As the main ingredient in many recipes and beverages, water affects the quality, consistency and appearance of any product. The 3M High Flow Series Replacement Cartridge, Model HF40-S provides consistent high quality water by reducing particulate, chlorine taste and odor, cyst, bacteria1, and scale. The Sanitary Quick Change (SQC) design allows for fast and easy cartridge change-outs.

• Integrated membrane pre-activated Carbon Technology (I.M.P.A.C.T.) filtration media combines a membrane with a premium activated carbon block to help provide excellent throughput and cartridge life
• Third-party certifications, such as NSF and WQA, are an advantage provided on many 3M water filtration products
• 3M Purification is a known leader in filtration technology recognized for innovation, trust, and quality around the world
• 3M purification is a known leader in filtration technology recognized for innovation, trust, and quality around the world

The 3M Aqua-Pure Whole House Standard Diameter Water Filter Drop-in Replacement Cartridge AP420 for the AP100 and standard and large diameter Stainless Steel Housing Series, is a great choice in water filtration. This standard 2.75 Dia. drop-in cartridge is manufacturer tested and verified to reduce sediment down to 5 micron nominal, as well as scale. Our dual purpose replacement cartridge, the AP420s rigid construction from our proprietary polypropylene manufacturing process, helps to eliminate unloading of sediment due to variances in water pressure, sometimes referred to as water hammer. The scale inhibition media helps prevent scale build-up on water heaters (both standard and tankless styles), as well as down-stream plumbing fixtures. Additional features and specifications include: 5 micron nominal; Flow Rate: 10 GPM/37.9 GPM (housing dependent) ; Average life: 6 months (incoming water quality may affect cartridge life) ; 2.75 in./7 cm by 9.8 in/24.9 cm ; 25-125 psi/172-862 kPa pressure range ; 40-100F/4.4-37.8C temperature range . To maximize system performance and efficiency, regularly scheduled maintenance including replacement of the filter cartridges at the required interval, at the rated capacity, or sooner if a reduction in water flow occurs is re.quired. Filter life is dependent on actual use and incoming water quality. (Surfaces that are in contact with water are FDA CFR-21 compliant).

• Reduces sediment1 and scale1
• Average cartridge life: 6 months (incoming water quality may affect cartridge life)
• Proprietary polypropylene manufacturing process
• Grooved surface increases total surface area for longer cartridge life compared than non-grooved filter cartridges
• Rigid construction helps to eliminate sediment unloading due to variances in water pressure
• Materials are FDA CFR-21 compliant

The 3M Aqua-Pure Whole House Scale Inhibition Replacement Water Treatment Cartridge AP431 for the AP430SS was designed to reduce scale build-up on hot water-using appliances such as water heaters (standard and tank-less), clothes washers and dishwashing machines and on plumbing fixtures like faucets, pipes and shower heads. The AP431 is as easy to change-out as a light bulb. Easy change-out makes system maintenance easy.

• Polyphosphates, included in this product, help to inhibit scale buildup in hot water heaters (both standard (gas or electric) and tank-less styles) and boilers
• Helps extend the life of hot water heaters and hot water using appliances, pipes and downstream plumbing fixtures such as faucets and shower heads
• By inhibiting scale buildup on heat elements, helps maintain water heater efficiency
• Rated for up to 10 Gal. per minute (GPM)
• System has a pressure range of 25 psi - 125 psi (862 kPa) and operating temperature of 40 degree F - 100 degree F (4.4 degree C - 37.8 degree C)
