Aquasana AQ-RO3-RM Replacement Remineralizer for OptimH20 Reverse Osmosis Water Filter - Not Compatible with SmartFlow Systems

The Remineralizer really makes a difference to our Reverse Osmosis. There is nothing like a glass of good-tasting water, and that is what these provide. We have them on 6 6-month subscription. I swap out the old one when I do my filter replacement. They are really easy to install because of the push-to-connect fittings, and there is no problem with leaking.

This adds more minerals back in than some other brands. I even have a different brand RO filtration system and converted it to fit this for the better quality. Uses 3/8 tubing so you might need to get a 1/4 to 3/8 conversion kit if you want to use it.

Easy to install and gives my water more flavor over straight RO water.

Good

I installed this cartridge with another brand RO system with great results. The water has a better taste and it results in more flavor in coffee. It has 3/8" sharkbite fittings installed so I bought adapters at Home Depot to connect it to the 1/4" tubing my system uses, it doesn't seem to have affected system pressure or flow at all. Make sure to run a couple quarts through before drinking, or you'll have a few glasses of very strange tasting water.

Did you know which over-the-sink water filter model was preferred by non-profits handing out filters to residents in Flint, Michigan? That's right, Aquasana. That's because their established quality and unmatched customer service is famous in the consumer water treatment world. We've been satisfied customers of Aquasana for over 10 years and have used several of their models over the years and across different houses we've lived in. We just updated our under the sink dual-filter drinking system with a reservoir tank to help boost the pressure coming out of the filtered water spout. Added this mineral filter to the chain, after the reservoir to add in some of the flavor lost by the filter and the water softener. The first day was a bit overboard but ever since it's been beautiful. Like drinking the well water from a mountain cabin in Switzerland

Quality product. And tastes good. No leakage

This filter is small!! I realize there are plenty of good reviews out there. Also, it's made in China. Was going to send it back but decided to connect it and see how it goes. Would not have ordered this item had I realized it was made in China and about a third the size of other remineralizers.

These are authentic and are a great replacement.

Look like legit Brand Name Aquasana filter. After 1 month of use there’s no problems.

Good product

Works as expected
