Here are five important reasons for all of us to ditch buying bottled water.

While tap water today may be safe to drink, it doesn't always taste great. Reverse osmosis systems can save you money and improve your health and make your water taste great

Chloramines added to water supplies provide longer disinfection in the distribution piping than chlorine. However, chloramines may cause undesirable taste and odor in water. Learn how to remove chloramine from your water here.

Your body needs clean water for lots of reasons, and most of us don’t actually consume water in a way that benefits the body as it should. Here’s the best way to consume water.

Groundwater supplies are depleting. Municipalities worry about the future viability of groundwater amid growing population numbers.

NSF is a not-for-profit corporation founded in 1944 to promote good sanitation.  Its main business is to bring together experts in public health, manufacturing, and sanitation from government, industry, academia and the public to develop and administer performance standards for products which have some impact on sanitation and public health.  NSF maintains state-of-the-art laboratories where products can be tested according to the set standards. Manufacturers voluntarily submit products for evaluation; if they pass the tests, they are “Listed” and certain tested claims are “Certified” and the products are authorized to display the NSF seal on labels and literature.  Although non-governmental, NSF does have some official status as the lead agency for the testing and approval of both the chemicals used in water treatment and the materials of construction used in drinking water systems, under contract to the U.S. Environmental Protection Agency. NSF Standards are recognized by the American National Standards Institute and the equivalent organization in the European Community, the Dutch Council for Certification (RvC).  Public Health Officials worldwide can take confidence from the knowledge that people like themselves have written and approved these standards, and NSF’s reputation for thoroughness, independence and credibility has made it one of the most trusted public agencies in the world.  NSF has also received the distinction of being appointed a Registrar for the International Standards Organization (ISO). There are two NSF Standards for “Drinking Water Treatment Units”: Standard 42 for Aesthetic Effects and Standard 53 for Health Effects. A water filter which is “NSF-Listed”, or which has claims which are “NSF Certified” is one which: Is thoughtfully designed and carefully constructed Using established water treatment media and methods Using materials of construction which are tested and documented to be appropriate for potable water use Is tested and verified to conform to minimum standards of mechanical and hydraulic strength Is tested and verified to conform to minimum standards of hydraulic functioning (minimum flow rate, maximum initial pressure drop, reasonable freedom from channeling and dumping) Is adequately and truthfully labeled and advertised Is routinely re-tested, and its manufacturing procedures, documentation and facilities inspected/audited annually Read the fine print Please note that it is important to read the small print when evaluating a products certification. There are various classes to consider, and various contaminant removals to consider. Just because a filter is certified to Std. 53 doesn’t mean it is for every one of the reductions listed below; it may only be for one or two. Make sure the reduction you require is specifically listed, i.e. Std. 53 for Cyst, turbidity, lead and asbestos reduction. Standard 53 - Health Effects (Pass / Fail criteria - no gradations or class distinction) Cyst Reduction:  99.95% reduction of particles in the 3-4 micron range Turbidity Reduction:  Over 90% reduction of 10 - 12 units of turbidity in water Lead Reduction:   Minimum 90% reduction of 150 ppb lead to 15 ppb or less, at both high and low pH levels Asbestos Reduction:  99% reduction of fibres exceeding 10 micrometers Chemical Reduction:  Usually 95% reduction of severe pollution levels to the MCL or lower, for the unit’s entire rated capacity Standard 42 - Aesthetic Effects Taste & Odor and Chlorine Reduction Class I                    - At least 75% reduction (highly effective)            Class II                   - 50 to 75% reduction (somewhat effective) Class III                  - 25 to 50% reduction (least effective) Particulate Reduction (at least 85% of particles are removed) Class I                    - 0.5 to 1 micron (SUB-MICRON) Class II                   - 1 to 5 microns (most bacteria &one-celled algae Class III                  - 5 to 15 microns (most protozoa,  pollen, silt) Class IV                  - 15 to 30 microns (FINE...mold spores, rust particles) Class V                   - 30 to 50 microns (barely visible root hairs) Class VI                  - over 50 microns (sand, leaf fragments, insect parts)   Note: Products may also be manufactured with NSF approved materials, or components, but not actually have NSF ratings for performance.  The devil is in the details so be sure to read the fine print.  

Having access to clean drinking water is important for every household. If your tap water has a foul taste or odor, you might already be buying bottled water to avoid having to drink from the tap. The cost of bottled water can quickly add up and it doesn’t address issues like cooking with your tap water. If you want to have clean water on demand, you need to find the best drinking water filter for your home. At efilters we specialize in home water filter systems that provide crisp filtered water from a dedicated tap or your existing faucet. Many homeowners are already relying on pitcher filters to supply their drinking water. These chunky pitchers may seem like an acceptable solution at first, but they have many issues that make them both inconvenient and expensive in the long run. The most obvious problem with these water filter pitchers is the constant need for maintenance. They take up valuable real estate in your fridge and they need to be filled multiple times per day. The filters they use also are only rated for about 40 gallons of water, but they will continue to allow water through after that window. This means pitcher users typically end up using filters well beyond their lifespan and gaining none of their benefits or they are replacing the filters often, adding to their costs and producing waste. The best drinking water filters are permanent fixtures attached to your existing sink. These systems are the perfect solution because they provide amazing clean water without the need to be constantly maintained. At efilters, we carry home filter systems from Everpure. We believe these systems offer the best quality water while being simple to install and maintain. The installation of your filter will vary depending on which model you decide to use. Most Everpure filters will require a dedicated faucet mount. If you don’t want to deal with adding an additional faucet to your countertop, you should consider the PBS400 model which uses you existing faucet’s cold water line. No matter which system you choose to use, you will need to to mount the filterhead beneath your sink. You simply screw the filterhead in place while being sure to leave ample room for installing the cartridges. The amazing cartridge design is the key to Everpure’s effectiveness. These metal cartridges feature layers of filtration to achieve the best results possible results. The carbon filter media has an incredible surface area for removing contaminants including those responsible for foul tastes and odors. The bacteriostatic component of the filters also prevents bacteria from multiplying within the filtration system. The pleated design of the filter’s membrane allows it to filter water effectively for months at a time, and the water pressure will begin to slow as the filter reaches the end of its lifespan. When your filter cartridge needs to be replaced, the process is about as simple as changing a lightbulb. You simply flip the shutoff valves on your filterhead and then unscrew the cartridge and wiggle it loose. Once this is complete you screw in the filter replacement,reopen the valves, and run the system for a few minutes to flush out any air. Once all the air is purged from the lines you’re done for another few months. If you’re ready to find the best drinking water filter for your home, visit efilters today. Our team is dedicated to helping homeowners find the perfect filter system to provide clean water on demand.

The standard advice from water filter experts is to change your refrigerator water filter every six months. It’s generally a good idea to follow that advice. After six months, your fridge’s water filter may not be working at maximum efficiency. Keep a close eye on your replacement indicator light to help tell you when it’s time for a replacement. Does a Filter Work? As the name implies, a refrigerator water filter’s job is to filter your water and remove any contaminants that could affect the taste and quality. The list includes germs that could cause infection if drunk, as well as sediments left in your water supply (e.g. chlorine and sediments). This gives you cleaner, healthier water that’s much safer to drink and use for cooking. There are several ways water filters can keep your water clean, including by reverse osmosis. Most water filters rely on carbon and sediment filtration to remove contaminants in the water. After installing, you may notice the smell and taste of chemicals disappear. That’s thanks to the carbon filter. The carbon acts as an adhesive, trapping contaminants in a process called adsorption. Think of a sponge full of dirty water. When you squeeze the sponge, the water is released outside. In this case, the carbon causes the sediments to adhere to the surface of the filter, keeping them out of your drinking water. What Happens When My Filter Becomes Unusable? Water filters, in general, can last for some time and provide plenty of protection. However, filters can wear out over time. How quickly that happens depends on the quality of water coming into your fridge. After a certain point, your filter will become too clogged with debris and sediments that have bonded to the carbon surface. At this point, bad tastes and odours won’t be absorbed and can pass through. The old filter can also start contributing to germ growth, making your water more unhealthy. What Are The Warning Signs? Some clues can tell you when your fridge’s water filter is due for replacement. Use these warning signs to help ensure your refrigerator gives you good drinking water quality. Keep an especially close eye out when you find more than one symptom. Some indicators may not always mean the filter’s time is up, but several are a more obvious tell. It’s been six months - After around six months, consider replacing your filters to keep your water clean and safe. Six months is the usually-recommended service life for most refrigerator filters and is a safe bet for ensuring a healthy water supply. Keep the date you installed the filter in mind to help you remember when the time comes for a replacement. Give yourself reminders for early warning before the six month period passes. Some filters come with a sticker where you can mark the date of installation. The indicator light is on - Many newer models of fridge come with indicator lights that can tell you when the filter needs replacement. This is an easy way of knowing when to get around to the chore, especially if you forget the exact date of installation. Some indicators are controlled by a timer, which turns on after six months have passed. Alternatively, your fridge can detect the filter’s actual status. This setting can be more convenient for you if you use less water. Some people use different amounts of water, and your filter may not need replacement after exactly six months. Slowed-down water dispenser - As the filter goes through its lifespan, sediments tend to build up on its surface. The contaminants it filters out of your water can clog the filter over time. This can block water flow when you use the fridge’s dispenser for water. Areas with hard water (water full of hard minerals like calcium) are particularly prone to sediment buildup. Take note of how long it takes to fill your glasses. If it’s taking too long, it might be time to invest in a new filter. Low-quality ice - When the water filter gets old, it can also affect the quality of the fridge’s other systems, like the ice maker. Having an old filter have effects on the quality and quantity of your ice. Pay attention if your ice maker always seems to be out of ice. Other clues to keep an eye out for are strange tastes and odours, and cloudy ice. Changing the filter may clear up your problems with the ice maker. A new one can keep sediments out and keep the water flowing when you need ice for drinks. Strange tastes - Taste is a good measuring stick for whether your water filter is still working. Installing a new filter can remove the flavour of sediments from the water and leave it feeling fresher. Over time, the tastes may come back. This is normal, so it isn’t a sign on its own. However, odd flavours are a sign that the filter may need replacement soon. Compare the time since installation with the taste to make your replacement more accurate. Inspect Your Filter Frequently Take the time to check your water and filter regularly to make sure it’s still working correctly. One rule of thumb is checking every time you clean your fridge. It’s a convenient time to check, as you’re performing maintenance and replacing the fridge’s contents. Check the connective tubing and filter for leaks or buildup that could compromise the water quality. Sample the water as well to check the water flow and to see if there are any particles in the water. Like other appliances, it’s necessary to change your fridge’s water filter cartridges after some time. Think of replacing your water filter like doing maintenance for a car. Every few months, parts have to be replaced to keep it working at peak efficiency. The trick is staying ahead of replacement and keeping the dates in mind. The simplest thing you can do is watch the indicator light to tell you when the filter starts to get clogged. Make some notes to help remind yourself about filter replacement ahead of time as well. Keep reminders of important dates to help gauge when it’s been six months since your last replacement. Watch out for when the water starts to taste strange, or when your ice isn’t as clear as before. Take the time to prepare everything before your six-month deadline. Getting everything ready before replacing your fridge’s filters part of your routine can make the process a smoother one. Use the time wisely, and you can get your refrigerator in working order without too much fuss.
