Some FAQs will help clear any doubts left in your mind about water filtration products.

Q: How does the Zero filter work?

A: Zero works in a 5 stage process. Each stage is designed in such a way to ensure that you are left with pure water fit for drinking purposes.

Stage 1: A coarse filter screen filters out fine particles and any sediment present in the water.

Stage 2: At stage 2, foam distributor disperses water more evenly across the entire width of the filter. This increases the filter’s ability to remove contaminants more effectively.

Stage 3: When the water reaches stage 3 of the filtration process, here, carbon and oxidation reduction alloy filter out and reduces the chlorine content, improve the taste, and prevent mold from forming when the filter is moist.

Stage 4: The dual comprehensive ion exchange resin helps in stripping foreign ions from the water molecules and brings it to the pure state.

Stage 5: At the last stage, the ultra-fine screen and membrane layers remove any fine particles left in the water.

All these stages help you in getting tasty and healthy water.

A: Yes, as it is a 5-stage process, it takes more time to filter water, but the results are far better than the 2 stage process.

Q: Is the tumbler unbreakable?
