Product description

Dionela FTK3 countertop filter for hard water areas

Dionela water filters are a quick and cost-effective solution for improving the quality of water in your household for drinking, preparing beverages, and cooking. The countertop version sits in a base next to the sink and has its own spigot, elminating the need to purchase a separate faucet. The filtration rate of 1.5 liters per minute offers a ready supply of filtered water for immediate use.

FTK3 filtration for hard water

The FTK3 has all the same capabilities as the FAM1 filter, plus it has a special insert for hard water treatment. It uses a two-stage system to effectively purify your water.  The first stage is a textile-based system which removes physical impurities including dirt, sand, rust, and metal pieces from pipes. The second stage uses bacteriostatically treated granular activated carbon to remove dissolved substances including chlorine, radon, heavy metals, organic substances, detergents, and pesticides. It also improves the taste, clarity, and color of water.

The hard water treatment drastically reduces mineral deposits, which is great for appliances like coffee makers, tea pots, and espresso machines. It's also good for people, as hard water can lead to kidney stones and skin problems.


Simple hookup

Connecting the Dionela water filter requires an adaptor (not included) depending on the type of faucet you have:

For sink-mounted faucets:

  • Connect at the end of the tap with this screw on adaptor with lever
  • Connect at the end of the tap with this screw on adaptor with pull tab

For wall-mounted faucets: You can connect the same way as sink-mounted faucets, or you can use a 1/4" adaptor (available at plumbing and hardware stores) depending on the type of wall-mounted sink you have. See photos in gallery which show two different types of wall-mounted sinks and adaptors.

Replaceable filter

The lifespan of hard water filters depends on the level of minerals in the water. In any case, the lifespan of the FTK3 is much lower than standard FAM1 filters. See the chart below for the approximate capacity before replaceing, depending on the nitrate level.e:

Carbonate level (mmol/l) / Filter capacity (liters)

1,5 | 2400
   3 | 1200
3,5 | 1000
   4 | 900
   5 | 720
   6 | 600

To save money, the filter can be sent in for replacement. The internal filtration elements are removed and replaced for a fraction of the cost of a new filter.
