Aquasana Countertop Drinking Water Filter

The average adult human body is 50-65% water, averaging around 57-60%. The percentage of water in infants is much higher, typically around 75-78% water, dropping to 65% by one year of age.

Body composition varies according to gender and fitness level, because fatty tissue contains less water than lean tissue...given the high levels of water content in our body, and water is something that all need and drink every single day of our lives, it's a given that good water will give us good health, function and wellbeing.

This article covers on Aquasana AQ 4000 Countertop Drinking Water Filter, a simple to install (no plumber needed), affordable (a fraction of the cost of bottled water) and produces very good quality drinking water for you, your home and your offices.

The Aquasana Countertop Drinking Water Filter is a dual-filter drinking water system, and it includes 2 filter cartridges, a  chrome faucet adapter and  instructions. 

Its exclusive dual filter system uses a combination of carbon filtration, ion exchange and sub-micron filtration to filter water, and produce truly healthy, great tasting water at the convenience of your kitchen tap. With a button.

I love this because I drink water all the time, and because I'm busy taking care of the physiotherapy business and other commitments, the Aquasana AQ 4000 makes it so convenient and affordable to have safe and high quality water.

We no longer have to boil water and wait for the water to cool down, or drink direct from tap with all the contaminants in them (ugh).

  • Top Brand Comparison Chart
  • Aquasana is the number #1 rated home water filtration system in America, works better & costs less than any other brand

    The patented Aquasana AQ 4000 twin cartridge countertop drinking water filter literally installs in seconds to standard kitchen faucets and provides up to 2 litres per minute of ultra-filtered high quality water for drinking.

    I cook, and I recommend you cook also with filtered water (think of soups, rice, porridges, oatmeal), imagine how much healthier and safer your foods will be because of the water you use for yourself and family.

    If you have pets, their health will thank you for it too.

    Includes filter housing‚ chrome faucet diverter‚ twin filter cartridge set (lasts 6-8 months/filters 2000 litres) and easy to follow instructions.

    Replacement filters cost US$59.99 (before Water For Life Discount) every 6 months/2000 litres...that's less than 3.4¢ a litre/ $10.00 a month for a virtually unlimited supply of "healthy water".

    I recommend when you buy this countertop, sign up for the Water For Life (W4L) and get the replacements at US$ 50.99 with free shipping, it's a good deal and less hassle too as it'd send to you every six months (it's a wonderful solution for me so I don't have to keep thinking "when to change the filter" - great for the busy parents and working adults)

    Replacement of filters past the recommended period of 6-8 months will cause pre-mature diverter failure and system cracks.

    How does it work? Aquasana's Patented Filtration System

    The Aquasana’s twin cartridge, multi-stage filtration process uses a combination of the most effective filtration technologies, including mechanical filtration, absorption and ion exchange, sequentially. Like a good one-two punch by a world-class boxer.

    It's an Aquasana-patented process, and it selectively filters out very-specific contaminants while allowing the natural minerals to remain, creating high quality, healthy, and best tasting water possible.

    The "A" cartridge filters out sediment and turbidity first; tiny microscopic particles that can cause cloudiness and unpleasant taste and odor in water. It also filters out chlorine, the most concentrated and the most competitive chemical in our water.

    This allows the following stages in cartridge "B" to focus on the more difficult contaminants like lead and synthetic chemicals.

    The "B" cartridge is where the final stages of filtration take place. Lead is filtered out by a complex ion exchange process where lead ions are replaced with potassium ions. The process is highly effective and also enhances the natural mineral balance of water. Potassium is one of the minerals that gives water a natural spring water taste and a neutral pH.

    Next is the most challenging and possibly the most important stage, the adsorption of synthetic chemicals, like herbicides, pesticides and industrial solvents.

    The "B" cartridge is also a 0.5 micron mechanical filter effective for chlorine resistant microscopic organisms like cryptosporidium and giardia, two common water borne parasites that can cause flu like symptoms for most, but can also be fatal to small children and the elderly.
