There are 300+ chemicals and pollutants in the tap water according to research from the Environmental Working Group. Among these are:
--Volatile Organic Chemicals (VOCs) --Heavy Metals --Endocrine Disrupting Chemicals --Fluoride
LifeStraw Go Water Bottle and LifeStraw Personal Filter is filtration equipment without power supply, battery or chemical substances, lightweight and portable, suitable for outdoor sports and daily life scenes, is one of the preferred equipment for outdoor travel. Reduce dust, bacterica and parasites.
Bottle Water
Filter Level: 20%
Pitcher water filters like Brita use Granulated Activated Charcoal to remove some contaminants. Since the carbon is not solid, it does not remove all toxins though these filters will improve taste. Pitcher filters will reduce chlorine, but are not effective at removing VOCs, heavy metals, endocrine disruptors or fluoride.
Pitcher Water Filters
Filter Level: 30%
Reverse Osmosis filtration uses a membrane which removes many contaminants from water.
Filter Level: 60%
Reverse Osmosis (RO)
Removes a large amount of contaminants. Many unites are stored under the sink and have a simple spigot over the counter for getting the water. Does reduce arsenic, asbestos and heavy metals. Does remove fluoride.
Wastes more water than it produces. Does not reduce VOCs or endocrine disruptors. Requires adequate water pressure to work.Takes up to an hour to filter one gallon of water and filters need to be replaced regularly.
Quality carbon block filters will remove VOCs, chemicals, pesticides, bacteria, fluoride (with filter attachment), heavy metals, nitrate, nitrites and parasites.
Solid Block Carbon Filters
Filter Level: 60%
Does require counter space and does have to be manually filled. Does not remove endocrine disruptors and there are some concerns with third party testing with some brands.
1st Stage: 5 Micron Melt-blown Polypropylene Sediment removes large and fine particles such as sand, dirt, silt, and rust particles. 2nd Stage: GAC Activated Carbon Filters: removes chlorine, odors and tastes of many organic compounds. 3rd Stage: 5 Micron Carbon Filters: Block carbon filters made of fine coconut shell carbon. Removes chlorine, tastes, odors, VOCs and other common chemicals. 4th Stage: Thin Film Membrane RO Membrane: TFC Membrane is the main component of any Reverse Osmosis unit. Provides up to 99% reduction rate of bacteria & chemicals. 5th Stage: Inline Granular Carbon Filter: Polishing filters; Stabilize the water tasting qualities and further removes any traces of bad tastes and odors. 6th Stage: Demineralization by Ionization– Removes hard water minerals through an ion exchange process. It removes sand, dirt, silt, rust, chlorine, odors , VOCs, bacteria , chemicals and more.
