WP500024 Standard Annual Water Filter Replacement Kit, White, 7 Pack

If you have a Canadian 5 stage reverse osmosis system (Watts Premier brand), the specifications in the instruction booklet are based on part numbers from the US. These are the equivalent of the US parts 100017. System that we have was in the house when we bought it - 1st time changing was worth the money to pay a plumber for an hour for a training session to learn how to do it properly.

With this price, this is likely the best options that I can find. It is very easy to install, I just take off the existing one and I know which one is for which. BTW, it is probably worth to look for "change ro filter" videos on YouTube first. I found a 5 mins video and it is very helpful. In general, like this product.

These reverse osmosis replacement filters fit my Vertex Pure Water Machine from GTA Water company perfectly. The pure and clear water it produces it so refreshing.Would definitely recommend and will definitely purchase again!

previous package arrived in broken bag， and have to return it. the replacement is good and the installation is easy.make sure discard first three tank waters.

Me gusta mucho. Con estos filtros no tengo que comprar agua en botellas o garrafones. Lo he usado por años. Dejan el agua muy limpia
