However, many popular brands cost several hundred dollars. Amazon’s Purewell gravity water filter is a more affordable alternative, and now it’s on sale for even less.The Purewell 2.25-Gallon Gravity Water Filter System usually retailed for $148, but is now available for only $118. The 20% discount applies to the stainless steel countertop system with two filters, a stand and a water-level spigot.More than 300 shoppers purchased the system over the past month, according to Amazon, where it holds a 4.5-star rating from more than 750 customers.Purewell 2.25G Gravity Water Filter System$148.99 $118.99Purewell’s gravity water filter reduces chlorine without removing dissolved minerals$118.99 at AmazonWhat makes gravity water filters different?One reason people choose gravity-fed systems is that they can filter common unwanted substances without removing all of the naturally occurring minerals from the water.The Purewell system does not add minerals. Instead, it leaves dissolved minerals in the water because it does not lower total dissolved solids, or TDS. This distinguishes it from reverse osmosis systems, which can remove beneficial minerals along with unwanted contaminants.Purewell uses two black carbon filters with three-stage filtration. Each filter combines a 0.01-micron hollow-fiber ultrafiltration membrane, a silver-ion membrane and an activated-carbon block.According to Purewell, the system reduces up to 99% of chlorine and filters rust, sediment, organic matter and certain heavy metals. The activated carbon helps improve the water’s taste and smell, while the ultrafiltration membrane captures smaller particles.How does the Purewell gravity water filter work?Users pour tap water into the upper chamber, where gravity moves it through the two filters and into the lower chamber. Filtered water can then be dispensed through the stainless steel spigot.The system requires no electricity or under-sink connection, making it easy to use in houses, apartments and rental homes. While everyday filtration is its primary appeal, its electricity-free operation can also be helpful during power outages or emergencies.Purewell says the system can filter up to four gallons of water per hour. Its two included filters can process up to 6,000 gallons combined, although the brand recommends replacing them every six months for optimal performance. Actual filter life can vary based on water quality and household usage.The 2.25-gallon stainless steel system also includes a transparent window that shows how much filtered water remains without requiring users to remove the lid.For households that want to reduce chlorine and other unwanted substances without stripping away dissolved minerals, the Purewell filter offers many of the qualities associated with more expensive gravity-fed filters for only $118.LEGO’s new pothos plant may be its most realistic botanical yetBlackstone now has a portable air fryer for camping and tailgatingDrew Barrymore’s Walmart appliances now come in ChocolateUGG reinvents its popular men’s Tasman slipper in leatherAlabama fans can shop 16 officially licensed Yeti productsJosie Howell is a commerce and news writer for AL.com where she primarily focuses on shopping and streaming content.
