Everflow Diatom Granular Filter
The Everflow filter is our most efficient filter, providing comprehensive improvement and protection of your water quality, great flow rates and a long service life with two layers of filtration: ceramic shell encapsulating granular carbon filtration media. Made in the USA for Sertodo.
We recommend these filters for water sources not heavily impacted by agriculture or industry, (either municipal, well or surface water) or to improve the taste and quality of your municipal water, removing chlorines and fluorides while offering additional protection against pharmaceuticals and other contaminants. Excellent sediment filtration.
These filters use a two step filtration process:
- Diatomaceous Earth Ceramic Shell infused with silver features a microscopic, porous honeycomb structure that provides ultra-fine physical filtration down to .2 microns. This complex matrix traps fine sediment and microscopic impurities including protozoa and bacteria. The ceramic can be cleaned and scrubbed throughout it's life to remove clogging and improve flow rates, while the silver infusion helps to prevent biofouling.
- Granular Carbon Filtration Core specially treated to remove fluorides and chlorines added to municipal water systems as well as heavy metals, herbicides and pesticides, VOC's, pharmaceuticals, endocrine disruptors, PFOA/PFOS, taste/odor compounds and more.
*No activated alumina is used in the filter element.

Copper Care Instructions
Daily Care
our pure copper pieces are designed to last generations with proper care.
- Hand wash with warm water and mild dish soap
- Dry immediately with a soft, clean cloth
- Avoid harsh detergents, abrasive cleaners, or dishwashers
Restoring Shine
Over time, copper naturally develops a rich patina. To restore its original luster:
- Create a paste using lemon juice and salt
- Gently rub onto the surface with a soft cloth
- Rinse thoroughly and dry immediately
- Alternatively, use a copper-specific polish
Natural Patina
The darkening of copper is a natural process that doesn't affect its quality or health benefits. Many cherish this aged appearance as it adds character and proves authenticity. You can choose to maintain the shine or embrace the patina—both are beautiful.
Storage
Store in a dry place. If stacking multiple pieces, place a soft cloth between them to prevent scratching.

FAQs
Is this real copper or copper-plated?
Every piece is crafted from 100% pure, solid copper. Never plated or mixed with other metals. We verify the purity of each batch to ensure you receive authentic copper with all its natural health benefits.
Why does copper change color?
Copper naturally develops a patina (darkened appearance) over time when exposed to air and moisture. This is normal and doesn't affect quality or health benefits. Many people love the aged look, while others prefer to polish it back to a shine, we think both are beautiful and authentic.
Is it safe to drink from copper vessels?
Yes! Copper has been used safely for drinking water for thousands of years in Ayurvedic tradition. Pure copper naturally has antimicrobial properties. However, avoid storing acidic beverages (citrus juices, vinegar) in copper for extended periods. Always rinse after use.
Can I put copper in the dishwasher?
No, we recommend hand washing only. Dishwashers use harsh detergents and high heat that can damage the copper's finish and accelerate tarnishing. Simply hand wash with mild soap and warm water, then dry immediately.

First thing: Compared to our previous BB Ultra Sterasyl filters, these filters have improved flow. Second, the water does taste a bit more pleasant from what I remember of our BB filtered water. Not sure if this due to regency bias, but our Everflow water tastes great. Lastly, they filter out fluoride however our local municipal water has extremely low levels of fluoride to begin with so check your local water report before making a decision.

This is the best. Our city water smells and tastes like it should be used for cleaning toilets and these filters bring us the best tasting water

Recently purchased Four gravity filters and during installation I accidentally broke one of the filters. Sertodo was awesome to replace the filter at no charge. We are very grateful and delighted with the service Sertodo gives.
Thanks for great products and service
