iSpring RCC7 WQA Reverse Osmosis System 5-Stage Under Sink Water Filter Review

iSpring RCC7 Reverse Osmosis System Review

To protect your family from harmful contaminants in your drinking water, you need a filter. The most efficient type of water filter is a reverse osmosis system, which pulls water through a semipermeable membrane to remove fluoride, lead, sulfates, and other harmful substances.

You can either drink bottled alkaline water or add a reverse osmosis system to your house.

The popular iSpring RCC7 reverse osmosis water filter has garnered thousands of positive reviews across the web, but is the product as great as it seems?

Overall, we were impressed with both the high-quality and consistency of the iSpring RCC7. It has some amazing features, including:

  • Up to 99% Contamination Removal: The best thing about any reverse osmosis water filter is its ability to remove contaminants from water so that you can safely use it for drinking, cooking, and making coffee. The iSpring is capable of removing over 1,000 different contaminants through a semi-permeable membrane, making it more effect than carbon filters.

Product Cons

  • Leaking: While rare, some customers have reported small leaks. Most of these are easily patchable with sealing tape. 

Customer Reviews

To conduct our review, we looked at what iSpring users had to say about the quality of the product.

The product’s Amazon reviews are overwhelmingly positive, with 95% of the nearly 3,000 reviews being 4 or 5 stars. Customer’s favorite things about the iSpring were how it improved the flavor of their water, was easy to set up, and gave them peace of mind.

The most common problems reviewers expressed in negative reviews were issues with leaks and problems with installation in smaller cabinet spaces. While these problems appear to be rare, it’s still something to consider when choosing a reverse osmosis water filter.

The iSpring RCC7 is produced by iSpring Water Systems, a Georgia-based company with more than 10 years of experience manufacturing reverse osmosis systems. While the filters are not manufactured in the USA, customers who have had trouble with the company’s products have found iSpring’s customer service to be incredibly helpful and reliable.           `
