## Description

AO Smith AO-WH-PREL-RCP - Carbon Sediment Filter Replacement 4.5 Inch - 5 Micron Filtration : desertcart.ae: Tools & Home Improvement

Review: Good value and performance - I have this as a pre treatment filter on my well water and it does a fine job of removing fine particles from the water before it reaches the softener system. I replace it every 6 months. Reasonable cost for the protection provided. Not sure the carbon is enough to really do anything beyond a short period of time, but the 5 micron filtration is great.
Review: Works very well in my home's water system - This is one of the better whole house filter cartridges on the market. I had bought them at Lowe's until they stopped carrying them; glad I found them on desertcart. My water quality is such that I change them quarterly.

*by K***E on 21 November 2025*

We use these in our sediment filter under our house. We are on well water and these filters do a fantastic job of removing sedimentation from our water. There is a big difference in the toilets, sinks and bathtubs. We have been using them for 3 years or more.
