Optimized Title: BLUONICS 4-pack Water Filters for 4.5 x 20 Cartridges

Bluonics' Standard Size 4.5"x 20" (5 Micron) Pleated Sediment Filter offers exceptional performance in removing a variety of unwanted particles from your water. Featuring a pleated design, this filter outperforms traditional wound, spun, melt-blown, and resin-bonded filter elements by providing increased surface area and longer filter life. The pleated structure also contributes to a lower pressure drop, allowing for higher flow rates and the use of smaller filter housings, ultimately reducing capital equipment costs.

Constructed with 100% synthetic filter media and free of binders or additives, this pleated sediment filter ensures no residue or contaminants are left behind. The systematic production process using 100% synthetic fibers ensures consistent performance and reliability. The "depth" filtration provided by the pleated design effectively traps a wide range of sediment particles, including silt, sand, rust, and dirt, up to 5 microns in size, delivering cleaner and healthier water throughout your home or business.

In addition to the pleated sediment filter, Bluonics offers Standard Size 4.5" x 20" Block Activated Carbon Filters (5 Micron) that are equally impressive in their performance. These block carbon filters, made of finely compressed coconut shell charcoal, are superior in adsorption capabilities compared to granulated activated carbon (GAC) filters. The solid-block design forces all water molecules to travel through the compressed charcoal, maximizing the contact time and resulting in exceptional removal of chlorine, herbicides, organic solvents, chemicals, and contaminants that contribute to bad taste and odor.

Bluonics' filters are not only highly effective, but also environmentally friendly and chemical-free, ensuring no impact on the water's pH or taste, color, and odor. With a flow rate of 5-15 GPM (depending on feed water pressure) and a maximum pressure of 80 psi (suggested work pressure under 50 psi), these filters are compatible with a wide range of water purification systems, including those from 3M, APEC, Aquasana, and more.

Backed by a 30-day money-back guarantee and an extended manufacturer warranty, Bluonics provides exceptional after-sales customer support, including lifetime technical assistance from their team in Sacramento, California, USA. Whether you're looking to upgrade your residential or commercial water purification system, Bluonics' pleated sediment and block activated carbon filters offer a reliable and cost-effective solution to ensure your water is clean, safe, and great-tasting.
