Our Review/Thoughts
Will definitely buy them again!!! Much, much cheaper than buying them a few at a time, and they work perfectly in my Drinkwell fountain
The filters do the job for which they were intended (this is a reorder so we know the brand)
This took awhile to arrive but we ordered for next year so it didn't matter
I purchased the PetSafe Drinkwell Fountain Cleaning kit along with the filters and highly suggest that as well
I recommend you replace them as directed and flush them properly
Overall a good filter at a good price and I am very pleased with my purchase
