Water filters were known even in Ancient Egypt, Greece, and Rome. Filtration was carried out by passing water through fabric folded several times, and then boiled. Without it, the water was unsafe to drink. But even modern tap water can be dangerous: chlorine, pesticides, heavy metals, excessive salt content, etc. plus the poor condition of the water pipes. Such a "bouquet" needs additional cleaning with a water filter.
Filter jug
The filter material is a carbon cartridge. For efficiency, ion-exchange resin and silver are also added. The filter removes chlorine, its compounds, salts, and heavy metals from the water. Characteristics:
- Low throughput — 1 liter in 5 minutes.
- The filter capacity is 1-5 liters.
- High frequency of changing cartridges — after 1-3 months, resource — 100-400 liters.
- Affordable.
- Mobility.
- Not a high degree of purification, suitable for low pollution.
Attachment on the crane
The filter also consists of a carbon cartridge that can contain ion-exchange resin, silver, and other disinfecting substances. Features:
- Throughput — 0,5 l/min.
- The frequency of replacement of cartridges is 3 months, the maximum resource is 1,5 thousand. liters
- Affordable.
- Takes up little space.
- Mobility.
- Sufficient only in conditions of low water pollution.
Sink filter
Such water filters can have 2 stages of purification: mechanical and sorption, where the ion-exchange component is also used. Characteristics:
- Throughput — 1 l/min.
- The frequency of changing cartridges is 3-4 months. Resource — 2-3 thousand. liters
- Average price range.
- Compactness.
- Separate faucet for water intake.
- Flow filter under the sink
It can have 3-5 degrees of purification. You can choose cartridges that will solve water problems as much as possible.
Features:
- Throughput — 1,5-2 l/min.
- It is necessary to change the cartridges after 3-6 months, the resource is 3-5 thousand. liters
- It is possible to choose such filtration materials that will eliminate existing problems as much as possible.
- The cost depends on the degree of water purification and the number of cartridges.
- High quality cleaning.
reverse osmosis filter
Reverse osmosis cleans the water as much as possible. It has up to 7 stages of purification, including mineral enrichment and structuring. Characteristics:
- Throughput — 100-300 liters/day.
- The maximum degree of purification is up to 99,9% of impurities.
- Long service life of cartridges: filter cartridges — up to 9 months, membrane cartridges — up to 2 years.
- High installation cost.
- A high working pressure is necessary — at least 2,8 atm., but preferably 3,5 atm., otherwise it is necessary to use a pump.
The main thing is that the selected installation meets the needs of the owners for water purification.
