Opti 200 Gallon Alkaline Filter Replacement (4-Pack)

Defective filter change water color to green !!!

The product came in a small size. It takes a long time to return, so just use it. Because of its small size, it takes a long time to filter.

I have bought the set of three filters three times now I�ve been using the filtration device for a few years. The latest set of filters allows the water to run through much faster than in the past. This tells me there�s less charcoal in the unit than they used to put in. Of course, I don�t know this for sure. I have removed the filter and shaken it and re-rinsed it only to find that the water actually runs through even faster now. I just don�t feel as though it�s filtering as well when the water is passing through so quickly.

Dirction said needed syringe included but it wasnt. Other than that works as stated

This filter provides a PH of 5, not 9 or even 7. Of course, a PH of 9 is too high but at least a 6! Also, the water pressure for the filter flows out too fast, not like the slow drip as stated. However, it does remove chlorine like they said, will have to test the heavy metals and other contaminates to see if that holds true. Now I did reached out to the company and they will send a replacement filter. I will have to see how the replacement filter works before updating my stars..

Filter works fine it just doesn�t fit properly in the container. I have to put the lid on backwards for it to stay on

Leaves a couple cm of water left over in the tank

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.

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.

For the price and after following instructions my last 2 filters have not worked and have released a lot of the material into the water.

It is really expensive. More that it should be.

These filters are a good value for the money. The fact that you can get four months of filtration from this one filter is awesome. I will be buying more.

Opti drop container & filter really work well at filtering water. Also I feel better not buying water in big plastic jugs. Less plastic in our oceans & fresh clean water to boot.

Good

Easy to install.....:Filters Well! Love the water! Test results are Good!

Fits and does it�s job

easy to install

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

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.

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.

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.

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..

Does what is suppose to do.

Good Service and Price.

Great price!

Good products
