Frequently asked questions about the Water filters category
Water filters — what are they and what do they do?
Water filters — are devices for purifying water; the category includes pitcher cartridges (AQUAPHOR A5), AQUAPHOR City filter bottles and household/mains filter elements. They remove particulates, chlorine, heavy metal ions and organics, improve taste and protect appliances.
Which filters are suitable for the kitchen and pitchers?
For kitchen use choose AQUAPHOR A5 pitcher cartridges or full AQUAPHOR Provence/Prestige filter pitchers; these remove particulates, chlorine and heavy metals. Typical cartridge capacity ranges ~150–350 L depending on the model.
Which water filters suit a whole house or private house?
Whole-house systems use mains/mechanical filters and modular setups — sediment pre-filters, cartridge housings like Atlas/Geizer and softeners (e.g. Aquaphor A1000) to reduce hardness and protect plumbing. Choose by flow rate and connection diameter.
Which filters to choose for an apartment?
For apartments choose compact filter bottles/pitchers (AQUAPHOR City, Prestige) or under-sink cartridge kits GEYSER/GEIZER with ½" housings. They save space and supply several hundred litres of clean water per cartridge.
Which filter is needed after a reservoir or well?
For reservoir/well water use a multi-stage approach: a sediment pre-filter, then a sorption/carbon block for organics/chlorine, and a softener if needed. Atlas/Geizer housings with GEIZER 3–8 cartridge kits suit multi-layer purification.
What does 'on the water line' mean and which filters are fitted at house inlet?
'On the water line' refers to filters installed at the house inlet: magnetic softeners, coarse mechanical filters and Atlas/Geizer cartridge housings (1"–½"). They protect plumbing and appliances and are typically placed before the meter and heating equipment.
How to check cartridge compatibility with a pitcher or housing?
Check the product description: AQUAPHOR A5 is listed as compatible with Provence/Prestige pitchers. For housings verify connection size (½" or 1") and the compatible cartridge list in the product card.
What materials and technologies are used in AQUAPHOR and GEYSER filters?
AQUAPHOR uses AQUALEN fiber and carbon blocks for chlorine and organic removal; GEYSER offers PP, AR, SVS, BIO cartridges for sediment, sorption and biological protection. Materials include polypropylene, activated carbon and ion-exchange/ fibrous media.
How often should cartridges be replaced and what to base it on?
Replace depending on model and water quality: AQUAPHOR A5 cartridges last ~150–350 L, City filter bottles 100–200 L. Follow the declared cartridge capacity and watch for pressure drop or taste deterioration.
Can the AQUAPHOR CITY filter bottle be used on trips or at a summer house?
Yes, AQUAPHOR CITY filter bottles (0.35–1 L) are compact and leak-proof — suitable for travel and summer houses. They use replaceable cartridges and provide standard drinking-water purification.
What is the difference between B520-12 and Viking B520 Pro cartridges?
B520-12 is an AQUAPHOR basic cartridge for sorption and sediment removal in pitchers/housings; Viking B520 Pro is a reinforced/professional-grade element with higher flow rate and capacity for heavier-duty conditions.
Which filters remove water hardness and how does softening work?
Softening uses ion-exchange cartridges and stationary softeners (e.g. Aquaphor A1000) that replace calcium/magnesium ions with sodium or other ions. This reduces limescale and extends appliance life.
