How often are Reverse Osmosis Filters cartridges to be changed?

Filter cartridges should be changed between 6 months to once a year depending on water quality in order to keep the TDS readings down (Total Dissolved Solids)

Why should I install filters?

Most municipal water systems are chlorinated to kill bacteria and viruses. 
However, the chlorine can form carcinogenic compounds, such as trihalomethanes and chloroform.  Also, this water still has to travel through miles of pipes before it enters your home.  The pipes are usually not clean and contain heavy metals from solder joints, fixtures, etc. The only way to ensure that your drinking water is free of contaminants is to filter it yourself in your home or office.

What are TDS readings?

TDS readings are the measurements used to determine the total dissolved solids that are in a drinking water sample. The lower the readings the fewer particles in the water the purer the water is.

How can I test my reverse osmosis drinking water to make sure it’s working?

Two easiest methods of checking the quality of your reverse osmosis are:

• Bring a water sample to our Aquapura water depot home improvement treatment store
• A TDS (Total Dissolve Solids) meter can be purchased so you can perform your own test to assure that your reverse osmosis filters are still filtering properly.
