What steps to take if the filter is reusable?

If your RO Purifier is not exposed to water at freezing point, you can just turn off the water supply to the purifier and drain all water from the tank before you leave.

When you come back from vacation, simply turn on the water supply and drain off the first tank-full of water. Once this is done, water will be fresh and ready for consumption from the 2nd fill onwards

However in case you experience freezing temperature at your home during these times then you should turn off the water supply to the system, empty the storage tank, and remove the pre-filters as well.

In such a case you need to drain all water from all the pre-filter housings. If the pre-filters are dirty, discard filters and use new filters when the RO purifier is put back into operation.

If filters are still reusable, put them in zip bags and store them in your refrigerator’s compartment which is normally meant to store vegetables but never inside the freezer

At last remove the RO membrane from its housing and store membrane filter in the sane compartment of your refrigerator within a zip bag. Care needs to be taken to drain out all water out from the membrane housing and screw all housings back onto the water purifier.

Once back home, the pre-filters need to be put back to their designated housings and care should be taken to flush out the first tank of water before the water from the RO Purifier becomes ready and safe for consumption
