PostHeaderIcon Reverse Osmosis Whole House Water Filters – Are These 3 Lies Causing You Uncertainty?

PostDateIcon | PostAuthorIcon

Are you looking for whole house water filters? Have you had the chance to look at reverse osmosis water purification for the whole house? A multi-stage RO drinking water filter is one of the most powerful and complete means of decontaminating your family’s water supply. Unfortunately, there are many lies being told about RO filtration, especially by salesmen who do not carry these units. The following three lies are the most commonly told pieces of misinformation meant to mislead the consumer.

1. A reverse osmosis drinking water filter is ineffective against chlorine despite its high cost.

The fact is that a reverse osmosis home water filter can remove chlorine if it uses a filter membrane that is rated for that task. However, it is true that many reverse osmosis filtration systems for the home actually use cheaper polymer filters that degrade or rot in the presence of chlorine. On the other hand, that is why many multi-stage RO whole house water filtration systems add a carbon pre-filter to remove chlorine from the incoming water supply. In the end, the consumer gains a more complete protection for his drinking water while paying a lower price.

2. Reverse osmosis whole house water filters cannot purify water that has been contaminated by industrial or agricultural accidents, e.g. the case of Pavillion, Wyoming residents whose underground water supply was contaminated by oil and gas drilling .

This is a bald-faced lie. This is actually the kind of situation where home water filtration using RO shines. Multi-stage carbon whole house water filters work well and economically when you know what kind of contaminants you are facing. Unfortunately, a pure carbon water filter cannot remove inorganic chemicals on its own. It needs the help of ion exchange resins. But these resins must be specifically formulated to decontaminate a particular chemical, e.g. nitrites. The more chemicals you need to remove, the more expensive that resin becomes. But a multi-stage RO filter, on the other hand, removes everything. It does not care what is inside your water – it will remove everything, just like distillation. That is actually both its greatest strength and greatest weakness.

Which Whole House Filter System is best for lowering solids? ....?

This is a large residential location with about 10 people. I am searching for a filtration system for the whole house. tap water comes out at 320ppm, and they would like one filter to use fr everything, pool, showers, dishwasher, lawn... Are there any systems that drop the ppm through a filter without having a waste line? All i am hearing about is carbon filtration or water softening. They dont want water sofeteners.

There is a whole spectrum of water treatment systems around for treating water for a variety of contaminates. Solids, if your are not talking about dissolved solids, are a simple filter, but this is rarely any real problem. If you are talking dissolved solids, TSD, you probably need something more sophisticated. I would send a sample of the water to a lab that does the testing, Google "water testing lab" and see what their results or if it part of a municipal water system get their test results and their recommendations for treatment. Could be activated carbon, simple filter, reverse osmosis, distillation (although not for the volume you are talking) and possibly others or combinations of them. Google "home water treatment" to see what is available. Consumer Reports puts out a good stream of info on this, try your local library to gain access without subscribing.
