Pentair EF-3000 Series

The middle child of the EF series, it’s used to being ignored. But, like a lot of middle children, it’s strength comes from its ability to compromise.

Need a full flow filter that can block things at 0.5 microns? And one that is certified by the NSF under standard 42 (for taste/smell) and 53 (for blocking cysts)? And one that would last two people for a full year? And won’t need a separate faucet?

…okay so maybe this filter isn’t that good at compromise.

What about changing the filter? How often should I do that?

We could spend hours talking about gallons and average family usage, and all kinds of variables.

But, simply put, you should replace it when the water pressure starts to slow down OR when it’s been more than a year. 

You can push it past a year, if you really want to, but once you start getting into the year and a half to two year range, I’d start to get a little skittish about safety.

And changing it is as easy as changing a light bulb.

First, flip the handle up to shut off the water. Then, twist the cartridge (lefty loosey) and pull it out.

Then, take your replacement, push it back into the head and twist (righty tighty). Flip the handle down to turn the water back on.

Then, run the tap for a few minutes to flush out any dust or little bits. And there we go!
