Benefits of Water Filters

If you’re travelling it’s always been a good idea to not drink the local water, just in case.  These days even tap water in countries where it is designated safe to drink like in the UK, there is a lot of sceptesism. Probably rightfully so. 

One of the primary advantages is the removal of harmful contaminants such as chlorine, lead, mercury, and other heavy metals that can pose serious health risks. By filtering out these impurities, water filters provide safer and cleaner drinking water, which is essential for maintaining good health. Additionally, many water filters are effective in eliminating bacteria and parasites, which can prevent waterborne illnesses and ensure that the water is safe for consumption. This is particularly important in areas where water quality is questionable or where there are concerns about the safety of tap water.

Another notable benefit of is the improvement in the taste and odor of drinking water. Chlorine, which is commonly used in municipal water treatment, can leave an unpleasant taste and smell in tap water. Water filters can remove chlorine and other chemicals, resulting in water that tastes fresher and more pleasant. This can encourage increased water consumption, which is beneficial for overall health and hydration. Furthermore, using water filters can be environmentally friendly and cost-effective in the long run, as it reduces the need for bottled water, thereby decreasing plastic waste and saving money. Overall, water filters contribute to better health, improved water quality, and environmental sustainability.

Types of Filters

Travel Water Filters

Pros: Travel water filters are designed for portability and convenience. They are excellent for outdoor activities like hiking, camping, and international travel where access to clean water might be limited. These filters can remove bacteria, parasites, and other harmful microorganisms, making natural water sources safe to drink.

Cons: While travel water filters are effective for microbial contamination, they often do not filter out chemicals, heavy metals, or viruses. Their small size limits the amount of water that can be filtered at once, which might not be practical for large groups or long-term use. Additionally, some models require regular cleaning to maintain their effectiveness.

Water Jug Filters

Pros: Water jug filters are convenient and easy to use. They are designed for everyday use and fit easily in most refrigerators. These filters are effective at removing chlorine, lead, and some other contaminants, improving the taste and odor of tap water. They are also relatively affordable and readily available in stores and online.

Cons: The main downside is their limited filtering capacity. They need frequent replacement, which can add up in cost over time. Additionally, they might not effectively remove all contaminants, such as bacteria, viruses, and certain heavy metals. Therefore, while they improve the taste and reduce some contaminants, they are not suitable for filtering heavily contaminated water.

Reverse Osmosis Filters

Pros: Reverse osmosis (RO) filters are highly effective at removing a wide range of contaminants, including heavy metals, chlorine, fluoride, and other dissolved solids. They provide high-quality, clean drinking water and are often used in households for comprehensive water purification. RO systems typically include multiple stages of filtration, ensuring thorough removal of impurities.

Cons: RO filters are generally more expensive to purchase and install compared to other types of filters. They also require regular maintenance and filter replacements, which can be costly. Additionally, RO systems waste a significant amount of water—up to three gallons for every gallon of purified water produced. This inefficiency can be a concern in areas with water scarcity.

Gravity (Standing) Filters.

Pros: Gravity water filters, like those from Berkey, are versatile and can be used in various settings, including at home, during camping trips, or in emergency situations. They do not require electricity, making them useful in off-grid locations. These filters can remove bacteria, parasites, chemicals, and heavy metals, providing a comprehensive filtration solution. They also have a large capacity and can filter significant amounts of water at once.

Cons: These can be bulky and less portable compared to other filtration options like travel filters. They also require regular cleaning and maintenance to prevent clogging and ensure optimal performance. Additionally, the initial cost of purchasing a high-quality gravity filter can be relatively high, though they offer long-term value.
