Cost: MXN $300 pesos
Processing time: 24 hours
Description: This test is for people with RO systems who want to make sure their system is working efficiently.  While this test does not give results on specific contaminants (i.e. arsenic and fluoride), it does show overall system efficiency (i.e. % of removal of all dissolved ions).  This is more than sufficient to know if your system is working correctly.

Collect Your Samples

Please note that we require two separate samples to run this test. 

  1. Fill out and submit the form below. 
  2.  Get TWO empty containers with at least 100mL capacity. A normal plastic water bottle (Ciel or any brand) will do great.  The container does not need to be new.  Plastic or glass is preferred. 
  3. Collect the first sample from your NORMAL tap (i.e. not passing through your RO system).  Rinse the bottle 3 times with the tap water.  Then fill the bottle with the TAP water and cap the bottle. 
  4. Collect the second sample from your RO tap (i.e. water that has been treated by your RO system).  Rinse the bottle three times with the RO sample water.  Then fill the bottle with the RO sample and cap the bottle. 
  5. Clearly label each sample with permanent ink (i.e. Sample #1: Non-filtered, and Sample #2: Post RO treatment).
