It is a damn good price with saving of $40 from the costco’s original price. Currently selling for $189.99 at costco.com and $249 at watts.com store. This offer is from Mar 28 – April 25, 2011.

It is a 5 stage VOC filteration system capable of filter most of the contamination and bad things in the water. It uses 3 filter and a membrane. Filters cost around $15 for 6 months and membrane which is $75 needs to change only every 2-5 years or so depending on the water quality. Installation is reasonbly easy and doesn’t take a long time if you are do-it-yourselfer.
I been using this same Watts WP-4v RO system for well over 4 years. It has always given good tasty and healthy water and saved me a lot of money and time as well. Actually I am upgrading my old system to new one by taking advantage of this offer because I need to change my membrane anyways which is around $75. So if I buy this system for $150, I get new membrane and new filters and new system for another $75 extra which can run for another 4 years or more.
Let me do some math to help you out. If you are family of 2 and uses 10 gallons of drinking water by buying 5 gallon Ozaka water pack in Costco for $4.50. You will be spending approximately $9 per week which will come out to $468/year. If you buy this system, $149+tax as one time investment and $35 for filter per year which is an on going expense of only $35, saving $400 or so. Only disadvantage on any RO filteration system is it takes 3 gallons of water to make 1 gallon of good water. So you might pay extra for the water every month. Even if you pay $10 extra on your monthly water bill and spend $75 after 2 years for membrane, you will still save a lot and more in the long run.
I strongly recommend to take advantage of this offer starting next week if you are looking for a filteration system which is less expensive and does the job right giving you good water for drinking as well cooking.
