What Shell Water Systems sells

Shell Water Systems offers salt-based softeners with whole house filtration systems that remove harsh minerals and 97% of contaminants. Click here to learn more! Their filters remove chlorine and chloramines, herbicides, pesticides, organic compounds, bacteria, and water-soluble heavy.

What to check when buying water filtration

Buy filtration for a problem you have identified, not in general. Testing your water first tells you which type you actually need.

• What the filter is certified to reduce, stated contaminant by contaminant. Independent certification against a recognised standard means far more than a general claim about "purity".
• Filter type matched to the problem. Carbon handles chlorine taste and odour; reverse osmosis removes a much wider range and wastes some water; softeners address hardness and scale, which is a different problem again; sediment filters handle particles.
• Flow rate, since a slow filter is a filter people stop using.
• Cartridge cost and replacement interval. This is where the real cost sits. Work out the annual figure before comparing units.
• Whether replacement cartridges are proprietary, and likely to stay available.
• Installation requirements — under-sink and whole-house systems may need a plumber, and in some places that is a regulatory requirement rather than a preference.
• Capacity in litres or gallons before the cartridge is exhausted, against your household's actual use.

Treat health claims with care. A filter reduces specified contaminants; it does not make water therapeutic.

Before you order

• Compare the total at checkout, not the listed price. Shipping and tax appear at the final step, and on a cross-border order duties are added later again.
• Check the delivery estimate against when you actually need the item, especially for a gift.
• Read the return terms for the specific item. Sale and personalised items are the ones most often excluded.
• Check the product page specification rather than the category description — size, fit and compatibility details live there.
• Keep the packaging until you are sure, since most brands require original condition for a return.
