Great price for these. There is one additional filter not included in this set but it only has to be changed out every 5 years. We easily changed these out and got the air compressor out to add air to the big tank (our water was barely coming out so we googled what the problem could be and it was that the water storage tank needed air). Now the water comes out normally and tastes great.

The Pure Blue H2O Reverse Osmosis Filter System has been a wonderful addition to our home. Clear, great tasting filtered water at just a twist of a knob is so convenient. These replacement filters are so easy to use and install, just twist off, twist on and done. This order is the second time I will be replacing these filters, one of the best purchase and addition to my home. No monthly delivery payments. No weekly or daily purchase of bottled water. Reduced our use of plastic water bottles, we can reuse any bottle we have purchased.
