The best aspect of iSpring’s product line is the range of products available. Consumers don’t have to explore across the internet to find exactly what they need. iSpring produces:
- Reverse-osmosis (RO) systems that filter up to 500 gallons per day
- Whole-house filtration
- Lime and calcium descaling systems
- Refrigerator water dispenser/ice maker filters
Here’s a breakdown, from smallest to largest water filter systems:
Small Filters
There are places in the home where filtered water is needed, but the homeowner doesn’t want to invest in a whole-house system to get it.
That’s where the engineers at iSpring stepped up and created water filters for those spots that could use clean water without the hassle of installing a complicated filtration system.
Refrigerator Water Dispenser/Ice Machine Filter – for great-tasting, contaminant-free water.
Showerhead Filter – get healthier hair and skin without the damaging compounds.
Faucet Head Filter – the easy way to get fresh, tasty water without the bother of a full system.
Countertop Filters
The idea of keeping matters simple continues forward with iSpring’s countertop filter products.
Nothing could be easier than a simple, snap-on connector that re-directs the tap water through a carbon block filter to eliminate 99% of over 1,000 contaminants. No plumber required!
CKC1 Model – single-stage water filter
CKC2 Model – two-stage water filter
CT10 Model – single-stage multi-filtration water filter
Under Sink High Flo Reverse Osmosis Filter
Under-sink filtration is useful in small homes and offices because they make it easy to get the cleanest water possible no matter what the source may be. Reverse osmosis water purification uses a combination of membranes, carbon, and other materials to clean out the more than 1,000 unwanted contaminants from tap water.
By pressurizing one side of a filtration element, water is forced through with the bad components left behind in the filtering materials. These tankless, reverse osmosis water filter systems are engineered for easy installation and filter replacement.
RO 100 5-stage filter system – lowest cost 5-stage system that can clean up to 100 GPD.
PH 100 6-stage filter system – an added Alkaline Remineralization filter to restore minerals.
RCB3P Light Commercial filter system – designed for salons, restaurants, and laboratories.
RO500 – 500 GPD capacity handles larger homes, small restaurants, and light commercial sites.
RCS5T – 5-stage, 500 GPD system for large families, small restaurants with storage tank.
Whole House Filtration Solutions
Nothing is better than the peace of mind from knowing all the water throughout the house is safe, clean, and ready for use no matter where it comes from. People, plants, and appliances all appreciate better taste, fewer contaminants, and less hard water build-up. Whole house water filtration systems may cost more money but they also solve more issues.
Big Blue water filters – 1-stage, 2-stage, and 3-stage water filters that eliminate 99% of contaminants.
Sediment and Scale filters – keep water sediment-free and protects pipes and appliances.
Well Water / City Water filters – for enhanced purification to remove bacteria and other undesirable ingredients.
UV filters – UV-light water treatment system for home-wide trustworthy water.
WF150K Central filter– eliminates contaminants and reduces lime and calcium build-up in homes, small businesses, and light commercial applications.

#1 – iSpring RCC7AK – 6-stage system
This is my number one choice because it covers all the bases that 90% of consumers need. This multi-layer system uses three Pre-filter cartridges to initially clean water and then the special reverse osmosis filters take over cleaning up to 75-gallons of drinking water per day. This choice also includes a final Alkalinization cartridge that returns needed minerals to make drinking water healthier and tastier.
| Feature | Benefit |
|---|---|
| 3 Pre-filters - PP sediment, Carbon KDF, Carbon Block | Remove larger particles and grains to enable secondary filters to do a better job. |
| Reverse Osmosis filter removes contaminants as small as .0001 microns | Nothing but water molecules can pass through the medium. |
| Granular Activated Carbon (GAC) filter | Guarantees water purity meets NSF standards. |
| Final Alkalinization filter | Replaces healthy minerals and sets proper alkaline balance for taste and smell. |
Pros:
- 6-stage layered filtration
- Low price
- See-through 1st-stage housing
- DIY installation
- Brushed Nickel and Brass Faucet included
Cons:
- Potential for leaks if not properly installed
- Pressurization issues with storage tank
#2 – iSpring RCC7 – 6-stage system

Honorable Mention – Other Products to Consider
Due to the variety of designs, placement options, and technologies available, there are some other products worth mentioning that many consumers should investigate further. Those products include:
#3 – RCC7P
This is a 5-stage filtration system design that eliminates the undesirable contaminants similar to the other RCC7 products except it has a pressure pump booster for those locations that suffer from low inbound water pressure. Consumers using well water, lake water, or other water sources with variable pressure find this model quite helpful.
#4 – RO100
The 100 Gallon-per-day capacity of this 5-stage reverse osmosis system is packaged in a sleek, user-friendly container. The filters are positioned horizontally and not vertically making them easier to replace than in traditional filtration systems. The whole product looks less like a plumbing experiment under the sink than most other products.
#5 – RO500
The tankless, 500 Gallon-per-day capacity makes this an ideal unit for large families, small restaurants, salons, and laboratories. The same ergonomic features as the RO100 with greatly increased capacity in a tankless design. Despite its large volume flow, this unit takes up less space than reverse osmosis systems with storage tanks.
These three products each have a unique set of features that are attractive to many consumers who want the convenience of water filtration and who need better quality water than what they get out of the tap.
For folks with adequate space under the sink for a water tank, the RCC7P and RO100 will do a great job. And if space isn’t available under the sink, the RO500 will exceed all expectations for size and convenience.
What to Consider Before Buying
If the water quality in your home or business is concerning, then there’s every reason to get a filtration system. Water tests produce some surprising results when it comes to identifying contaminants and other undesirable compounds.
Consumers in areas with “hard” water or water that leaves a lot of lime and calcium scale will want to look into a combination water filtration/softening system. Folks with concerns about salt content, bacterial infections, or other health issues consider purchasing a whole house filtration system.
Which Model is Best For Your Home’s Water Needs
Testing water will determine which filtering products will work best for you. I think each installation has unique conditions that should be considered before purchasing any product to clean water. For many consumers, product price is an important factor and iSpring has many cost-conscious options.
What Customers Say About the Products
Based on reviews submitted to Amazon and other websites that sell iSpring products, customer comments were mostly positive. There were some complaints about having difficulty with installing the products or with getting the system to function at first, but overall the responses were four or five-star ratings. One customer said his wife installed an under sink system in an hour and fifteen minutes – that’s impressive!
How Does iSpring Compare to Competitors
There are many players in the world of water purification with companies like Waterdrop, Aquasana, Pelican, and Home Master in the mix. All of the competitive products use filtering technologies that differ slightly but that meet national and international standards for cleanliness and purity. Cost-wise, I would say the iSpring products are priced competitively with the others but with some unique features other brands don’t offer.
One thing to note about iSpring products is that they only use iSpring filter cartridges and do not work with any other brand of cartridge. This is not the case with some of the competitive products.
Alternatives
There are two competitive alternatives that we recommend checking out before purchasing a filtration system:
Waterdrop manufactures its WD-G3-W 7-stage reverse osmosis system that is worth looking at due to its price and features. It is a tankless system similar to the RCC7 models. We think this is one of the top models on the market and would recommend it highly.
Aquasana OptimH2O system is another competitor with similar characteristics to the iSpring under sink filtration systems. This is a 3-stage system with a storage tank that costs much less than other systems while still providing the kind of water quality customers expect from more expensive products.
Conclusion
The iSpring approach to designing, engineering, and manufacturing water filtration products makes what can be a complicated and confusing decision much easier. From easy-to-install point-of-use products to whole-house and small business systems, there’s an iSpring product no matter what circumstance or water condition may exist. The iSpring product line is value-driven and feature-packed for consumers, commercial buyers, and everyone in-between.
