- Geekpure 20-Inch Universal Compatible Carbon Block Water Filter Cartridge for Whole House Water Filter- 4.5 Inch x 20 Inch

This filter cartridge is exactly what I needed. It's universally compatible, making replacement a breeze, and it effectively cleans our water. The quality is solid, ensuring long-lasting performance. Great value for maintaining a clean water supply!

this filter stopped a lot of impurities in my water before it went thru the softner. lasts about 8 months for me.

Bought cheaper than the one sold locally. Saved over $10. Needed to replace my old one that lasted from Nov - Jan on a house with a well that smells like sulfur. Made a big difference. Didnt want to spend a lot of $ on a sulfur removal treatment but this is a good alternative. I would continuously buy this and from this company. This will last for another 3 months.

Our utility sometimes overdoses water with chlorine, and it kills my water softener. I am using this to remove Chlorine from water before my water softener.

Great filter. Easy to install.

Works fine in my Whole House 20 inch Pentek Big Blue Filter Housing. I've used the Pentek EM-20BB cartridges for the last 10+ years but thought I'd try this Geekpure filter which was 35% less expensive. At a flow rate of 8 GPM there is a 2 psi pressure drop which is the same as the Pentek filters upon initial installation. The old filter I replaced was at a 3-4 psi drop at the same flow rate after being in service a year. I have pressure gauges installed ahead of and after the filter to monitor pressure drop. Feed water tested 1.3 ppm Free Chlorine and 0.1 ppm (or less) after the filter at that 8 GPM flow rate. We'll see how it goes.

Drop in replacement. A lot cheaper than what the service company wanted.

I am single, and I use this as a whole house filter. I replace it around my birthday every year. It works great. I live in a rural neighborhood, my neighbors will complain about the water's chlorine levels assaulting them, and the water being undrinkable - I NEVER notice a chlorine smell. Ever. My friend stayed in my house while I traveled and she commented on how much nicer it is to shower at my house than her rental, and how much nicer her hair comes out, because my water doesn't have the chlorine. This year, at changing time, I thought I caught a slight whiff of chlorine just before I changed the filter - telling me that my annual change-out is right for my usage level. The old filter was rusty looking - so I know it was taking out more than just the chlorine. I am very happy with this product.

Bought two, quality built units from what i can tell, one came chipped on the edge but the carbon was not damaged and was OK to be used. Water has no chlorine smell, they seem to be working good, time will tell if they last as the other brand.

Does a good job

Been purchasing these filters for years. The rated working pressure has reduced from 115PSI to 100PSI. Perhaps not at the fault of the supplier but the manufacturer of the filtration media. This info should be added by the seller to the listing. Time will tell on how long this filter will now last.

fit perfect, and is nice improwment in water flow and quality for drink

Well, it has not leaked. And everything seems to be functioning properly. The length was identical but the diameter is about almost a 1/4” smaller than the original. I don’t feel that is a problem I guess time will tell. I am so far very happy with the purchase. Really I can’t taste any difference. So that should be a good thing. Everyone who tries our water says it tastes different than their regular tap water and they like it. So somethings working. 🙂 I will update in a month.
