We've had our Aquasana purifier for only a short time, and really enjoy the clarity and taste of the water. I'm not plumber-skilled, so installing was somewhat of a challenge, but the deed is done and we're very happy.
I love my Aquasana water filter; the water tastes great and it is so convenient. I am on the water-for-life plan so don't have to worry about remembering to change the filters, I am reminded of when it is time. The effort of installation, which I hired someone to do, is worth the gains in having the unit.
Pros: Clean taste, Durable, Easy to clean, Long lasting filter
It would be GREAT if they would offer an RV installation kit separately. My trailer uses PEX, so I found a Shark Bite T the perfect size and installed the entire Aquasana filter in about 1 hour (including drilling the sink for the new spigot) without any unusual tools (didn't need a Pex clamp with SharkBite T). Since RVs move around a lot, water quality is constantly questionable. This filter system reduces dramatically the variability of water flavor and quality.
The fixtures for attaching the tubes to the the house-side and filter-side hardware have several options. Much better parts breakouts with clear examples of how the several options are best composed should be clearly illustrated and in a scale that one can actually read. Additionally, because it is likely that some installations may require longer tubing, clear explanation of good locally-obtainable tubing choices should be explained, e.g., copper tubing and other options free of leaching chemicals.
Tidy,compact unit. Beware that if ordering internationally the connecting threads on the brass T piece may not be compatible for your region. The rate of flow is relatively low, likely due to having to pass through 3 filters. Very good value when comparing to other brands.
Pros: Clean taste, Easy to clean, Fast delivery, Good value, Long lasting filter
Cons: Difficult to install, Incompatible Threads, Slow pour
