Do NOT Buy Until You Read This Aquasana Water Filter Review

Last Updated on March 18, 2021

The Aquasana water filter is one of the best brands of water filters available on the market today.

Aquasana Whole House SystemsGetting a water treatment system is not just useful but necessary if you want to get the best quality water at source that comes into your home.

The Aquasana Rhino is a whole-house filter system that can also act as a natural, “salt-free” water softener.

For example, when filtering tap water, there are usually two ways to do it. The first is to install a filter at the single point of use (i.e. at the top of the faucet) and the second is to install a water filter under the sink.

However, this means that you will only have filtered water at those individual points. All the other taps and faucets in your home will continue to provide you with unfiltered water.

The only solution to this is to get a whole house water filter that will purify all the water that comes into your home. This way you know that all the water in your home will be treated.

Standalone Salt Free AquasanaThe best part about this is that the cost of a whole house water filter will actually save you money in the long run.

You will never need to buy bottled water again, no pitchers, jugs, no shower filters and your appliances will be protected from hard water.

In this comprehensive guide you will find everything you need to know about the best Aquasana water filter.

At the end, I’ll explain why, in my opinion, the Aquasana OptimH2O is the best way to filter and purify water in your home.

Whole House Water Filter Buying Guide: 2 Essential Considerations

1. Water Flow

The level of water flow per minute depends on the type of water filter system you select.

Aquasana Whole House Features ListKeep in mind that this system will filter all the water entering your house through toilets, appliances, showers, and taps.

So if you have a small home, you may only need one water filtration system that can produce about ten gallons of water per minute.

A larger house needs more than ten gallons per minute. Therefore, it is important to know the water requirement so that you can ensure that the water filtration system produces a good water flow.

2. Filters

The right type of filters will depend on what pollutes your home water supply.

MyTapScore Home Water TestYou may need a filter system that is different from other houses depending on what level and type of contamination you have. A water test kit will tell you which is the best water filter for contaminants found in your water.

For example, you can use a regular copper-zinc mineral filter if you have a high level of heavy metal contamination. If you have severe bacterial contamination, you should consider a UV filter.

Aquasana Water Filter Review

Aquasana water filters are known to eliminate a number of common bacteria and heavy metals. Depending on the filter you select, it may be lead, chlorine, giardia, chloramine, cryptosporidium and others.

They also occur in all possible forms. For example, Aquasana offers filters for the whole house, under the sink, jugs, water bottles and water filters.

Aquasana Whole House Water Filter

The Aquasana water filter for the whole house is only available in a limited number of models.

One of the most popular whole house water filters from Aquasana is the Rhino and this comes in many different versions (but is based on the same model). For example, Aquasana Rhino is available in versions of 6 years 600,000 six hundred thousand gallons and 10 years 1,000,000 one million gallons.

In very simple terms, however, there are two major types of Aquasana water filters for the whole house:

  1. We have the Aquasana Rhino whole house system, but we are smelling a rotten egg odor from all our water taps. Does it filter sulfur bacteria? What should we do?

    1. Hi Josephine

      Unfortunately it’s not clear if Aquasana Rhino is capable of effectively treating high levels of sulfur.

      You might want to consider getting an additional dedicated sulfur filter as it sounds like you have a high concentration in your water system and most whole house filters only treat small amounts of sulfur – at best.

      Stay hydrated,

  2. Why doesn’t the Aquasana website mention that OptimH2O deals with arsenic but this article specifically speaks to it. Am I missing something? Help me understand. Thanks!

  3. Hi there, We are looking at the whole house filter system with water softener and wonder if you could explain how difficult it is to install the system ourselves? Thank you!

    1. Hi Liz

      It’s a little complicated to explain. Your best bet is to watch a whole house filter installation video on YouTube and see if you’re comfortable with all the steps.

      However, if you don’t have much confidence in your plumbing skills then I would highly recommend you get a professional.

      This is because things tend to seem simple in installation videos but they are not usually that straightforward in real life when it comes to plumbing (in my experience).

      I know for a fact that Aquasana will happily recommend a local plumber to you after you’ve made a puchase from them.

      Stay hydrated,
