Why IMRITA Reverse Osmosis?

Here is how ZERO's patented filtration system compares to standard table-top passive (require no power) filters. And yes, we are proud of its performance!

Performance Results and Certification

Culligan ZeroWater’s 5 Stage Ion Exchange Filter is IAPMO certified to reduce PFOA/PFOS, lead, chlorine, chromium and mercury. You can access the certifications, click here.

ZERO Water 5-stage filters underwent rigorous testing, demonstrating significant reductions in the forever chemicals PFOA and PFOS, lead, chromium, and mercury. Our advanced 5-stage filtration system consistently surpasses industry benchmarks and establishes a new standard for water quality.

Water samples were prepared with inorganic non-metal and metal concentrations in accordance with NSF/ANSI standards. For inorganic non-metals and metals tested outside of the NSF/ANSI standard, a concentration of 10 times the EPA’s drinking water limit was used for each compound. The water was then passed through each filter, side by side, at a rate of 1 liter every 90 minutes. After the prepared water was exhausted, a water sample was taken and analyzed to produce the results listed below.

Estimating Filter Life

In order to estimate the longevity of the filter, you need to know the contamination level of the water you are using. Next you can estimate the longevity using the table below.

Use the TDS meter on your tap water to measure its TDS. Use to the table below to estimate how much water your filter can purify before needing a change.

Frequently asked questions

What is TDS and Why measure it?

Measuring TDS (Total Dissolved Solids) levels is the most effective way to assess your drinking water quality. TDS refers to the organic and inorganic particles dissolved in water, which can alter its taste and appearance. These dissolved solids come from various sources, including old pipes, road salt runoff, pesticides, fertilisers, and other sources of contamination.

How Long do Zero Filters Last?

The lifespan of your filter depends on two key factors: the TDS (Total Dissolved Solids) level in your tap water and your daily water usage. TDS measures the concentration of dissolved organic and inorganic substances in your water, which can be checked using a TDS meter.

Lower TDS = Longer Filter Life

Please refer to the section Estimating Filter Longevity for more information.

Filter Replacement Guidelines

• Replace the filter when TDS levels reach 006 PPM or higher.

• A change in the taste or smell of filtered water also indicates it’s time for a replacement. If you notice this, use the TDS meter to verify.

Het is een heel handige oplossing voor goed drinkwater! Geen gedoe met het sjouwen van flessen, en de kwaliteit is heel goed! Wij merken een duidelijke verbetering van voorral ook de smaak. In onze regio kunnen we met z'n tweeën drie maanden met een filter. Dus ook kwa kosten is het een flinke besparing.
