The HM Digital FM-2 filter monitor and volumizer is a nifty tool for keeping track of when to change out your reverse osmosis and de-ionization unit’s filters. The simple digital display can track up to five stages by both time and volume of water going through your RO or RO/DI unit and alert you when to change out that specific stage. No more guessing on how many gallons have traveled through your unit, you’ll be able to set the monitor to keep tabs on the volume rate and know when to change your filters. This will be quite handy to set out a filter-changing cycle where you may want to do more frequent changes to the sediment or pre-filters that are less expensive as well as taking the brunt of the filtration. An LED faucet indicator disc will illuminate a green, yellow or red light when the water is turned on indicating the percentage of elapsed time. Attaching the volumizer is via ¼†quick disconnect connections and will let you chose water volume in either gallons or liters. These units are priced just under $50 USD and is currently on sale for $38.99 over at Bulk Reef Supply.
