Wonderful having full house filtered
Love being able to take a drink from any faucet and enjoy clean smelling and tasting water. Water pressure dropped significantly after 14 month. Swapped to find the old Olten cakes with sediment from the municipal water system in Washington DC. Will just make a pint of swapping it every 9 months. Yes, it’s a lot more expensive than using a drinking water filter for drinking water only. But we find the value to be well worth it. There’s clearly a benefit to our fixtures and plumbing. We’re confident that all of the water in the house has been well filtered. And we generally just drink more water when we can go to any tap in the house and fill up a cup rather than going down to the kitchen and pouring from a Britta filter.

Easy to Install
A friend of mine installed this for me. We had to refer to a video but it was very easy once we viewed it. I knew it was getting near the time to change the filter because my water was tasting icky. Within minutes my water was great again. This filter appears expensive but considering it is for a year, it’s definitely worth the money.

Good product
What a difference this product made with both the taste of our water and with water deposits on plumbing. Works excellent and super easy to change out the filter. Lasted a full year.

Expensive to maintain, hard to find replacement parts.
Very good product. It's built like a tank and does an excellent job. The reason for the low review score - it has a proprietary design and only one supplier (Watts), resulting in a very high total cost of ownership (For example, carbon filters cost $190+ per year! Carbon filters should cost $20-$30 max). This also results in very few retailers holding replacement parts in stock, which means that every year, trying to find replacement parts is an adventure.

Direct fit, effective
This was a direct fit for my system. The filter set is effective but a little pricey.

I bought the “opened package” option and it was fine. Saved me $60!
Best filter on the market. Easy to replace cartridges. Scary what’s in our water. When I replaced mine the year old filter was orange!

Works great!
Works great for our household water from taste to slowing down calcium deposit on faucets and water heater.
