Filter media does its job by holding on to what it takes out of your water. Over time, it fills up.
💧 Keeps performance high
A fresh cartridge brings your filter back to full strength, so it keeps reducing chlorine, chloramine and more the way it did on day one.
😋 Keeps taste crisp
The first sign a cartridge is tired is usually taste. Swap on schedule and every glass stays clean and fresh.
🚿 Keeps flow strong
Spent media slows water down. A new cartridge restores a steady flow from your Trinity, tap and shower.

Quick answers about swapping your HolyH₂O cartridges.
As a guide, every 6 to 12 months depending on how much water your household uses. If the taste changes or the flow slows, it's time for a fresh set.
Every 3 to 6 months, based on how many people use the shower. A couple usually lands around 6 months and a family of four around 3 months.
The easiest signs are a change in taste or smell, a slower flow, or the chlorine smell coming back in the shower. A subscription takes the guesswork out by sending them on schedule.
Not at all. Every HolyH₂O cartridge swaps by hand in a couple of minutes, with no tools and no plumber.
