What Do I Need to Know Before Purchasing a Reverse Osmosis System?
So, you've decided to get serious about researching Reverse Osmosis Systems before making a purchase. Perfect. Here are some more things to consider:
- Do I need to buy a tap? RO systems require a separate tap for the treated water to dispense. Did you know you can upgrade your RO faucet to match the colour, finish and style of your existing kitchen sink fixtures?
- Wondering how many stages of filtration an RO system should have? RO systems typically come in 5, 6 or 7 stages of filtration. At least 5 stages is typically recommended for most applications. Our 6 stage system adds a re-mineraliser to which enriches water with elements such as calcium and magnesium. Our 7 Stage system adds a further Ionizing cartridge to this process.
- If you're on well water or an area with high levels of sediment, you may want to consider a system that has extra pre-filtration (5 stages). Our Aquafilter RO systems will provide adequate filtration for most applications, but you might want to consider an additional pre-filtration system.
- What about water hardness? Does incoming water have a hardness level above 7 grains per gallon (gpg)? Keep in mind that an RO system is not a water softener and if your water is above 7 gpg hardness, water softener pretreatment will help preserve the life of an RO system and membrane, although not required.
- Does an RO System Waste Water? Similar to how we use water to wash our dishes, clothes or vehicles, RO technology uses water to clean the RO membranes as they process water. During the filtration process, RO systems typically use more water than the filtered water it produces. But because the system shuts down once the storage tank is full, water does not continue to run down the drain. Some systems are more water efficient than others. If this is a concern, check out the APURE SENNA nero Reverse Osmosis System.
- How much water can a system produce? Expect a GPD (gallons per day) production rate of 50% to 75% of system GPD rating. While it's true that no one really uses 50+ gallons of drinking water per day, the “50 GPD rating” is the speed that an RO system makes drinking water and actually produces a gallon of water per hour (with normal water pressure of about 60 psi). Thus, a 50 GPD-rated system will provide adequate production for the common household and will not cost much more than a lower GPD-rated system.
- Would you like RO water for your ice maker? Add a refrigerator icemaker adapter kit to easily get RO water from your icemaker. You'll no longer need to buy a separate refrigerator filter.
What's our most popular RO system? The most common system purchased by customers is the Aquafilter 7 Stage Reverse Osmosis System due to great value, made in the EU, simple installation, and quick release filters for easy filter changes.
