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)

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.
