We replace these filters every 6 months. They keep our drinking water pure. No more mineral buildup in the teapot and coffee maker. No more need to buy bottled water.

The best water system. We love this product. We’ve had this for 5 years now and must say the 💦 water is better than bottled water.

Glad to be able to find the Pure Blue H20 filters for our Osmosis water purifier. To find a substantial distributor you can trust, is hard to find, and also filters that are compatible with different water systems.

After long years of usage finally learned ( was nervous about changing it) through YouTube how to change filters that does above average “cleaning” H2O good for drinking and coffee. Drawback- remembering when to change filters and the 3-5 year filter this time was out of stock for a few months!

I like their water filter, but unfortunately they don’t have the blue filter that can be replaced every 2 years.
