Review: It works and came shipped with no damage - This di resin filter does do what it's supposed to,this would be excellent for a person just trying to keep there vehicles looking nice,but as a auto detailing business it's to dam small.all my pre wash and wash jobs I do out side it don't matter if it's a black vehicle on 100 deg day.di resin filters do a amazing job I just think there a pain in the ass keeping up with fresh resin and water hose.i bought the 1500 drying towel from the rag company and I prefer to use it then a du resin filter
Review: Does not meet the company's promise of 0 ppm TDS - I followed the installation and usage instructions. Even went so far as to put a water pressure regulator inline and also used a water flow control so the pressure never exceeded 50 PSI and the water flow never exceeded 2 gpm. Using a TDS metering device, the incoming water was 150-155 ppm and after passing thru the dual filters the best reading was 30 ppm TDS. I tried reaching out to the company via their website and 1 week later I've not received any type of response. Before the end of this week (in the next 3 days) I will try executing a refund request thru desertcart. I did submit the refund request which was accepted. I used the return label provided and it is on the way back to the seller/manufacturer. Update - After withholding 40% of the refund for "restocking fee" I recommend you avoid this company/storefront at all costs. They claimed the reason for the refund was "customer return" and ignored the fact the product was defective and didn't/couldn't meet the promised 0 ppm TDS.

## Questions & Answers

**Q: For my water's tds of 100 ppm in, what tds ppm can i expect at the end of your stated 100 gallon capacity for the 2 stage 10x2.5?**
A: 100 ppm in should get 0 ppm out pretty easy. After the expected 100 gallon lifespan it should slowly tick up 1 to 5 ppm each time. It won’t go back to 100 ppm quick, but slowly.

**Q: How much resin does each unit hold for replacement?**
A: Each housing holds approx 16 to 20 OZ.

**Q: where do you get the resin to refill the filters ?**
A: There are multiple suppliers for this media.  Here's just one of them.  https://www.amazon.com/dp/B08BCQHNNB/?coliid=IEBSGV3O0TCCI&colid=3V0R98KKZ3FUY&psc=0&ref_=lv_ov_lig_dp_it

**Q: do you repack the filters or what is the model number of new filters?**
A: The filters can be repacked.
