I have used many reverse osmosis systems. This system is so far the best. These are the reasons.1. The so called side flow technology produces 1:1 waste ratio that I have never seen in any other models2. It is rated 500 GPD and it does produce close to 500 gallons a day. I evaluated it at 60 psi, 65 F degree, and 280 TDS. I collect both RO water and waste water with two 500 gallon tanks.3. It is solid and sturdy. The lightweight metal frame stands by itself. It looks it worth $1000 a piece.4. It uses standard filter cartridges that can be found everywhere at fair price.5. The electric pump is quiet, responsive and does the job. I have run it in full capacity for over 3 months and no issue whats so ever.6. The installation could not be easier with only three John Guest fittings to be connected on the same side.The only thing I dont like is the pre-filters are 10 inches long rather than 20 inches and subject to be replaced more often, although that can be supplemented by an one or two stage whole house filter. Considering its compact size, it is really a trade off.So, this is so far the best RO system I have ever used. It fills up a 5-gallon jar in a couple of minutes. What an achieving experience! It takes TDS from 280 down to 15. It works well for my large reef aquarium and indoor hydroponic system but I believe it is suitable for both home and business use. It is a fine machine that I would recommend to anyone.
