desertcart.com: iSpring FA15 Alkaline Inline Water Filter Cartridge, 10” x 2” with 1/4” Quick Connect, NSF Certified, Add-on for RO Systems, Balances pH & Restores Minerals, 3-Layer Replacement Filter : 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: works incredibly well, good value, excellent customer service, TASTE UNBEATABLE - I purchased this system in February 2018, I wanted to wait a while to see how it performed before writing a review. I have a background in water quality and am a bit of a water snob so I had very high expectations for quality and the water it produced. Installation was great, they include everything you need to install it on existing equipment. It attached to the cold water angle stop for your sink, they have a nice brass t fitting that will adapt to whatever you have under your sink either 3/8 or 1/2. it included an isolation valve so you can easily turn off your filter system for maintenance and carriage replacement. As a plumber I was very pleased with install. I am very picky in the way I put things together and it still only took me about an hour or so. I bet you could do the job in 30 minutes if you were in a hurry. Parameters: my tap water has any where from 250-400 ppm total dissolved solids (TDS). That's pretty standard for municipal water in southern California. still that is allot of stuff dissolved in the water including lead, arsenic, chloramine, and trace chemicals. Ph from tap is about 7.8. Coming out of the RO membrane before it hits the Alkaline cartridge I got a TDS of about 9-14 ppm. That is pretty incredible. the finished Alkalinity from this system was 8.8! perfect alkaline water. the mineral content was a great also, about 40-60mg/L of Carbonate hardness and 60mg/L general hardness. That means the perfectly minneraled and alkalized water free from chemicals, heavy metals or any harmful contaminates. The flavor as you can imagine is incredible. I use it to brew beer with, my friends cant believe the quality of my brew, the secret is the water. I use it to brew kombucha with similar results. I use it to fill my fish tanks, the African Cichlids need the high Ph. Finally the customer service for iSpring is impeccable. I bought a cartridge replacement and has some issues, customer service was quick to handle my issue and did not cost me a dime to make it right. these are the genuine replacment filters and they make the system work as it did the day I installed it
