Better than advertised
I use this filter and the deionizer add-on. I get 0 water at 6.7ph with roughly 1.15:1 wastewater ratio. About 1.5 gals an hour at 80PSI. Better than advertised and @. $0.006 a gallon including waste. I am very, very happy with this setup. I have hard Rocky Mountain spring water coming out the tap. Established plants love it. Good for people too. Edibles and baby plant not so much. So I need to covert about 20 Gal a week for house and garden. This little filter is perfect.
Works great
I bought this for my Juice Plus Tower Garden. It works great. Installation was easy with sharkbites and PEX. Output is pretty slow but not really an issue for me. PPM went from 300-400 to 0-2. Plants love it.
I have had this for 2 months now it has worked great for me, has a good fill time, ph is good and the price is good as well.
A great option for smaller scale RO needs
I've had this unit for around a couple months now, and I'm very pleased. The only other RO units I could find for this price were 'no name' or 'off brand' units that had sketchy reviews at best. I was comfortable making this purchase because HL is a pretty big name in the industry and I have heard great things about their units. Now that I own one myself, I see why they come so highly recommended. Be aware that if your water source is under 40 psi that you may need a booster pump to get the 75gpd thats advertised. My water source pressure goes from 35-45 psi and I'm happy with the results, even at the lower pressure I only get 9 or 10 ppm when I started at something like 330
