Question: Do the Aquasana products remove fluoride?

Answer: Both the AQ-4000 and the EQ-300 will reduce fluoride by 40-60%. This is accomplished with the activated coconut shell carbon. Activated carbon will remove 2 of the 4 fluorine isotopes, which will typically lower fluoride levels to below .5 ppm.

Question: How do I remove the A-cartridge from the AQ-4000 if it is stuck?

Answer: Because it is very important that the A-cartridge not be bypassed by the untreated water, the AQ-4000 forces a strong seal on the A-cartridge. If you are having difficulties removing your A-cartridge, all you need to do is fold up a towel on your kitchen counter, and with the A-cap removed, give the filter a light tap on the counter, and the cartridge should jump right out. If this does not work for you, please call our 1800 number at the top of your screen.

Question: If I'm the only one using the filter, can I wait 12 months to change the cartridges?

Answer: The AQ-4000 is certified to treat 500 gallons, which means that we had to prove the performance through 1000 gallons to give you a built-in safety window. Even a family of 6 is unlikely to use a full 1000 gallons in a six-month period. Carbon is the building block of life, and will allow bacteria to colonize on its surface as soon as it gets wet. Unlike the AQ-4100 and EQ-300, which use KDF-55 (55% copper, 45% zinc), the AQ-4000 does not contain anything to inhibit bacteria growth. We no longer use KDF-55 in drinking-water filters because high levels of copper are not good for the brain. Some companies use silver to prevent bacteria build-up, but recent studies have shown that silver has similar health effects to lead. Silver collects in the left testicle or the left ovary and can cause hypertension, brain damage, and other negative health effects.

Companies that use silver in their cartridges must register their products with the FDA as a pesticide. Because there is nothing toxic in our cartridges to prevent bacteria growth, the AQ-4000 will reach detectable levels of heterotrophic bacteria after 7-8 months, and dangerous levels after 12-14 months. To prevent bacteria build-up, the AQ-4000's cartridges should be changed every 6 months, regardless of use. The KDF-55 used in the AQ-4100 and the EQ-300 prevents them from growing bacteria, so a single person using the AQ-4100 Pure Shower System can go a full year between cartridge replacements, and the Rhino EQ-300 can be used until your water bill shows that you've used over 300,000 gallons.

Question: What is the biggest complaint you hear about the AQ-4100.

Answer: The AQ-4100 is one of the top rated shower filters on the market. I will say that the biggest complaint is the carbon that comes out of the filter when you first hook it up and install it. Make sure you read the directions before you install the AQ-4100. Make sure you hold a bucket up to head of the filter and run the water through it for a minute so that the carbon can run into the bucket.

Question: What kind of media is in the EQ-300?

Answer: The bottom cylinder of the EQ-300 is comprised of coconut shell carbon and bituminous carbon. The top cylinder of the EQ-300 is comprised of KDF-55. This media is a copper-zinc alloy media that is specifically designed to reduce chlorine, microorganisms, and heavy metals from drinking water.

Product Update

We hope to launch our AQ-7000 inline filter for icemakers and drinking fountains at the end of August. Testing is going very well, and we are confident that we will end up with a 300 gallon certified claim for lead, chlorine, cysts, THMs and VOCs with a standard 1 year replacement claim. This product will support the claim of being "the most effective inline filter in the industry."We have been working on this design for more than 2 years and are confident that we've come up with a winning design and a structurally secure housing.
