OPTI Drop - Alkaline Replacement Filter - 200 Gallons

Honestly best tasting filtered water I’ve had. I’ve tried all the other brands and OPTI is superior. You can tell this filter is really doing its job. Extremely high quality and it just feels like it’s doing a better job of ridding impurities in the water.Great customer service if you need it as well. Good job OPTI.

The filters work as intended. I just wish the user (my family member) remembered to buy and change out the filter every few months.

It’s not the same like couple years ago including the external cover. Cost is raised but quality is reduced. Water seems to be contaminated with green algae faster than 6 months even I use filtered water and flushed this filter for more than 100 puffs with pure filtered water. Look like quality is degraded. I have not checked the alkaline density yet. Please don’t rationalize with tariffs since I bought prior this period.

I had the older version of this filter for the water filter unit and upon seeing the updated replacement , it was a no brainer to pick. I replaced the old filter design for the new one and it was simple and easy to install.

It is a great product. I have the Opti drop for 3 years. And I love it. Will keep buying the filters for long time..

Super easy to use.. water tastes good and i find myself more inclined to drink water. I bought separate test strips to confirm alkalinity and it confirmed what they claim.

Replacing the filter to my amazing Opti Drop is so easy and inexpensive.

The new filter does make it filter a lot quicker, which I don't know is a good thing. I had to replace my filter after only 2 months because the filter isn't filtering as well. In the past, I was able to have my filter for about 3 months. They should probably lower their price of this filter, or readvise their claims of "about 200 gallons" because I have not found this to be the case as my filter didn't come close to 200 gallons.
