You can definitely tell the impact the filter has on the house. Attached is a before and after 4 months. Will be reordering and changing more frequently since it says that it can be changed every 3-6 months depending on your geography and amount of water sedimentation coming from the street i guess. I live in Puerto Rico and the water tends to be pretty sedimented. Works really well but the durability is not the best.

Works good. We were getting a bad taste from our tap water, this cleared it up immediately. Verify your filter length before ordering. There are 2 lengths on the market with a 1/4" difference

Just what I needed and I'll probably be ordering more

Half worked half didn't. It was a horrible experience. Taking my water pressure down to lower than 5psi on 3 of the 4 filters! These did not last for me. I was so disappointed no refund or promotion included. Sad to say this cause they worked really well for my first year supply. Really upset and would rather pay 15 dollars per filter at home Depot then pay for this again they were super disappointing. I buy a years worth at a time and these didn't even last me 4 months.Update on my review May 2025. If you have an issue they customer service is above par! Try your luck, they worked for me for over a year before they didn't but they sent me a replacement and after having another unlucky batch it seemed they refunded me my full purchase price. I would give them a try due to the excellent customer service.

Well packaged and do the job intended in my dual rv filter system.

I like that my house water is filtered to this level!

They work well

They worked great for our camper
