Most under sink water filters need cartridge replacements every 6-12 months depending on your water quality and water usage. Reverse osmosis membranes usually last for 2-3 years.

Is reverse osmosis water better for you?

Yes.
Reverse osmosis (RO) is one of the most commonly used and thorough ways to purify drinking water. Most purified water sold in the market is filtered with this technology.

According to the CDC, "Reverse Osmosis Systems have a very high effectiveness in removing protozoa (for example, Cryptosporidium, Giardia), bacteria (for example, Campylobacter, Salmonella, Shigella, E. coli), and viruses (for example, Enteric, Hepatitis A, Norovirus, Rotavirus." It will also "remove common chemical contaminants (metal ions, aqueous salts), including sodium, chloride, copper, chromium, and lead."

Because the critical membrane filter of a RO system removes harmful pollutants and a few helpful minerals, a standard 5 stage RO system will produce slightly acidic water with a pH of 7.0 or below. Some RO systems like iSpring RCC7AK remedy this by offering an extra alkaline remineralization filter that restores healthy minerals and provides a balanced pH. This will give your water a more natural taste than the regular 5 stage RO water filters will. You can refer to this article to learn more about reverse osmosis water and alkaline water.

Do electronic water Descalers really work?

The following timetable can be observed for performance evaluation of iSpring ED2000 electronic water descaler for the first 90 days.

Day 1:
On day 1, you can observe that the soap lathers more quickly and more effectively as the ED2000 action instantly begins to slacken the prevailing scale in the cold and hot water systems.

After 1 week:
Breaking down scale on water pipes, water heater elements (immersion rod heaters), and tanks, you may observe some tiny particles in the water coming from the hot water tap, although most of the broken down particles will be microscopic and can’t be observed by the naked eye.

After 2 weeks:
Loosening of scale on showerheads, faucets, kettles can be observed. Wiping plastic, ceramic, metal, and glass surfaces becomes much more easier. Soap and detergent required for bathing, cleaning, and laundering are significantly reduced.

After 1 month:
With the loosening of scale from the water heating system, it should take less time to heat the water. The amount of scale on pipes, faucets and showerheads should be significantly reduced.

After 3 months:
Disappearance of scale from the showerhead. The scaly crust in toilets is significantly reduced. No new crust should form. Depending upon the age of scaling and hardness of water, it may take up to 12 weeks for these effects to appear.

Please note:
1) The ED2000 is NOT a water softener and does not REMOVE calcium or magnesium from the water.
2) High Iron level (insoluble and soluble) in water can deteriorate and degrade ED2000’s electrical field operation, decreasing its efficiency on reducing scale. Under such circumstances, it’s recommended to use an iron removal system to remove the iron before using ED2000. If iron levels are above 0.3 ppm (parts per million), an iron removal system should always be used.

What is the difference between a water softener and a descaler?

The major difference between a water softener and a descaler is that a softener removes calcium and magnesium from water while a descaler doesn't. Water softeners use ion-exchange resin to soft water; thus, if you have a water softener at home, we recommend installing a reverse osmosis system for drinking water to remove excess sodium in water. In comparison, water descalers won't add extra ions into the water.

Are sink water filters worth it?

Yes.

Chlorine is a commonly used disinfectant in the treatment of domestic tap water due to chlorine’s competitive market price. Chlorine does an excellent job of disinfecting bacteria, microorganisms, organic matter, inorganic substances, and other harmful chemicals; however, not all of the chlorine used in the process is adequately filtered out. Some chlorine remains in the treated water that comes out of your home’s taps.

What is the best electronic water descaler?

iSpring ED2000 whole house electronic water descaler. It uses a patented computer chip to emit an electromagnetic wave that matches the resonant wave frequencies in the water molecule clusters. This causes the clusters to break down into active twin molecules with a much larger surface area and better bonding capability with the hard mineral ions. The water molecules in their new state can pick up and carry the hard mineral ions, significantly reducing the likelihood that they form scales and adhere to pipe surfaces while allowing the existing scale to begin breaking down.

Benefits
No salt added.
No maintenance is required.
No plumbing modification is required.
