Product description


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, elminiating 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.

FDN2 Filtration for high nitrates

The FDN2 has all the same capabilities as the FAM1 filter, plus it can remove higher levels of nitrates. 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 FDN2 filter is suitable for water with nitrate levels over 50mg/L. For lower nitrate levels, use the Dionela FAM1 filter. If you also want to reduce water hardness, use the Dionela FTK3.


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 sincks and adaptors.

Replaceable filter

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

Nitrate level (mg/l) / Filter capacity (liters)

  15 | 1600
  25 | 1140
  40 | 760
  60 | 550
  80 | 410
100 | 350
150 | 240
200 | 170

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.
