In this article, I will compare iSpring vs. APEC vs. Aquasana.
To make it more interesting, I have decided to figure out which one of these is the best option under $200.
You know it’s simple to buy a filter if you have the budget, but it’s different when you don’t have it.
On top of that:
Why would you waste the money if there are efficient systems that would do a great job?
Below I have included detailed comparison table where you will find pretty much all the information you need to know about every filter in this article.

The truth is:
iSpring makes good filters!
So, what is so good about this particular one?
Compared to the rest of filters in this article, iSpring comes with 6-stages. I think this is a fantastic offer given the fact that we are selecting a system under $200.
Let’s be honest!
You won’t be able to find something like this for the given price.
Let’s dive deeper to see what else iSpring offers.
We know that RO systems are the ones with the best performance.
For this very reason, I think there is no need to talk extensively about the performance of this filter as the RO membrane ensures high rates anyway.
But for the peace of mind, here is the list of contaminants that are filtered out of the water. Please note that the percentage may vary based on the initial quality of water.
When it comes to the capacity iSpring is able to filter up to 75 gallons per day. Again, this may vary as factors are contributing to this such as water pressure and water quality.
Let’s talk a little bit about stages.
As said earlier the filter comes with 6 stages. First three steps are so-called pre-filters. These are taking care of chlorine and some larger sediments.
The fourth stage is the RO membrane itself and is followed by the tank storage.
The tank itself has a capacity of 3.2 gallons and is not made of fiberglass which is usually used with water softeners. Also, 0.7 gallons of the capacity is used to generate the pressure to push water to the faucet.
Mainly, there are only 2.5 gallons of water usable. The manufacturer reports that it takes up to 3 hours to fill this tank, and again it depends on water in your area.
As you have noticed tank is placed after the RO stage, but there are still two more filtration steps left, which means these are used for already filtered water stored in a tank.
The post-carbon filter is there to ensure to eliminate any odor or sediment that might have accumulated in the tank.
Here we go:
We are getting to the last remineralization stage.
As you know, on top of the harmful contaminants RO membrane also removes those minerals you want to keep such as magnesium or calcium.
The fact is RO filtration decrease the pH of water.
What remineralization stage does, is that it adds healthy minerals back to water which will improve the taste and also it will increase the pH of the water to make it alkaline.
Note that there different times for filter replacement. However, I would recommend changing all stages no longer than every 6 months and RO membrane up to 12 months.
Here is the deal with warranty:
The manufacturer offers a standard 1-year warranty and 30-day money back guarantee.
What makes this system to stand out is that you are getting 6-stages of filtration.
I am pretty sure you won’t be disappointed with iSpring if you are looking for high performing filter within the given budget to purify water for drinking and cooking.

APEC and iSpring are both great companies, and I can actually say that they are rivals in the water filtration niche.
Compared to iSpring, this filter comes with only 5 stages.
Those are the same as for iSpring, and even the treatment capacity is the same 75 GPD.
The good thing is:
If you know, you are not going to use this filter heavily, you can opt-in for cheaper version ESSENCE ROES-50 that provides 50 gallons a day.
Apart from that:
The difference is that the tank is slightly bigger compared to iSpring.
It comes with the capacity of 4 gallons, and unfortunately, there is no information about how much water is used to generate the pressure.
Although, I would assume it would be somewhere in the range of 0.7-1 gallon.
Another thing I have noticed is that manufacturer states that stages will last up to 12 months which is excellent.
Although, due to bacteria I wouldn’t recommend you to use cartridges for more than 6 months anyway.
What I like most about this company is the charity program that APEC runs.
Basically, from each purchase you make APEC take some money and provide free reverse osmosis system to people who are facing financial and medical difficulties.
For you, as for the buyer, it’s good to know that you are supporting the ones in need.
The installation itself is also simple as pointed out by many users.
What you would like, is the customer service that is very helpful and fast in response.
The warranty is 1-year, same as for the previous system.
If you want to get yourself a filter and support someone in need than APEC would be a great way to go.
Compared to iSpring it doesn’t offer remineralization, however, regarding build and quality it is an excellent unit, and you won’t be disappointed.
Aquasana OptimH2O 3-Stage
Here is the thing:
Compared to previous two filters you may argue that Aquasana is not the competition with its 3 stages.
I would ask you to hold on on this though and read this as I am pretty sure Aquasana will surprise you as well as it surprised me.
Let’s start with certifications:
There are not many units out there that can be proud holders of all NSF certificates, but Aquasana is one of them.
Let me explain a little bit what different NSF certificate mean:
Lot’s of filters are NSF certified but not so many has that many certificates.
Another certificate that Aquasana has is called P473. This is quite a new certification, and Aquasana is the first proud owner.
Okay Eugen, but what does it mean?
P473 ensures that contaminants called perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) are reduced in water.
Mostly, these are fluorinated chemicals that are commonly used in fabric and textile manufacturing and other industries.
What do you say now?
It doesn’t look like a weak competitor anymore, right?
So, certificates are covered and let’s have a quick look at those 3 stages as compared to the previous two, Aquasana has selected a slightly different approach.
As you can see previously mentioned systems have 3 pre-filtration stages followed by RO membrane.
What Aquasana did is put just one pre-treatment carbon filter before the RO membrane.
This is an interesting approach although, I believe it might slightly reduce the lifespan of the membrane.
After the RO membrane, there is a stage called Claryum filtration.
The cartridge is made of different materials and contains activated and catalytic carbon, well-known in this industry, ion-exchange resin, and sub-micron mechanical filtration.
I would say everything that is contained in pre-filtration stages of the other two filters is included in this one cartridge.
After these stages, there is also a remineralization stage to improve the pH and ad minerals back. So, there are actually 4 stages, but the manufacturer doesn’t count remineralization as the separate stage.
What you will love:
As well as other two unit Aquasana also removes fluoride. You can read my other article where I compare more filters that remove fluoride.
This system also comes with a metal tank to store water. The capacity of the tank is 3.2 gallons, and as well as other two the available capacity is lower. This depends on the initial water pressure.
The manufacturer gives 2-year warranty for the product with a 90-day guarantee, which makes it a winner in my eyes.
Something to be aware of is that users reported a bit confusing installation. So, if you don’t have experience with plumbing I would instead call the professional.
If you are looking for the certified and tested unit for the price, Aquasana will serve you well.
NSF certification assures that you won’t be scammed and the filter will perform as claimed. Note, that compared to the other two units Aquasana has a lower filtration capacity, and won’t be suitable if your estimated consumption is high.
Who Is The Winner?
As you can see from my review all of these options are great, but we need to select one.
So let’s summarise what each filter has to offer.
The iSpring comes with 6 stages with the remineralization, 75 gallons per day of the capacity and is quite easy to install.
On the other hand, APEC offers just 5 stages of filtration, but also there is a charity program, so you will feel happy after the purchase, that you have supported people in need.
I think we all had been the most surprised with Aquasana.
On first sight, the simple filter, that offers just 3 stages of filtration, surprised us with various NSF certifications.
Also, it gives you 2-years warranty which other brands don’t and has a remineralization stage.
Personally, I would go with Aquasana as it has everything I’m looking for in a budget reverse osmosis system.
Another reason why I would select this filter is that it has only three stages of filtration.
Just think about that:
If you’re looking for a budget reverse osmosis, you don’t want to spend a lot of money on cartridges so the more stages you have, the more you have to spend on the replacements.
With three stages which are less than the other two and certified performance, I’m sure the treatment is pretty much the same as for iSpring or APEC.
So, this is it for today’s article.
It’s your turn to share your experience with budget reverse osmosis filters.
