How it works this Filtration System

Aquasana Water Filter Reviews

The Aquasana (paid link) is one of the few filters on the market that is capable of removing chloramines.

Many users on Amazon have reviewed that this is often the explanation they bought the system in the 1st place.

Sometimes water municipalities can use chloramines, rather than the more common chlorine, for decontaminating water.

You must visit your local water municipality to check what chemicals they use in their treatment methods.

The 3 stage filtration method that the aquasana uses is incredibly effective at removing unwanted contaminants and foreign toxins.

Stage One: During this initial stage water flows through activated charcoal, which could be quite common filtration media. Activated charcoal is helpful as a result of it’s an incredible surface area.

On their website, Aquasana states that water going through their filters runs over nearly 2 million square feet of surface area that is comparable to 35 soccer fields. That’s a giant punch for such a small package.

That large surface area allows the activated carbon to filter out a whole host of unwanted toxins and other chemicals.

Stage Two: once going through the activated charcoal, the water next goes through an ion-exchange filter.

Within this filter, water runs through a series of high surface area resin beads. There, unwanted cations (metals) are changed to harmless hydrogen or hydroxyl atoms.

This filtration stage will catch micro-pollutants that the activated charcoal filter didn’t catch.

Stage Three: during the final stage of the filtration method, water passes through a Sub-micron filter.

This filter is capable of scrubbing particles out of the water all the method right down to .35 Microns. This last filter catches any particles that created it through the first two filters.

The Sub-micron filter is very effective at catching cysts that are small, organic compounds that will cause you to sick.

The Guardia cyst could be an example, as it’s comparatively common and has found its way into water supplies before when municipal filtering verified inadequate. However, this cyst is no match for an Aquasana filter.

At anyplace from 7 to 10 microns, it’s simply captured by the Aquasana’s .35 micrometer filter.

All three of the filters utilized in this method is certified by the NSF (Public Health and Safety Organization) and ANSI (American National Standards Institute).

Both of those freelance certification agencies make sure that a product functions properly and lives up to the claims made by the manufacturer.

Together, the three filters reduce up to 97 of lead, mercury, cysts, herbicides, pesticides, and VOCs from the water.

As I mentioned earlier, the Aquasana doesn’t really remove some present minerals like Ca, Mg, and metal.

While some householders realize this to be a profit, different customers think differently.

If these minerals are in your water at high levels they will cause a bad taste and you’re getting to wish them filtered out.

So you must bear in mind that if you’ve got hard water (high Ca and metal content), the Aquasana isn’t going to be an efficient system for softening your water.
