CFS 8 Pack 1 Micron Sediment Filter 20x2.5 for 9534-20 EC210

• EIGHT 1 MICRON CARTRIDGES - Sediment filter cartridges in the 20 by 2.5 in size, rated at 1 micron. Eight covers about four years on a six month change, and it is the lowest cost per cartridge on this page.
• ONE MICRON IS A FINE RATING - It holds far more of what a 5 micron cartridge would pass, down to very fine silt and rust particles. That is good for water quality and it means the cartridge loads faster on a dirty supply, so a coarser stage ahead of it helps on well water.
• SEDIMENT ONLY - There is no carbon in this cartridge, so it does not treat chlorine, taste or smell. What it holds is particulate: sand, silt, dirt, rust and loose scale. If taste is the problem you are solving, a carbon stage belongs behind this one rather than instead of it.
• PART NUMBERS AND HOUSINGS - Replaces 9534-20, EC210, EV9534-20, E-20 and 13459 positions, and fits standard 20 by 2.5 in housings. This is the slim 2.5 in diameter body, not the 4.5 in big blue; measure the cartridge you are replacing before ordering.
• MATCH THE FILTER TO YOUR WATER - How fast a cartridge loads depends on your supply and how much water the house uses. Well water or heavy sediment typically means changing sooner; light municipal use typically stretches the interval. Falling pressure at the taps is the signal to change it, not the calendar.

Eight sediment filter cartridges in the 20 by 2.5 in size, rated at 1 micron, for the 9534-20 and EC210 positions. Eight covers about four years on a six month change and is the lowest cost per cartridge on this page, which suits a well, a rental property or anywhere several housings come due at once. One micron is a fine rating. It holds far more of what a 5 micron cartridge would let past, down to very fine silt and rust, which is good for water quality and also means the cartridge fills up faster on a supply carrying a lot of dirt. On well water or anywhere the sediment load is heavy, running a coarser cartridge ahead of this one takes the bulk out first and lets the fine stage last longer. It is worth being clear about what this cartridge does not do. There is no carbon in it, so it does not treat chlorine, taste or smell. What it holds is particulate: sand, silt, dirt, rust and loose scale. If taste is the problem you are trying to solve, a carbon stage belongs behind this one rather than instead of it, and running sediment first is what keeps that carbon working longer. Check the size before ordering. This is the 20 by 2.5 in body, the slim diameter, not the 20 by 4.5 in big blue. The two are the same length and look similar in a photograph, and they are not interchangeable. Replaces 9534-20, EC210, EV9534-20, E-20 and 13459. How long it lasts depends entirely on your water and how much of it you run, and falling pressure at the taps is the signal rather than a date on the calendar. This is a compatible replacement, not an original manufacturer part.
