A simple way to get certified lead-reducing water straight from a standard kitchen faucet. Pull-out and handheld sprayer faucets cannot take it, so check the faucet first.

Overview
Kitchen sinks with a standard faucet are where this filter clicks on, putting filtered drinking water on tap without a pitcher. A lever on the housing flips between filtered and unfiltered flow, and a light signals when the cartridge is spent. Installation needs no tools.
PUR backs the lead claim with WQA certification and the wider contaminant list with NSF, so the filtered water carries documented ratings. Cartridges run out quickly in a busy kitchen, and only genuine PUR replacements are certified for this housing.
Who it's for
Renters and homeowners who drink from the kitchen tap and cannot change plumbing get filtration in minutes. RV owners with a vertical faucet can use it too. Households filtering large volumes for cooking every day will replace cartridges often.
Pros and cons
- Clicks on without tools
- Lever switches filtered and tap water
- Change light flags a spent filter
- WQA certified for lead reduction
- Not for pull-out or handheld faucets
- Only genuine PUR cartridges are certified
- Short cartridge life for heavy users
- Flow rate not listed
Performance notes
Water runs through the cartridge only when the lever is set to filter, so rinsing and dishwashing water do not use up capacity. The cartridge's resistance governs how fast filtered water flows. The change light signals when the cartridge reaches the end of its rated life.
