Stage 1 & 2
DUAL FUNCTION PRE-FILTER

Reduces suspended and particulate matter from incoming tap water down to 1 micron. Also reduces chlorine/chloramines taste and odor before passing through the RO membrane.
REVERSE OSMOSIS MEMBRANE
Semi-permeable membrane targets and reduces 13 contaminants, including fluoride, nitrates, nitrites, lead, radium and arsenic. Also reduces remaining suspended solids and dissolved solids from the water molecules. Then, these separated impurities are washed down the drain.
PROLONGED CONTACT FILTER

H3500 Water Filter - FAQ

What does “Reverse Osmosis” mean?
Reverse Osmosis (RO) is a filtration process that removes contaminants from water at the molecular level. By using pressure to squeeze your water against a special membrane, water molecules are separated from impurities. Rejected dissolved solids are automatically rinsed down the drain leaving only high-quality water for you to use.
What can it remove from my water?
The H3500 Reverse Osmosis Filter removes chlorine, sediment and other particles to provide high quality drinking water.
Is the H3500 Filter certified for contaminant removal?
The H3500 is certified to reduce fluoride, lead, arsenic, nitrates/nitrites and eight other contaminants.
Can you test my water for me?
Yes! The best way to know what kind of water filtration you need is to perform a test to see the contaminants you are dealing with. We want to make sure all of our customers are consuming clean and pure water. Contact a dealer today to get your water tested!
What does the 25-year warranty cover?
Hague Quality Water International warrants that upon receipt from the owner of any Hague RO dispensing spigot, filter housing and cap, PCF filter housing and cap, membrane housing and cap, found to be defective in material or workmanship, Hague will repair or replace the defective item, at no charge for that item, for 25 YEARS from date of installation. Read the full warranty.
How many gallons can it filter per day?
The H3500 can filter up to 50 gallons per day. A storage tank included with the system will store up to 3 gallons at a time to ensure that you have freshly filtered water on demand.
How often will I need to replace the filter cartridges?
The carbon filters should be changed every six months, and the RO membrane cartridge should be changed every 12 months. If you have high levels of contaminants in your water, you may need to change your filters more frequently.
Why does the H3500 have a pump included?
Hague Water’s complete system includes our non-electric pump, which fills the tank five times faster than conventional RO systems and does not require an external power supply.
Does the H3500 come with a faucet?
Yes, our complete system includes a faucet.
