Under-sink ultrafiltration water filter
Under-sink ultrafiltration water filter FP3-K1: 4 filtration stages with a 0.01 µm UF membrane for water free of bacteria and odour
Under-sink ultrafiltration water filter FP3-K1 – clean drinking water without bacteria and unpleasant odour
The under-sink ultrafiltration water filter FP3-K1 is a household filtration system installed under the kitchen sink, with filtered water served from a dedicated tap. According to the seller, it removes coarse and fine particles, organic matter, partly limescale, chlorine, rust, bacteria and viruses, and improves the smell and taste of the water. The water is said to be softer while retaining the minerals the body needs. All installation fittings are included.
Ultrafiltration works with a membrane with extremely small pores that holds back bacteria, viruses and other microorganisms. Unlike reverse osmosis, it does not remove dissolved minerals, so the water keeps its natural mineral composition. The page states that the system is cheaper than comparable filters while meeting international quality requirements; it provides no certificates.
- 4 filtration stages: sediment, STFE, carbon block and UF membrane.
- UF membrane holds back particles down to 0.01 µm.
- Keeps minerals, unlike reverse osmosis.
- Standard cartridges you replace yourself.
- Under-sink installation in a 40 cm wide cabinet.
Four filtration stages: under-sink ultrafiltration water filter
In the under-sink ultrafiltration water filter, water passes through these stages:
- 5 µm sediment filter removes coarse particles, sand, mud and rust,
- STFE cartridge reduces limescale and excess iron,
- carbon block removes chlorine, pesticides and organic substances and reduces some heavy metals,
- UF membrane holds back particles down to 0.01 µm, including almost all bacteria, viruses and cysts.
Claims about removing bacteria and viruses are the seller’s claims; the page provides no independent measurements. The page mentions 3 stages in one place and 4 elsewhere; four stages are listed here.
Advantages: under-sink ultrafiltration water filter FP3-K1
The system removes impurities and unpleasant odour and taste but keeps minerals, so it suits everyday drinking and cooking. The cartridges are standard, sterilized and replaced by you. If you need even stronger purification, see the PurePro ERS105 reverse osmosis or the direct flow reverse osmosis 200 GPD, and for a simpler solution the Atlas Bravo PP-LA.
