Filter Case

My original filter cases where blue but I ordered the semi-clear ones so I can monitor the filter condition without having to shut off, drain, and open the filter cases each time. I very much prefer the semi-clear cases over the solid blue ones.

Quality product and great service.

I bought the 4.5 Big Blue Canister Filter as a prefilter for our water softener. I didnt install it for several months due to the construction of our home being delayed due to the pandemic. When I did finally install the device it had a leak at the presure relief valve used when changing filters. I contacted Bluonics and the person I spoke to, Leily, was very helpful and immediately sent out the replacement part I needed. I received the part in a few days and after replacing the part the leak was gone.
So even after close to six months after my purchase, Bluonics was there with great customer service.


Having tried another clear filter housing from another brand, I would often have issues with the threads of the sump cracking due to heat and chilling fluctuations. So far so good this one hasn't had any of the same issues as it has better designed threads.


Love being able to see the filter and the pressure relief button makes it easier to change the filter
