"Game changer for my apartment!"
"I live in a small studio apartment with two cats, and the litter box smell was becoming unbearable. Purrify completely eliminated the odor within 24 hours. I was skeptical about the price at first, but it lasts so much longer than other products I've tried. Worth every penny!"
- Sarah M., Montreal, QC (2 cats, small apartment)
How does a simple pouch eliminate such a stubborn smell? The answer fits in a single grain...
Why autoship
The smell comes back on a schedule. So does Purrify.
Activated carbon fills up like a sponge. One 50g bag holds about a month of odor for a one- or two-cat home. Run out, and your nose finds out before you do. Autoship lands a fresh 3-bag box every 3 months, so it never gets the chance.
1 bagabout a month of a home that smells like nothing
3 bagsone full season, delivered free, before you run out
$0.44a day on autoship, less than the air freshener you would give up otherwise
The science
One Gram. Half a Football Field of Surface Area.1
Inside every grain of activated carbon are millions of microscopic tunnels. When ammonia molecules float past, they get trapped permanently.2
The same stuff in your water filter. Meets NSF/ANSI 61 water-filter standards.
Ingredients: coconut shells. That is it. No fragrances, no chemicals, nothing to stress your cat's 200 million scent receptors.
Up to 92% less airborne ammonia. Independent bench-test result.
Your cat won't notice a thing. That's the point.
Works with any litter
Clay, clumping, crystal, natural. No switching drama.
Cat-safe and fragrance-free
Non-toxic, inert, and completely scent-free.
About a week per sprinkle
30 seconds of effort. A week of nothing.
Costs pennies a day

Why activated carbon works.
How Purrify compares to other odor products on the shelf.
High-surface carbon
Micropore capture sites
Activated carbon has a porous internal structure that gives odor molecules more places to adsorb.
At the source
Targets litter box ammonia
The granules mix into litter so odor molecules meet carbon before spreading through the room.
Weeks of use
Active odor control per bag
Baking soda saturates within days. Activated carbon keeps adsorbing for far longer.
Fragrance-free
No masking perfumes
Made to support your existing litter routine without adding heavy scent to the box.
Activated carbon's micropore network gives each granule a vast internal surface area where odor molecules are physically adsorbed.
The Same Stuff in Your Brita
Meets NSF/ANSI 61 standards. If it's good enough to make tap water drinkable, imagine what it does to ammonia.6
Ingredients: Coconut Shells. That's It.
No added fragrances or perfumes. Just pure, activated carbon from coconut shells.7
Science, Not Perfume
One gram has the surface area of a football field. Those microscopic tunnels trap odor molecules permanently. Gone. Not hiding.1,2
