Price

Cost will always be a factor when buying any new product for your home, although of course it isn’t the only factor to consider. 

 

When bought on subscription, the Curo Filtered Shower Head works out the most cost-effective option. You’ll pay just £56 if you sign up for the quarterly plan, although there’s also a great value annual plan that gives you the shower head and a full year of filters for just £130. 

 

Hello Klean and Water2 have similar pricing models, with great savings to be had when you sign up for a subscription. Hello Klean’s even comes with a welcome gift worth £20.

 

Replacement filters last the same amount of time (around 3 months) with each brand, and the price is also similar. Water2’s is cheapest at £29.99, but Curo can beat it in the first year with its annual plan - which includes the shower head and 4 filters, all for £130. 

Filtration System

The Curo Filtered Shower Head offers the most comprehensive filtration system, using a 3-stage process that removes over 99% of heavy metals and chlorine. 

 

Hello Klean offers a 2-step system which removes 90%+, while Water2 uses a proprietary Activated Carbon system which promises to remove the majority of chlorine, fluoride, lead and limescale. 

 

In terms of shower experience, Curo boosts water flow rate by 18% but doesn’t reduce water consumption. Hello Klean does offer this feature, cutting water use by an impressive 25%. Water2 only says that it ‘increases the feeling of water pressure’ according to user feedback, although this isn’t backed by any statistics.
