Please Note:
This water softener DOES NOT have a built-in sediment filter. So if there is a lot of sediment in your water, we recommend installing a pre-filter such as iSpring WSP50ARB sediment filter before this system.
Iron would negatively impact the effectiveness of water softener and we highly recommend installing an iron filter before this system if there's iron in your water. Please check out iSpring WCFM500K whole house iron filter (3ppm < iron level < 12 ppm) or iSpring WGB32BM / WGB22BM / WGB21BM whole house iron filter (iron level < 3 ppm).
This water softener uses salt to soften water. If you want a saltless water descaler, please check out iSpring WDS150K, iSpring ED2000, or iSpring WSP50-SL water descalers.
You SHOULD NOT drink the water from any softener. If a water softener is necessary because the water is hard, we recommend adding a reverse osmosis drinking water system (like iSpring RCC7AK RO system) in the kitchen to remove the sodium that the softener leaves behind.

Highlight Features
-
Protect your family and household appliances
The innovative catalyst filter media in iSpring WF150K provides great protection to your family and household appliances - not only removing chlorine, lead, hydrogen sulfide (H2S, rotten egg smell), heavy metals, pesticides, herbicides, etc. but also inhibiting the growth of scale.
-
Personalize the System Based on Your Situation
With the digital screen and smart control valve, you can easily set the self-cleaning intervals based on your water quality, family size, and preferred time. If there’s a change among the factors or you want to start a regeneration immediately, all you need to do is to press a few buttons. It’s all about YOU.
-
Self-cleaning and Regeneration
The first step of backwashing removes contaminants attached to the filter media, restoring the filter’s performance and extending its lifespan. The second step rinses the media to get rid of the dirty water from backwash, refreshing the filter for future water purification. Both steps would be performed automatically based on your settings. Once set, you can sit back and enjoy crystal clear and clean water from every faucet in your house for 5 to 10 years.
-
Improve your Quality of Life
Upon purchasing the system, you are investing in a crystal clear life and a peace of mind. Cooking, bathing, and washing clothes with filtered water keeps you away from bad-tasting, smelly, and contaminated water. The purified water also helps to extend the lifespan of your plumbing system and the household appliances, releasing your burden on plumbing repair and replacements.

Please Note:
Although the unit may help with iron water issues, it is not designed to reduce a high level of iron. If iron is your main concern, please check out iSpring WCFM500K whole house iron filter (3ppm < iron level < 12 ppm) or iSpring WGB32BM / WGB22BM / WGB21BM whole house iron filter (iron level < 3 ppm).
