    • Great filter, trusted brand, and easy to bypass Great filter, trusted brand, and easy to bypass

I’m very happy with the Culligan WH-S200-C Whole House Water Filter. It works great and has made a noticeable difference in my water, especially with reducing the amount of iron. Culligan is a good name brand, so I felt confident buying it, and so far it has lived up to expectations. One feature I really like is the built-in on/off/bypass switch. It makes changing filters or bypassing the unit much easier without having to shut everything down. Overall, this is a solid whole-house filter that does exactly what I needed it to do. I would definitely recommend it. Don't forget to have Alexa set a reminder for you to change it every couple of months! ... show more

I bought this water filter, and it has been an excellent investment. The water now tastes much cleaner and fresher, with no strange odors or flavors. You can notice the difference right from the very first use—especially when drinking water and cooking. Installation was quick and simple, and the materials feel high-quality. Plus, it gives me greater peace of mind regarding the water my whole family consumes. I highly recommend it to anyone looking to improve the quality of their home water in an easy and affordable way. ... show more

    • Higher quality, heftier than comparably priced filters.
Size: 3/4 Inch Style: Clear
Excellent high quality filter system. This is heavy duty compared to others at the same price from big box stores. The fittings are of high quality, the filter is larger than most other systems with a 3/4" inlet. The only reason for not rating it 5 stars is that there are only 4 screws included, which are used to attach the mounting plate to the unit, so there are no screws left to attach the mounting plate to the wall. ... show more

I’m using this Culligan Whole House Water Filter System for my ice machine, and it works great! The water is noticeably cleaner, and my ice comes out crystal clear without any odd taste. Installation was straightforward thanks to the built-in bypass valve and included tools, and I love that it helps protect both my ice maker and plumbing from sediment buildup. Culligan’s quality really shows, solid construction, easy maintenance, and peace of mind knowing my water is well filtered before it even reaches my appliances. Great price and fit perfectly, Highly recommend! ... show more

    • Good value and well made
Size: 3/4 Inch Style: Clear
I decided to install this instead of an under sink filter. Filters the whole house and cold/hot water. Only issue I had was finding good mounting screws for a cinder block wall. Vibration from pump turning on and off loosened the mount in screws. Off-Bypass-On valve options are a nice feature.

We've been in our new house for a year now and are on a local water supply for the subdivision. We had smell issues in the water and pulled the anode rod from our 1 year old water heater, and it was down to the wire. I have since learned that the smell comes from the decaying zinc on the anode, but had already ordered this filter to prefilter anything that may be contributing to that smell. It's so nice to be able to see that we don't have sand or other debris in our water, and so far only see a rusty iron color on the filter, which is easy to view thru the clear canister. I used a couple of sharkbite fittings and intercepted the incoming water line before the softener and water heater, so our entire system is now filtered. After this, I added a powered CorroProtect, which I did have issues with, but now my water smells are history. Installation was easy and it looks fine where I installed it. ... show more
