Rated 5 out of 5 by from Fantastic There is no more smell from our taps. Hot tub was unbearable before but not anymore.

Rated 5 out of 5 by from Excellent Product We did our research before purchasing our Aquasana system. We had a couple sales guys come in and test our water and tried selling us some high end $8,000 system. After comparing all of our options we decided to purchase the Aquasana Rhino 600 with the water softener + UV System. After having it installed I bought a digital water tester just like the one the high end salesman had to compare the Aquasana systems numbers to the high end system. I tested the number and believe it or not Aquasana system had better numbers. The tap water at our house was running in the 150's and after the install our numbers our down to 14. The high end system that i was considering had number from 16-20.The bottled water we buy have numbers from 10-14 so, now every bit of water that is ran through our house is to the equivalent of bottled water. It's a huge difference in everything from the softness of our hair and skin to the amount of laundry detergent we used at one time. You will not regret purchasing this system. AMAZING JOB AQUASANA!!!

Rated 5 out of 5 by from So far so awesome :) It's been such a great feeling being able to drink water directly from the facet! It's small changes like better water consumption (including what you're skins absorbing while showering) that makes a big difference in your health and happiness (better tasting coffee anyone?!) :)

Rated 5 out of 5 by from My water tastes great and I feel better. Aquasana water filter company does a great job on bringing clean water right out of the tap, no more plastic bottles and no more pollution!

Rated 5 out of 5 by from Great investment! I've had the whole house Rhino in my home for several years and am comforted by the freedom to drink clean water in my house (most don't have). It may be tough to make that kind of investment on the surface, but when you consider the big money we spend on health care and insurance, it adds up to only pennies! Don't trust your government to filter out all the nasties. Disease is expensive, even if you have insurance, so getting ahead of it with water filtration is very smart and a great investment!

Rated 5 out of 5 by from Easy to install filter replacements We've been using our Aquasana whole house filter for over 8 years. We recently replaced the main filter. The water quality and taste are exceptional. We couldn't be more pleased with this product.

Can the 600000 gal replacement tank be installed into a 300000 gal system?

Asked by: rog314
Yes, a 600,000 gallon capacity tank can replace a 300,000 gallon capacity tank! The only difference between the 300K and 600K tanks is the amount of filter media that is put into the tanks. So, a 300,000 gallon capacity tank has 50% less filter media than the 600,000 gallon capacity tank.

Hi, do you have to replace the whole tank or just the media after 300,000 gal. On the 3000? What, you just throw away the old tank? No just changing the filters? This is a disposable system?

Asked by: Hydrate
The whole tank is disposable the others have replacement filters in them.

Do we have to hire a plummer to replace the tanks or is this something that a handy person can do themselves?

Asked by: karen50
I installed my filter system with sch80 one inch pipe and unions. Makes it easy to replace components or tighten up.
