How safe is tap water to drink?

Aquasana AQ 4000 COUNTER TOP FILTER is suitable to use with municipal water (tap water). The water in Bangkok municipality is safe as the treatment facilities from which the water comes from has a World Health Organization benchmark for its quality and is carefully monitored. Water quality standards of MWA follow the Guidelines for Drinking-Water Quality of WHO (WHO, 2006).

Water quality standard of Nampapa Lao.  The standard of water produced by the factory is guaranteed and valid according to the authorization of the Department of Food and Drug and Mineral Industries according to WHO standards.

Does this filter gets rid of microplastic?

Although AQ 4000 is NSF Certified, the NSF independent certification standard does not yet offer a standard for microplastics filtration. Municipal water treatment plants cannot remove all entirely. Most micro plastics are 2.5 microns in size.

The good news is the AQ 4000 is equipped with two, Claryum® carbon blocks and they are extruded down to 0.5 microns. This method is known as mechanical filtration and we use it specifically to remove suspended particles. We are not tested and certified for the microplastics removal but since our system is equipped with sub-micron technology, you can feel comfortable that we are reducing the microplastics significantly. If you want to guarantee all is removed, the only way to do that is reverse osmosis that uses a membrane to filter down to 0.001 microns.

Is this filter system good for me?

AQ 4000 Counter Top Filter has been the most compatible drinking water filtration system with the widest range of customers profile so far. The one and only requirement is to have a good water pressure from the faucet on which you want to install the filter.

Our countertop drinking water filter system is very easy to install, and it only takes a few minutes to do; no plumber is necessary. Just carefully follow the instructions and installation video.

How often do i have to replace cartridges and how much do they cost?

We recommend replacing the cartridges after six months or 450 gallons, whichever comes first. Replacement filters cost 2,380.00 THB.

Is this purified water?

No, and actually, purified water is not as healthy as filtered water. Purified water undergoes reverse osmosis or distillation, which strip everything out of your water – not only the contaminants, but also the healthy, natural minerals. Our system uses selective filtration designed to reduce contaminants from the water and leave in the natural healthy minerals like calcium, potassium, and magnesium.

How do i recycle the replacement filters?

Aquasana USA can recycle the filters for you, but we do not cover the shipping cost to return the filters back to them. In reality, the environmental impact of shipping the filters back to them outweighs the good of recycling. To recycle the AQ-4035 drinking filters yourself, remove the ends of the filters, recycle the plastic parts (which are appropriately numbered) and put the carbon either in your compost pile or garden (carbon is good for plant life), or just throw it out (since the carbon degrades quickly, and is a positive component in a landfill).

I'm a renter, so i can't drill or modify the plumbing. Which filter system should i get?

What does TDS mean?

TDS is the acronym for Total Dissolved Solids, the amount of dissolved minerals and metals present in water. TDS meters tell you the concentration of dissolved minerals and metals, but are not an accurate measurement for contamination. Aquasana products reduce and remove harmful TDS like lead, but selectively retain or replace healthy dissolved solids like calcium, magnesium, and potassium.

What is BPA? And why are people concerned about it?

BPA stands for Bisphenol-A, a contaminant found in most plastics. BPA can adversely affect your health if consumed at high levels. Aquasana drinking systems do not contain BPA, and our filtration process reduces existing BPA.

Does having hard water mean it is contaminated?

Hard water is more of a nuisance than a health risk and is not necessarily contaminated. Hard water is generally safe to drink after it has been properly treated.

What is soft water, and is it safe to drink?

Having soft water just means you have a lower concentration of dissolved minerals in the water (primarily calcium and magnesium). Soft water does not mean clean water. Your water can be soft and still contain contaminants.

What is the selective filtration, and how do Aquasana systems filter drinking water?

Selective filtration is the process of sub-micron filtration, micron filtration, adsorption and ion exchange, all of which selectively reduces chemicals, heavy particulates and most dangerous heavy metals from the water while maintaining healthy minerals like calcium, magnesium and potassium.

How do i know if Aquasana system will be compatible with my faucet?

The only faucets the AQ-4000 water filtration system will not be compatible with are the 2-in-1 faucets that have a detachable sprayer at the faucet opening. The AQ-4000 will fit most standard faucets and also comes with two adapters. If your faucet happens to be a non-standard size than the hose connection or adapters that come with unit, you can take your aerator to the plumbing section at your local hardware store and have it measured. After you know the size of your aerator, we may be able to help you find an adaptor suitable for your needs.
