How often should I change my filter cartridges?

Sooner or later, after installing a water purification filter, the replaceable cartridges need to be replaced. Usually, such a need arises when an unpleasant taste of water is already felt, there is a smell, or sediment appears. It is not worth delaying the replacement of cartridges until such a moment; they should be changed in accordance with the replacement regulations established by the RO Service near me. Let’s consider the main terms for replacing replaceable modules for water purification filters.

Reverse osmosis

Let’s divide the replacement of cartridges into three stages:

1. Prefilter replacement ​​is usually carried out every six months. Prefiltration cartridges (those installed before the membrane) must be replaced in a timely manner to avoid membrane clogging and premature failure. The membrane is the most expensive element of reverse osmosis. The cost of prefilters ranges from 540 to 1500 rubles, depending on the model of the water filter.
2. The membrane is replaced once every 1.5-2 years, while all filters are replaced. The cost of the membrane is from 900 to 2500 rubles.
3. It is replacing the post-filter element. It is recommended that this element be replaced annually. It may coincide with the simultaneous replacement of prefilters or the complete replacement of all cartridges. The cost of this element is from 390 to 600 rubles.

Three-stage flow filter

Typically, the resource of such a filter is about 6000 liters. Filters are changed simultaneously at least once a year. It is recommended that the first mechanical cleaning cartridge be changed once every 3-4 months; the softening cartridge is changed as its resource is exhausted. In the spring, the softening cartridge is subject to heavy load due to the high hardness of the source water. Accordingly, its resource can be only 150-200 liters.

Filter jug

The service life of the replaceable module for the filter jug ​​is from 170-400 liters of water. We recommend changing the cartridges at least once every 1-3 months, depending on the intensity of use. Remember, the more often you change the replaceable module, the cleaner the water.

Replacing cartridges

Timely replacement of water cartridges is the key to your health!

Take care of your health now because:

• If not replaced promptly, bacteria begin to multiply in the filter flasks, which can get into the purified water;
• Filtration slows down significantly or stops altogether;
• Damage to water filter elements is possible;
• The quality of water purification decreases.

If the filter modules are not changed in time, the water filter will become not only useless but also unsafe for your health.

Mainline filters

Primary filters clean water from large particles such as sand, rust, and other suspended matter. Primary filters include polyphosphate backfill filters for softening water directly before the boiler (for preparing hot water) or before the washing machine (to prevent scale formation during washing).

Filter accessories

Water filter components. This category includes products such as membrane tanks, under-sink system connection units, drainage clamps, 1/4 tubes, flask keys, flasks, flow limiters, check valves, 4-way valves (shut-off valves, automatics), and clean water taps.

Reverse Osmosis Systems

Reverse osmosis systems — filters under the sink in the apartment purify water from 99.9% of impurities, making the water crystal clear and eliminating its unpleasant taste and smell. This technology is based on a physical phenomenon — osmosis. In such filters, water is filtered very slowly (usually up to 190 liters per day — for household systems). A storage tank is used to speed up the selection of filtered water, which accumulates the required amount. After cleaning and storing in the tank, the water at the outlet is additionally processed by a carbon filter or, increasingly, a mineralizer. Reverse osmosis systems have 4 to 5 stages, which is enough for additional purification of ordinary city water. It is not recommended to choose reverse osmosis systems that are not equipped with prefilters or with prefilters with a small resource.
