It’s an aquasana system. Master plumbers can install it and you should have them asses your house before you order it. You can install the system in some tight spaces but it isn’t ideal. It’s installed where the water enters the house and mine is two smaller filters and one 5ft tall tank. I change the pre filter every two months (it turns brownish yellow), the post filter is every 6 months, the main filter is good for 6 months. They auto send the smaller filters.

The water tastes great and I’m happy I did it. The system is about $1600 and the install was about $1000 so not cheep, but it’s worth the piece of mind. You can also get under sink systems for less. I did not get the UV filter or any bells and whistles.
