Easy Points on Types of Water Filters

There are many types of water filters available nowadays, but it is rather difficult to understand each water filter’s nature and how they actually works! Here are some easy pointers to tell you about the differences of water filter!

38d

Type: Activated Carbon

Pros & Cons:

  • The unique adsorption properties of carbon material can be used to remove impurities in water, also remove unpleasant odor and chlorine.
  • Cannot soften water quality and filter organic chemicals, bacteria

Most suitable for:
Areas where water quality is acceptable, or has little pollution

Cautious point:
Easily breeds bacteria, hence its filters need to have ground cleaning frequently. Filter heart is recommended to be replaced every 3 to 6 months. Filter water bottle is recommended to be replaced every 1 ~ 2 months.

Type: Sodium Ion Resin Exchange

Pros & Cons:

  • Using the nature of ion exchange process, to filter excessive calcium, magnesium and other minerals contained in water.
  • However it cannot remove bacteria

Most suitable for:
Areas where water hardness is too high,

Cautious point:
Due to the ion exchange process, there are high levels of sodium ions in water, which is strongly not recommended for household who have members with cardiac issues.

reverse-osmosis-filtration

Type: Reverse Osmosis

Pros & Cons:

  • The semi-permeable membrane is excellent and efficient to remove microorganisms, viruses and bacteria.
  • However the elimination of minerals may cause lack of micronutrients for us to consume daily

Most suitable for:
Areas where water quality is hard or the water metal ion content is too high, areas that have serious water pollution.

Cautious point:
Front filter heart needs to be changed every 3 to 6 months, while the secondary filter needs to be changed every 6 to 8 months, and for the membrane tube needs to be cleaned every three years.

Type: Hollow Fiber Membrane

Pros & Cons:

  • It’s a very fine multi-layer silk membrane filter which can remove particulate impurities such as bacteria and ions.
  • However it cannot remove heavy metals contained in water.

Most suitable for:
General areas that are not polluted. It is not applicable to heavy metal contaminated areas.

Cautious point:
Because of its susceptible to chlorine corrosion filter, it is best to use by combining of activated carbon filter. Filter is recommended to change every six to eight months.

Type: Electrolysis

Pros & Cons:

  • Can only be used to separate acidic water and alkali water, hence have no filtering function and must be used with activated carbon to have filter purposes.
  • Acidic water is more commonly recommended to be used for washing and showering, as it is suggested to have beautifying function.
  • Alkali water is more commonly recommended to be used as drinking water, as it can help balancing our body’s pH value, however it is advisable to drink with caution as pH value that are too high may not be suitable for daily consume, especially for infants.
  • During its process it may produce 50% wasted water that ought to be poured, thus has low efficiency and needs to be charged 24 hours in order to work.

tap

Type: Ozonation

Pro & Cons:

  • Can be used to remove odor, colour and kill bacteria through ozonation
  • However the efficiency would be affected by external factors such as water temperature, concentration of ozone and time of ozone contact with the water.
  • Has low efficiency in filtering organic or non-organic pollutants.
  • Can produce peroxide substance that are harmful and toxic to our body.

How Safe is Our Water?

The earth is pretty much covered by water with only less than a third is taken up by land. Back to 100 years ago, or perhaps centuries ago where the Industry Revolution had yet occurred, the Earth was healthy with its clean air, clear water and full of greens. However, as the Earth’s population continues to grow and advanced, being more civillised does not mean we are treating our environment well. More than often, we take the environment for granted and had caused severe pollution the the Earth. Due to greed and inconsideration of humans, pollution has only ever gone worse and had only came to our attention after it had became a serious issue for our future, where the Earth have starting to show signs how human had exceeded the nature’s limits.

So you may ask ‘How serious is the problem?’

According to the environmental campaign organization WWF: “Pollution from toxic chemicals threatens life on this planet. Every ocean and every continent, from the tropics to the once-pristine polar regions, is contaminated.” Hence, it is a dead serious issue where it can threaten the entire ecosystem if we let the issue drag on and make no changes in our lifestyle.

There are many pollutants that can be found in water nowadays, and be it for the purpose of using or drinking, these pollutants are not safe for any living beings. However, most of the water filters by Cuckoo can eliminate these problems.

Alt_Plastics in our oceansentering the food chain
Plastic

Pollution Cause:
Industrial wastage from fishing (plastic fishing lines), littering from visitors to beach areas (plastic bottles and plastic wares),

Possible effect on health / environment:
It is not as toxic as other chemical pollutants, however can cause a major hazard to the marine creatures, and bring back the plastic into our digestion system throughout the food chain process while consuming marine products.

toothpaste microbeads

Micro Plastic Beads 

Pollution Cause:
They are often found in most facial cleansing products and body shower products, where the beads are designed to be so small and insoluble in water, we end up flush them away through water and released to the sea after the water process, which can prevent us from having clean and drinkable water, also harms the ecosystem.

Possible effect on health / environment:
Can affect our digestion system by clogging and cause malnutrition in marine creatures.

Methyl-tertiary-butyl-ether-MTBE-Plastic-can-5Litres-600x600

MTBE ( Methyl tert-butyl ether)

Pollution Cause:
It is a chemical substance contained in unleaded petrol, given its sparingly soluble characteristics, it shows no colour in the water. It can also lead to unpleasant taste and odor in water due to its vague reminiscent of diethyl ether. It is often caused through leakage of underground oil tanks or pipes.

Possible effect on health / environment:
Causes cancer, nausea, damages the respiratory and neural system

Chlorine

Pollution cause:
It is commonly added by water suppliers and manufacturers to kill bacteria, however overdose of chlorine can be toxic and cause unpleasant feeling while drinking the water.

Possible effect on health/ environment:
Chlorine is believed to contain a carcinogen which has been linked to seven different diseases including diabetes and birth defects.

Lead

Pollution Cause:
May be caused through where there are peel off of metal from old water pipes and water tank.

Possible effect on health / environment:
Damages the kidney and neural system, can cause mental retardation, impaired growth, coma and death if its high level of lead poisoning.

Oil

Pollution Cause:
88% of oil were spilled from routine shipping and caused by people pouring unused oil down drains on land, where only 12% of oil came from tanker accidents.

Possible effect on health / environment:
Can destroy the marine ecosystem as oil layer can block oxygen from entering water. Massive oil spill can cause intertilisation of marine creature’s eggs and also endanger their life by affecting the quality of water.

Mercury

Pollution Cause:

Industrial waste from factories, leakage of factory pipe

Possible effect on health / environment:
Can cause mercury poisoning where also leads to muscle weakness and poor coordination, skin rashes, memory problems, damage the hearing, sight and neural system.

——————————————————————————————————————

There are many other substances that can be found in the water which is not safe for living beings and the ecosystem. In order to make water drinkable, besides of using water filters to purify water source, immediate action needs to be taken to mitigate effects of pollution with strict laws and proper education.

 

How to Choose the Best Water Filter for your Household

Our earth is no longer healthy and we cannot just drink or use water directly from the pond, lakeside or the river nearby us in the wild. As the water we have now is already polluted due to industrialization and irresponsible care from humans. Water pollution can be disastrous and could cause a lot of problems to our health if we had consume them, or had contact with them. It is even worse for other countries which are underdeveloped as they clearly had no clean water for them to consume or use.

Scientifically proven, water is an essential element to maintain our health as our body is 70% made of water. Hence, to have the best quality of water without any pollutant is a vital concern for every household, as polluted water may cause a lot of health problems if they are contaminated with substance such as dirt, heavy metal (mercury, lead) which could lead to poison and other mental problems; nano-plastics that are insoluble in water which could cause digestion problems and etc. Given that our living environment now is advanced with technology and scientific knowledge, there are many inventories that are able to filter the unwanted substances in water, so that we can drink or use them safely in our lifestyle.

There are currently a variety of choices for us to choose for water filters in the market, and each brand’s water filter may seem different from each other on their functions, price and also durability. One of the famous brand on water filter is Cuckoo. Nevertheless, brand is not the main issue here. All we need to know, is the function that we really need based on our living environment and the quality of water supply, so that we can choose the most suitable water filter to cope with our environment to have the best quality so to optimized our health.

Firstly, it is important that the water filter can separate dirt from the water, as water may flow through pipes that are aged for decades or centuries, and the source of water may be from underground, or contain possible dirt while flowing from the source to our house. To have clean water, dirt is the first thing that we would not want to see in the crystal clear water.

Secondly, do take note if the water filter contains carbon filter that are specially designed to remove lead. And of course, try not to use hot water directly from the tap, as they are likely to contain higher levels of lead. It is advisable to heat them up separately if you need hot water, so to reduce the level of lead as much as possible from the tap.  This is because most of the lead in household water usually comes from the plumbing in your house, not from the local water supply. Nevertheless, a good water filter should handle this problem perfectly, so that we won’t be drinking lead-contaminated water.

Thirdly, if your living environment or water supply has its source located at a rather high density of minerals, it is advisable for you to choose water filters that uses reverse osmosis. This can filtered most of the excessive minerals contained in the water, including calcium, magnesium, sodium and etc.

Lastly, you need to check reviews of the water filter that you are going to purchase, and take note on reviews on their service quality, customer service, after-sale service, warranty and maintenance when deciding which brand to purchase. As different companies may have different policies other than functions that are suitable for your household!

 

Creating “a Civilization to Match the Scenery” in Western North America

It’s not as exciting as restoring a wetland or leading a geotour. It’s not as satisfying as bringing cattlemen, conservationists, commissioners and contractors together to work out a vision for their community. Planning doesn’t generate much adrenaline or many headlines. It does, however, lay the groundwork for all that follows. Last summer the Sonoran Institute began planning for the next five to 10 years by examining the West — its rapid growth, changing economy and much more. By June, we will have a new plan for best using our time, energy, funding, skills and passion for this land. Here’s a sneak preview.

 

Healthy Lands, Resilient Economies, Vibrant Communities

The goal is a West where civil dialogue and collaboration are hallmarks of decision making; people live in harmony with the land and wildlife; clean water and energy are assured; and vibrant communities, resilient economies and healthy lands reflect “a civilization to match the scenery,” as Western writer Wallace Stegner envisioned. The Sonoran Institute, with the support of people who care about the West, is working to bring this vision to reality.

Changes & Challenges:

A Snapshot Grizzlies. Saguaros. Iconic landscapes — Grand Canyon, Rocky Mountains, Yellowstone. The West is mythical — a land where many aspire to travel or live, whether in a modern city flanked by rugged wilderness or in a mountain town with world-class skiing or fishing five minutes from work. But profound change is underway. We must be careful stewards of nature’s gifts or risk losing them.

  • Growth. Arizona, Nevada, Idaho, Colorado and Utah are the fastest-growing states. Ranches and open space are giving way to subdivisions. Homes and jobs are often far apart, and streets are gridlocked. Many rural communities outgrow their small-town character. Retirees also look south of the border for affordable, resort-style living. Sources of energy and water are strained.
  • Public Land. Nearly half of the West is public land. Neighboring private development hampers wildlife migration. More off-road motorized vehicles damage resources that understaffed agencies cannot protect. Policies impede public-land managers’ work with private landowners, tribes and other jurisdictions, yet most threats arise outside public-land boundaries.
  • Laws & Policies. State and federal policies offer few incentives and limited authority for communities to plan for growth and protect their land, air and water. Poorly planned development decreases property values and increases costs of infrastructure and services.
  • Energy. Parts of the West are in the grip of an energy boom. When bust follows boom, communities have to pick up the pieces. Many are unprepared for the impacts on their land, water and social fabric.
  • Drought. Compounding these challenges, a prolonged drought is evidenced by reduced mountain snow pack, falling river levels, intense wildfires and expanding noxious weeds.
  • Changing Economy. Traditional industries no longer make a major contribution. Scenery, recreation and open space are the West’s new competitive advantage.

The challenges loom large, but they can be overcome. We can make better decisions about how to develop our communities and preserve the places and quality of life we cherish.

Community “Energized” After Institute Visit

This e-mail arrived after the Sonoran Institute’s Marjo Curgus visited Greenough, Montana, in February to help residents create a vision for their community.

Thank you, Sonoran Institute!! A quick note to thank you so much for sending Marjo to Greenough this past Saturday! Our little community (about 160) is spread out over 120 square miles around the confluence of the Blackfoot and Clearwater rivers in Missoula County and, as you can imagine, represents a wide range of personalities/wealth/nonwealth/ideas/experiences. She allowed for us to finally come together for some much-needed, constructive dialog.

I can’t tell you how much animosity and distrust she cut through – for almost six weeks prior there were people who were vehemently opposed to the Sonoran Institute facilitating in Greenough (just some wacko-enviro group to tell me what I should do with my land), but when Marjo left I got a phone call from a previous naysayer gushing, asking how soon Sonoran could be back.

I sound like a damn commercial, but the community vision day was a huge success. Also, I can’t say enough about Marjo’s energy and vitality – her toughness and humor were perfect for this crowd.

The community feels energized and excited; thank you for providing us with this opportunity. We’re looking forward to learning how Sonoran can be more involved in our future. This is a special time in Missoula County – I feel like we’re on the verge of accomplishing something great.

“Poorly planned growth” motivates donor’s action

Tim Crawford has seen a lot of change in the 30-plus years he has lived in the Rocky Mountain West, and he is not sanguine about all of it. “I’ve seen the ravages of poorly planned growth in Utah, Idaho and Montana. I feel it chases me wherever I go.”

Living in Gallatin County, Montana, for more than 20 years, Tim has been doing his part to protect agricultural open space and the recreational values he cherishes. He has placed significant acreage under conservation easement and has been a dedicated philanthropist in the conservation community.

Tim supports the Sonoran Institute and its community based approach to helping communities grow in a way that protects quality of life, nature and culture. “The Institute is realistic about growth and wants to see it done right… to ensure that growth leaves recreational and renewable resources for the future,” he says.

While discouraged about the failure of streamside setback legislation in the Montana Legislature this session, Tim feels confident that the Institute’s work can help mitigate the impacts of unfettered development along Montana’s fabled waterways.

Tim Crawford Enterprises is a diverse business that includes a downtown building, several ranches, and commercial photography. Tim’s signature landscape photos are featured in environmental publications across the region, including the Institute’s. His passions include bird and deer hunting.

Tim believes “it is a privilege to be able to give to the community.” The Sonoran Institute is privileged to count him as a loyal supporter.
