The product comes with 3 FREE adaptors to ensure it fits all the common UK taps.



An ergonomic design of tap filter which still allows plenty of room in the sink/wash hand basin to perform washing and cleaning.  Advanced filter technology allows a service life of several months (depends on incoming water quality).

It is environmentally friendly as  it enables users to replace just the filters rather than throw away a perfectly serviceable filter housing.

The costs of replacing the legionella filters are significantly less than total product replacement which is one reason it is used extensively throughout the healthcare industry.

Why can’t we post the sample back to you, couriers must add to the cost of your product.



Laboratories are regularly audited to ensure they meet UKAS standards.  Samples must be marked with the time/date that they were taken and analysis must begin within 48 hours (max). The UK postal service is no longer guaranteed to deliver within this time period. Samples that arrive at the laboratory more than 48 hours after sampling are deemed Non-Compliant and should not be tested.



Wouldn’t it be easier to use smaller bottles, other companies just ask for 250ml but AquaCert send out 1 litre bottles.



Yes, it would be a lot easier!

However, the international standard for legionella testing is set out in the document BS EN ISO 11731:2017 Water quality - Enumeration of Legionella.

We don’t take shortcuts, our testing is 100% UKAS accredited and the results will hold up in court.

Taking smaller sample sizes or allowing more than 48 hours transit time is not recommended and the validity of the result  would be challenged if used as evidence in a law court.
