If you want pure water, we got you covered!  Reverse Osmosis appliances are really quite simple to understand.  Some are cheap and some are quality. Some use standard replacement filters and others use special proprietary filters that only come from a single manufacturer.  Wise money purchases a high quality system that accepts standard replacement filters.  Your quality appliance will last a long time and you will always be able to find replacement filters with ease and at a low operating cost.  Cheap systems are just that . . . cheap, until they leak on your kitchen floor.  Then they are quite expensive! You should avoid manufacturers who sell cheap systems, and also avoid manufacturers who sell proprietary systems.  Fancy and expensive RO units have specially keyed filters that are only available from a single vendor and at a very high cost.  They may even automatically shut off water production based on time, regardless of water quality, which increases your cost to make water, and can leave you without water until a service call is scheduled.  A high-quality Standard RO like our H-Series will provide long service life, top quality, and over time, it will be the cheapest RO you can buy due to the standard filters that it accepts.  If you want to get fancy, we can pair these with plug and play UV or Alkaline Filters.
