Question: How long does this last? I have heard of similar systems lasting 4-5 years.
Document: I did alot of research and comparisons online form many sites regarding what is and isn't really filtered by different systems and the  Rhino rated hi almost universally. There is no taste in the water, it is cyrstal clear and I beleive it is helping the appliances like the washer and dishwasher last longer as well...whatever brand you pick, pick one..because it is cheaper and healthier then bottled and it is your long term health that I think is being addressed..btw.the company has ratings for 300000 gallons or 3 years per filter..but it actually rates out to almost 600000 gallons..simply test  your water for chlorine with a simple pool tester..it is undetectable when filter is  good..so you may get 5-6 years out of it
I have had whole house filters for over 15 years now...starting with a simpler home depot types and finally settling in on the Aquasana Rhino eq300, which i have had 2 of in the last 4 years. Firstly, if you don't have a whole house system, get one!..holy smokes..when you change just the pre-filters you will gasp at what you were passing thru your house ( and family ). My wife always saves one for her book group to see..this is the neighborhood water..
I have looked into other systems, and they cost more and do less, that's why I chose Aquasana.Downside to this system is probably the upfront cost, and the maintenance. If you don't have the acidic water, that will save you a lot vs. what I paid. As far as maintenance, you have to add soda ash to the tank periodically (monthly?) and change the pre-filter (1-2x a month?). But it's easy to do (5-10 minutes), you can do it yourself, and any system will require maintenance of some sort.Especially if you have a well, you need a good filtration system.
My husband and I tried everything to help our newborn's eczema. After spending much time and money on lotions, creams and medications, we decided to figure out the root cause of eczzema/extremely dry and irritated skin. To make a long story short we called the water company and found out that amount of chlorine put in our water was at the highest levels deemed to be safe. We then started researching whole house water filtration systems and decided that the aquasana rhino was the one for us. Within a week of installation our son's skin cleared up entirely!!!
This is a great whole house water filter solution. I have used this for a year and a few months now and zero problems so far. Only changed the sediment filters every 3 months very easy to do in less that 5 mins no tools required.This is a great product.
I purchased this via a reccomendation of a friend and installed it myself using simple 3/4&#34; Pex Tubing and located it in the garage.I removed a whole house water (Salt) softener system that was installed by the previous owner and after flushing the entire plumbing system there was a huge huge huge difference in not only the taste of the water, but the clarity, smell and feel of the water. My wife even commented on the difference in the feeling of the clothes after washing and drying them.
I didn't test water pressure. But it for sure will affect it. My house is 1", which was built 2001. My friend's new house has 1 1/4".The water does taste better as a result of active carbon in the blue tank taking the chlorine and odor. But if you spend 100 for a big blue cartridge with active carbon filter, you can get same result. Changing the filter every 6-12 months gives you more promising results. The simplesoft is totally useless. They gave fancy explanation that the Ca and Mg are somehow bounded by their stuff and would be less likely sticking to the pipe and appliance.
However, you have no way to see the difference or prove it. The water spots are still everywhere in the shower room and on the dishes.I was trying to search for some REAL review online, but didn't find any. Most searches link to their own site. I went to couple forums asking for feedback and heard nothing good. They just use the high profit margin making up a good image on the internet. Their shower head filter might worth the price. But definitely not this POE (point of entry) system.Anyway, after one month, I returned the whole system.
I love this system for city water in Houston. Our water smelled bad and all our appliances were suffering from the very very hard water. When we repiped our house with Pex A our plumber installed this system. AMAZING results without a water softener. We installed it in our front closet, and it made a huge difference fast. I swear it is the reason that after 15 years of hair loss, my hair grew back all of the sudden after this was installed.
I don't own this filter, I own this filter with an additional filtration element for hydrogen sulfides and it is awesome. It has provided crystal clear water for about three years under extreme conditions (local water is the crappiest well water ever seen). Amazon needs to list the replacement filter (less expensive), because it is all most people really need. I will replace this one with the same thing when the time comes.Aquasana EQ-300R Main Filter Rhino Replacement
Answer: Our system lasted about 5 years. I believe it might go longer if it weren't hooked into the sprinkler system. We do not have a bypass for that, nor can we add it. The tank is very easy to install, and to change the filters. So glad we have it!
