Great value and customer service

I was replacing the filters from the ispring water system, first of all, I LOVE this system, cleanest water, and works. The filters are also super affordable which is key to keeping it maintained. I saw the new reviews about the change of format for the 5th stage filter, the company has fixed this problem by shipping new valve fittings which are easy to connect. I had my ice maker line hooked up to it and needed two double ended valves, trying to add the old valves to it, I damaged to filter ends. The company responded super quick to my emails, and are sending me a replacement filter and the 2 double ended valves I need. It was easy and a show of great customer service. I’ll update to let you know if the new 5th stage filter leaks (the other new stages have not leaked since installation)...which I saw some complain about. It is key to make sure lines are not angled or bent going into filter connections, something totally easy to adjust, I’ve never had my system leak on me. I’ll continue buying these Filters. Also, I’m just a mom doing everything by myself...so it’s easy.

Good product, with assuring quality.

I purchased my iSpring RCC7 system from Homedepot because it was out of stock on Amazon. The filters seemed to have worked well. My local water quality is rather poor, with a TDS level over 500. I used HM Digital TDS-4 meter to test the water from my local grocery store's RO machine, and my own iSpring RCC7. The RO water from my local store has a TDS level of 7. iSpring RCC7 gives 28. Quite satisfactory. Taste-wise, my wife and I couldn't tell much difference between the two.

Nothing tastes as good as the water from home

Is it weird to be proud of the water from your home? Cause I am! Ever since installing the iSpring RO system I have become a water snob. Nothing tastes as good as the water from home! I used my original filters for a year and don't really regret it but will change the next set out sooner. It's juts my wife and I so we don't use as much as large family would be there was still a good amount of sediment in the filters when replacing them. Obvious they are doing their job.

For us it was easy to see the benefit of these when you remove ...

Have had our iSpring filter system for a year with no issues and it was time for some new filters. This set contained 7 filters (3 you change every 6 months and the inline which is once a year), it does not contain the actual RO membrane (much longer replacement period). For us it was easy to see the benefit of these when you remove the first filter, in just 6 months it had gone from white to reddish brown (eww!). The water quality on this system is great and much cheaper than alternatives.

Easy to change

This is just an original cartridges for replacement. Easy to change. The hard thing is to determine that you need a replacement. As I changed the filters first time I found so much dirt on it, while the taste of filtered water still was perfect. I did not changed osmotic cartridge. It has been two years since that change and water is still perfect. I guess it is time to change filter again. I was asked to leave the review by Nick from iSpring, but review only reflect my opinion. It is a good product and I will buy again when I need a next replacement.

Affordable and Effective!

The iSpring water filtration system has been incredible! Our water has never tasted better and the customer service is top notch. Nick contacts us regularly to check in and see that we are satisfied. I knew these filters must be working but I didn't realize how well until we did our first filter change. Wow! Gross! I've included a picture of the first stage filter that is now completely Brown and yucky and was bright white when we first put it in. I can't believe we went all those years ingesting all that nasty water! If you're like me and don't want to have to use water bottles constantly (major environmental issue and expensive!) But also don't want to be relying on City tap water, this is by far the most cost effective and wonderful solution I've found. The system is very affordable and replacement filters are too. Highly recommended!

So far, so good

I bought this replacement set for my iSpring 5-stage Reverse Osmosis system. It comes with 6 pre-filters (2 sets of 3), which you are supposed to change every 6 months, and 1 post-filter, which you are supposed to change every 12 months. What that means is you have enough pre- and post-filters to last you a year. The RO membrane does NOT come with this replacement set because it should only be changed once every 2-3 years. Replacing the filters was relatively simple. First, you need to get on all fours under your sink (or wherever your RO system is installed) and turn off your water supply both from the tap side and the storage tank side. Then find each of the three housings containing the three different pre-filters and remove one at a time by turning each counterclockwise. It may require some oomph to get them going or you can just use an adjustable pipe wrench. Don't forget to lay some towels underneath because each housing is filled with water all the way to the top, so some spillage is expected. Once disconnected, remove the used filter by simply pulling it out, clean the insides of the housing with a paper towel, make sure the rubber gasket is still in place and replace with a new filter, making sure to match the appropriate filter to the appropriate housing. Screw the assembly back on to the system by turning clockwise, turn on the water supply and you are all set. I have not changed the last post-filter as it's not time for it yet, but I've learned from some other reviews that iSpring has apparently modified its connection tubing such that it's either a hair too short or too long now and requires the purchase of an $8 connector piece from your local hardware store. Not sure if that's going to be the case, which is why I called my review "so far, so good." Can't complain about the three pre-filters, which took me less than 30 minutes to replace. Next on my to-do list is to buy a TDS meter to test the effectiveness of the RO filtration system as a whole.

Post Carbon Filter - Comes with Adaptor READ MORE

So, these filters work great. They replace the originals perfectly. Other reviews mention that the post carbon filter is different. They are correct. The original filter had a t-adaptor that screws in. That much is true. The new filter takes a single 1/4” tube. However, it comes with a T adaptor in the box. I wish I had known this before I ran to Lowe’s and bought one myself. Oh well. They provide the needed parts in the box. I assume the 1-Star Reviewers were just careless and didn’t notice the part.

Confidence in safe water. No plastic water bottles.

Considering the PFOA and PFAS that have found their way into our village water supply, we are grateful to have the iSpring water filter system. We drink from refillable containers and cook in our filtered water, confident that while the water company attempts to remove these carcinogens from our water supply, we can safely enjoy our filtered water at home and take it with us wherever we go. We live next to a county park and this Spring we filled multiple garbage bags with discarded plastic water bottles. We never have to buy bottled water (and add to the plastic pollution of the world) because we have our own source of safe good tasting water.
