When does $1 = $10, $20, or even more? In the past I made the enormous mistake of buying a "bargain" R.O. system saving about $100 (vs. iSpring). On June 27, the cut price R.O. system failed. Specifically, the other stage, carbon block, filter housing cracked open up and spilled ~250 gallons to the center of my house. Thank goodness, we were home and our dogs could alert us for the flood. Even though flood was repaired inside an hour, and the cleanup began immediately, the damage incurred was still multiple many dollars. My $100 savings sometimes of purchasing these R.O. product is now costing me and my insurance provider much MUCH more. Had we been in vacation, this minor incident would have easily resulted in MAJOR damage (multiple thousands of dollars)!!!
Needing to switch the R.O. system, I managed to get online and began to investigate who made the most effective system available. All infomration pointed to iSpring. I ordered the RCC7 and all I can think are "WOW!" The following is just a list of major observations that differentiate iSpring from a lot of its competitors�
 iSpring wet tests each system for 6 hours just before shipping the device for your requirements. (Do you need to be the first "test" the body receives?)  Each component (including the filter housings) are NSF / FDA certified. Each bit weighs substantially more than the budget, knock-off versions. Remember, a little filter housing can be quite a Serious issue.  The filters used are off finest quality and construction. My incoming water is 750 TDS. My post softener, pre-RO water is 675 TDS. My post-RO water is 17 TDS! I am still dazzled by the final results.  I called customer support to check out the technicalities of upgrading my system for the RO-90. Employees was knowledgable, efficient, courteous, and extremely professional.  iSpring provides a referral incentive - that may provide the end-user with free filters. Referrals is how iSpring turns into a large percentage of its business. reverse osmosis system Instead of going on, I encourage each you to thoroughly investigate (because i did) all your options, and after that decide upon yourself. For me, iSpring was natural choice. I wouldn't help the corporation, I have NO ownership within the company, i have NO friends or family that really work for or have ownership in the company. I rarely write reviews, but when a business / product impresses me for this degree, I wish to share my knowledge of others.
