Order 3 years of RO replacment filters and maintenance kit and enjoy big discount with this value pack. 

For Model:  AR104H

Package includes: three sets of sediment and carbon filters, three bags of DI resin refill, one TFC150 membrane, and one MK300 maintenance kit.  

1st stage:  high capacity, multi-layer 5 micron sediment filter, to remove sediment, rust, sand, (replace every 6-12 months)

2nd stage:  high capacity carbon filter, carbon block, coconut shell activated carbon removes chlorine, taste & odor (replace every 12 months)  * We have modified the filter from granular to carbon block for higher performance.

3rd stage:  HTFC-150, (1:1 ratio) Special High Efficiency TFC type RO membrane filter

* Capacity:  100 GPD gallons per day at 60 psi input pressure.  120GPD at 80 psi, 150 GPD at 100 psi.

* This is a high efficiency 1 to 1 ratio RO membrane.  The production rate is about 260 to 300 mL per minute and the drain rate using 300 mL/min flow restrictor is about 280 to 320 mL/min depending on input pressure.  Therefore the product to drain ratio is approximately 1 to 1 (versus a conventional, typical RO membrane the product to drain ratio is 1:3 to 1:4)
