Gonzo’s air purifier bags were the worst we tested. While it does come with a handful of bags, you’ll need to buy refills for about $10 per pack of two. The bags are also very small, so it takes quite a few to cover a large area.
While this purifier did reduce the odor in the room, it wasn’t as much better than the other purifiers we tested. It’s also the most expensive option we tried. Even with those drawbacks, it did seem to work more effectively than some other purifiers we tested that cost less.
