Thank you for visiting our online store for a remanufactured HP ink cartridges. Each HP ink cartridge is remanufactured with environmentally friendly, waterbased ink, from some of the leading remanufacturing companies of quality HP cartridges. These companies have developed a sound remanufacturing method to ensure the quality and the consistency of each remanufactured HP black cartridge or HP color cartridge. Not all cartridges are remanufactured equally. What these companies do, that others do not - All HP ink cartridges are remanufactured exclusively with fully tested and qualified empties. A recycled HP black ink cartridge or a HP color inkjet cartridge must be in excellent condition and free from electrical and visual defect before they make it to the production floor. This is critical because you can't make a quality HP deskjet ink cartridge, HP officejet ink cartridge or HP photosmart printer ink cartridge from poor quality raw materials. Each remanufactured HP black inkjet cartridge or HP tri color cartridge is recycled on state-of-the-art equipment designed and developed to uniquely clean and remove old ink from each cartridge using a reverse osmosis water filtration system. Cartridges are refilled with new ink and each cartridge is tested prior to shipment to you, so that print quality equals, or exceeds, the quality offered by an original HP printer cartridge. More than two ounces of oil are used for the production of every HP black inkjet cartridge or HP tri color cartridge. That means we are going through 4,000,000 gallons of oil for single-use cartridges each year. Purchasing remanufactured HP ink cartridges from our online store helps to stagger the amount of plastic dumped into our nation's landfills by 66-75%, helping to reduce our petroleum consumption and helping to save us millions of tax dollars needed to pay for additional landfill management. We are pleased to offer free US Priority Mail, FedEx or UPS Ground from our distribution facilities in California and Tennessee.
