4 Common Myths about RO Water 

In a world where clean and safe drinking water is necessary, reverse osmosis (RO) filtration systems have become famous for many conscious people. However, several myths and misconceptions surround RO water, leading to confusion about its benefits and drawbacks.

RO Water is Unhealthy to Drink

Some people believe RO water is terrible for your health because it lacks minerals. This is not true. Water alone doesn’t provide enough minerals for your body. Getting minerals from a balanced diet, not water would be best. RO water is safe and clean to drink.

Tap Water is Just as Good

While tap water is treated, it may still contain contaminants like lead. RO systems remove these contaminants, making your water safer and better-tasting.

RO Filters are Expensive

RO systems may seem costly upfront, but they’re cheaper in the long run than buying bottled water. Once installed, they require minimal maintenance, while bottled water expenses add up over time.

RO Systems are Wasteful

RO systems use some water to carry away contaminants, but it’s not wasted. It’s similar to using water when you shower or wash dishes. RO systems have become more efficient, and their water usage is justified for clean drinking water.

How Does RO Water System Save Your Money?

This financial example will explore the significant savings you can enjoy by picking a reverse osmosis (RO) water system instead of regularly buying bottled water. We’ll show you how you can be a winner when it comes to saving money and being kind to the environment simultaneously in a way that’s easy to understand for everyone.

Cost of RO System Installation: Let’s say you invest $300 in purchasing and installing a home RO system.

Annual Filter Replacement Cost: RO systems typically require filter replacement once a year. Replacement filters can cost around $50 per year.

Cost of Bottled Water: The average cost of a standard 16.9 oz (500 ml) bottle of water is about $1. If a person drinks 3 bottles of water per day, it would cost approximately $1,095 per year.

Now, let’s compare the costs over a span of 5 years:

• RO System Cost: $300 (initial installation) + ($50 x 5 years for filter replacements) = $550
• Bottled Water Cost: $1,095 x 5 years = $5,475

By using a reverse osmosis system, you save:

$5,475 (Cost of Bottled Water) – $550 (Cost of RO System) = $4,925

Over a 5-year period, using an RO system can save you approximately $4,925 compared to buying bottled water. This calculation demonstrates the cost-effectiveness of RO systems in the long run while reducing plastic waste.

Storage

Ensure you have sufficient space in the cupboard under your sink to accommodate the system. Remember that these systems can be quite space-intensive, so you might need to clear out some room, perhaps even removing your waste bin.

Water Pressure

It’s essential to check the water pressure in your home. Most reverse osmosis systems require a minimum pressure of 40 PSI to operate effectively. If your water pressure is lower, you might need to consider installing a booster pump to increase it. Some RO systems come with a built-in pump, while others do not.

Water Use

One significant concern with reverse osmosis systems is the substantial amount of water they generate as wastewater. The water that carries contaminants and impurities into the drain is often far greater in volume than the purified water. This is a crucial factor to consider, especially if you are in a situation where you have limited options for disposing of wastewater.

Water Supply

Consider the source of your water. In urban areas, you likely receive water from a treated municipal source, while in suburban or rural regions, your water may come from a well. Understanding your water source can help you choose the right RO system for your specific needs.

Remineralization

Some reverse osmosis systems are so efficient at removing impurities that they also strip your water of essential minerals. To address this, you might want to consider a system that includes an alkaline re-mineralizer filter. This filter can reintroduce those beneficial minerals, enhancing the taste and health benefits of your water.

Replacement Filters

Like any water filtration device, regular maintenance is crucial to ensure your RO system functions at its best. Keep in mind that different filters within the system may have varying lifespans. You will need to keep a schedule for replacing them.

Faucet

Most RO systems come with an air gap faucet as part of the package. However, some vendors offer alternatives to air gaps. We recommend using an air gap faucet for your RO system, as it offers certain advantages.

Maintenance Cost (Price of Filters)

Take into account the ongoing expenses related to replacing filters. Some systems may have more complex maintenance requirements than others, potentially affecting your long-term costs.

Water Quality (Lower TDS)

Aim for a reverse osmosis system that produces water with a lower Total Dissolved Solids (TDS) value. Lower TDS indicates better water quality and may be a critical factor for you.
