Online water filter shop with refill reminders

Households, landlords, small offices and cafes that want an easy way to reorder the right filter.

Profit on each product sold, plus repeat orders as filters need replacing every few months. Bundles and subscriptions can raise the average order.

• Basic online selling
• Careful with product compatibility
• Customer service by email
• Organised stock handling

• Check that any filters you sell meet relevant product standards and that suppliers can provide documentation
• Be careful with health claims about what a filter removes, and only repeat what the manufacturer can back up
• Consumer rules on returns and distance selling apply to online sales, so check the current guidance
• Cheap copycat cartridges may not fit or perform as expected, so check your suppliers
• Check whether you need to register for VAT as sales grow

Estimates suggest typically around £500 to £3,000, depending on the range of filters you stock and how you set up your shop. Check suppliers carefully, as cheap copycat cartridges may not fit or perform as expected.

Monthly revenue is typically estimated at around £300 to £3,000, depending on your range, pricing and how many repeat customers you build. Estimates suggest at least about 6 hours a week of work.

Check that filters meet relevant product standards and that suppliers can provide documentation. Be careful with health claims, repeating only what manufacturers can back up. Also check consumer rules on returns and distance selling, and VAT as sales grow.
