Frequently asked questions
What does this under-counter water filter remove?▾
The PP cotton effectively reduces rust, sand and large particles. The granular activated carbon filter reduces chlorine, taste and odour. The natural carbon block + KDF filter prevents pollutants from accumulating and further improves taste.
Does the TSA reduce TDS?▾
No — the TSA reduces a wide range of contaminants while retaining natural minerals, but it does not reduce TDS. For TDS reduction, choose a Reverse Osmosis system.
What's the difference between WD-TSA and WD-TSB?▾
WD-TSA connects to your existing kitchen faucet (and includes options for under-sink or RV use). WD-TSB comes with a dedicated lead-free brushed stainless steel faucet for high-flow filtered water on demand.
How long does installation take?▾
Less than 3 minutes. The TSA ships with a complete accessory pack and push-in connectors — no plumber and no special tools required.
How do I replace the filters?▾
Filter changes take just 3 seconds thanks to the twist-lock design — pull off the old cartridge and click a new one into the cap.
When should I replace the filters?▾
PP filter every 6 months, GC filter every 8–12 months, and CT filter every 12–18 months. Replacing on schedule keeps performance high and avoids secondary contamination from expired media.
