Product Description

RO System
RO Inside

How often do I need to replace the filters in my RO system?

It is recommended to replace Stage 1 Sediment, Stage 2 Carbon filters every 6-12 months and Stage 3 RO Membrane and Stage 4 Post Carbon filters every 18-24 months, depending on usage and water quality.

What is the ideal water pressure for this RO system?

The ideal water pressure for our RO system is between 40-75 psi. If the water pressure is too low, the system may not function properly, and if it's too high, it could damage the system.

How much water does the RO tank hold and how long does it take to fill?

Aquasure’s Premier Reverse Osmosis tanks have a capacity of 3 gallons. The time it takes to fill the tank will also depend on the size of the tank and the water pressure in your home. It takes about 1 hour to fill the tank.

What contaminants does the RO system remove from the water?

Aquasure’s RO system is designed to remove over 1000+ of harmful water contaminants such as total dissolved solids (TDS), chemicals, bacteria, viruses, lead, arsenic, fluoride, chlorine, and other impurities commonly found in water.

What are the benefits of having an RO system with a tank?

An RO system with a tank provides the reliability and convenience of having purified water readily available whenever you need it, ensuring a continuous supply of clean water without waiting for the system to purify the water each time you need it.

Well designed . Before TDS=185. After = 12
Overall happy. I like that it only puts 1.5 gallons of water down the drain for each gallon of RO water. Best I could find. The unit I purchased had most of connections already made versus the on line video. However as my sink cabinet is extra large I had to purchase extra pex line. The faucet body was well built but the top was plastic. It has a quick change feature to change the top part when it breaks. In any event I purchased a non OEM fully SS faucet and worked fine as did not want to deal with the top part of faucet. Also this did not come with a quick change water line connector for the faucet or a splitter for my ice maker.It does come with everything to make it work however. Really a easy install especially since all connections are made for you on unit. It did arrive in a crushed box so shipping could have been better.
