Additionally, obtaining a water quality report from your local water supplier can help you understand the specific contents of your local water and decide on the necessity and type of a water filter.

Matching Filter Systems with Contaminants

Your local water quality should be a significant factor in your filtration system decision. For example, areas with hard water or high contaminant levels may require more advanced systems. If you notice a change in your water quality, such as cloudiness or unusual taste and smell, it may suggest that your current water filter isn’t capable of handling the new or increased level of contaminants.

Water filters that remove chemicals, heavy metals, and toxins not only improve the taste of water but also contribute to overall health by reducing impurities.

Considerations for Different Household Sizes

The size of your household and your water consumption also impact your choice of water filter system. For larger households or residences with multiple occupants, a Point of Entry (POE) system, or whole house water filter, can be beneficial. Installed at the main water line, it ensures that all water outlets in the home provide filtered water. The quantity of bathrooms in a home serves as an indicator for the water filter system’s size to accommodate the maximum water flow rate during times of peak usage.

On the other hand, single individuals or homes with lower water consumption can benefit from Point of Use (POU) systems, optimal for single connection points like under the sink or a single tap.

Types of Water Filter Systems: Pros and Cons

Reverse osmosis water filter system

Various types of water filter systems each have their own set of pros and cons. Reverse osmosis systems are capable of removing a broad variety of contaminants, including dissolved solids. However, these systems may lead to water wastage and often require extra storage space.

Under-sink filters offer the convenience of being compact and can be customized to target specific contaminants, but they are limited to purifying water at a single point of use and might need regular replacement filters.

Whole house purification systems ensure that filtered water is supplied across all water outlets in a household, which is beneficial for household appliances and plumbing. Nonetheless, they come with a higher initial cost and may not be as effective against contaminants such as fluoride.

Reverse Osmosis

Reverse osmosis systems are known for their efficacy in purifying water. They work by forcing water through a semipermeable membrane, trapping contaminants as small as bacteria and viruses. In fact, reverse osmosis is highly effective, removing up to 99.95% of:

These systems can remove heavy metals and chemicals while preserving beneficial minerals, which contributes to improved water taste. They also mitigate risks associated with water tanks that store water before it is distributed throughout the house, particularly in areas with water contamination from agricultural chemicals.

Moreover, using a whole-house water filtration system has several benefits:

  • It leads to healthier shower and bath water, which is better for your skin and hair.

  • It provides thorough water purification throughout your entire house.

  • However, whole house filters do not address contaminants that may be introduced from the piping inside the house.

  • This could require the use of additional point-of-use filters for drinking water.

Whole house purification systems typically have a higher upfront cost compared to point-of-use filters, and the costs can vary substantially based on the complexity and level of purification desired.

Installation and Maintenance Tips for Water Filter Systems

Essential regular maintenance and cartridge replacement are needed to ensure the optimum performance of your water filter system. It is important to stay on top of these tasks to keep your system working effectively. A professional service visit typically includes removing old filters, cleaning, flushing, sterilizing, and steam cleaning the system to ensure it runs effectively. However, the installation and maintenance procedures can vary based on whether you’re handling it yourself or hiring a professional.

DIY vs. Professional Installation

The choice between DIY and professional installation can depend on the complexity of the system. For example, complex systems, such as whole house water filters, often require professional assistance, leading to additional costs. On the other hand, under-sink filters, while effective, may require significant space under the sink and expert installation can be costly.

Considering both the cost and convenience of each option is a necessary step before finalizing your decision.

Regular Maintenance and Filter Replacement

Longevity and efficacy of your water filter system rely heavily on regular maintenance. Filtration systems differ in maintenance requirements; some systems need frequent filter replacements while others are more low-maintenance. Ideally, a water filter cartridge should be replaced every 6 to 12 months, but this can vary depending on water quality, usage, and the type of filtration system.

Keep in mind, over time, the cost of filter replacements and maintenance can accumulate, varying based on usage and filter quality. Timely identification of when a water filter cartridge needs replacement is key for maintaining water quality.

Environmental Impact of Bottled Water vs. Filtered Water

Comparing plastic bottles and water filter

While bottled water might seem like a convenient option, it comes with significant environmental costs. Here are some reasons why using water filter systems is a better choice:

  1. Plastic bottles from bottled water can take up to 450 years to biodegrade in the environment.

  2. Using water filter systems reduces the reliance on bottled water, thus minimizing plastic waste.

  3. Using water filter systems also reduces your carbon footprint.

Plastic Waste and Pollution

In the U.S., only one out of every six water bottles purchased is recycled, leading to over 2 million tons of water bottles ending up in landfills each year. Most plastic water bottles are made from virgin polyethylene terephthalate (PET), which is sourced from non-renewable fossil fuels. These plastics degrade in quality with each recycling cycle and photodegrade over periods as long as 1,000 years, releasing pollutants into the soil and water systems.

The energy consumed in producing plastic water bottles in the U.S. annually is equivalent to the amount needed to fuel about one million cars for a year. However, the bottling industry is investigating more sustainable options such as biodegradable or compostable materials and adopting practices like using QR codes on labels to convey sustainability efforts and reduce physical packaging waste.

Carbon Footprint

Beyond plastic waste, the production of bottled water also has a significant carbon footprint. Americans use over 17 million barrels of oil annually for the production of bottled water, not including the energy used for transportation. The energy consumed in the production of bottled water includes:

  • capturing, conveying, treating the water at the bottling plant

  • producing the bottles

  • the cleaning, filling, sealing, labeling, and refrigerating processes

The transport of bottled water to retailers and then to consumers adds to the carbon footprint of bottled water. Transporting water from distant locations to consumers increases the overall carbon emissions associated with bottled water.

Sustainable Solutions

So, what can we do to reduce our environmental impact? Rainwater filters are an eco-friendly option that helps to remove contaminants and reduce reliance on bottled water. Refilling reusable bottles made of durable materials at public water fountains and refill stations can significantly cut plastic waste and environmental impact associated with bottled water. By considering these water solutions, we can make a positive change for our planet.

Promoting awareness about the environmental impact of bottled water and advocating for the adoption of sustainable practices, such as using point-of-use filters and reusable bottles, can effect positive behavior change.
