Do NOT Buy? Aquasana Whole House Water Filter Models (COMPARED)

Article Last Updated: December 2021

This is a review of the 2 best Aquasana whole house water filter models.

You need to consider getting a whole house water filter if your tap water contains lots of hard minerals.

The main polluters that produce hard water are magnesium and calcium. When these two come together, they form hard crystals that create white limescale deposits on your sink, in your taps and even in your kettle.

Water Softener ValveA whole house filter with salt free softeners will prevent this from happening. It will do this by both filtering and reducing the effects of hard minerals. This results in filtered water that is pleasant to drink and protects your equipment.

Using “salt free softeners” that descales your pipes means that your plumbing and pipes are protected without aggressive chemicals or salt.

The result of salt-free descalers can be excellent for your water supply. Aquasana says that they have decided to go without salt on the route because the addition of sodium (salt) damages the environment in the wastewater and for the plants difficult to treat.

The two Aquasana whole house water filters are:

Both models are relatively easy to install but it’s also possible to hire a plumber if you are new to this type of device. However, you can usually get an installation kit when purchasing directly from Aquasana. Simply give this kit to your plumber and they will know what to do.


SimplySoft + Aquasana Rhino 10-year, 1,000,000 Gallon Whole House Water Filter

Aquasana Rhino, 10 or 1 million years old, offers a filtration system for the entire house for 1,000,000 liters of water. Now this device is equipped with an optional salt-free water softener, so its effectively a filter and softener combination.

Aquasana Rhino has an exclusive double flow design. This design increases its contact time with water. The result is greater retention and it prevents filter media from blocking.Aquasana Whole House Features List

This can also result in cleaner and healthier air, since chlorine and volatile organic chemicals (VOC’s) can pollute the air. Especially as the Aquasana Rhino eliminates 97% chlorine.

This Aquasana whole house water filter reduces other harmful contaminants, including:

  • Heavy metals such as mercury.
  • Industrial solvents.
  • Organic chemicals, such as pesticides, herbicides and volatile organic compounds (VOC’s).

All this means that the use of Aquasana Rhino can help reduce or eliminate the contact of your body with aggressive chlorine and other synthetic chemicals. This is especially useful for those who are usually affected by dry hair and skin.

While there is also an optional salt-free softener upgrade that you can get, which will give you a water descaler option that works without salt:

Salt Free Softener + OptimH2O + Sterilight UV Filter Whole House Filter Review

Aquasana SimplySoft is an independent stand alone water softening descaler that protects water equipment and reduces the effects of hard water. It also facilitates the reduction of the adverse effects of corrosion and dirt. This includes the effects of hard minerals such as barium, magnesium and calcium.

Aquasana SimplySoftGetting a water conditioner in the form of the Aquasana SimplySoft machine will extend the life of your water equipment.

It can even help reduce existing limescale accumulation while prolonging the useful life of expensive kitchen and bathroom equipment.

The bottom line is that although technically it does not produce soft water because it does not use salt, it can help reduce the effects of hard minerals in the water.

This will prevent stains or a white film residue on your glassware. This also includes the protection of dishes and clothing.

You can easily use and add the SimplySoft (or the equivalent add called “Salt-Free Water Softener”) unit in any OptimH2O or Aquasana EQ Rhino to make it also filter water in your home. The OptimH2O is one of the few whole house filters that is powerful enough to deal with heavy metals like lead.

  1. I’ve been in my house for 40 years and have used a salt and iron filter system. Nothing but hassles. Looking for a system that will also rid the iron in the water. Which one of your systems would you recommend. I like that you also have the ultraviolet.

  2. What about a great unit for the whole house that gets rid of chlorine and fluoride too. I’m building a new home and have thyroid issues. I’m using a counter top AquaTru which I love but want a whole house system for the new place. Thanks

  3. Mr. Water Geek – you know your stuff! Thank you – but I am confused. Your headline here says Do not buy? And I don’t see anything in your review that explains why? I am comparing Aquasana vs. Kinetico – Which should I buy for whole house water softening and drinking water improvement? If I want the best do I buy Kinetico(which one?) and if I want the best value do I use your discount and buy Aquasana? Help!

    1. Hi Chris

      It really depends on what your needs are.

      You should opt for a whole house salt based softener filter combo (e.g. this) if you have extremely hard water.

      Salt free softeners like the ones used by Aquasana are ideal for low to medium hard water (below 25 ppm) but they are more powerful at treating extremely contaminated water e.g chlorine, heavy metals like lead etc.

      You should only use my coupon if there isn’t a better offer on the site. The current site wide offer on Aquasana is for 60% so I would go with that over my 50% coupon.

      Let me know if you have any further questions.
      Stay hydrated,

      1. Thank you so much – you are a real professional with both great advise and honesty. I am putting Kinetico into my Fl house and putting Aquasana in my NJ condo. Thank You

  4. Hi Luke,

    Appreciate your knowledge and your comprehensive coverage of water industry products. We have chloramine in our water (among other things like Bromodichloromethane, TTHMs etc in water quality report) here in Manhattan Beach, CA. In your expert opinion, would the Aquasana EQ-400 or OptimH2O be best for our approx. 4000 sq ft (4.5 bath) home?

    1. Hi Wendy

      You are right to make this selection as they both effectively tackle chloramines.

      The OptimH20 is more expensive because it can also treat things like lead to a higher degree (over 99%) as well as other chemicals – which is not the case for most whole house systems.

      However, if your biggest issue is simply chlormaines (and nothing more serious) then I would say the EQ-400.

      400K gallons is a sufficient capacity for a 4.5 bath home. Also, adding the salt free conditioner and UV filter gives you extra protection and the overall price will still be cheaper than the OptimH20.

      Stay hydrated,
