The bathroom is another important consideration when planning for your personal water safety.  Showers, in particular, can cause problems if water is contaminated or heavily treated with chemicals. For example, cities commonly use chlorine to treat the water supply for bacteria and other contaminants, but this excess chlorine can be absorbed into the skin (sometimes in large quantities) when we’re showering, since most of us prefer to shower in warm water. The warmer the water, the more it opens pores, which effectively ushers chlorine (and any other water-borne contaminants that may be present in the water) right into the largest organ in our bodies —our skin.
Hot water can also cause any toxins, bacteria, or fungus in water to become airborne, turning a water-borne concern into a respiratory issue for some, especially those with already-compromised respiratory conditions like asthma.
How a Shower Water Filter Can Help?
In addition to reducing chemical exposure when you shower, shower head filters can also improve your hair’s shine and feel, as well as support healthier, softer skin by minimizing contact with chemicals and toxins. If you choose a water filter that softens water as well, you’ll also notice that you need less soap, shampoo, and conditioner to get the job done as soft water helps very little product lather up quickly — saving you money with every single shower.  
Shower head filters can be useful even — and especially — if you live in a dorm, rental home, or apartment, or somewhere that already features water filtration. Not all water filters are created equal, so unless you’ve done the research to know exactly what kind of water filter your water is passing through, it may not make much difference when it comes to your general health, hair or skin care routine. Softeners and filtration systems need to be serviced regularly to be effective, so if your landlord or property manager isn’t on top of the recommended maintenance, a shower head filter can be a great choice to ensure your shower is not only safe, but easier on your hair and skin. An extra bonus? Your shower will also be easier to clean, since shower head filters make it less likely water will leave unsightly or hard-to-remove hard water spots and residue on the shower and fixtures.

Improved Water Quality, Taste & Odor – The whole house water system is guaranteed to improve the water quality throughout the entire home by providing contaminant and odor free water. For example, if you notice sediment in your water and treat your home with a whole house sediment filter you will notice clean, clear water throughout every faucet. The whole house sediment filter can prevent dirt, sand and silt from clogging in your pipes.
Improved Life of Appliances – Whole house water filters are great in protecting your home from damages caused by various water contaminants. For example, if you are experiencing orange iron staining throughout the home, a whole house iron filter can remove these stains and protect your appliances by removing and preventing heavy scale buildup. Benefit from reduced red staining, rust particles and rotten egg odor. Improved water clarity and purity without any bad odors. 
Improved Health – Chlorine is a useful chemical used to treat tap water. Unfortunately, it is also a toxic chemical that is harmful for our skin and lungs. When we shower, the heat opens up our pores and absorbs chlorine from both the water and steam. A whole house carbon filter removes chlorine and provides chlorine-free showers, baths and face washes to all faucets in the home.
Softer Skin & Hair – A whole house water softener is extremely beneficial in reducing scale buildup throughout the entire home. This results in easier cleaning, softer hair, skin and brighter, longer lasting clothes.  More importantly, it protects pipes and appliances from scale build up to protect any clogging from occurring. Water appliances are able to maximize their efficiency because of the reduced scale buildup from hard water.
Whole house filters remove chlorine and other chemical taste/odor, iron and scale build-up, plus dirt/sediment, making water cleaner and clearer for your whole house. If you have no special contamination issues then a whole house carbon filtration system is recommended for general multi-purpose whole house purification. If you have special water problems then you would need a whole house system dedicated to treat that contaminant. A whole house softener is recommended if you require soft water for a scale free environment and spotless glassware. Whole house filters are a big investment for your home and work effectively to protect your fixtures and home appliances. Enjoy better health and peace of mind knowing harmful contaminants have been removed from every faucet outlet in your entire home.    

How does a big blue water filter housing work?
A Big Blue filter housing holds big filter cartridges. Other manufacturers don’t describe their large diameter filter housings as Big Blue. Any term for large diameter housings refers to housings that operate the same way. Water enters one end and goes down through the housing. Depending on what type of filter cartridge you have, water might flow through the filter and then out, or it might go all the way to the bottom and flow up through the media in the drop-in cartridge. You can put a variety of filter cartridges inside a housing depending on what you’re trying to filter out.
Big Blue 10″ housing
What are Big Blue filter housings used for?
These filter housings are used for point-of-entry (POE) filtration, typically residential. They can be used commercially with more flow rate than a standard-size filter housing. A lot of water can flow through a large-diameter filter housing, so it’s used for a variety of applications. You can put a sediment filter, a carbon filter, or a specialty filter with ion-exchange resin or arsenic-reducing media in a Big Blue filter housing.
What do Big Blue filter housings remove?
The housing itself doesn’t remove anything. It just directs water flow around whatever filter cartridge you put inside. The cartridge does the filtering, or separating the water from the contaminants. The filter housing itself doesn’t do anything until you put something inside. And what type of cartridge you put inside determines what will be removed.
What’s the difference between Big Blue and other filter housings?
Size. Big Blue filter housings work best with point-of-entry flow rates for a whole house. Smaller filters and filter housings are used at the point-of-use (POU). The small cartridges are designed to install under the sink to filter water to a dedicated faucet or with a combination of filters in a reverse osmosis system. Filter housings are designed differently to accommodate flow rate. If you’re looking for a point-of-entry (POE) filter, you’ll want something that can withstand high flow rate. And that’s where the Big Blue housings come into play.
How do you install a Big Blue filter housing?
The Big Blue housing cap is threaded to match plumbing size. These caps are available in three-quarter, one-inch, inch and a quarter, an inch and a half thread sizes. When you’re installing the filter and housing and you have an inch and a half plumbing, make sure the cap measure an inch and a half because you never want to reduce the size from your plumbing size.
If you have a three-quarter-inch cap and an inch and a half housing, you can reduce the fitting down to three quarter with a bushing. If you’re using your Big Blue housing commercially, just connect the water into it. The cap has an in and an out. The end is the feed side. The out is the filtered side. Make sure the in and out are lined up properly since the filter housing doesn’t come on a mounted bracket. Then install your mounting bracket on to hand the filter housing on the wall.
How often should you change a Big Blue filter housing?
Every 10 years.
Big Blue filter housings are dependable and last a long time. The manufacturer suggests that you replace it every 10 years. If the housing’s been in place for 10 years, you probably should replace it. Every time you turn a faucet off while water is flowing through this filter housing, water hammering occurs. This means the inertia of the water flow stops with a force of energy. Many times water hammering causes the housing to move or flex. Eventually, the plastic could get tired of flexing and start to crack. Housings with clear sumps (body) don’t flex like the blue ones or the white ones or the black ones. Clear filter housings use a different plastic blend that doesn’t flex as well, so it cracks and fails much sooner than the polypropylene colored ones. We recommend you change a clear filter housing at least every five years so that you don’t end up with a catastrophic failure where the housing cracks and water floods.
Which Big Blue filter housing do I need?
The Big Blue filter housing has a specific application in conjunction with the cartridge that we’re going to use with it. The filter system that’s right for you could include a combination of filter housings, like one with a sediment filter and one with a carbon filter for removing chlorine or taste and odors. The filter that’s right for you really depends on your water quality.

An under-sink water filter is a common water purification device that works to remove many different kinds of contaminants from drinking water. 
Purification device means that the system is installed where you need access to clean water, such as at your kitchen or bathroom faucet, office, RV, or anywhere you have an appliance that requires clean, filtered water. Also, under-sink water filters are in-line filters that connect directly to your waterline. 
The water passes through the filter before coming through your tap or other outlets. However, some under-sink filters dispense water through their own specially-installed faucet.The water delivery process of a conventional under-sink filter is pretty simple and straightforward. The filter gets its water via a flexible plastic tube that’s connected directly to your cold-water line under the sink. Essentially, the tube diverts some of the water to the filter.
The water then leaves the filter through a separate flexible plastic tube and is delivered to you through the filter’s own dedicated faucet, mounted on top of the sink. That means there’s no mixing with unfiltered water.
Because of the constant pressure on the system, the water flows from the filter and out the tap when you turn on the dedicated faucet. Only drinking water delivered via the special faucet is filtered. The sink’s regular cold and hot water functions remain independent.
In contrast, simple under-sink filters have a slightly different water delivery system. In this arrangement, all of the water is diverted through the filter, and the filtered water is dispensed only through the regular cold-water sink faucet.

Activated carbon water filters are one of the most commonly used water purification products, and their low cost and effectiveness have become their irreplaceable advantages. Generally speaking, compressed activated carbon filters and granular activated carbon filters are the two most common types.Activated carbon block filterIt is made by extruding or sintering activated carbon and binder as raw materials. The filter element has low ash powder, wide and uniform micropore distribution, and has excellent functions of adsorbing residual chlorine, odor and pigment, and removing organic compounds. The compressed activated carbon filter is used together with the water filter housing as a part of the water purification equipment.Granular activated carbon filterUsing high-quality activated carbon as raw material, it can efficiently adsorb residual chlorine, odor, color number, organic matter in the water, residual pesticides and other chemical substances. All activated carbon has been specially processed to greatly reduce the dust; meltblown pads and non-woven fabrics are placed at both ends of the filter element, so that the filter element has good efficiency, high flow, and no black water flows out.Compressed activated carbon filterIt is made by extruding or sintering activated carbon and binder as raw materials.

Tap water cannot be drunk directly, unless you install an RO system. Are you still using an 80GPD RO system with barrels? This article will recommend 600GPD high flow RO system for you, it will be a more wise choice for your family.

600GPD high flow RO system – tankless design

The traditional RO system will match a pressure bucket due to its slower flow rate; even if you do not use water, the RO system will work normally until the pressure bucket is full. There will be many problems. The existence of the barrel will take up more space under the stage that you are not big. In addition, water stored in a pressure tank will undoubtedly breed bacteria, which will bring you a hidden danger to drinking water. Our RO system uses 600GPD membrane, so you don’t have to worry about the slow water flow. It only takes a few seconds to fill a glass of water.

600GPD high flow RO system — smart design

You don’t know how to replace the filter cartridges, and the sales staff will tell you that you need to replace them regularly. Maybe 6 months, maybe 2 years. This is undoubtedly a bad thing. Our RO system will remind you to replace the filter elements if they really need to be replaced. You will see a screen on the faucet. When a red light comes on, you need to replace the water filter element immediately. In addition, the TDS value will be displayed on the screen, which will make it easy for you to find out whether your RO system is really working.
