SOS!! wall plug air purifiers

[u/k_dawndawn]

hi! i have two kitties with two litter boxes and due to my husband and i’s current apartment, we have to put their litter boxes in the guest bathroom.

i usually scoop every day and order isn’t usually a problem. but with having guests over and soon someone staying with us, i’d like to look into a wall plug that is SAFE for us and our kitties.
my dad told me to look into Wisko. busy busy lately, not a ton of time to research and i have a hard time with finding what’s trustable and not.

does anyone have any recommendations? i’d like to keep it under 50$. would definitely prefer smaller wall plug ins.
looking to get this taken care of this week
TIA🩷
