Whole House Filters

Sediment filters, carbon filters, filter housings, and complete house filtration systems. One installation point, clean water everywhere.

A whole house water filter sits at the point of entry to your home, treating your tap water before it reaches any fixture. That means every faucet, showerhead, water heater, and appliance gets the benefit of filtered water from a single house water filtration system. There is no need to install separate water filters at each point of use.

The most common house water filter system pairs a sediment filter with a carbon filter. The sediment stage catches dirt, sand, rust, manganese, and larger particles that wear down plumbing and fixtures over time. The carbon stage, typically an activated carbon block, strips chlorine, reduces chemical taste and odor, and addresses the water quality issues that municipal water treatment leaves behind. Homes dealing with hard water, scale buildup, or hydrogen sulfide may also want to pair their house filtration system with a water softener or a targeted reverse osmosis system for drinking water.

Big Blue Whole House Replacement Filters and Housings

Big Blue is the industry standard for house water filtration. The 4.5-inch cartridge format provides greater capacity and maintains water pressure even in homes with multiple bathrooms or high demand. We carry sediment filters in 10-inch (W303) and 20-inch (W304), KX Matrikx carbon blocks in 10-inch (W301) and 20-inch (W302B), and Pentek Big Blue housings in both sizes (W305H and W306H). All cartridges are compatible with Ametek, Pentek, and other standard Big Blue housings.

For a complete replacement filter or a water filter replacement on a different schedule, we offer individual cartridges so you can swap sediment and carbon on their own timelines without buying a full kit every time.

For homeowners who want a dedicated house water filter system from a recognized brand, we stock compatible 3M Aqua Pure house filters and drinking water systems. These filtration systems handle chlorine, sediment, and contaminants in a single integrated unit, and they work well as a primary water filtration system or alongside a reverse osmosis filter for dedicated drinking water at the kitchen faucet.

When to Replace Your Whole House Filters

Replace sediment filters every 3 to 6 months and carbon filters every 6 to 12 months. Homes on city water with standard treatment can lean toward the longer intervals, while well water systems or areas with heavy metals, manganese, or high sediment will need more frequent water filter replacement. A drop in water pressure throughout the house is the most reliable indicator that a sediment cartridge has reached capacity.

A house filtration system that runs past its replacement schedule affects water quality at every tap simultaneously. Our AutoShip program sends house replacement filters on the schedule you set, so your whole house filtration never lapses.
