free aquasana bottle Aquasana Consumers Digest Best Buy

Rated as the Consumers Digest Best Buy for six years in a row, the Aquasana AQ4000 counter top water filter provides superior water filtration at an affordable price.

You can install this home water filter in just a few minutes, and it provides up to 30 gallons of filtered water per hour. With an Aquasana water filter, you'll get the cleanest, healthiest water available at a fraction of the cost of bottled water.

Tap water and bottled water both contain numerous pollutants and chemicals, and many brands of bottled water are even more contaminated than tap water. Take responsibility for your family's health by filtering your water at home.

Aquasana AQ4000 Counter Top Water Filter Features

  • Removes over 100 common tap water contaminants, including lead (99%), chlorine (99%), synthetic chemicals (99%), VOCs (99%), THMs (99%), benzene (99%), alachlor (99%), lidane (99%), atrizine (97%), MTBE (93%), turbidity, and paracystic cysts that are resistant to chlorine (99.99%).
  • Dual filtration system combines carbon filtration, ion exchange, and sub-micron filtration to produce great-tasting, healthy water from your kitchen tap.
  • Leaves natural trace minerals in water for healthier water. (Water that's stripped of minerals, such as distilled water, will rob your body of minerals.)
  • Installs in just minutes and requires no maintenance! Simply replace the filter cartridge after 6 months.
  • Sleek design blends into the kitchen, and the optional under-sink conversion kit allows you to place it under the sink and out of the way.
  • Switch from filtered to unfiltered water with the touch of a button.
  • Third-party tested & certified by the California Department of Public Health Services.
  • 100-day replacement warranty against defects in materials and workmanship.

Aquasana AQ4000 Water Filter Reviews

I installed my Aquasana AQ4000 filter about a month ago, and it's easy to see why this filter has received the Consumer Digest Best Buy Award for five years running.

It took me less than five minutes to install the filter. After letting the water run for a few minutes to flush out the filter, I grabbed a glass from the cabinet.

With my first sip of water, I could taste the difference. Out of curiosity, I filled a glass with non-filtered water from my bathroom sink and compared it to the filtered water from my kitchen sink. Not only could I taste the difference, but I could actually see the difference, too! The filtered water looked pure and crystal-clear compared to the non-filtered water. I sure am glad that I'm no longer cooking with that cloudy, contaminated tap water.

Before installing my AQ4000 filter, I normally drank expensive bottled water - but, because I'm aware that plastic bottles leach dangerous chemicals into water, I wasn't drinking enough water. Now that I have a home water filter, I've been drinking a lot more water, and I can feel the difference. My mid-afternoon headaches are less frequent, the stiffness of my neck has improved, and I've lost a few pounds. Even my house plants are looking healthier since they've been getting watered with pure, chlorine-free water. This home water filter is certainly the "best buy" I've made in a long time!

My only complaint is that hot water can damage the filter, so you have to remember to turn off the filter before turning on the hot water. But this is a minor complaint, especially since you can easily turn off the filter with the push of a button. All things considered, this seems to be the best affordable, hassle-free home water filter out there.
