Do The Pros Of Costco's Reverse Osmosis Water Filtration System Outweigh The Cons?

Buying a water softener at a bargain price can be tempting, but it's worthwhile to proceed with caution. Always check the reviews first to make sure the filter's actual function matches what it claims — water quality is something you don't want to compromise.

At Costco, you can find a Brondell Circle Reverse Osmosis Water Filtration System for the fairly low online price of $259.99. If you have an Executive Membership, you might prefer to make your larger purchases there to take advantage of their 2% Reward program. But, does their reputation for quality kitchen appliances hold up with this filtration system? 

While reviews vary, the Brondell Circle filtration system has overall positive reviews. Currently, it sits at a rating of 4.2 out of 5 stars on the chain's website. Its compact size and easy installation steps lead to a generally good first impression among purchasers. After you've bought it and set it up under your sink, here's what might you notice once a few months have passed.

Most consumers are impressed by the taste — or lack thereof — of water from the Brondell Circle reverse osmosis system. One reviewer notes that it "makes a huge difference with cooking ... the Brondell does a great job and is on par with the water you buy in a store." If you live in an area with hard tap water and can't stand the taste, the Brondell Circle can be a more sustainable option to bottled water.

This water softener is also known for its reliable flow rate. Compared to a previous filtration system one reviewer had purchased, they appreciated how the Brondell Circle "does not decrease to a drip over time." That being said, the water pressure leaves something to be desired. That same reviewer noticed that they "would like a little more volume in the flow," and other reviewers tend to agree on this point. While the flow might be steady, it can take more time than is reasonable to fill up a pitcher.

Additionally, while Brondell suggests replacing filters every six months, some reviewers complain that they need more frequent replacement with regular use. Every three to four months tends to be the average mentioned in reviews. If you're drawn to the Brondell Circle, the frequent filter replacement could outweigh its initially low price.
