When package arrived 1 of the sleeves was cracked.

Easy installation!! We were borderline on the cryptosporidium but I am sure this product will take care of the issue!!

UV Bulbs

They were not broken when delivered as has happened before so I am happy

So far, it appears to be working great! Please express my gratitude to the gentleman who called to discuss my filter needs period apparently, a 15 micron filtration rate, is better for my situation, then they 5 micron period thanks again!

These filter work very well.

Carbon filter

Now that I’ve finally been able to get the men to install two carbon filters, and one thread, I’m pleased to report that it’s gotten the rest of the odor out of the water. I was going to return a whole box full of the filters, but by the time I pay the shipping on it, I might as well just hang onto them even though I won’t have a need or use of them. I hope these filters last more than two weeks, before I have to change them out again.

Well water cartriges

Great quality at good price
Thank You

Great Product

I live in a mobile home in Southern CA. The local water does not taste that great. Also making ice cubes in silicone ice trays, they are tough to remove due to hard water making ice stick to the trays. I installed the single 4 stage 10000 gallon 3 year filter under my kitchen sink. The water now tastes much better, and the ice no longer sticks to the ice trays. The filter works great and is connected to the existing sink faucet with no loss of water pressure. On my installation on the filter output I installed a splitter to also supply my refrigerator ice maker. I also installed an inline water meter between the filter and faucet / refrigerator feed so I know when I get to 10000 gallons.

Bought 3 now.

I have bought and the installed three of these units. Now. They're easy to install and they work great.

Good filters, at a good price with fast shipping. Thanks

set this 3 stage system w/ UV, up on a new home with municipal water. The first thing I noticed was absolutely no chlorine order. Friends came in and said how great the water tasted. No rings in the bathrooms, the cloths are cleaner no build up in the showers. Very cost effective and a fantastic product.

O rings to stop leaks

Older system began leaking. O rings apparently decay over time. New O-rings fixes leak. Fast delivery, excellent help finding correct product. Hopefully buying multiple will keep the problem at bay, but if not I will return and buy from Bluonics again.

20" x 2.5" Sediment & CTO Carbon Replacement Filter Set for our Triple System

Good system

Everything you want in a water system has excellent value. Not hard to install everything color coded. Take your time and push the fitting in till you know they reach the end. The tank valve will leak if you do not tighten it all the way o the tank body and use lots of tape at least 8 wraps. Produces some of the best I have got from my well
