iSpring F3-RO500AK 1-Year Replacement Filter Pack for RO500 Series Tankless Reverse Osmosis Water Filtration System

Love the system and the company and Iris helped in sorting out the filter.. Assyrianme. Sun Mar 08 2026

The WSP series spin down sediment filter is the first line defense to your appliances. It protects and extends the life of your standard filters by removing the large dirt, sand, and rust particles before they reach the rest of your plumbing system, including water softeners and expensive appliances. The WSP series is flushable and reusable. It is recommended to flush it regularly (daily or weekly), depending on the water usage, sediment amount and the hardness level. However, as hardness tends to form hard scale that clogs the screen, simple flushes may not be sufficient. When necessary, remove the stainless steel cartridge and clean it with a brush and/or soak it in vinegar. The WSP spin down sediment filter comes with a variety of options in micron size.Smaller microns allow less through, but to get most life and efficiency out of your filters it’s important to only go as small as you need. Differences in water quality and your water pressure affect the performance of the WSP.

The Ispring ED2000 whole-house electronic water descaler is an innovative, computerized water conditioning system that solves hard water problems without the need for chemicals, salt, or filter cartridges by leaving the minerals in the water and preventing them from forming lime-scale deposits. It requires little maintenance as it does not need the constant salt additions or cartridge replacements that traditional water softening systems require. The ED2000 functions by wrapping 2 antenna cables around the main water pipe to form a coil, creating a complex, frequency-modulated, and electronic magnetic waveform. The ED2000 functions by wrapping two antenna cables around the main water pipe to form a coil, creating a complex, frequency-modulated, and electronic magnetic waveform. This induces an oscillating electric field into the water, resulting in the agitation of water molecules sufficient enough to trigger the release of carbon dioxide and cause the premature precipitation of calcium bicarbonate. This process naturally results in a small increase in solubility, which allows the now unsaturated water to dissolve existing scale deposits and remove them from the water system.

It’s not the most expensive descaled but so far so good. Puts on a nice light show too. The manual is well written. This appears to be manufactured in Atlanta. Not thrilled about the wall wart power supply and would had preferred an internal version. Edit after a few months, my 20 year old plumbing has been descaling en mass. I replaced my water heater, also 20 years old. The water is coming out with the lime sentiment. It quickly settles. But I’m hoping it finishes. The product obviously works. But be ready for the purge phase. . .. Paul. St. Petersburg, FL. Tue Dec 20 2022

iSpring 20"X2.5" Whole House Water Filter CTO Carbon Block

The WGB21B is a great "point of entry" filtration system and an excellent alternative to the larger WGB22B for smaller homes. The WGB21B will filter water directly from your source. This means that water from every outlet will have passed through this filter, providing up to 50,000 Gal. of clean water for the entire family. The first stage of this system houses a 5-micron high-capacity polypropylene sediment filter (FP15B). This filter is responsible for removing dirt, rust, and most suspended solids, to protect the CTO carbon block filter. The second stage houses the 5-micron CTO coconut shell carbon block filter (FC15B). Block carbon is more effective than other forms of carbon in that it is finely ground up carbon packed into a solidified block. This means they have a higher density than other types of carbon filters and are therefore more effective in removing their targeted contaminants. The carbon block filter knocks out bad tastes and odors, removes over 90% of sediment and chlorine, and is highly effective on chemicals, like pesticides, herbicides, and industrial chemicals.

Looks like it should work well. Bought it to put on our 5th wheel but winter is here and camper is winterized. I will put it on in the spring. Can’t wait!!!!. Craig. US. Wed Nov 12 2025

This helps prevent large particles of dirt from clogging any finer filters you may already have in place. The WSP also includes a powerful anti-scale and corrosion agent called siliphos. Siliphos is a water treatment compound, a glass-like Polyphosphate containing Sodium, Calcium Magnesium and Silicate, formulated specifically for the treatment of water problems.

I've lived in this home for almost 8 years. The water about twice a year seems to be "shocked" with chlorine. Now my water test according to the state report is some of the cleaner in the state of NC, but the taste is horrible. The TDS tested at 43 and the chlorine was almost as high as pool water level. So my fiance and myself, after much research, decided on ispring. Cost, customer reviews, install and how it tailored to our issues were why we chose it. Chlorine was drying out our skin, causing itching, and damaging our hair and probably damaging our mitochondria if I had guess. Immediately after I got the whole house system installed and the system purged it was night and day. We've notice more energy, less stomach issues, our hair is easily brushed/combed. We can cook and bathe with the same tap water. I also added the RCC7AK for reverse osmosis to drink. The reverse osmosis water IS BETTER THAN ANY ALKALINE BOTTLED YOU CAN BUY!. Jamie.
