A Few Words About Activated Carbon

The activated carbon used in the replacement filters is an entirely natural product that visually resembles a fine, odorless, tasteless, and non-toxic black powder. It is produced from coconut shells, making it an environmentally friendly and eco-friendly material. It is heated in a controlled environment and vacuum to achieve its characteristic porous surface. These tiny holes, or pores, can increase the surface area of carbon from 500 to 1500 m2/gr. Due to this processing, it can bind various substances that come into contact with it, in liquid or gas form, in quantities multiple times its weight. One cubic centimeter of activated carbon has the same surface area as a 50,000 square meter surface.

"How do I choose the right replacement filter for my area?"
The replacement filters included in your package are suitable for most areas of Greece, but your device is also compatible with many other filter types. On each product page, you’ll find all available replacement filters with photos, summaries, and links for more details. If you’re not sure which filter is best for your area, simply contact us—we’ll be happy to help!
"Should I choose a countertop or under-sink filter?"
This depends on your available kitchen space and your needs. Countertop filters can be connected by yourself in seconds, but they take up space on the counter. Under-sink filters save counter space but usually require installation by a technician or plumber.
"I don’t know if I need a single, double, or triple filter."
If your problem is just taste or odor, a single filter is enough. If you also have sediment, you need a double filter—first stage for sediment, second for carbon. If you have limescale, sediment, and bad taste, a triple filter is recommended. For wells, islands, or very challenging water, we suggest a reverse osmosis filter. If you’re not sure, just contact us!

Leave it to us! We’ll call you when it’s time to change your filter.
