feces VOCs (volatile organic compounds) into harmless, odorless compounds at the molecular level.
Reduces Feces OdorWorks While You Sleep
Charges ammonia-particle clusters in your air, making them heavy. Gravity pulls them down out of your breathing zone where they naturally dissipate.
No More Burning NoseBreathe Clean Air 24/7
Right after your cat uses the box, odor spikes. At dinnertime. At 3 a.m. Before you can even grab the scooper, the whole room knows. That's the moment sprays, candles and purifiers miss.
Mewly Pro runs 24/7 from a wall outlet, so there's nothing to turn on when your cat goes.
Millions of negative ions are working around the litter box before your cat even steps in.
Fresh odor gets broken down near the source, so it doesn't drift into the rest of your home.
See how you can stop litter box odors in just 3 simple steps.
Say Goodbye to Embarrassment, Nose Blindness, and Failed Solutions
Stop apologizing when guests arrive. Stop worrying if they notice. Your home will smell clean. Period.
No more wondering "can they smell it?" You'll know your home is odor-free because visitors will tell you they can't even tell you have cats.
End the complaints from partners, roommates, and landlords. Finally, a solution that makes everyone happy.
No more burning nose sensation from ammonia. No more respiratory irritation. Just clean air you can actually breathe.
After a few weeks, your brain tunes out the smells it lives with every day. It's called nose blindness, and it's why cat owners are always the last to know.
You walk in and the litter box hits you. You scoop, you spray, you light a candle.
The smell is still there. You just can't detect it anymore, so you assume your home is fine.
They smell it the moment the door opens. Most of them will never tell you.
Mewly Pro fixes the smell you stopped noticing, before anyone else notices it for you.
Protect My Home
Board-certified veterinarian explains why this works
I've been recommending the Mewly Pro to my clients for 2 years now. The science is sound: negative ions genuinely break down VOC molecules and precipitate ammonia. Unlike chemical sprays or ozone generators, this is safe for cats and humans. It's the first solution I've seen that actually addresses the molecular problem instead of just masking it.

Experience the transformation from the moment you plug it in.
50M+ ions per second begin eliminating odor molecules on contact the moment you power on.
That sharp cat pee ammonia smell drops dramatically, and it's the first thing to go. Even the heavier "hot garbage" feces smell starts to fade. You'll notice when you walk in the door.
That burning nose sensation? Gone. Air feels cleaner. Guests walking in notice the difference.
Your home stays fresher 24/7, even right after your cat uses the box. No more pre-cleaning panic before visitors.
Sprays, powders and candles only cover the smell. HEPA filters can't capture gas molecules 1000x too small. Self-cleaning boxes cost hundreds and still leave the smell in the air. Mewly Pro reduces and eliminates both odor types at the source.

See how Mewly Pro took these homes from desperate to odor-free.
I've been embarrassed about my house smell for 3 years. Constantly apologizing to guests, lighting candles, opening windows. The Mewly Pro removed the smell. I wasted so much money on solutions that didn't work. This should have been my first purchase.
I live in a 600 sq ft apartment with 2 cats. The smell was so bad my landlord threatened eviction. I tried EVERYTHING: enzyme cleaners, $400 air purifiers, raw diet, you name it. This is the only thing that actually worked. The smell is GONE.
My roommate complained about the cat smell constantly. It was causing real tension. I bought this as a last resort before rehoming my cat. It worked. She doesn't complain anymore. She even said 'I don't smell anything now.' Saved my relationship with my cat and my roommate.

Constantly paranoid, obsessed with everyone "do you smell cat?" My dad, my friends, random guests. I was seeking validation because I couldn't trust my own nose. The anxiety was exhausting. This gave me peace of mind. I can 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. Everyone said it was impossible to make it smell-free. I'd spent over $900 on solutions and nothing worked. Bought these units (one per main room). My mom visited last week and said "I can't believe you have 5 cats, I smell nothing." First time in 3 years someone said that.
