PUREPLUS 5 Micron 20in x 4.5in Whole House Filter Combo Kit - Clean

Our review of the PUREPLUS 5 Micron 20in x 4.5in Whole House Water Filter Cartridge Combo Kit finds it best suited for homeowners who want an affordable, straightforward way to improve water quality across their home. The single biggest reason to buy is the combination of a sediment filter and an activated carbon block at a 5-micron rating, which removes visible particles, reduces chlorine taste and odor, and tackles common impurities with minimal fuss. Installation is simple and the cartridges are built to fit standard 4.5in x 20in housings, making these a practical replacement option for many existing whole-house systems.

Key Features

• Dual-stage filtration: The combo includes both a sediment filter and an activated carbon block to address particles and chemical tastes for cleaner water throughout the home.
• 5-micron rating: The 5 micron sizing traps sand, rust and other debris while still allowing good flow for household use.
• Universal fit: Designed for standard 4.5in x 20in housings and compatible with many common replacement model numbers, so swapping is generally hassle-free.
• Improved taste and odor: The carbon block specifically reduces chlorine and related odors, which noticeably improves drinking and cooking water.
• Easy installation: Straightforward replacement process keeps maintenance quick for most DIY-minded homeowners.
• Durable construction: Built to provide reliable, consistent filtration over a typical cartridge service life for routine household needs.

Who It's For

This kit is ideal for homeowners with standard 4.5in x 20in whole-house filter housings who want an economical replacement that improves water clarity and taste without changing plumbing or housings. It works well for families on a budget who need dependable sediment removal and chlorine reduction across showers, faucets and appliances.

Those with very high particulate loads, heavy iron staining, or specialized contaminant concerns should consider a dedicated iron or micron-rated specialty system instead. Likewise, consumers seeking NSF-certified warranties or cartridge lifespans specified to exact gallons may prefer branded OEM cartridges with published certifications.
