Let customers speak for us
from 173 reviewsThe newest model of the Opti water filter is flawless. The water is delicious, the basin is large and functional, and it fits in a fridge that does not have tall spaces between shelves. Great customer service too. 10/10
I love Opti water filter. It gives me peace of mind knowing I will have clean, filtered water all the time. It also saves my back from lifting the heavy bottled water while saving the environment from plastic bottles.
We like it so far! Water tastes delicious and free of chlorine. It filters pretty fast.
I actually like to drink water now. Not true before using Opti Chill.
convenient process
great product !
Always a satisfying experience to drink my filtered Opti water.
Love my Opti
Super clean taste. Easy to change out filter when it needs to be replaced. This is our new source of drinking water.
Wevuse this in our studio and it removes the chlorine and the other things that are added to the water. The water filters through and it's so clean and fresh! Thank you for making such an amazing product. All of us at WellStrong
Really enjoy my optic water products. The water is amazingly good and refreshing.😊
Love my Opti. Have had it for about 2 years and the filters last a long while compared to others
We’ve filled up probably x10 so far and it still has a great taste. Loving the new addition to the household.
Good and clean water
This filter is the best thing I can get my hands on if I want good tasting water so fresh. I don’t know what I would do without it. No more bottle water Thanks you guys!!!
works great...thank you for great custumer service....
Everything went together easily and I have been drinking the water instead of bottled water. It’s Ph test was as good as the bottled water I used. So I’m glad to have a replacement for bottles.
