How frequently should you change your filters?
It is recommended that you change the pre-filters on the ROpure5 residential RO systems once every 6-12 months, depending on the quality of your tap water. If there aren't a lot of physical particles in the tap water, you will get upwards of a year on the pre-filters. You will be able to tell when the pre-filters should be changed, by the time it takes to produce the purified water. The system will slow down significantly and you’ll notice the holding tank not filling as quickly as it was, with the RO water.
The Reverse Osmosis membrane on these systems will last up to 2 years before they need replacing.
The TFC membranes may actually last longer than 2 years, again, dependent upon the quality of the raw tap water in your home.
When the RO Membrane begins to lose its effectiveness, the water production will slow and the TDS ( total dissolved solids) could gradually start to increase in the purified water. Most water, after it is purified through an RO Membrane will have a 90-95% reduction in TDS. The easiest and most cost-effective way to monitor the efficiency of the RO Membrane with the use a TDS meter. The ROPure Systems come equipped with a built-in TDS monitor.
The 3 pre-filters filters below will fit any system with standard 10" Housings. Please check your systems' membrane to determine which one you need. |
