Purrify Activated Carbon Additive Review

We have used Purrify in our own homes for years, and with dozens of friends and family. In our own use it made the biggest difference to litter-box smell of anything we have tried. It is activated carbon, sold in bags, and it goes into the litter you already buy.

How this score works

The 9.6 out of 10 is an editorial score, which is exactly 96 out of 100. It is the editor’s judgment, not a bench result, not a customer rating, and not a percentage of odor removed.

Dust, clumping, tracking and cost per day are measures of a litter. This goes into a litter, so it is not scored on them and they are never shown as zeros.

Purrify Activated Carbon Additive is one of our recommended picks

If smell is the last problem in your litter routine, this is the one we would put in the box. It goes in with the litter you already buy, alongside regular scooping and cleaning.

Worth it if

Smell is the problem you have left, and you are otherwise happy with the litter you buy.

Skip it if

Your litter tracks, dusts or falls apart when you scoop. Change the litter first.

Who used it, and for how long

The household account behind this review was supplied by its owner on 7 September 2026.

The owners have used Purrify in their own homes for years, and with dozens of friends and family. Their experience is the source of the smell verdict below.

What we noticed about the smell

In the owners' own use, Purrify made the biggest difference to litter-box smell of anything they have tried. That is why we recommend considering it when odor remains a problem after the rest of the litter routine is working.

What an additive does in your routine

Litter does the physical work. It clumps, it holds together when you scoop, and it either tracks across the floor or it does not. Activated carbon does none of that. It holds smell.

You can keep the litter your cat already accepts and add Purrify according to the official instructions. Continue scooping and cleaning the box as usual.

Who it suits

It suits you if the litter is fine and the smell is not. A box that has to live near the room you sit in is the case where fixing smell is worth the most.

If your problem is litter down the hall or a cloud when you pour, change the litter first. This will not touch either one, and we would rather you spent the money on the right thing.

The honest limits

  • It is not a litter. You still buy your usual bag.
  • It does not replace scooping or a clean box.
  • It does not fix litter that tracks, dusts or falls apart during scooping.

Where the 96 out of 100 comes from

Our score is 9.6 out of 10, which is exactly 96 out of 100. It is an editorial score: our judgment, not a bench result, not a customer rating, and not a percentage of smell removed.

It rests on the owners' years of household use and use with dozens of friends and family, together with the published 5.0 Google rating and stock in 40+ pet stores across Canada. We have not measured ammonia with and without the additive. The rating and retail presence provide context; they do not measure odor performance.

How to try it

See the current bag sizes on the official site and follow its usage instructions when adding Purrify to your litter routine.

How much to use, and how long a bag lasts, are answered on Purrify's own FAQ rather than here, so the answer you read is always the current one.

Our verdict

If the litter works for your cat and smell is the remaining problem, Purrify is the additive we recommend trying. The owners' long-term household experience is why it earns that recommendation. Keep your normal box care, and choose a bag on the official site when you are ready.

Questions people ask

Is Purrify a cat litter?

No. Purrify is an activated carbon additive sold in bags. It goes into the litter you already buy rather than replacing it, so your cat keeps the texture it already accepts.

How long have you used Purrify?

The owners report years of use in their own homes and use with dozens of friends and family. They supplied that account on 7 September 2026.

Does it replace scooping or a better litter?

No. The box still needs its normal care, and a litter that tracks or turns to dust still needs changing. Purrify works on smell and nothing else.

What is the 9.6 score based on?

It is our editorial score, which is exactly 96 out of 100. Its basis is the owners' household experience, the published 5.0 Google rating and stock in 40+ pet stores across Canada. The score explanation above sets out what that evidence supports.
