What Is a Chromium 6 Removing Filter - and how does it work?

water filter that removes chromium

Chromium 6-removing filters use a reverse osmosis filtration system to provide clean, pure water.

Untreated water is first pushed through a 5-micron sediment filter and carbon block. 

The sediment filter removes most large particles like dirt, rust, and sand, while the carbon block removes chemicals like chlorine and fluoride from the water.

The next part is a dense RO membrane that filters out all the chemical contaminants and total dissolved solids (TDS), leaving only clean water.

Unlike other standard water filters, reverse osmosis water filter systems have a drain for flowing out the wastewater. The pure water then reaches the storage tank, where it is ready to use.

When you turn on the faucet, the water passes through the last carbon filter to ensure clean, odor-free, and contaminant-free water.

What to look for in a Chromium 6 Water Filter

Effective removal of Chromium 6 from water is crucial.

Features that make for an ideal water filter for removing Chromium 6 include:

Size & Placement

An under-sink water filter is a suitable choice for smaller spaces and apartments. It doesn’t take space on the kitchen counter and doesn’t ruin the kitchen’s overall aesthetic since it is installed under the sink.

 Meanwhile, a whole-house or point-of-entry filter is installed where the main water line enters your place.

A countertop water filter does not require permanent installation. It comes pre-assembled and can be placed anywhere you want.

Number of filter stages

chromium 6 water filter

Another important factor to consider is the number of filter stages a unit offers.

Each stage performs a certain function, and more stages generally mean better water purification.

Pre-filters remove large particles and dirt, post-filters remove unpleasant odor and taste from the water, and carbon blocks remove volatile compounds and chlorine.

Meanwhile, reverse osmosis membranes ensure the complete removal of unwanted particles and contaminants like chromium 6, arsenic, lead, and nitrates from the water.

Water pressure and flow rate

Sufficient water pressure is crucial for an efficient flow of water through the reverse osmosis membrane.

Since these systems are designed to run on the average city water pressure, the recommended water pressure is 60 psi. 

But, if the unit has a water pressure below 40 psi, you will have to invest in a booster pump, further driving up the cost.

Water pressure also determines the flow rate. Most efficient water filters can produce 100 gallons per day at optimum conditions.

However, you will need a water filter with a higher flow rate for a larger family or office use.

Storage tank

If you don’t want to wait for the unit to filter freshwater, get a unit with a storage tank. This allows you to get instant access to clean, purified water.

Budget-friendly

Chromium 6-removing water filters are relatively expensive than traditional water filters. However, you can still find a unit that is efficient and within your budget.

Just make sure you don’t compromise on quality for a few bucks.

Installation

Installing a filter for removing Chromium 6 might seem like a daunting task, especially for beginners. 

However, if you follow the instruction manual carefully, you can get the job done in no time. 

Here is a simple step-by-step process for installing these filters:

Limitations of Chromium 6 Water Filters

While Chromium 6 water filters have many benefits, some of their limitations include:

Waste Water

One of the major concerns of RO water filters is that they waste a great deal of water.

0.5 to 4 gallons of water is wasted for each gallon of water filtered, depending on the filter’s efficiency.

On average, these filters waste 2 gallons for every gallon of purified water they produce.

Expensive

Since they are more advanced with more filtration stages, RO water filters tend to cost more than other types of water filters.

A large household unit can cost you thousands of dollars, including installation.

Slow Process

Since RO water filters rely on household water pressure, the filtration process can take a long time. You may have to wait up to 2-4 hours to get 3 gallons of filtered water.

Cleaning and Maintenance

One thing that makes Chromium 6 removing water filters a good choice is their low maintenance.

However, you must change the filters at regular intervals to maintain their efficacy.

Depending on the usage, you should replace the pre-filters every 6-12 months. Similarly, the RO membrane generally lasts for 1.5 years.

Apart from changing the filters, it is necessary to clean the unit every 6 months. 

You should also clean the exterior and housing using soapy water and dry it properly to ensure long service life.
