Review: Whole House Filter with great quality and effectiveness! - I purchased this filter housing and installed the 5 micron sentiment filter. I noticed a huge improvement in our well water clarity and taste! I have a well with this whole house filter after an ISpring 50 micron pre-filter and before an ISpring UV light filter. I have noticed a very slight decrease in pressure but a huge improvement in our water clarity and taste. I did have a small leak in the connections. I found using the heavy duty blue teflon tape with three even wraps stopped the leaks without excessive tightening. The housing and bracket are very good quality and installation was easy. The only problem I encountered was that this filter and the pre-filter weren’t the same distance from the wall with outlets and inlets. I had to put a half inch spacer on the pre-filter bracket to get them to align. ISpring Customer Service (Michele) is amazingly responsive and has American Customer Service Representatives that know their products. Highly recommend this filter and ISpring Filters for the essential components to a filter system.
Review: Great whole home filter housing. - Great filter for my well pump feeding my house's water. The blue housing doesn't screw in completely so there's a small gap at the top. Nick at iSpring was helpful in ensuring me that was normal, and in fact there were no leaks once I turned on the system. I have no pressure drop from this and a sediment filter installed.

### ⭐⭐⭐⭐⭐ Can't recommend ISpring enough!
*by A***R on August 14, 2023*

ISpring is an outstanding American small business. They offer high quality products that are easy to install and work really well. Even the packing and shipping materials are high quality. What really sets them apart is their customer service. I have been talking to Don for over a year, he first reached out when I purchased a spin down filter to see how I was liking it and if I had questions. Our house is on well water and we get a lot of sediment, more or less depending on the time of year. Don has a lot of knowledge and has helped me get exactly what we needed to get our filter system in optimal condition. It's so hard to find exceptional customer service these days! I have recommended ISping to people near me and want to make sure the online community knows just how awesome they are! Whatever your water situation is, ISpring can help set up a system to provide the best water quality for your home.
