Drop-in filters for filter housings: sediment, activated carbon and carbon block

Drop-in filters are replaceable cartridges installed inside filter housings. They are used to retain sediment, sand, rust, suspended particles, chlorine, unwanted odors and unpleasant tastes, depending on the type of cartridge installed.

Cartridges installed inside a housing
Drop-in cartridges do not work alone. They must be installed inside a compatible filter housing. The housing keeps the cartridge in place and allows water to pass through the filter media.

Standard sizes
Cartridges are available in different heights and diameters, including standard and Big sizes. Before replacement, it is important to check length, diameter, housing type and available installation space.

Scheduled replacement
When the cartridge is exhausted, it must be removed from the housing and replaced. Service life depends on treated liters, incoming water quality and the type of filter media.

Sediment cartridges
They retain sand, rust, silt and solid particles. They are often used as the first stage to protect downstream filters, membranes, valves and equipment.

Granular activated carbon
Granular activated carbon cartridges are used to improve water taste and odor and to reduce substances that may affect the flavor of water.

Carbon block
Carbon block cartridges provide compact and uniform filtration. They are suitable when finer filtration and a larger contact surface with carbon are required.

Washable or pleated cartridges
They can be used when sediment and particle removal is required with a larger filtering surface. Selection depends on the filtration rating and application.

Cartridge size
Always check height, diameter and compatibility with the installed filter housing. An incorrect cartridge may not seal properly or may not filter correctly.

Filtration rating
The filtration rating, expressed in microns, must be selected according to incoming water quality and the level of protection required for the system.

Flow rate and pressure drop
A cartridge that is too fine or undersized may reduce flow rate and create pressure loss. For professional systems, correct filter sizing is important.

Helpful tip:
Before replacing a drop-in cartridge, shut off the water, release pressure, check the housing gasket and make sure the new cartridge is the correct size.
