## Description

desertcart.com: iSpring FT15 NSF Certified 5th Stage Inline Post Carbon Water Filter, Replacement Cartridge with 1/4" Quick Connect for Refrigerator, Ice Maker, RO Reverse Osmosis Water Filtration System : Tools & Home Improvement

Review: System lasts: Clean water, great taste and feel. Renter friendly price. Nature & we both benefit. - Super system at this price! We've bought it years ago. Of course, the filters fit. We installed the iSpring reverse osmosis set a few years back. It is well worth it's money by now. Water from regular interval filters tastes good to me, and I am sensitive when it comes to water's taste. Can't drink odd or off tastes without cringe. I like arrowhead though not in ecstasy about it, not ok from plastic bottles stored in hot weather except in emergencies. I like some mountain streams and some wood springs, am ok with occasional, light carbonation - though it won't improve the taste, just change and mask it. We also used different $15-30 test strips on occasion throughout the house and this water's our clean baseline. I hate chlorine taste and feel and do not want more iron or lead or PFAS than necessary, either. There's only so much antioxidants can do for us. So, despite the terrible fact that this system wastes 2x the amount of water you get from it (wish we could rig it so the excess watered our garden or plant) - this is totally worth it to me. I try to meditate when filling a bottle to put in the fridge for the day, it takes about 20 seconds. It's not so bad with just a glass, but it also isn't for the super easily annoyed. Our storage canister, which is slowly refilled with pre-filtered water after you tab out some, is great for two or three people to drink and cook. If you need a lot of water at a time, you might require a larger system. Think of the time saved hauling and trashing bottles, that gives ample patience and glee to the adults at least. Installation is a bit tedious but straightforward enough. And here's a secret superpower: iSpring's customer service is actually super friendly and helpful! After some years the system started dripping (to refill the reservoir) and just didn't stop unless we turned off water. Called CS and they helped us troubleshoot successfully. Yey! If you have no savy at all, get someone to install this for you and set a reminder to replace filter cartridges on schedule. Especially renters profit from the compact and relatively easy system, it takes some space but leaves enough of room under our double sink for two small trash bins and detergents. The shower's got a cheaper filter (which won't waste) and I would NOT drink that water. It's just barely ok on the skin. This water quality's actually impressive given the price of this system is in the low hundreds. Even disregarding eventual medical bills you prevent, you'll save that back financially by just stopping to shop bottled water. We get solid bottles and just refill, wash, refill for up to a year of reusable, high quality plastics or years on end with stainless. Health, economy, even ecology benefit (considering this set lasts us years now and we used to buy plastic bottles, made with a lot of damage to water) - We're very happy.
Review: Great quality of water - It was easy for my maintenance team to install. Everything was included My water continues to taste fantastic. I had difficulty registering my warranty.

### ⭐⭐⭐⭐⭐ Best RO system, best company service!
*by K***H on January 19, 2026*

iSpring I purchased an iSpring RCB3P 300 GPD Commercial Grade Reverse Osmosis Water Filter System w/ Booster Pump and Oversized Pre RO Filters from Amazon and for some unknown reason Amazon does not have a record of this purchase so I could not leave comments on the actual system, and used the replacement filter I purchased after the fact so I could leave this comment for iSpring. Here is what I need to say about the iSpring RCB3P 300 GPD system: It has been a water filtering workhorse producing clean water above their stated quantities. It took my hard water of 283 ppm down to 8 ppm, and the waters heavy iron and calcium levels made it undrinkable, and now it tastes amazing. Also, during the time I have used the system I had a few small issues and contacted Sean at iSpring and I received the best and amazing customer service I have ever witnessed! Seriously, they support their products well above and beyond any company I have ever done business with. I am completely satisfied with iSpring’s products and service, I would give 100 stars if allowed. Thanks Sean!!
