Ever wondered how to weed out the bad home water filters from the good ones? Picking out a good filtration system for your home can be a tough choice because there are so many options out there competing for your attention. You can choose from reverse osmosis, distillation, and carbon filters. You have a choice between purchasing whole house filters, shower filters, sink filters, and kitchen faucet filters. There is so much to choose from and the only way to narrow your options is by learning a little bit about how water filters work.
How do water filters work? Reverse osmosis exposes water to a porous membrane under pressure. The membrane rejects certain contaminants, minerals, and a large part of the water itself. Inorganic contaminants and minerals have larger molecules than water so they are rejected by the membrane. The problem with reverse osmosis is that it doesn’t effectively remove synthetic chemicals like herbicides and pesticides. Many synthetic chemicals are molecularly smaller than water so they pass through the membrane.
Home water filters that use distillation are equally inefficient when it comes to removing some kinds of contaminants from tap water. During distillation, water passes over a heated coil and vaporizes. The steam then rises and enters a cooling chamber where it condenses back to water. Inorganic compounds like lead, potassium, and calcium is separated from the water during this process, as is bacteria. Organic chemicals vaporize at a lower temperature so they are transferred into the steam.
How do water filters work to give you healthier water? On top of removing contaminants, you have to choose a water filter that doesn’t take out the good stuff, which are the trace minerals. Reverse osmosis, along with distillation, was invented because of the need for demineralized water in the printing and photo processing industries. We need to drink mineral water in order to stay healthy. Drinking demineralized water can lead to multiple mineral deficiencies and in some cases, even cancer.
Because distillation and reverse osmosis are both ineffective at removing certain contaminants, they have to be used in conjunction with a carbon filter. It goes to show that you are actually better off just investing in a carbon filter to begin with. Of all home water filters, carbon block and carbon granular filters are the best for a 3 reasons. They are fast, inexpensive, and remove all contaminants without taking out the trace minerals. Carbon block filters can be installed as whole house systems or separately in the kitchen or shower. You can even get a sports bottle that contains its own carbon filter.
So there you have it. Carbon block and carbon granular filters will give you more for your money because they are the most efficient and least expensive. Rather than waste time and money on filtration systems that make your water less healthy and put a strain on your budget, choose carbon block or carbon granular filtration. Home water filters that use this technology with give you pure water that will lead you on the path towards better health.

I bet you are frustrated over constantly having to buy new water filters for your home. After all, you don’t want to drink the tap water straight- who knows where it has been. And, you certainly don’t want to keep paying for water filters that only last so long. Well, the good news is that there are a couple of tips to keep in mind when shopping for your new water filters. We’ll go over a few of them here.
When it comes to convenience, cost and efficiency, under counter water filters make the top of the lists. These filters provide your household with a constant supply of pure water while remaining out of sight and out of the way. They take a little more installation work than countertop filters but that little amount of work pays off quickly.
Bottled water is very expensive, but it is a booming industry that rakes in huge profits. These profits have a cost to the environment and your pocket book. One and a half million barrels of oil are consumed each your to produce those disposable plastic bottles that the water is packaged in. Most, if not all of these bottles are recyclable, but most end up pitched to the curb or end up filling the landfills. There is an alternative, though.
The best way to keep your water filtering system working properly is to change the filters as often as the manufacturer recommends. Many times, this will be after a certain number of gallons of water filtered, for instance 500 gallons or 1500 gallons. So if you use the filter frequently to filter your drinking water, you may find yourself spending a lot of money on filters. Time to find a discount supplier of these filters. They are not all the same, and if you shop around, you can find a place to buy these filters at the best possible discount. Many of these discounters will offer the best deals to returning customers, so if you go on an automatic program, you will get the best price.
