Cartridge Filter 10 inch (Pack of 10)

1. How many litres of water can I filter before I need to change out a cartridge?
There's no single number that fits every case — service life depends on the filter's micron rating, its efficiency at that rating, surface area, and the amount and size of solids in your water. As a general benchmark, this 5-micron cartridge is rated for up to 2,500 litres under normal TDS conditions.

2. What micron size filter should I buy?
It depends on what you're filtering for — finer micron ratings filter better but clog faster, shortening service life. This cartridge uses a 5-micron rating, the standard balance for most domestic RO systems.

3. Why buy a pack of 10 instead of a smaller pack?
At roughly 2,500 litres of service life per cartridge, a pack of 10 covers around 10 replacement cycles in a single order — ideal if you're maintaining multiple purifiers (a home plus office, or a small property manager handling several units), or simply want to stop reordering for a long stretch. Pearl Water's bulk pricing also applies at this quantity (5% off at 4 or more), bringing down the per-unit cost compared to the Pack of 3 or Pack of 2.

4. What size housing does this cartridge fit?
25 cm (10 inches), designed for standard 10-inch filter housings used across most domestic RO and UV water purifiers.

5. What is this cartridge filter made of?
Polypropylene (PP) — a synthetic micro-fibre material, melt-blown into thermally bonded fibres that trap sand, dirt, silt, and rust.

6. Will 10 cartridges go bad before I use them all?
No — shelf life is 24 months from manufacture, so buying in bulk doesn't mean the later cartridges degrade before you get to them, provided you store them normally (cool, dry place).

7. Is this cartridge compatible with my RO purifier?
Yes — standard 10-inch housing dimensions make it compatible with most common domestic RO and electric water purifiers available in India.

8. Is a pack of 10 meant for commercial use, or is it fine for a single home?
Either — this is the same cartridge as the smaller packs, just at bulk quantity. It suits a single household that wants years of stock in one order just as well as it suits multi-purifier or small commercial use.
