Filtermart™ Water Filters

FilterMart brings together filtration products from established manufacturers and provides cross-reference support to help identify suitable replacement parts. Options range from fine filtration to higher-micron sediment applications, supporting drinking-water stages, appliance prefilters, whole-house systems, and larger industrial filtration requirements.

Water Filter Types and Filter Media

The filter material determines what a cartridge is designed to remove or reduce. Choosing a water filter by application rather than size alone helps ensure that the replacement filter matches the system's purpose.

Pleated and sediment filters capture dirt, rust, sand, and other particulate matter before it reaches fixtures and equipment. Carbon block and granular activated carbon (GAC) filters are used to reduce chlorine taste and odor and improve water quality.

Multimedia filters use layered media to address turbidity and sediment across larger water supplies. Specialty cartridges provide application-specific filtration and polishing where a standard sediment filter is not enough.

A cartridge designed for sediment should not be selected simply because it fits the housing. Likewise, a carbon cartridge intended for taste and odor reduction is not automatically the right choice for every water-quality concern. When the application is unclear, the existing part number, housing specifications, or available water-test information can help narrow the selection.

Residential Water Filters

Residential water filtration can range from a single under-sink cartridge to a complete whole-house system. Sediment filters are commonly used as a first stage where dirt, rust, or sand is present.

Carbon filtration can be used when chlorine taste and odor are the primary concerns, while reverse osmosis and other multi-stage systems can provide additional treatment for drinking and cooking water.

For whole-house applications, water filter selection should consider the home's water source, flow requirements, available space, and the type of filtration already installed. Matching the cartridge length, diameter, micron rating, and connection or head style are important when replacing an existing filter.

Commercial and Industrial Water Filtration

FilterMart also supports larger commercial and industrial water filtration requirements. Applications can include food-service equipment, beverage systems, process filtration, and specialty equipment that requires a specific replacement element.

Commercial users may need filtration for equipment protection, taste and odor control, particulate reduction, or a defined application specification. For these systems, the original manufacturer part number and equipment model are useful starting points when identifying a replacement. FilterMart's cross-reference approach can help simplify replacement sourcing when an original cartridge is difficult to identify or no longer available.

Replacement Water Filter Cartridges and Filter Housings

A replacement water filter cartridge must match the housing and the intended filtration stage. Common residential housing lengths include 10-inch and 20-inch formats, along with larger or double-length configurations for higher-capacity applications.

FilterMart offers cartridge-style elements as well as filter housings and related components. When ordering a replacement, check the existing cartridge dimensions, housing size, part number, and application. O-rings, sump components, and other housing accessories can also be important when servicing an existing filtration system.

If you have an old or discontinued filter, provide the part number or clear product details when requesting assistance. Cross-reference information can help identify a current replacement or compatible option.

How to Choose the Right Water Filter

Start by identifying the water issue and the system you already have. Sediment concerns generally point toward a sediment or pleated filter. Chlorine taste and odor may call for carbon filtration. Larger whole-house applications may require multimedia or other system-specific treatment.

Next, confirm the cartridge dimensions, micron rating, capacity, connection style, and existing part number. For commercial or industrial applications, also consider the equipment manufacturer, operating conditions, and required flow rate.

If you are unsure which replacement water filter fits, FilterMart can use the information from your existing filter or housing to help narrow the available options.

Find the Right Water Filter at FilterMart

Whether you need a replacement water filter cartridge, a filter housing, or filtration for a larger residential, commercial, or industrial application, choosing the correct specification is the first step. Use the existing part number and system details whenever possible, or contact FilterMart for help identifying the appropriate replacement.

FilterMart water filters are available for a wide range of filtration needs, making it easier to source the right product for an existing system or planned application.

Frequently Asked Questions

What micron rating should I choose for a water filter?

The correct micron rating depends on the application and the material being filtered. Sediment applications may use different ratings from carbon or specialty cartridges, so selection should be based on the system requirements rather than micron rating alone.

Can FilterMart help identify an old or discontinued filter?

Yes. Providing the existing part number, cartridge dimensions, housing information, or system details can help with cross-reference and replacement identification.

Do I need a whole-house or under-sink water filter?

A whole-house system treats water throughout the property, while an under-sink system focuses filtration at a specific point of use. The better choice depends on the water concern and where treatment is required.

Does FilterMart supply residential and industrial filtration products?

Yes. The catalog supports residential filtration as well as commercial and industrial applications, including cartridge, bag, coalescer, and specialty filtration products.

How do I choose a replacement water filter cartridge?

Match the cartridge to the existing housing and application. Check the part number, dimensions, micron rating, connection style, and required filtration performance before ordering.

What affects multimedia filter prices?

Multimedia filter prices can vary with tank size, media volume, valve type, required flow rate, and overall system requirements. Larger or application-specific systems may require an individual quote.
