Brita Standard Water Filter Instruction Manual
Model: 35503 | Brand: Brita
Introduction
The Brita Standard Water Filter is designed to provide healthier, great-tasting tap water by reducing common impurities. This BPA-free filter utilizes ion-exchange resin and activated carbon to significantly cut the taste and odor of chlorine, and reduce copper, cadmium, and mercury impurities. By choosing Brita, you contribute to reducing plastic waste, as one filter can replace up to 1,800 standard 16.9-oz. plastic water bottles annually.

- Easy Installation: Designed for quick and simple setup without presoaking.

Setup
- Prepare the Filter: Wash your hands thoroughly before unwrapping the filter.
- Flush the Filter: Hold the filter under cold tap water for 15 seconds to flush out any loose carbon dust.
- Insert the Filter: Firmly insert the flushed filter into the reservoir of your Brita pitcher or dispenser. Ensure it is seated correctly to prevent unfiltered water from bypassing it.
- Initial Fill: Fill the reservoir with cold tap water. Discard the first 3 pitchers of filtered water, or use this water for non-drinking purposes like watering plants. It is normal for carbon dust to appear in your first few fillings.

Operating Instructions
Once the filter is properly installed and primed, your Brita system is ready for use. Simply fill the top reservoir with cold tap water, and the water will slowly filter through to the main pitcher/dispenser below. The filtration process is gravity-fed, ensuring thorough contact with the filter media.
How the Filter Works:
- Ion-Exchange Resin: Helps to reduce impurities like copper, cadmium, and mercury in your water.
- Activated Carbon: Reduces chlorine, which improves the taste and odor of your water.
- Built-in Mesh Screens: Prevent black flecks from appearing in your filtered water.

Maintenance
For optimal performance and the best-tasting water, it is crucial to replace your Brita Standard Water Filter regularly. One filter is designed to last approximately two months or filter 40 gallons of water, whichever comes first. Consistent replacement ensures effective reduction of impurities and maintains water quality.
To replace, simply remove the old filter by pulling it up from the reservoir. Dispose of the old filter responsibly (Brita filters are recyclable through programs like Preserve's Gimme 5 Program). Then, follow the setup instructions for installing a new filter.

Troubleshooting
If you notice a change in the taste or odor of your filtered water, or if the filtration speed significantly decreases, it is likely time to replace your filter. These are common indicators that the filter media has reached its capacity and is no longer effectively reducing impurities.
Ensure the filter is properly seated in the reservoir. A loose filter can allow unfiltered water to bypass the filtration process. If issues persist after replacing the filter and ensuring proper installation, please refer to the support section for further assistance.
