Why 0 TDS?

The cleanest test is the one you can see

TDS (total dissolved solids) is the amount of minerals, salts and metals dissolved in your water. Most pitcher filters use carbon to improve taste. A 5-stage filter adds ion-exchange resin to reduce the dissolved solids a TDS meter measures.

  • See it on the meter. Test your tap water, then your filtered water, and compare the readings yourself.
  • Know when to change it. Replace the filter when the meter reads 006, instead of guessing by the calendar.
  • Five stages, one filter. Carbon handles taste and odor; ion-exchange resin targets the dissolved solids.

Inside the filter

How 5-stage filtration works

Each stage has one job. Together they take water from tap to a lower TDS reading.

  1. 1

    Coarse filter screen

    Captures suspended solids such as dust and rust particles.

  2. 2

    Foam distributor

    Captures more suspended solids and spreads water evenly.

  3. 3

    Carbon + oxidation-reduction alloy

    Reduces chlorine taste and odor.

  4. 4

    Ion-exchange resin

    Reduces dissolved ions: the stage that lowers your TDS reading.

  5. 5

    Non-woven membranes

    Capture ultra-fine particles before water reaches the reservoir.

Results depend on your tap water. Replace the filter when your TDS meter reads 006 or higher.

FAQ

Questions, answered

Everything you need to know about filters, TDS and orders.

Still have a question?sales@zerofilterstore.com
How often should I replace my filter?

Replace your 5-stage filter when your TDS meter reads 006 or higher. How long a filter lasts depends on your tap water: the higher your starting TDS, the sooner you'll need a new one.

Will Zero Filter Online filters fit my pitcher?

They are made to fit pitchers and dispensers that use the standard round 5-stage filter. Check the sizes and specifications on the product page to confirm fit. They don't fit faucet-mount systems. Zero Filter Online is an independent brand and is not affiliated with ZeroWater or Culligan.

What does 000 on the TDS meter mean?

TDS stands for total dissolved solids, measured in parts per million. A reading of 000 means the meter detects no dissolved solids. TDS is a quick check, not a full lab test, and it doesn't measure bacteria.

Is a TDS meter included?

Check the "Includes" list in each product description. You can also buy a TDS meter on its own.

Where do orders ship from, and how long does delivery take?

Orders ship within the United States. Shipping options and delivery estimates are shown at checkout. See our Shipping Policy.

Can I return my order?

You can request a return within 14 days of receiving your item. See our Refund Policy for conditions and how to start a return.
