Okay so I've been using these Ronaqua filters for about 3 months now and here's my real talk review:

First off - the sediment removal is LEGIT. Our well water used to leave this weird gritty feeling, but now it's actually clear? Like I can see the difference in my shower glass and coffee maker. The 1 micron rating isn't just marketing.

Install was stupid easy - just popped them into our existing housing. They fit perfectly with our system (we have the iSpring one). No leaks, no weird pressure drops like some cheaper filters cause.

The best part? Buying the 4-pack makes so much sense financially. We change ours every 4 months (our water is nasty) and having extras means no panic when one clogs up suddenly.

Only thing - wish they came with some kind of indicator for when to change. Right now we just guess based on water pressure, which feels kinda medieval in 2023.

Bottom line: If your water looks like weak tea or you're tired of cleaning sediment out of appliances, these actually work. Not glamorous but gets the job done!
