To find out which filter best cleans water from rust and organic matter, I set up an experiment with 3 filters. For this, he poured into them special solutions with a high content of rust and organic matter. I am sharing the result with you.
Recently, I was approached from the Aquaphor company and offered to make an advertisement for their filter. They said that their filters purify water better than others. This is a rather loud statement, so I suggested that the filter be checked by force. Representative of the company Aquaphor was not scared and agreed to the experiment.
To test how filters purify water, I will conduct 2 experiments: I will check how they deal with organics and see how they behave with rusty water. These are the most common problems for which filters are usually bought.
As subjects, I have a replaceable module Aquaphor A5 in their fashionable shockproof jug Provence A5 and 2 other filters of well-known Russian and foreign brands. I will not disclose their names, but if you look for filters on the Internet, you will easily understand which ones I participate in the test.
It is important to remember that the tested filters are designed to work with tap water. Therefore, in the experiment, I use liquids with the maximum concentrations of pollutants that can be found in tap water, but, of course, not in such a high concentration.
First I will check how the filter removes organic contaminants from the water. To do this, I bought methylene blue solution from the pet store, which is an organic substance. I like it because it stains the solution even in very small concentrations, and this is clearly visible to the eye. So, it is immediately clear which of the filters does its job better.
Before starting the test, you must properly prepare the filters for work. To do this, after unpacking, I filled the filters with water and left for 10 minutes. Then I installed the filters in the jugs and made a preliminary spill. This is necessary to get rid of particles of coal and dust that may fall out of the filters during transportation.
By the way, cartridges AQUAPHOR A5 have a special fine mesh that protects it well from sorbent raining. Even with it, the filter should be spilled before use.
The filters are ready for use after 15 minutes. It's time to start your first experiment. To do this, I add methylene blue solution to water and pour it into filter bowls. I wonder if the filters can handle it?
I didn't expect, but all the filters did the job. However, if you look closely, you can see that the clearest water is in the Aquaphor jug. Maybe this is due to the fact that it has transparent plastic? Let's pour into equally clear glasses.
Here it is already clearly visible that the water is different, and Aquaphor purified the water better than anyone else. I wondered what the filters were made of and cut them open.
As you can see from the photo, all filters contain carbon sorbent (black crumb) and ion-exchange resin (white balls). But at Aquaphor the sorbent does not crumble, but keeps its shape.
This effect is achieved due to the Aqualen fibers in the sorbent. It is a special fiber that acts as a binder. In addition, aqualene contains silver ions, which make bacteria sleepy. For the other two filters, the sorbent does not hold its shape and does not completely fill the filter housing.
Now I'll check the filters for how they handle rusty water. Don't ask me where I got it, but I have a rust concentrate in my hands. Before starting the experiment, I put on new filters after spilling them and preparing them for work.
Now I dilute the rust concentrate in water and pour it into jugs. And here a surprise awaited me. Rusty water was filtered for a very long time. Even the Aquaphor filter took a while to rid the water of so much rust. But at the same time he coped the fastest.
The other two filters barely coped with the experiment. Their inlet filters began to clog up with rust and the water barely got inside. Finally, the water was filtered. Let's show you which filter did the best.
To do this, I pour water into identical glasses - this way it will be easier to evaluate the transparency and color of the filtered water. As you can see, the clearest water is the one filtered by Aquaphor A5. The other two filters performed worse, the rust color still remained. Now I'll open the filter housings and see what's inside.
Rust has accumulated in the upper part of the sorbent. At Aquaphor, the sorbent keeps its shape, and it is clear that rust is only on top. The rest of the filters have rust in the middle of the sorbent, even after the first spill. It's time to take stock.
I must admit, the results of the experiment surprised me. All filters coped well with water purification from organic matter and rust. But the best result was shown by the Aquaphor A5 filter.
At first, I was skeptical about the statement of Aquaphor, but after checking it became clear that the company really makes good filters, and possibly better.
