Rocdu-02 Premium Undersink Reverse Osmosis Replacement Cartridge Deal

I will always sing this company's praises from the hilltops given half the chance ... had a water filter from them that must be about 15 years old now - can always get almost instant advice if I have a question (even on weekends - wt?), fast postage and good quality products. Apart from needing a couple of replacement parts over the years (minimal), our old reverse osmosis system is still chugging along! LOVE psi waterfilters!

Cartridges are good, exactly what is required and service helpful and prompt

I have been a customer for almost 17 years. Ordering replacement filters is straightforward and delivery is prompt.

The replacement filters came relatively quickly. Easy to fit but a bit tricky to keep the water from splashing everywhere. I suggest a few towels place close by when attempting this task.
Once we used it a few times the water ran clear and the water is now pristine. Well worth the effort.
Great filter.

I purchased a 5 stage RO filter system from these guys over 10 years ago with zero issues to date.
Its a very reliable business with quality parts and a deep knowledge base.
The website is easy to use for ordering replacement cartridges, and carries an extensive supply of spare parts (Haven't needed the spares parts yet)
We're very happy with our purchase.
