The filters are cheaper than the previous brands I have owned. Very good.

It was easy to change the fifth filter out, and it doesn't seem to leak since we got a working part.

Filters 1-3 (the lower vertical round ones)--replace 6-12 months (depending on your inlet source--wells or contaminated they recommend 6 months, otherwise 12).

I change the cloth & charcoal filters every year and the reverse osmosis filter every other year.

The first thing I noticed was the shipping packaging. You can tell a lot about a company, by how they treat their product during shipping. Every box fit perfectly in the shipping box, and everything was secured. Good first impression
Second was detail in set up. The instructions said to watch the YouTube video first. I was able to assemble the RO system via the video. It really was easy.
Once set up, no leaks, drips, or cussing. I rarely put something together without a £€~^##, along the way. Didn’t have any of that.
End result was delicious water, at the tap. Thanks iSpring for making our lives better.
