Quick questions
How often do I change the refill?
TAPP says every 6 months, or after about 8,000 to 12,000 litres depending on your water. Change it at 6 months even with light use, as the brand says the media can build up bacteria over time.
What does it cost to run?
The starter pack with the filter and one refill was £54.90. The annual subscription is £79.90 in year one (filter plus two refills), then £45 a year, and can be paused or cancelled any time.
Is it hard to fit?
TAPP says it needs no tools or plumbing skills and does not reduce water pressure. The page does not list the thread size, so check it suits your shower hose before ordering.
What warranty do I get?
A 2-year warranty with a one-off purchase, or a lifetime warranty while you keep the annual subscription. Keep your order confirmation, as you will need it for any claim. Refills are also sold on their own at £54.90.
