Our verdict on each
Cloud Water Filters
Cloud Water Filters suits US homes that want reverse osmosis installed under the sink and can live with a running cartridge bill of $200 to $250 a year. Cloud RO starts at $649 and carries a 5 year warranty, so the strength is certification and cover, not entry price.
Waterdrop
Waterdrop sells reverse-osmosis systems with a stated PFAS and lead reduction claim and support on chat, email and phone, which suits households ready to have a unit installed. The running cost is the trade-off: replacement filters at CAD 139 a set against a warranty of 1 year on the hardware.

Pros and cons
Cloud Water Filters
Pros
- Cloud RO carries full system certification under 58, with an added lead content test on top of the standard scope.
- PFAS and lead reduction is stated for the system, so buyers focused on those contaminants have a direct answer.
- A 5 year warranty covers the unit itself, not just the cartridges that come with it.
Cons
- The Cloud RO entry price of $649 sits well above a typical site entry price of €127.49, so it asks for money up front.
- Installation is required for the Cloud RO, so it asks for a fitting job, while the IBBL range is countertop for buyers who would rather set a unit on the worktop.
- Support runs on email, chat and help centre only, so there is no phone line listed for problems with the plumbing.
Waterdrop
Pros
- A stated PFAS and lead reduction claim, and the tankless RO model carries NSF/ANSI 42, 53 and 58 certification.
- A filter set is rated for 8,326 to 10,982 litres, well above the 2,512.5-litre median across the ranking.
- Support runs on chat, email and phone, a wider spread than the email-only setups common in this category.
Cons
- Replacement filters run CAD 139 a set, and the annual filter cost of CAD 139 keeps adding up after the CAD 339.99 purchase.
- The hardware warranty is 1 year, well short of the 8,326 to 10,982 litres a filter set is rated for, so cover ends long before the cartridge does.
- Installation is required on the range, so the CAD 339.99 entry price is not the whole cost of getting filtered water running.
Who each suits
Cloud Water Filters
Who it suits
- US homeowners with plumbing space under a sink who want an installed system rather than a countertop filter.
- Households that put certified contaminant reduction, including PFAS and lead, ahead of the lowest entry price.
- Buyers who would rather cover a system with a 5 year warranty than think about cartridge pricing every year.
Who should look elsewhere
- Shoppers with a tight opening budget, who will find entry points below €127.49 elsewhere on the site.
- Renters and anyone without a plumbing slot, since Cloud RO needs installation while the IBBL countertop units do not.
- Anyone outside US, or buyers who want to phone a company, since support here runs on email, chat and help centre only.
Waterdrop
Who it suits
- Households that want a certified reverse osmosis system with a stated PFAS and lead reduction claim.
- People who want phone and chat help as well as self-service, since support runs on chat, email and phone.
- Shoppers who filter enough water to spread the CAD 139 filter set across its 8,326 to 10,982 litres capacity.
Who should look elsewhere
- Anyone set on a countertop system, since IBBL builds in a different format and the fitting rule does not apply to it.
- Buyers who want the Culligan Consumer Products Aquasential Smart, Aquasential or Good Water Machine range, since Waterdrop's line is reverse osmosis only.
- Shoppers who would rather order from a European store, since Waterdrop (EU) lists its own X series and tankless RO models.

Questions about each
Cloud Water Filters
How much does Cloud Water Filters cost at the start?+
The Cloud RO system has an entry price of $649, which covers the unit itself. That figure sits well above a typical site entry price of €127.49, so it is the first thing to weigh against a budget. Running costs are separate and are covered by the yearly filter bill.
What does the filter cost to keep running?+
Cartridges are priced at $200 each, and the annual filter cost for a Cloud RO household runs $200 to $250. Those are the figures to plan around rather than the entry price. Cartridges are bought as they are used up, so the yearly total tracks household consumption.
Waterdrop
How much does a Waterdrop system cost to buy?+
Waterdrop's reverse-osmosis range starts at CAD 339.99. That is the price of the unit itself, with replacement filters bought separately afterwards. It is worth setting against the €179.99 median entry price across the ranking to see where the range sits before choosing a model.
What does it cost to keep a Waterdrop system running?+
A replacement filter set is CAD 139 and the annual filter cost works out at CAD 139. A set is rated for 8,326 to 10,982 litres, so the yearly figure moves with household size and the incoming water. Budget for filters from the outset rather than treating the purchase as the whole cost.
