How long a cartridge lasts
Plan on about four weeks of daily showering per cartridge. Harder water, longer showers or more people in the household shorten that; light use extends it. Every IonDrops shower head arrives with a cartridge already fitted, so your first replacement is due roughly a month after the head arrives.
| Use pattern | Expected cartridge life |
|---|---|
| One person, daily showers, average water | ~4 weeks |
| Family bathroom, several showers a day | 2–3 weeks |
| Very hard or visibly sediment-heavy water | 2–3 weeks |
| Guest bathroom, occasional use | Several months |
How to tell it is time to change
- Colour. A fresh cartridge is pale. When it looks grey, brown or orange, it has done its job.
- Flow feel. If the spray starts to soften, the media is loaded and restricting flow.
- Odour returning. If chlorine smell creeps back into hot showers, media contact is exhausted.
Changing one in about 40 seconds
- Turn the water off. Turn the shower off and unscrew the IonDrops head from the shower arm by hand.
- Open the chamber. Twist open the filter chamber and lift out the used cartridge.
- Fit the new cartridge. Drop in the fresh cartridge, seat it flat, and close the chamber until it is finger-tight.
- Refit and flush. Screw the head back onto the shower arm and run water for 20–30 seconds to flush the new media.
Used cartridges are not refillable or washable — dispose of them with household waste.

How to buy filters
The simplest way is to tick the replacement-filter option in the order summary while buying a shower head — it ships in the same parcel with no extra shipping cost, so you are never waiting a month later. Multi-bathroom households usually add one 2-pack per shower head in regular use.
Filters are sold here on the official store only, which is also where the 90-day guarantee applies. If you are comparing sources, read where to buy Ion Drops.
Compatibility and specs
- One cartridge format fits every IonDrops filtered shower head and every bundle size.
- Media: filtration bed for fine sediment plus chlorine taste and odour reduction.
- Sold in sealed 2-packs; shelf life is not time-limited if kept dry and sealed.
- Sold in USD and shipped worldwide with tracking.
Troubleshooting after a change
- Cloudy first run. Normal. Flush 20–30 seconds; fine media dust clears.
- Drip at the arm. The washer has shifted — unscrew, reseat it, hand-tighten again.
- Uneven spray. Rub the silicone nozzles with a thumb to clear deposits.
- Pressure still soft. Confirm the chamber is fully closed and the cartridge is seated flat.

Frequently asked questions
How much are IonDrops replacement filters?
$14.99 for a 2-pack in USD. That covers roughly two months of one daily-use shower, so about $7.50 a month. You can add a 2-pack to any shower head order at checkout and it ships in the same parcel at no extra shipping cost.
How often should I change the IonDrops filter?
About every four weeks with daily use. Change sooner if the cartridge looks grey, brown or orange, or if the spray starts to soften — both mean the media is loaded.
What happens if I don't change the filter?
Nothing unsafe, but flow gradually restricts and the pressure boost fades because the loaded media slows water down. Filtration performance also declines. Swapping the cartridge restores the original feel immediately.
Can IonDrops filter cartridges be washed and reused?
No. The media captures sediment through its whole depth, so rinsing the outside does not restore it. Cartridges are single-use and go in household waste.
Do replacement filters fit every IonDrops shower head?
Yes — one cartridge format fits every IonDrops filtered shower head, including every bundle size, so you never need to match a model number.
How many should I order for a multi-bathroom home?
One 2-pack per shower head in regular use is the usual pattern, which covers about two months each. Guest bathrooms used a couple of times a month need cartridges far less often.
