Slightly better than the water filter in your fridge

I am a repeat customer after purchasing the iSpring RCC7P reverse osmosis system. If you have the space, I recommend a reverse osmosis system. This built-in 4-stage filtration system is slightly better than the built-in water filter in a refrigerator. My water still has a metallic taste and a touch of tap water. I have a TDS meter and unfiltered water has a reading of 30 compared to filtered water which is 45. This test is done after a minimum of 100 gallons has passed. This system works for me

Pros
  • Great for me
Cons
  • Doubt

Do not buy "used " here! READ THE UPDATE!

I thought I would save money by buying my "USED" here at Revain. HOW WAS IT USED? My water tastes even worse! The chlorine and weird taste did NOT get better - they got stronger! All in all, I just bought a small stand, smoking pipe, and faucet for a few dollars less than a "NEW" set! SO CRAZY! I thought it would improve as it handles more water as some have said you have to leave it running but it got worse. Now I have to buy new filters and I am MUCH more than I would have spent if I had just

Pros
  • Absolutely amazing!
Cons
  • Incredible piggy bank

Questionable filter quality

I have been using this filter for more than a year and I am satisfied with its consumption, taste and reliability. A big BUT as I later got curious to learn more about what this thing actually filtered out. I contacted the company and they provided a chart showing what is being filtered out which looks like a DIY chart and it did NOT mention filtering the substances they advertise such as: B. arsenic, iron, nickel, chromium, cadmium, calcium, aluminum. , Mercury. This worried me that I was…

Pros
  • SIMPLE AND FLEXIBLE: NO WASTEWATER or water tank required. The CU-A4 offers high-efficiency water filtration for a wide range of clean water needs - at the sink, in the refrigerator, for coffee machines and more.
Cons
  • There are other interesting options.

My installation does not have Murphy's Law

As a retired tech writer, I agree that the manual requires some work to help customers with their installation, it's worse for newbies and people who don't normally maintain their homes. . I've done most of my home renovations so with this experience I'm a little better prepared for projects unless a professional is needed. Aside from pesky broken or missing parts, preparation is key. So for beginners, read the manual a few days before installation, make sure you have everything (like wrenches,

Pros
  • 4-STAGE ULTRAFILTRATION SYSTEM: Polypropylene sediment filter ((5 micron) removes larger particles such as rust, sand, dirt.) Ultrafiltration filter (contains a hollow fiber membrane with a pore size of only 0.01 micron). ) KDF and GAC filters (provides much better control of particularly problematic contaminants, including chloramine, hydrogen sulfide, heavy metals and other compounds). Fine filter with activated carbon (ensures the final polish).
Cons
  • Not bad, but...

What are the oily residues? Simple solution, thoughts.

Edit: 2.5 years and three sets of filters later still no problems to report. I've made a few changes below. Read #1 - Very Important! This is a great filter for those who want to keep the beneficial minerals in the water and filter out the rest. The best filtration is reverse osmosis, but it requires a separate separate storage tank to keep the water at room temperature, metallic taste, and low water pressure = slow flow. After extensive research, we chose this filter for all reasons. Above…

Pros
  • FILTERS EASY INSTALLATION AND REPLACEMENT: Push-in fittings with color-coded tubing simplify installation. Filter replacement is designed for simplicity. There are no hoses or water lines to disconnect. Just Twist On / Twist Off filter cartridges make changing the filter easier. Filter life: 6-12 months depending on source water and usage.
Cons
  • Packaging is ugly
