I don't trust LFS RO
water. They are in business to make money...nothing wrong with that, but it leads to compromising decisions in a down economy that leads you to believe you are getting good RO
water when in reality you end up with crap that may not be much better than that which comes out of your tap-- because they may not go to the necessary expense of replacing the pads when they should. I wouldn't use any RO
water without a TDS
water has become popular because it is an easy money maker on their part. They are betting that most people don't want to pony up $200 for an RO
unit and would much rather make it a part of a routine purchase. Buyer beware with this. TDS
meters can be had for $30 and gives you piece of mind that you are buying what they are advertising.
