90 owner reviews, fewer than most models here
The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other water filtration: replacement filters, under-sink and reverse osmosis systems, filter pitchers, water dispensers, coolers, faucet filters and softeners we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
The iSpring RCC1P is an under-sink reverse osmosis system rated at 100 gallons per day. It measures 19 x 8 x 14.5 inches and weighs 33.5 pounds, making it one of the heavier options in the under-sink category. The material is listed as 'RE,' which likely refers to the filter housing material but is not fully specified in available data. At $310.49, it sits between budget RO options and the higher-priced RCC1UP.
With just 90 reviews, the sample size is modest. The 4.7-star average is among the higher scores in the iSpring lineup, but fewer than 100 reviews limits how much weight that figure can carry. Buyers who have used other iSpring systems and trust the brand will find this a more appealing option than someone researching RO systems for the first time.
No third-party certification is confirmed in the product data. As with other iSpring models, checking current certification documentation directly with iSpring before purchase is advisable.
Pros
- 100 GPD output, higher daily production than standard 75-GPD systems
- 4.7-star average across current reviews
- Under-sink design frees up counter space
- Lower priced than the brass-construction RCC1UP at comparable output
Cons
- Only 90 reviews, limiting confidence in the rating
- 33.5 pounds requires sturdy mounting and adequate cabinet support
- Material listing is ambiguous in available data
- No confirmed third-party certification

Performance notes
The RCC1P uses reverse osmosis as its purification method. RO membranes are designed to reduce dissolved solids, chlorine taste, certain heavy metals, fluoride, and nitrates. The 100-GPD rating indicates daily production capacity under standard conditions, not instantaneous delivery flow. A pressurized storage tank is typically required alongside the system for on-demand flow. The unit footprint of 19 x 8 x 14.5 inches is on the larger side and needs a reasonably deep cabinet.
What buyers say
The 4.7-star average is one of the stronger ratings in the iSpring line, but only 90 reviewers have weighed in. This suggests early buyers are satisfied, but the data pool is not large enough to confirm long-term reliability trends. Buyers already familiar with iSpring's service and warranty support may be less concerned by the limited review count.

Both are rated at 100 gallons per day, but the RCC1UP uses brass construction and is priced higher at $419.99. The RCC1P comes in at $310.49. The brass fittings on the RCC1UP may offer longer-term durability, while the RCC1P offers similar output at a lower cost. Review counts differ significantly, with the RCC1UP having about 106 reviews versus 90 for the RCC1P.
Does the RCC1P come with a storage tank and faucet?
The product data does not confirm tank or faucet inclusion. Traditional under-sink RO systems typically require a pressurized tank for on-demand delivery. Verify the current kit contents on the listing or contact iSpring before purchase to confirm what components are included.
