Need recommendations on a DIY 3-stage whole home water filtration system.

Considering the Express Water Essential model. Anyone with experience with this one?

Are the Lowe’s/Home Depot brands reliable? Any others?

LINKI installed an iSpring system about 2 years ago. Depending on what you’re looking for, the filter combinations can be configured to your preference.

I also installed an inline sediment filter before the main filter manifold. Just a little cheap one from Amazon with a brass housing and a cleanout 90° switch on the bottom.

I also jumped a ground wire around the manifold in the case something was grounded on one of my older pipes that I didn’t know about.

It was a super easy install. I ended up using a pro press for all the fittings. Also make sure to add a bypass with shutoffs before and after the manifold.

I'm fortunate enough to be in a water system fed by one of the purest aquifers in the country. Their annual water reports are damn near perfect.

I second ispring.

Did the whole install diy with a 50 micron sediment filter upstream of the filter.

I have pressure gauges on either side of the setup. Change filters about 1x every 6-8 month when the pressure drops too far.

I did the whole install with pex B and crimp fittings in less than 3 hours.

Works great. The amount of dirt/mud that gets caught is disgusting. Water tastes better too.

I believe the suggested time is 6mo. If you do the large sediment filter as one of the options on the 3 filter main manifold system, you can most probably leave that one for a while. It’s huge. The other 2 filters are your choice that you can pick from.

I would suggest getting a water test if your existing to see where you are before making the filter decision.
