APEC ULTIMATE Inline Carbon Post-filter 10 Inch, with 3/8"D Tubing Output

Works well

Be sure you order for the right size tubing you have. There is a free adapter from 3/8 to 1/4”.

On my last RO filter change, I had all the replacement filters except this one. So I went ahead and replaced all the filters that I had on hand and ordered this one from APEC. I only had to wait two days. I love that APEC will FedEx something to you in cases like this, where you need something ASAP. So during this two days, I continued to test my Water with the other 4 filters replaced. I could get it down to 90 PPM. , but no lower. As soon as this filter came in, I installed it right away. Retested my water, it was down to 36 PPM. Bottled water is about 50 PPM. So yeah, I believe it this product.

everything is good
